COVID-19 Vaccine Roll-Out in South Africa and Zimbabwe: Urgent Need to Address Community Preparedness, Fears and Hesitancy

Community responses to corona virus disease (COVID-19) in Africa in the face of "Infodemic": A scoping review

Globally, Corona Virus Disease (COVID-19) has significantly affected communities in various aspects. The World Health Organization proposed different measures to prevent the pandemic. However, these measures in some instances have not effectively minimized the impacts of COVID-19, due to innumerable factors, inter alia, considerable "infodemic" related to myths, misinformation, and misconceptions. Knowledge of the "infodemic" on COVID -19 can lead to effective interventions to rid societies of COVID-19, hence reduction of COVID-19-related risks and outcomes. This article explores the "COVID-19 infodemic" that affected community responses to COVID-19 in Africa. The study employed a scoping review approach involving peer-reviewed articles from numerous search engines and databases. The keywords involved in the search query were: "COVID-19 infodemic, COVID-19 false news, COVID-19 in Africa, 'knowledge of COVID-19, 'myths, misinformation, and misconceptions on COVID-19, 'history of COVID-19', 'community responses to COVID-19 in Africa". Findings show that 5G technology transferred coronavirus, high temperature and alcohol can kill coronavirus, blacks are immune to COVID-19, COVID-19 vaccine development has been rushed hence not very effective and safe and also causes infertility. Diverse community responses have been registered which in some ways frustrated efforts in combating the pandemic. Therefore, the "infodemic" consisting of myths, misconceptions, and misinformation have been resulting from the history of COVID-19 which first affected white people more than blacks. Also, low knowledge of how the virus is transmitted and affect human being; and the notion that COVID-19 affects richer than poor people, hence since white people are richer than black people then they were the first to be affected by the pandemic. Obviously in presence of such myths, misconceptions, and misinformation; community responses in combating COVID-19 have not been very effective in Africa. For these interventions to be effective, collective efforts involving various stakeholders to raise awareness of COVID-19 are needed.

"COVID is a huge jigsaw puzzle that I am trying to make sense of myself": Exploring the perceptions towards the COVID-19 vaccine communication strategy in Australia amongst unvaccinated Australian adults

The COVID-19 pandemic and the associated introduction of a novel vaccine has provided researchers with the opportunity to investigate how to support vaccine acceptance and reduce hesitancy using novel approaches. This study aimed to understand the perceptions of COVID-19 unvaccinated Australian adults towards the COVID-19 vaccines and the factors influencing their vaccine decision-making. We also explored their attitudes towards vaccine communication strategies and the availability and quality of resources to support decision-making and preferences during future public health emergencies. In-depth interviews were undertaken with 35 members of the Australian community who self-identified as being unvaccinated against COVID-19 from September to December 2021 and did not intend to vaccinate. Key themes that emerged focused on past experiences of vaccination, feelings of being coerced or pushed into vaccination, concerns about transparency around the development processes used for the COVID-19 vaccines, the value of getting vaccinated and issues regarding the mandates being used. Participants acknowledged that they would be open to talking to peers but held some reservations about the process. Requirements for vaccination have now been lifted in many countries. While governments should continue to strive to promote COVID-19 primary and booster vaccines going forward, this research suggests that there will be a small proportion of the community who continue to actively decline the vaccine. Further work is needed to understand the strategies that can support decision-making during pandemics amongst people who remain uncertain about the need for the vaccines or are concerned about vaccine safety. This includes innovatively exploring the role of peer-to-peer communication and the influence it may have on correcting misunderstandings and supporting confidence.

Vaccine inequity-induced COVID-19 dilemma: Time to sober up

OBJECTIVE

The aim of the study was to discuss the catastrophic consequences of inequitable vaccine distribution and analyze the main challenges to address it, helping to guide efforts to address inequities in vaccine coverage.

METHODS

All published papers written in English were searched through PubMed, Web of Science, and Google Scholar with the combination of relevant terms of COVID-19 vaccine inequity.

RESULTS

In this paper, we first outlined the scope of inequitable vaccine distribution and identify its truly catastrophic consequences. Next, from the perspectives of political will, free markets, and profit-driven enterprises based on patent and intellectual property protection, we analyzed in depth the root causes of why this phenomenon is so difficult to combat. In addition, some specific and crucial solutions that should be undertaken in the long term were also put forward in order to provide a useful reference for the authorities, stakeholders, and researchers involved in addressing this worldwide crisis and the next one.

CONCLUSIONS

Achieving COVID-19 vaccine equity faces funding gaps, vaccine nationalism, and barriers to access to intellectual property and technology. Thus, the scope of global vaccine inequity is immense, and its repercussions will continue to be felt worldwide, especially among the world's most vulnerable residents, both adults and children. Beyond fundamental issues, the growing vaccine hesitancy and unreliable distribution in low-income countries must be addressed.

Examining corruption risks in the procurement and distribution of COVID-19 vaccines in select states in Nigeria

BACKGROUND

Public health emergencies raise significant concerns about corruption and accountability; however, these concerns can manifest in different ways across diverse locations. For instance, more developed countries with a stronger rule of law may experience more corruption in vaccine procurement, whereas developing countries may experience more corruption at the point of distribution and delivery to end users. This research focuses on corruption concerns in Nigeria, specifically examining the procurement and distribution of COVID-19 vaccines.

METHODS

This paper utilizes a scoping review and a qualitative research approach. Key informants (n = 40) involved in the procurement and distribution of COVID-19 vaccines across two states in Nigeria were interviewed. Findings from the scoping review were summarized, and collected data were inductively coded and analysed in themes, revealing clear examples of implementation irregularities and corruption in the country's COVID-19 vaccination processes.

RESULTS

Vaccination programme budgeting processes were unclear, and payment irregularities were frequently observed, resulting in vaccinators soliciting informal payments while in the field. Recruitment and engagement of vaccination personnel was opaque, while target vaccination rates incentivized data falsification during periods of vaccine hesitancy. Accountability mechanisms, such as health worker supervision, vaccination data review, and additional technical support provided by donors were implemented but not effective at preventing corruption among frontline workers.

CONCLUSIONS

Future accountability measures should be evidence-driven based on findings from this research. Personnel recruitment, contracting, budgeting, and remuneration should focus on transparency and accountability.

Testing Likely Response to Behavioral Nudges and Shoves to Promote COVID-19 Vaccine Uptake Amongst Segments of the Unvaccinated Population of South Africa

In early 2022, as the vaccination rate in South Africa slowed, there was a strong need for COVID-19 communications to evolve from mass information and education campaigns targeting the general population, to more targeted approaches to motivate uptake amongst population segments facing convenience, complacency, and confidence barriers.Project Last Mile (PLM) and Ipsos conducted a representative study of the population of South Africa to: (1) understand population segments with regards to their likelihood of getting the COVID-19 vaccine, (2) understand the drivers and barriers around getting the COVID-19 vaccine for each segment; and (3) test the likelihood of adoption of a range of enabling, incentivizing, and mandating behavioral interventions ("nudges and shoves").The study demonstrated that a significant proportion of the unvaccinated population is willing to get vaccinated, given the right conditions. Making it easy and convenient to get vaccinated (enabling) is likely to deliver moderate to strong impact. Ease of access, the ability to take time off from work, the provision of a reservation, and free transportation were the most influential factors in encouraging vaccination for the largest number of people.

A structured literature review of the health infodemic on social media in Africa

Infodemics is a multi-faceted threat that needs to be dealt with by governments during public health emergencies. This strategic review described the role of social media platforms in creating and reinforcing an infodemic during health pandemics in Africa. The inclusion criteria for the review were African research on infodemics on social media during pandemics, epidemics or endemics in the past 10 years. A structured literature review, making use of the Sample, Phenomenon of Interest, Design, Evaluation, Research (SPIDER) scoping review methodology framework, identified scholarly publications from various academic databases. A total of 41 articles met the eligibility criteria. The six factors identified included stakeholders, socio-economic context, conspiracy theories, sources of information, government responses and verification mechanisms. The findings of this study indicate that governments needs to include infodemics in the risk communication strategy for public health emergencies. Verification of misinformation can mitigate the effects of conspiracy theories while the socio-economic context of the audience will influence planning strategies to mitigate infodemics on social media.

Contribution

This study contributes to the knowledge base of risk communication during pandemics in Africa by providing a review of how infodemics on social media have influenced the COVID-19 pandemic on the continent. The results also provide a foundation for the research agenda in this research field that will provide an evidence-based response to the pandemic in Africa.

Validation of the vaccination attitudes examination scale in a South African context in relation to the COVID-19 vaccine: quantifying dimensionality with bifactor indices

BACKGROUND

The COVID-19 pandemic represented a global public health emergency. Existing studies support the view that vaccination and mass immunization are among the most effective means of containing the outbreak and promoting health. However, negative attitudes toward vaccination and the related vaccine hesitancy among many groups have created a significant barrier to effectively managing the health crisis. Having a valid and reliable tool to assess attitudes toward vaccination remains imperative so that factors underlying vaccine refusal can be identified and public health interventions can be facilitated. The current study examined the psychometric properties of the Vaccination Attitudes Examination Scale (VAX) in South Africa.

METHODS

Participants (n = 322) completed the VAX. Confirmatory factor analysis and ancillary bifactor indices were used to examine the hypothesized factor structure (a total scale and four subscales) of the scale. Inter-item correlations, factor loadings, and average variance extracted were used to examine the validity of the scale. Predictive validity was examined by comparing those who had received the COVID-19 vaccine and those who had not. The reliability of the scale was examined in terms of both Cronbach's alpha and composite reliability.

RESULTS

Confirmatory factor analysis provided support for the conceptualization of the scale as consisting of a total scale and four subscales, and ancillary bifactor indices indicated that the subscales accounted for a sufficient amount of variance (44%) after the variance explained by the total scale was considered. Overall, the analysis indicated that the scale had satisfactory reliability (alpha and composite reliability = 0.70) and provided evidence for the construct, convergent, and predictive validity of the VAX.

CONCLUSIONS

The sound psychometric qualities of the scale, when used in a low- to middle-income country, have the potential to advance research and immunization policy within these settings and facilitate more targeted interventions to promote vaccine uptake.

Correlates of COVID-19 vaccination intentions and opinions about mandates among four groups of adults in South Africa with distinct vaccine intentions: evidence from a large national survey

INTRODUCTION

Despite a high number of recorded COVID-19 infections and deaths in South Africa, COVID-19 vaccine coverage remained low in March 2022, ten months into the national vaccine roll-out. This study provides evidence on the correlates of vaccine intentions, attitudes towards vaccination and opinions about mandates.

METHODS

We used data from the second COVID-19 Vaccine Survey (CVACS), a telephone survey conducted February-March 2022 among 3,608 South African adults who self-reported not being vaccinated against COVID-19. The survey instrument was designed in consultation with government, policymakers, and civil society; and segmented the sample into four distinct groups with different vaccine intentions (synonymous with vaccine hesitancy levels). Kruskal-Wallis and Mann-Whitney tests were used to examine the sociodemographic characteristics, attitudes and behaviours associated with the different vaccination intentions groups. Thematic coding of responses to open-ended questions elicited insights on reasons for not being vaccinated and attitudes towards mandates.

RESULTS

Intentions to get vaccinated were greater among individuals with lower socio-economic status (Mann-Whitney Z = -11.3, p < 0.001); those believing the vaccine protects against death (Kruskal-Wallis Χ2 = 494, p < 0.001); and those who perceived themselves at risk of COVID-19-related illness (Χ2 = 126, p < 0.01). Vaccine intentions were lower among individuals who believed that the vaccine causes death (Χ2 = 163, p < 0.001); believed that the vaccine is unsafe for the babies of pregnant/breastfeeding mothers, or the chronically ill (Χ2 = 123, p < 0.01); those not trusting government health information about COVID-19 and the COVID-19 vaccine (Kendall's τ = -0.41, p < 0.01); and those in opposition to mandates (τ = 0.35, p < 0.001). Only 25% supported mandates, despite 48% thinking mandates would work well, with 54% citing individual rights as their main reason for mandate opposition.

CONCLUSION

The profile of individuals not vaccinated against COVID-19 as of March 2022 varied markedly by self-reported vaccination intentions, underscoring the importance of tailored demand-creation efforts. This paper highlights several factors which differ significantly across these groups. These findings could inform the design of future vaccination campaigns, potentially increasing their likelihood of success. This is an important policy objective given widespread vaccine hesitancy, and further work is required on this topic. Mandates remain an option to increase coverage but need to be carefully considered given extensive opposition.

COVID-19 vaccine hesitancy in Latin America and Africa: a scoping review

Vaccination has played an important role in the containment of COVID-19 pandemic advances. However, SARS-CoV-2 vaccine hesitancy has caused a global concern. This scoping review aims to map the scientific literature on COVID-19 vaccine hesitancy in Latin America and Africa from a Global Health perspective, observing the particularities of the Global South and using parameters validated by the World Health Organization (WHO). The review reporting observes the recommendations of the PRISMA for Scoping Reviews (PRISMA-ScR) model. Search was conducted in PubMed, Scopus, Web of Science, and Virtual Health Library (VHL) databases, selecting studies published from January 1, 2020 to January 22, 2022. Selected studies indicate that COVID-19 vaccine hesitancy involves factors such as political scenario, spread of misinformation, regional differences in each territory regarding Internet access, lack of access to information, history of vaccination resistance, lack of information about the disease and the vaccine, concern about adverse events, and vaccine efficacy and safety. Regarding the use of conceptual and methodology references from the WHO for vaccine hesitancy, few studies (6/94) use research instruments based on these references. Then, the replication in Global South of conceptual and methodological parameters developed by experts from the Global North contexts has been criticized from the perspective of Global Health because of it may not consider political and sociocultural particularities, the different nuances of vaccine hesitancy, and issues of access to vaccines.

"It Doesn't Cure, but It Protects": COVID-19 Vaccines through the Eyes of Children and Their Parents

Recently, studies have examined COVID-19 vaccine acceptance and/or hesitancy amongst adult populations across the globe. However, there is a paucity of literature illustrating children's voices in vaccination debates. This article draws on qualitative data collected via a mixed-methods study that explored South Africans' experiences during the COVID-19 pandemic between 2020 and 2021. Interviews were conducted with a purposive sample (N = 29) of children (>18 years) and their parents regarding their initial perspectives on COVID-19 vaccines. Given the dyadic nature of our study, we explored the intergenerational influence that parents' perspectives had on children's vaccine acceptability and the role that vaccine literacy, or lack thereof, played in vaccine decision making. Findings showed a great level of vaccine acceptability among children and parents, where many placed hopes in the vaccines to promote societal health and wellbeing. Intergenerational transfer of perspectives was observed where children's willingness to receive a vaccine was intrinsically linked to their parents' vaccine acceptability. Some participants also expressed concerns about COVID-19 vaccines, related to misinformation, mistrust, and limited vaccine literacy. We discuss the findings as they relate to vaccine and health literacy, also considering the prospective implications of this work as we enter the "recovery" period of the pandemic.

COVID-19 vaccine uptake, confidence and hesitancy in rural KwaZulu-Natal, South Africa between April 2021 and April 2022: A continuous cross-sectional surveillance study

High COVID-19 vaccine hesitancy in South Africa limits protection against future epidemic waves. We evaluated how vaccine hesitancy and its correlates evolved April 2021-April 2022 in a well-characterized rural KwaZulu-Natal setting. All residents aged >15 in the Africa Health Research Institute's surveillance area were invited to complete a home-based, in-person interview. We described vaccine uptake and hesitancy trends, then evaluated associations with pre-existing personal factors, dynamic environmental context, and cues to action using ordinal logistic regression. Among 10,011 respondents, vaccine uptake rose as age-cohorts became vaccine-eligible before levelling off three months post-eligibility; younger age-groups had slower uptake and plateaued faster. Lifetime receipt of any COVID-19 vaccine rose from 3.0% in April-July 2021 to 32.9% in January-April 2022. Among 7,445 unvaccinated respondents, 47.7% said they would definitely take a free vaccine today in the first quarter of the study time period, falling to 32.0% in the last. By March/April 2022 only 48.0% of respondents were vaccinated or said they would definitely would take a vaccine. Predictors of lower vaccine hesitancy included being male (adjusted odds ratio [aOR]: 0.70, 95% confidence interval [CI]: 0.65-0.76), living with vaccinated household members (aOR:0.65, 95%CI: 0.59-0.71) and knowing someone who had had COVID-19 (aOR: 0.69, 95%CI: 0.59-0.80). Mistrust in government predicted greater hesitancy (aOR: 1.47, 95%CI: 1.42-1.53). Despite several COVID-19 waves, vaccine hesitancy was common in rural South Africa, rising over time and closely tied to mistrust in government. However, interpersonal experiences countered hesitancy and may be entry-points for interventions.

Vaccine access, equity and justice: COVID-19 vaccines and vaccination

Although significant progress has been made in achieving goals for COVID-19 vaccine access, the quest for equity and justice remains an unfinished agenda. Vaccine nationalism has prompted calls for new approaches to achieve equitable access and justice not only for vaccines but also for vaccination. This includes ensuring country and community participation in global discussions and that local needs to strengthen health systems, address issues related to social determinants of health, build trust and leverage acceptance to vaccines, are addressed. Regional vaccine technology and manufacturing hubs are promising approaches to address access challenges and must be integrated with efforts to ensure demand. The current situation underlines the need for access, demand and system strengthening to be addressed along with local priorities for justice to be achieved. Innovations to improve accountability and leverage existing platforms are also needed. Sustained political will and investment is required to ensure ongoing production of non-pandemic vaccines and sustained demand, particularly when perceived threat of disease appears to be waning. Several recommendations are made to govern towards justice including codesigning the path forward with low-income and middle-income countries; establishing stronger accountability measures; establishing dedicated groups to engage with countries and manufacturing hubs to ensure that the affordable supply and predictable demand are in balance; addressing country needs for health system strengthening through leveraging existing health and development platforms and delivering on product presentations informed by country needs. Even if difficult, we must converge on a definition of justice well in advance of the next pandemic.

A review of public health, social and ethical implications of voluntary medical male circumcision programs for HIV prevention in sub-Saharan Africa

Ideally, the benefits of public health interventions should outweigh any associated harms, burdens, and adverse unintended consequences. The intended benefit of voluntary medical male circumcision (VMMC) programs in eastern and southern Africa (ESA) is the reduction of HIV infections. We review the literature for evidence of reductions in HIV incidence, evaluate the extent to which decreases in HIV incidence can be reasonably attributed to VMMC programs, and summarize social harms and ethical concerns associated with these programs. Review findings suggest that HIV incidence had been declining across ESA since before the large-scale rollout of VMMC as a public health intervention, and that this decline may be due to the combined effects of HIV prevention and treatment interventions, such as expanded antiretroviral therapy. The independent effect of VMMC programs in reducing HIV infections at the population level remains unknown. On the other hand, VMMC-associated evidence is increasing for the existence of negative social impacts such as stigmatization and/or discrimination, and ethically problematic practices, including lack of informed consent. We conclude that the relationship between the benefits and burdens of VMMC programs may be more unfavorable than what has been commonly suggested by proponents of global VMMC campaigns.

Reflections on the Social Determinants of the COVID-19 Vaccination Programme in Zimbabwe

Zimbabwe has not been spared by the coronavirus disease COVID-19 which has wreaked havoc throughout the world. The country is currently grappling with the pandemic against a background of multiple complex socio-economic conditions. Unfortunately, COVID-19 has escalated prevalent human rights concerns and challenges, including health disparities, poverty, child sexual abuse, access to education, and freedom of speech. Although vaccines are an important tool for reducing the incidence of life-threatening diseases, social determinants of health contribute to vaccine hesitancy. This paper is based on scoping literature review of various relevant materials on the social determinants of health that are inhibiting Zimbabwe's COVID-19 vaccination programme. This paper aims to contribute to the ongoing discourses on COVID-19. Four main themes are highlighted as social determinants of COVID-19 vaccination: (i) vaccination priority groups; (ii) vaccination hesitancy due to myths; (iii) social exclusion; and (iv) corruption. Findings are discussed in light of the implications to the right to health and other related rights. We recommend that governments of developing countries and stakeholders intensify myth-busting campaigns if vaccination programmes are to gain currency. We further call for the inclusion of priority groups such as persons with disabilities and the elderly on the vaccination priority list.

Perceptions of the COVID-19 pandemic: a qualitative study with South African adults

INTRODUCTION

In South Africa, public perceptions of the COVID-19 pandemic and risk mitigation measures remain mixed. To better understand health behaviours in the context of COVID-19, a qualitative study was conducted, which aimed to investigate perceptions relating to the COVID-19 pandemic among the South African adult population.

METHODS

Twelve online focus groups were conducted across the following age groups: 18-34, 35-54, 55 + years old (total n = 70) in December 2021. Diversity across socioeconomic status, geographical areas, and urban and rural settings was maximised, with an equal representation of men and women. Focus groups were conducted, and audio recorded using an online platform, transcribed verbatim and thematically analysed using MAXQDA.

RESULTS

There were mixed perceptions around the pandemic, however, the majority of participants appreciated government actions at the onset of the pandemic and as a result government trust was reported to have initially been high. Nevertheless, as the pandemic progressed, challenges relating to government communication around the pandemic, the inconsistent application of preventative measures by government, the use of soldiers to enforce preventative measures, the banning of alcohol and cigarettes, government corruption and the pervasiveness of social media were reported to have eroded government trust, negatively impacting the uptake of preventative measures. Economic and psychological impacts were experienced differently across income groups. Low-income earners, who already had pre-existing economic challenges reported increased psychological and financial strain. While the once cushioned middle class reported an increase in job insecurity accompanied by psychological challenges. High income earners did not report economic challenges but reported being affected psychologically. Though, low-income earners reported an appreciation of the government financial relief afforded to them middle income earners appeared to not have received adequate financial support.

CONCLUSION

With the existing mistrust of government, there is need for government to leverage existing trusted sources in communities to aid in the implementation of preventative measures. These findings support the development of context specific solutions to address challenges faced at different socioeconomic levels.

A Qualitative Study Exploring Motivators and Barriers to COVID-19 Vaccine Uptake among Adults in South Africa and Zimbabwe

While vaccines are a well-established method of controlling the spread of infectious diseases, vaccine hesitancy jeopardizes curbing the spread of COVID-19. Through the Vaccine Information Network (VIN), this study explored barriers and motivators to COVID-19 vaccine uptake. We conducted 18 focus group discussions with male and female community members, stratified by country, age group, and—for Zimbabwe only—by HIV status. Participants’ median age across both countries was 40 years (interquartile range of 22–40), and most (65.9%) were female. We conceptualized the key themes within the World Health Organization’s Strategic Advisory Group of Experts on Immunization (SAGE) 3C (convenience, confidence, complacency) vaccine hesitancy model. Barriers to vaccine uptake—lack of convenience, low confidence, and high complacency—included inaccessibility of vaccines and vaccination sites, vaccine safety and development concerns, and disbelief in COVID-19’s existence. Motivators to vaccine uptake—convenience, confidence, and low complacency—included accessibility of vaccination sites, user-friendly registration processes, trust in governments and vaccines, fear of dying from COVID-19, and knowing someone who had died from or become infected with COVID-19. Overall, vaccine hesitancy in South Africa and Zimbabwe was influenced by inconvenience, a lack of confidence, and high complacency around COVID-19 vaccines.

The Impact of COVID-19 Vaccines on Male Semen Parameters: A Retrospective Cohort Study

The emergence of SARS-CoV-2 and the subsequent COVID-19 pandemic necessitated the development of adequate vaccines. Despite vaccines being demonstrated to be safe and effective for preventing severe disease and death, vaccine hesitancy remains. Reasons include concerns over adverse effects on male fertility, which have not been widely investigated. Therefore, this study is aimed at determining the impact of COVID-19 vaccination on semen parameters in a retrospective cohort study of South African males undergoing fertility assessment. The patients for this study were adult men who have previously undergone routine semen analysis for fertility assessment at Androcryos Andrology Laboratory (Johannesburg, South Africa) between March 2021 and March 2022. They also received vaccination within 3 months following a semen analysis and underwent a second semen analysis any time post-COVID-19 vaccination. From 277 records analysed, 46 patients met the inclusion criteria, receiving the Pfizer-BioNTech (BNT162b1) (63%), Johnson and Johnson (JNJ-78436735/Ad26.COV2S) (34.8%), and the AstraZeneca (AZD1222) (2.2%) vaccines. Sperm concentration significantly increased postvaccination ( $P=0.0001$ ), with no significant changes in semen pH, volume, total sperm count, progressive motility, normal sperm morphology, or chromatin condensation. Results were not influenced by age, type of vaccine received, and the number of days following vaccination, as depicted by multiple regression analysis. In conclusion, there is no evidence of a negative impact of COVID-19 vaccination on male semen parameters, which is consistent with the emerging literature on COVID-19 vaccination and male fertility. COVID-19 vaccinations should not be dismissed based on fear of adverse effects on male fertility parameters.

Acceptance of COVID-19 vaccine among sub-Saharan Africans (SSA): a comparative study of residents and diasporan dwellers

BACKGROUND

The COVID-19 vaccines are being rolled out across all the sub-Saharan Africa (SSA) countries, with countries setting targets for achieving full vaccination rates. The aim of this study was to compare the uptake of, resistance and hesitancy to the COVID-19 vaccine between SSA locally residents and in the diasporan dwellers.

METHODS

This was a cross-sectional study conducted using a web and paper-based questionnaire to obtain relevant information on COVID-19 vaccine acceptance. The survey items included questions on demography, uptake and planned acceptance or non-acceptance of the COVID-19 vaccines among SSAs. Multinomial logistic regression was used to determine probabilities of outcomes for factors associated with COVID-19 vaccination resistance and hesitancy among SSA respondents residing within and outside Africa.

RESULTS

Uptake of COVID-19 vaccines varied among the local (14.2%) and diasporan (25.3%) dwellers. There were more locals (68.1%) who were resistant to COVID-19 vaccine. Participants' sex [adjusted relative risk (ARR) = 0.73, 95% CI: 0.58 - 0.93], education [primary/less: ARR = 0.22, CI:0.12 - 0.40, and bachelor's degree: ARR = 0.58, CI: 0.43 - 0.77]), occupation [ARR = 0.32, CI: 0.25-0.40] and working status [ARR = 1.40, CI: 1.06-1.84] were associated with COVID-19 vaccine resistance among locals. Similar proportion of local and diasporan dwellers (~ 18% each) were hesitant to COVID-19 vaccine, and this was higher among health care workers [ARR = 0.25, CI: 0.10 - 0.62 and ARR = 0.24, CI:0.18-0.32, diaspora and locals respectively]. After adjusting for the potential confounders, local residents aged 29-38 years [ARR = 1.89, CI: 1.26-2.84] and lived in East Africa [ARR = 4.64, CI: 1.84-11.70] were more likely to report vaccine hesitancy. Knowledge of COVID vaccines was associated with hesitancy among local and diasporan dwellers, but perception was associated with vaccine resistance [ARR = 0.86,CI: 0.82 - 0.90] and hesitancy [ARR = 0.85, CI: 0.80 - 0.90], only among the local residents.

CONCLUSIONS

Differences exist in the factors that influence COVID-19 vaccine acceptance between local SSA residents and thediasporan dwellers. Knowledge about COVID-19 vaccines affects the uptake, resistance, and hesitancy to the COVID-19 vaccine. Information campaigns focusing on the efficacy and safety of vaccines could lead to improved acceptance of COVID-19 vaccines.

Promoting COVID-19 Vaccine Acceptance through Community Engagement: An Ethnographic Study in Ghana

Introduction. To successfully manage COVID-19 and to meet the target of vaccinating 22.9 million people in Ghana, the government has adopted community engagement as one of the strategies. Yet, the Volta Region continues to record the lowest rate of vaccine acceptance in Ghana. This study explored how government institutions engaged communities on COVID-19 vaccine preparedness and acceptance in two administrative municipalities in Ghana. Methods. This qualitative study employed face-to-face in-depth interviews among thirty-six respondents comprising of government officials and community leaders and ten focus group discussions among 87 people made up of men and women most of whom were natives and some migrants in two administrative municipalities in Ghana. Data were collected from June to September 2021. Audio interviews were transcribed and uploaded to Nvivo 12 to support triangulation, coding, and thematic analysis. Ethical approval was obtained from the requisite authority, and all COVID-19 restrictions were observed. Results. Government institutions focused on informing communities of vaccines and vaccination with little input from the communities. The Ghana Health Service carried out the most extensive engagement because they had more decentralized institutions. Successful engagement activities resulted in vaccine acceptance among some community members. Challenges in community engagement included insufficient logistics and myths and misconceptions about vaccines, which accounted for some community members’ lack of trust in vaccines, resulting in their unwillingness to vaccinate. Government officials used innovative approaches such as comparing the safety of COVID-19 vaccines to vaccines designed for children under the age of five years to deal with misinformation. Conclusion. Government needs to provide more resources to institutions that are mandated to carry out engagement activities to enable them carry out their tasks. It is further recommended that government institutions should intensify community engagement in distant communities to support the country to meet the target.

Low coverage of COVID-19 vaccines in Africa: current evidence and the way forward

Disparities in COVID-19 vaccine coverage across the globe have uncovered inequities in global healthcare. While more than half of the population of the developed countries have been fully vaccinated, only a small percentage of the African population has received one vaccine dose so far, a far cry from the global vaccination targets. Furthermore, several low and middle income (LMICs) African countries lack the competence, infrastructure, logistics, and financial resources to mass-vaccinate their populations. This paper highlights the causes and implications of the low COVID-19 vaccine coverage on Africa and the global community, and discusses strategies for restructuring and strengthening COVID-19 vaccination in Africa.

Uptake of public health measures and vaccine acceptance during the COVID-19 pandemic in rural Zambia

Vaccines are effective tools to prevent COVID-19-related morbidity. However, coverage is low throughout sub-Saharan Africa. Uptake of public health measures, perceptions of COVID-19 illness and vaccines, and intention to vaccinate were evaluated in 2021-2022 in rural Zambia. Adherence to public health measures, perceptions of COVID-19 risk and severity, and vaccine acceptance increased significantly over time, particularly in December 2021, coinciding with the fourth pandemic wave and relaunch of the national vaccine campaign. Vaccine acceptance was associated with perceptions of vaccine safety and effectiveness, but not disease severity. These findings highlight the importance of strong pandemic response and public communication for increased uptake of mitigatory measures, including vaccine acceptance.

COVID-19 vaccine acceptance and its determinants in the Bono Region of Ghana

Objective

The study assessed willingness to accept the COVID-19 vaccine among out-patient department (OPD) attendants in the Bono Region in Ghana.

Design

This was an analytical cross-sectional study.

Setting

The study was conducted at the Wenchi Methodist Hospital (WMH) OPD, Bono Region, Ghana. The region had not yet been earmarked for vaccination at the time of the study.

Participants

Three hundred and twenty-five (325) participants aged ≥18 years, accessing care at the OPD of WMH and willing to give informed consent, were interviewed.

Main outcome measures

The proportion of participants willing to accept the COVID-19 vaccine and its determinants.

Results

Of 325 participants interviewed, 32 (9.8%) had been vaccinated already. 82.6% (242/293) indicated COVID-19 vaccine acceptance among the unvaccinated. The major reason for vaccine acceptance was "it could protect against COVID-19" (96.7%, 234/242). "Fear of vaccine side effects and "perception of not being susceptible to COVID-19" were among the reasons for vaccine refusal. Perceived susceptibility to COVID-19 (AOR 4.09, 95% CI 1.79, 9.34), knowledge of COVID-19 and COVID-19 vaccine (AOR 3.62, 95% CI 1.14, 11.46) and willingness to pay for the vaccine (AOR 5.20, 95% CI 2.49, 10.43) were associated with vaccine acceptance.

Conclusions

Adequate knowledge of COVID-19 and the vaccine may drive vaccine acceptance in the study area and possibly other areas in Ghana. Campaign messages aimed at increasing COVID-19 vaccine coverage must emphasise its safety, likely side effects and management in order to help rid the population of misconceptions.

Modeling COVID-19 infection in high-risk settings and low-risk settings

In this research paper we present a mathematical model for COVID-19 in high-risk settings and low-risk settings which might be infection dynamics between hotspots and less risky communities. The main idea was to couple the SIR model with alternating risk levels from the two different settings high and low-risk settings. Therefore, building from this model we partition the infected class into two categories, the symptomatic and the asymptomatic. Using this approach we simulated COVID-19 dynamics in low and high-risk settings with auto-switching risk settings. Again, the model was analyzed using both analytic methods and numerical methods. The results of this study suggest that switching risk levels in different settings plays a pivotal role in COVID-19 progression dynamics. Hence, population reaction time to adhere to preventative measures and interventions ought to be implemented with flash speed targeting first the high-risk setting while containing the dynamics in low-risk settings.

Challenges to COVID-19 vaccine introduction in the Democratic Republic of the Congo - a commentary

COVID-19 vaccination in the Democratic Republic of the Congo (DRC) began in April 2021. A month later, most COVID-19 vaccine doses were reallocated to other African countries, due to low vaccine uptake and the realization that the doses would expire before use. Based on data available on 13 August 2022, 2.76% of the DRC population had been fully vaccinated with last dose of primary series of COVID-19 vaccine, placing the country second to last in Africa and in the last five in global COVID-19 vaccination coverage. The DRC's reliance on vaccine donations requires continuous adaptation of the vaccine deployment plan to match incoming COVID-19 vaccines shipments. Challenges in planning vaccine deployments, vaccinating priority populations, coordinating, and implementing the communications plan, disbursing funds, and conducting supervision of vaccination activities have contributed to low COVID-19 vaccine coverage. In addition, the spread of rumors through social media and by various community and religious leaders resulted in high levels of vaccine hesitancy. A strong risk communication and community engagement plan, coupled with innovative efforts to target the highest-risk populations are critical to increase vaccine uptake during the next phase of COVID-19 vaccine introduction.

Get vaccinated or else…employees' perspective on mandatory vaccination in the retail sector in Zimbabwe

The emergence of COVID-19 has resulted in many changes in the world of work. Measures such as remote working, physical distancing, compulsory use of face masks, sanitization among others. With time, a number of medical interventions to deal with the pandemic were developed and availed. Zimbabwe's retail sector was not spared of different vaccines which were meant to curb the virus. Most Zimbabwean organizations made it mandatory for their employees to get vaccinated or risked losing employment. However, less is known about the perceptions of employees toward voluntary vaccination. This gap is important given the strategic nature of employees in an organization. This paper poses the following questions (1) to what extent were employees consulted on the compulsory vaccination? (2) What are the employees' perceptions toward compulsory vaccination? (3) How are employees coping with the mandatory vaccination? The study was premised on the classical work of Kurt Lewin on types of leadership, specifically autocratic-democratic styles. Twenty shopfloor employees from two major retail outlets with functional human resource departments and works councils in Masvingo were purposively sampled and interviewed using a semi-structured interview guide. The sample composed of women and men of different age groups. Thematic analysis was used to analyze data. The paper argues that employees have a right to be involved in issues that concern them. The study has established four levels of consultation existing on a continuum namely formal and genuine consultations, formal but less genuine consultations, informal consultations, and no consultation at all. The fourth level emerged to have been the most popular among most participants. With regards to employees' perceptions of mandatory vaccination by management, findings have revealed three categories which are, perceived good decision, perceived tight hands on the part of management and the them and us perceptions. Concerning reactions to mandatory vaccination, the study has shown that employees in the retail sector had a number of options to follow. Some went for full vaccination willingly or under duress, while others settled for a single dose. Most participants highlighted that they fraudulently obtained some vaccination cards. These findings support the relevance of engaging employees on matters that affect them. The study has therefore established the importance of genuine consultations between management and employees on issues that pertains the latter.

Determinants of COVID-19 vaccine hesitancy and uptake in sub-Saharan Africa: a scoping review

OBJECTIVE

To identify, describe and map the research tools used to measure COVID-19 vaccine hesitancy, refusal, acceptance and access in sub-Saharan Africa (SSA).

DESIGN

Scoping review.

METHODS

In March 2022, we searched PubMed, Scopus, Web of Science, Cochrane, Academic Search Premier, MEDLINE, Cumulative Index to Nursing and Allied Health Literature, Health Source Nursing, Africa Wide and APA PsychInfo for peer-reviewed literature in English related to COVID-19 vaccine hesitancy, refusal, acceptance and access in SSA. We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews to guide evidence gathering and as a template to present the evidence retrieval process.

RESULTS

In the studies selected for review (n=72), several measurement tools were used to measure COVID-19 vaccine hesitancy, acceptance and refusal. These measurements were willingness and intent to vaccinate from the perspectives of the general population, special population groups such as mothers, students and staff in academic institutions and healthcare workers and uptake as a proxy for measuring assumed COVID-19 vaccine acceptance. Measurements of access to COVID-19 vaccination were cost and affordability, convenience, distance and time to travel or time waiting for a vaccine and (dis)comfort. Although all studies measured COVID-19 vaccine hesitancy, acceptance and refusal, relatively few studies (n=16, 22.2%) included explicit measurements of access to COVID-19 vaccination.

CONCLUSIONS

Based on the gaps identified in the scoping review, we propose that future research on determinants of COVID-19 vaccination in SSA should further prioritise the inclusion of access-related variables. We recommend the development and use of standardised research tools that can operationalise, measure and disentangle the complex determinants of vaccine uptake in future studies throughout SSA and other low- and middle-income country (LMIC) settings.

Willingness to Accept COVID-19 Vaccine and Associated Factors Among Adult Household Members in Dire Dawa City Administration, East Ethiopia

Background

COVID-19 vaccine is a vital strategy to prevent and control this pandemic. This will depend principally on people's acceptance of COVID-19 vaccine. We aimed to determine the willingness to accept COVID vaccine among adult household members of Dire Dawa city administration.

Methods

A community-based cross-sectional study was conducted among randomly selected 634 adult household members in the Dire Dawa city administration during January 16-31/2022. Data were collected using face-to-face interview. Extent of willingness was estimated using participants' self-report. Bivariate and multivariate logistic regression models were fitted, and statistical significance was set at p-value <0.05.

Results

The estimated willingness to accept COVID-19 vaccine was 28.4% (95% CI 25.1, 31.5) in the study setting. The odds of willingness to accept COVID-19 vaccine was higher for household members living without at least one chronic disease (AOR 1.7, 95% CI 1.10, 2.70), who had good knowledge score (AOR 2.3, 95% CI 1.31, 2.18) and positive attitude score (AOR 5.5, 95% CI 2.1, 14.5) compared to their counterparts, respectively. The estimated willingness to accept COVID-19 vaccine among household members with good knowledge score was 47.4 (95% CI 42.1, 52.7) and 15.5 (95% CI 8.7, 22.2) among those with poor knowledge. Nearly, 90% of the study participants had limited knowledge about COVID 19 vaccine.

Conclusion

The estimated willingness to accept COVID-19 vaccine in the study setting is very low and far from the set target to be reached by the end of 2022. Being free from chronic disease, and having good knowledge and positive attitude about COVID-19 vaccine were the main drivers for willingness. Public awareness directed to increase knowledge about COVID-19 vaccine and attitude change strategies should be scaled up to increase the COVID-19 vaccine uptake. Moreover, those individuals with chronic diseases need special attention.

COVID-19 Vaccine Acceptance and Associated Factors among Women in Saudi Arabia: A Cross-Sectional Study

Although women have been substantially affected by the pandemic, they tend to have a lower likelihood of COVID-19 vaccine acceptance. Research on factors associated with COVID-19 vaccine acceptance among this key population is imperative. Thus, this study aimed to assess COVID-19 vaccine acceptance and associated factors among women in Saudi Arabia. This study was part of a larger study conducted on the acceptance of the COVID-19 vaccine in Saudi Arabia, carried out between the 8th and 14th of December 2020. The study sample included 910 women aged 18 years and older. Bivariate and multivariable regression analyses was utilized to analyze the data. Overall, 41% of the participants were willing to receive the vaccine. Participants were more willing to accept vaccination if they were 40–49 years old (OR = 2.209, 95% CI: 1.49–2.02), if they had a moderate (OR = 2.570, 95% CI 1.562–4.228) or high to very high (OR = 1.925, 95% CI 1.093–3.390) perceived likelihood of being infected with COVID-19, or if they were in favor of mandatory COVID-19 vaccination for people in Saudi Arabia (OR = 64.916, 95% CI 35.911–117.351). However, participants with a high educational level (OR = 0.431, 95% CI 0.220–0.847) or who refused physician-recommended vaccines in the past (OR = 0.152, 95% CI 0.083–0.275) were less likely to accept COVID-19 vaccination. Given the low level of vaccine acceptance among women, relevant stakeholders should consider the needs and dynamics of this key population to increase vaccination uptake and to improve current and future outreach activities.

Predictors of COVID-19 Vaccine Acceptance among Healthcare Workers in Nigeria

Healthcare workers (HCWs) are regarded as role models regarding health-related issues, including vaccination. Therefore, it is essential to identify the predictors for COVID-19 vaccine acceptance among them. A cross-sectional study to assess the risk perception, attitudes and knowledge of HCWs toward COVID-19 vaccination was carried out. A total of 710 responses were received between September 2021 and March 2022, from HCWs in the Northern, Western and Eastern regions of Nigeria. Cross tabulations were performed to determine statistical relations between sociodemographic variables, knowledge, attitudes and risk perceptions concerning COVID-19 vaccine acceptance. Multinomial logistic regression analysis was performed to determine the predictive variables for COVID-19 vaccine acceptance. Statistical analyses were performed and P-values less than 0.05 were considered statistically significant at a CI of 95%. Results showed that 59.3% of the participants were amenable to COVID-19 vaccines. Multinomial regression analysis identified 14 variables at α < 0.05 as predictors for vaccine acceptance. Male HCWs were 2.8 times more likely to accept the vaccine than their female counterparts. HCWs that were knowledgeable of the different kinds of vaccines, were willing to recommend the vaccines to their patients, believed that the timing of COVID-19 vaccination was appropriate and had recent vaccination history within three years were 1.6, 24.9, 4.4 and 3.1 times more likely to take COVID-19 vaccine than those not sure. The study found a relatively high trust (51.3%) in the Nigerian Center for Disease Control (NCDC) for information regarding COVID-19 vaccines. Therefore, the NDCD should disseminate more robust insights regarding the safety profiles of various COVID-19 vaccines.

Coronavirus Disease 2019 (COVID-19) Pandemic across Africa: Current Status of Vaccinations and Implications for the Future

The introduction of effective vaccines in December 2020 marked a significant step forward in the global response to COVID-19. Given concerns with access, acceptability, and hesitancy across Africa, there is a need to describe the current status of vaccine uptake in the continent. An exploratory study was undertaken to investigate these aspects, current challenges, and lessons learnt across Africa to provide future direction. Senior personnel across 14 African countries completed a self-administered questionnaire, with a descriptive analysis of the data. Vaccine roll-out commenced in March 2021 in most countries. COVID-19 vaccination coverage varied from low in Cameroon and Tanzania and up to 39.85% full coverage in Botswana at the end of 2021; that is, all doses advocated by initial protocols versus the total population, with rates increasing to 58.4% in Botswana by the end of June 2022. The greatest increase in people being fully vaccinated was observed in Uganda (20.4% increase), Botswana (18.5% increase), and Zambia (17.9% increase). Most vaccines were obtained through WHO-COVAX agreements. Initially, vaccination was prioritised for healthcare workers (HCWs), the elderly, adults with co-morbidities, and other at-risk groups, with countries now commencing vaccination among children and administering booster doses. Challenges included irregular supply and considerable hesitancy arising from misinformation fuelled by social media activities. Overall, there was fair to reasonable access to vaccination across countries, enhanced by government initiatives. Vaccine hesitancy must be addressed with context-specific interventions, including proactive programmes among HCWs, medical journalists, and the public.

Factors influencing the acceptability of COVID-19 vaccination: A cross-sectional study from Malaysia

Background

With the surge of COVID-19 cases worldwide, vaccines against COVID-19 are also developing across the countries. However, the acceptability of COVID-19 vaccination among general people is questionable. The availability of several vaccines’ options against COVID-19 has perplexed people regarding individual vaccines’ efficacy and safety. Therefore, we aim to determine the acceptance, preferences, impact factors of future COVID-19 vaccines in Malaysia and the factors influencing the COVID-19 vaccination acceptance among vaccine demand and vaccine delay groups.

Material and methods

An online-based cross-sectional survey was conducted among Malaysian residents 18 years and above of either gender using the snowball sampling technique. A self-administered questionnaire was made available to participants through various social media networks, email, and telegram. The data obtained from the survey were analyzed using SPSS version 25.0. Association between background characteristics and respondents were analyzed using the Chi-square test in the vaccine delay group and vaccine acceptance group.

Results

Total of 1282 responses were considered for the study, mainly from male respondents (71%). Among the respondents, 95.9% thought that vaccination would be an effective way to prevent and control COVID-19, and 96% would accept vaccination if the COVID-19 vaccine were successfully developed and approved for listing in the future. Essential factors influencing vaccination decisions were vaccine convenience (95.7%) and doctor's recommendation (97.3%). Bivariate analysis revealed that age less than 24 years, Malay race, living in urban areas, tertiary education, students, single marital status, family income (Malaysian ringgits) RM 4,850 to RM 10,959 and >RM 10,960 were significantly associated with vaccine acceptance of COVID19 vaccination.

Conclusion

All the factors influencing COVID-19 vaccine acceptance rates throughout the country should be studied on a larger scale, and appropriate steps to ensure vaccine acceptance among the public should be meticulously devised by the government and related authorities.

COVID-19 Vaccination, Morbidity, and Mortality During a 12-Month Period in Israel: Can We Maintain a "Herd Immunity" State?

Despite widespread vaccination, the COVID-19 pandemic continues to cause global disruption. Authors describe the pace of COVID-19 vaccination in Israel and examine differences in morbidity and mortality rates over time between vaccinated and unvaccinated populations. Retrospective data were obtained between December 2020 and December 2021 on daily vaccine uptake by age group (20-39, 40-59, 60+ years): rate of hospitalized severely ill cases, vaccination status and age group, and death rate per 100,000 by date and vaccination status. Uptake of first and second doses was slower in 20-59-year olds, whereas in 60+-year olds, it occurred without delay. Once most adults were vaccinated, a gap appeared with much higher severe cases and deaths in unvaccinated versus vaccinated populations; this gap attenuated by late May with very low rates in both vaccinated and unvaccinated populations until mid-July, when rates began to rise again. A herd-immunity-like period occurred in Spring 2021, with unvaccinated benefitting from a highly vaccinated population. Staggered vaccine uptake led to unsynchronized high immunity, which contributed to the fourth pandemic wave. Population vaccination within a shorter timeframe or shorter intervals between boosters may be important to reduce viral transmission.

Commentary on COVID-19 Vaccine Hesitancy in sub-Saharan Africa

Rates of vaccination against COVID-19 remain lower in sub-Saharan Africa than in other low and middle-income regions. This is, in part, attributed to vaccine hesitancy, mainly due to misinformation about vaccine origin, efficacy and safety. From August to December 2021, we gathered the latest experiences and opinions on four vaccine hesitancy-related areas (policies, perceived risk religious beliefs, and misinformation) from 12 sub-Saharan African researchers, four of whom have published about COVID-19 vaccine hesitancy. The authors included two political and business experts, six public health specialists, five epidemiologists, and four biostatisticians from ten sub-Saharan African countries( Cameroon, Ghana, Kenya, Liberia, Nigeria, Sierra Leone, South Africa, Tanzania, Uganda, and Zimbabwe). The authors’ overarching opinions were that political influences, religious beliefs and low perceived risk exists in sub-Saharan Africa, and they collectively contribute to COVID-19 vaccine hesitancy. Communication strategies should target populations initially thought by policy makers to be at low risk, use multiple communication avenues and address major concerns in the population.

Risk of mortality in HIV-infected COVID-19 patients: A systematic review and meta-analysis

BACKGROUND

The relationship between HIV infection and COVID-19 clinical outcomes remains a significant public health research problem. We aimed to determine the association of HIV comorbidity with COVID-19 mortality.

METHODS

We searched PubMed, Google Scholar and World Health Organization library databases for relevant studies. All searches were conducted from 1st to 7th December 2021. Title, abstract and full text screening was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The relative risk of mortality in HIV-infected COVID-19 patients was computed using a random-effects model. All analyses were performed using Meta and Metasens statistical packages available in R version 4.2.1 software package. The quality of included studies was assessed using the GRADE approach, Egger's test was employed to determine the risk of bias.

RESULTS

A total of 16 studies were included in this review. Among the COVID-19 patients with HIV infection, the mortality rate due to COVID-19 was 7.97% (4 287/53,801), and among the COVID-19 patients without HIV infection, the mortality rate due to COVID-19 was 0.69% (127, 961/18, 513, 747). In the random effects model, we found no statistically significant relative risk of mortality in HIV-infected COVID-19 patients (RR 1.07, 95% CI 0.86-1.32). The between-studies heterogeneity was substantial (I2 = 91%, P < 0.01), while the risk of publication bias was not significant.

CONCLUSION

Findings did not link HIV infection with an increased risk of COVID-19 mortality. Our results add to the conflicting data on the relationship between COVID-19 and HIV infection.

Virtual healthcare services and digital health technologies deployed during coronavirus disease 2019 (COVID-19) pandemic in South Africa: a systematic review

Aims

To identify virtual healthcare services and digital health technologies deployed in South Africa during coronavirus disease 2019 (COVID-19) and the challenges associated with their use.

Methods

To determine the status of digital health utilization during COVID-19 in South Africa, the preferred reporting items for systematic reviews and meta-analyses model was used to perform a systematic and in-depth critical analysis of previously published studies in well-known and trusted online electronic databases using specific search keywords words that are relevant to this study. We selected published peer-reviewed articles available from the onset of COVID-19 to July 2021.

Results

Total of 24 articles were included into this study. This study revealed that South Africa adopted digital technologies such as SMS-based solutions, mobile health applications, telemedicine and telehealth, WhatsApp-based systems, artificial intelligence and chatbots and robotics to provide healthcare services during COVID-19 pandemic. These innovative technologies have been used for various purposes including screening infectious and non-infectious diseases, disease surveillance and monitoring, medication and treatment compliance, creating awareness and communication. The study also revealed that teleconsultation and e-prescription, telelaboratory and telepharmacy, teleeducation and teletraining, teledermatology, teleradiology, telecardiology, teleophthalmology, teleneurology, telerehabilitation, teleoncology and telepsychiatry are among virtual healthcare services delivered through digital health technologies during COVID-19 in South Africa. However, these smart digital health technologies face several impediments such as infrastructural and technological barriers, organization and financial barriers, policy and regulatory barriers as well as cultural barriers.

Conclusion

Although COVID-19 has invigorated the use of digital health technologies, there are still some shortcomings. The outbreak of pandemics like COVID-19 in the future is not inevitable. Therefore, we recommend increasing community networks in rural areas to bridge the digital divide and the modification of mHealth policy to advocate for the effective use of innovative technologies in healthcare and the development of sustainable strategies for resources mobilization through private-public partnerships as well as joining available international initiatives advocating for smart digital health.

New Wave of COVID-19 Vaccine Opinions in the Month the 3rd Booster Dose Arrived

Vaccination has been proposed as one of the most effective methods to combat the COVID-19 pandemic. Since the day the first vaccine, with an efficiency of more than 90%, was announced, the entire vaccination process and its possible consequences in large populations have generated a series of discussions on social media. Whereas the opinions triggered by the administration of the initial COVID-19 vaccine doses have been discussed in depth in the scientific literature, the approval of the so-called 3rd booster dose has only been analyzed in country-specific studies, primarily using questionnaires. In this context, the present paper conducts a stance analysis using a transformer-based deep learning model on a dataset containing 3,841,594 tweets in English collected between 12 July 2021 and 11 August 2021 (the month in which the 3rd dose arrived) and compares the opinions (in favor, neutral and against) with the ones extracted at the beginning of the vaccination process. In terms of COVID-19 vaccination hesitance, an analysis based on hashtags, n-grams and latent Dirichlet allocation is performed that highlights the main reasons behind the reluctance to vaccinate. The proposed approach can be useful in the context of the campaigns related to COVID-19 vaccination as it provides insights related to the public opinion and can be useful in creating communication messages to support the vaccination campaign.

COVID-19 Vaccine Acceptance Rate and Its Factors among Healthcare Students: A Systematic Review with Meta-Analysis

Healthcare students are clinicians-in-training likely to come into contact with COVID-19 as much as other frontline healthcare professionals. It is therefore necessary to prioritize vaccinations for this group. We conducted a global systematic assessment of COVID-19 vaccine acceptance rates and related factors among healthcare students using the PubMed, Scopus, and Web of Science databases and keyword searches in March of 2022. We found 1779 articles with relevant information and 31 articles that matched our inclusion criteria. We performed a random-effects meta-analysis and quality assessment using the eight-item Joanna Briggs Institute Critical Appraisal test for cross-sectional studies. A total of 30,272 individuals from 16 countries were studied. Most of the studies were carried out in the U.S. (n = 6), China (n = 5), Poland (n = 5), India (n = 2), Italy (n = 2), and Israel (n = 2). The prevalence of the COVID-19 vaccine acceptance rate was 68.8% (95% confidence interval [CI]: 60.8-76.3, I2 = 100%), and the prevalence of the vaccine hesitancy rate was 25.8% (95% CI: 18.5-33.8, I2 = 99%). In country-specific analyses, Romania showed the highest acceptance rate (88.0%, 95% CI: 44.5-100%), while Iraq showed the lowest acceptance rate (66.2%, 95% CI: 35.5-90.8%). In time-trend analyses, we found that acceptance rates among healthcare students decreased over time. Students concerned about potentially serious side effects of the vaccine were less willing to accept the vaccine. National and international interventions should be adopted to reduce COVID-19 vaccination hesitancy rates among these important frontline workers.

Unmet need for COVID-19 vaccination coverage in Kenya

COVID-19 has impacted the health and livelihoods of billions of people since it emerged in 2019. Vaccination for COVID-19 is a critical intervention that is being rolled out globally to end the pandemic. Understanding the spatial inequalities in vaccination coverage and access to vaccination centres is important for planning this intervention nationally. Here, COVID-19 vaccination data, representing the number of people given at least one dose of vaccine, a list of the approved vaccination sites, population data and ancillary GIS data were used to assess vaccination coverage, using Kenya as an example. Firstly, physical access was modelled using travel time to estimate the proportion of population within 1 hour of a vaccination site. Secondly, a Bayesian conditional autoregressive (CAR) model was used to estimate the COVID-19 vaccination coverage and the same framework used to forecast coverage rates for the first quarter of 2022. Nationally, the average travel time to a designated COVID-19 vaccination site (n = 622) was 75.5 min (Range: 62.9 - 94.5 min) and over 87% of the population >18 years reside within 1 hour to a vaccination site. The COVID-19 vaccination coverage in December 2021 was 16.70% (95% CI: 16.66 - 16.74) - 4.4 million people and was forecasted to be 30.75% (95% CI: 25.04 - 36.96) - 8.1 million people by the end of March 2022. Approximately 21 million adults were still unvaccinated in December 2021 and, in the absence of accelerated vaccine uptake, over 17.2 million adults may not be vaccinated by end March 2022 nationally. Our results highlight geographic inequalities at sub-national level and are important in targeting and improving vaccination coverage in hard-to-reach populations. Similar mapping efforts could help other countries identify and increase vaccination coverage for such populations.

Maternal, Sexual and Reproductive Health in Marginalised Areas: Renewing Community Involvement Strategies beyond the Worst of the COVID-19 Pandemic

The COVID-19 pandemic and resultant lockdowns have brought unprecedented challenges for Maternal, Sexual and Reproductive Health (MSRH) services. Components of MSRH services adversely affected include antenatal, postnatal, and newborn care; provision of family planning and post-abortion care services; sexual and gender-based violence care and prevention; and care and treatment for sexually transmitted infections including HIV. Resuscitating, remodeling or inventing interventions to restore or maintain these essential services at the community level, as a gateway to higher care, is critical to mitigating short and long-term effects of the COVID-19 pandemic on essential MSRH. We propose a possible framework for community involvement and propose integrating key information, education, and communication of MSRH messages within COVID-19 messages.

COVID-19 Vaccine Acceptance among Low- and Lower-Middle-Income Countries: A Rapid Systematic Review and Meta-Analysis

Widespread vaccination against COVID-19 is critical for controlling the pandemic. Despite the development of safe and efficacious vaccinations, low-and lower-middle income countries (LMICs) continue to encounter barriers to care owing to inequitable access and vaccine apprehension. This study aimed to summarize the available data on COVID-19 vaccine acceptance rates and factors associated with acceptance in LMICs. A comprehensive search was performed in PubMed, Scopus, and Web of Science from inception through August 2021. Quality assessments of the included studies were carried out using the eight-item Joanna Briggs Institute Critical Appraisal tool for cross-sectional studies. We performed a meta-analysis to estimate pooled acceptance rates with 95% confidence intervals (CI). A total of 36 studies met the inclusion criteria and were included in the review. A total of 83,867 respondents from 33 countries were studied. Most of the studies were conducted in India (n = 9), Egypt (n = 6), Bangladesh (n = 4), or Nigeria (n = 4). The pooled-effect size of the COVID-19 vaccine acceptance rate was 58.5% (95% CI: 46.9, 69.7, I2 = 100%, 33 studies) and the pooled vaccine hesitancy rate was 38.2% (95% CI: 27.2-49.7, I2 = 100%, 32 studies). In country-specific sub-group analyses, India showed the highest rates of vaccine acceptancy (76.7%, 95% CI: 65.8-84.9%, I2= 98%), while Egypt showed the lowest rates of vaccine acceptancy (42.6%, 95% CI: 16.6-73.5%, I2= 98%). Being male and perceiving risk of COVID-19 infection were predictors for willingness to accept the vaccine. Increasing vaccine acceptance rates in the global south should be prioritized to advance global vaccination coverage.

COVID-19 pandemic waves: how prepared is West Africa for managing a high COVID-19 caseload? Urgent actions needed

The ECOWAS Region and the world have learnt a lot in the last year and a half concerning the pandemic. As the pandemic continues to evolve, the region needs to put together all these lessons in other to better protect its people, rebuild its economy and strengthen the regional health security for better regional prosperity. We reviewed the response mounted by the region from January 2020 to July 2021 and the existing body of knowledge. We recommend that the region quickly increase the COVID-19 immunization coverage, sustain the enhance genomic surveillance, improve testing and the strengthen point of entry surveillance.

Longitudinal changes in COVID-19 vaccination intent among South African adults: evidence from the NIDS-CRAM panel survey, February to May 2021

Background

COVID-19 vaccine hesitancy has threatened the ability of many countries worldwide to contain the pandemic. Given the severe impact of the pandemic in South Africa and disruptions to the roll-out of the vaccine in early 2021, slower-than-expected uptake is a pressing public health challenge in the country. We examined longitudinal changes in COVID-19 vaccination intent among South African adults, as well as determinants of intent to receive a vaccine.

Methods

We used longitudinal data from Wave 4 (February/March 2021) and Wave 5 (April/May 2021) of the National Income Dynamics Study: Coronavirus Rapid Mobile Survey (NIDS-CRAM), a national and broadly representative panel survey of adults in South Africa. We conducted cross-sectional analyses on aggregate and between-group variation in vaccination intent, examined individual-level changes between waves, and modeled demographic predictors of intent.

Results

We analysed data for 5629 (Wave 4; 48% male, mean age 41.5 years) and 5862 (Wave 5; 48% male, mean age 41.6 years) respondents. Willingness to get a COVID-19 vaccine significantly increased from 70.8% (95% CI: 68.5–73.1) in Wave 4 to 76.1% (95% CI: 74.2–77.8) in Wave 5. Individual-level analyses indicated that only 6.6% of respondents remained strongly hesitant between survey waves. Although respondents aged 18–24 years were 8.5 percentage points more likely to report hesitancy, hesitant respondents in this group were 5.6 percentage points more likely to change their minds by Wave 5. Concerns about rushed testing and safety of the vaccines were frequent and strongly-held reasons for hesitancy.

Conclusions

Willingness to receive a COVID-19 vaccine has increased among adults in South Africa, and those who were entrenched in their reluctance make up a small proportion of the country’s population. Younger adults, those in formal housing, and those who trusted COVID-19 information on social media were more likely to be hesitant. Given that stated vaccination intent may not translate into behaviour, our finding that three-quarters of the population were willing to accept the vaccine may reflect an upper bound. Vaccination promotion campaigns should continue to frame vaccine acceptance as the norm and tailor strategies to different demographic groups.

A Battle against COVID-19: Vaccine Hesitancy and Awareness with a Comparative Study between Sinopharm and AstraZeneca

Background: Awareness about the COVID-19 vaccine’s adverse effects is crucial for gaining public trust. As we still lack proof of vaccines’ safety, this survey aimed to investigate Egyptians’ general awareness of the Sinopharm and AstraZeneca vaccines against COVID-19 and provide considerable evidence on their side effects and complications. Methods: A cross-sectional questionnaire-based study was conducted in Egypt between 20 September and 10 October in 2021, with multiple-choice questions (MCQs) covering all data on vaccine administration confusion, adverse effects or intensity, and complications. Results: Among the 390 participants, 42.3% reported being hesitant before receiving one of the vaccines. About 40.3% of participants were previously infected before getting vaccinated while only 4.6% reported being infected after vaccination. The AstraZeneca vaccine demonstrated higher side effects and symptoms than the Sinopharm vaccine while the Sinopharm vaccine showed a significantly higher rate of COVID-19 infection after vaccination. Conclusions: People with higher educational levels and chronic respiratory diseases represent an excellent model for accepting COVID-19 vaccination. A booster shot is recommended for people vaccinated with the Sinopharm vaccine due to a significantly higher rate of COVID-19 infection after vaccination; however, the Sinopharm vaccine shows a more acceptable safety profile.

Inappropriate Antibiotic Use in Zimbabwe in the COVID-19 Era: A Perfect Recipe for Antimicrobial Resistance

The global COVID-19 pandemic has resulted in an upsurge in antimicrobial use. The increase in use is multifactorial, and is particularly related to the empirical treatment of SARS-CoV-2 and suspected coinfections with antimicrobials and the limited quality of diagnostics to differentiate viral and bacterial pneumonia. The lack of clear clinical guidelines across a wide range of settings, and the inadequacy of public health sectors in many countries, have contributed to this pattern. The increased use of antimicrobials has the potential to increase incidences of antimicrobial resistance, especially in low-resource countries such as Zimbabwe already grappling with multidrug-resistant micro-organism strains. By adopting the antimicrobial stewardship principles of the correct prescription and optimised use of antimicrobials, as well as diagnostic stewardship, revamping regulatory oversight of antimicrobial surveillance may help limit the occurrence of antimicrobial resistance during this pandemic.

The Landscape of COVID-19 Vaccination in Zimbabwe: A Narrative Review and Analysis of the Strengths, Weaknesses, Opportunities and Threats of the Programme

The ongoing COVID-19 pandemic brought unprecedented challenges for the population. The advent of national COVID-19 vaccination programmes was therefore welcome as a key control strategy for the COVID-19 pandemic, as evidence has shown that vaccination is the best strategy to reduce the adverse individual and population level adverse outcomes associated with infectious diseases such as COVID-19. Zimbabwe rolled out its vaccination programme in February 2021 with an ambitious target to vaccinate at least 60% of its eligible population by December 2021. However, by that time, the country was still to reach that target. To move the vaccination programme towards achieving this target, it is crucial to understand the strengths, weaknesses, opportunities and threats to the programme. We, therefore, with this narrative review, discuss some of the strengths, weaknesses, opportunities and threats to the programme since its rollout in February 2021. Though the programme has several strengths and opportunities to leverage on, we argue that among other challenges, the emergence of new variants of concern poses one of the biggest threats to local, regional and international vaccination programmes and requires concerted multistakeholder efforts to deal with. Additionally, addressing vaccine hesitancy remains as important as availing the vaccines to the population, to obtain the most benefits out of the programme.

Scientific Evidence Supporting Coronavirus Disease 2019 (COVID-19) Vaccine Efficacy and Safety in People Planning to Conceive or Who Are Pregnant or Lactating

Three coronavirus disease 2019 (COVID-19) vaccines have been authorized for use in the United States; specifically, the Pfizer-BioNTech, Moderna, and Johnson & Johnson-Janssen COVID-19 vaccines were granted emergency use authorization by the U.S. Food and Drug Administration in late 2020 and early 2021. Vaccination coverage and intent among adults are lowest among those aged 18-39 years and among females in particular. In females of reproductive age, enthusiasm for receiving a COVID-19 vaccine may be negatively affected by claims currently circulating widely on diverse social media platforms regarding the vaccines adversely affecting fertility and pregnancy. Yet it is important to note that these claims are anecdotal in nature and not supported by the available scientific evidence. It is also imperative that the effects of COVID-19 vaccine on reproductive health are clarified. Herein, we discuss the existing scientific data supporting COVID-19 vaccine safety and efficacy in people who are planning to conceive or who are pregnant or lactating and highlight the importance of COVID-19 vaccination in females of reproductive age.

COVID-19 vaccine hesitancy: Vaccination intention and attitudes of community health volunteers in Kenya

In Kenya, community health volunteers link the formal healthcare system to urban and rural communities and advocate for and deliver healthcare interventions to community members. Therefore, understanding their views towards COVID-19 vaccination is critical to the country's successful rollout of mass vaccination. The study aimed to determine vaccination intention and attitudes of community health volunteers and their potential effects on national COVID-19 vaccination rollout in Kenya. This cross-sectional study involved community health volunteers in four counties: Mombasa, Nairobi, Kajiado, and Trans-Nzoia, representing two urban and two rural counties, respectively. COVID-19 vaccination intention among community health volunteers was 81% (95% CI: 0.76-0.85). On individual binary logistic regression level, contextual influence: trust in vaccine manufacturers (adjOR = 2.25, 95% CI: 1.06-4.59; p = 0.030); individual and group influences: trust in the MoH (adjOR = 2.12, 90% CI: 0.92-4.78; p = 0.073); belief in COVID-19 vaccine safety (adjOR = 3.20, 99% CI: 1.56-6.49; p = 0.002), and vaccine safety and issues: risk management by the government (adjOR = 2.46, 99% CI: 1.32-4.56; p = 0.005) and vaccine concerns (adjOR = 0.81, 90% CI: 0.64-1.01; p = 0.064), were significantly associated with vaccination intention. Overall, belief in COVID-19 vaccine safety (adjOR = 2.04, 90% CI: 0.92-4.47 p = 0.076) and risk management by the government (adjOR = 1.86, 90% CI: 0.94-3.65; p = 0.072) were significantly associated with vaccination intention. Overall vaccine hesitancy among community health volunteers in four counties in Kenya was 19% (95% CI: 0.15-0.24), ranging from 10.2-44.6% across the counties. These pockets of higher hesitancy are likely to negatively impact national vaccine rollout and future COVID-19 vaccination campaigns. The determinants of hesitancy arise from contextual, individual and group, and vaccine or vaccination specific concerns, and vary from county to county.
