Addressing challenges to rolling out COVID-19 vaccines in African countries

Vaccine inequity: a threat to Africa's recovery from COVID-19

BACKGROUND

Vaccine inequity is a reality facing the Sub-Saharan Africa region as vaccine nationalism from high-income countries (HICs) leads to limited access to the lifesaving vaccines needed to end the pandemic. In Africa, a significant portion of the population has yet to be vaccinated against Covid-19; however, the barriers to accessing such vaccines, including capacity challenges, still persist despite the implementation of the COVAX facility meant to support the lower- and middle-income countries (LMICs) to boost vaccination.

METHODS

This study involved a systemic narrative review where literature search was conducted using the NCBI's PMC and BMC databases based on defined keywords. Three authors were involved in the literature search and consensus was applied to settle disagreements and validate the findings.

RESULTS

In this systematic narrative review, we report that vaccine nationalism remains a challenge for LMICs as HICs still hoard vaccines and even bypass COVAX to procure doses directly from the manufacturers. Factors that promote vaccine hesitancy in Africa include misinformation regarding the Covid-19 vaccine, a lack of trust in politicians and the pharmaceutical industry, and concerns about vaccine safety and efficacy. The policies implemented to enhance vaccine coverage in Africa, such as mandates, community engagement, and partnerships, all seek to promote equity of vaccination and ending Covid-19.

CONCLUSION

Covid-19 vaccine inequity persists and contributes to prolonged pandemic in LMICs. In response, African governments have taken certain measures to enhance vaccine uptake but more needs to be done to address resistance to vaccines.

In vitro generated antibodies guide thermostable ADDomer nanoparticle design for nasal vaccination and passive immunization against SARS-CoV-2

Background

Due to COVID-19, pandemic preparedness emerges as a key imperative, necessitating new approaches to accelerate development of reagents against infectious pathogens.

Methods

Here, we developed an integrated approach combining synthetic, computational and structural methods with in vitro antibody selection and in vivo immunization to design, produce and validate nature-inspired nanoparticle-based reagents against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Results

Our approach resulted in two innovations: (i) a thermostable nasal vaccine called ADDoCoV, displaying multiple copies of a SARS-CoV-2 receptor binding motif derived epitope and (ii) a multivalent nanoparticle superbinder, called Gigabody, against SARS-CoV-2 including immune-evasive variants of concern (VOCs). In vitro generated neutralizing nanobodies and electron cryo-microscopy established authenticity and accessibility of epitopes displayed by ADDoCoV. Gigabody comprising multimerized nanobodies prevented SARS-CoV-2 virion attachment with picomolar EC50. Vaccinating mice resulted in antibodies cross-reacting with VOCs including Delta and Omicron.

Conclusion

Our study elucidates Adenovirus-derived dodecamer (ADDomer)-based nanoparticles for use in active and passive immunization and provides a blueprint for crafting reagents to combat respiratory viral infections.

Assessing COVID-19 vaccine hesitancy and barriers to uptake in Sub-Saharan Africa

BACKGROUND

Despite improved availability of COVID-19 vaccines in Sub-Saharan Africa, vaccination campaigns in the region have struggled to pick up pace and trail the rest of the world. Yet, a successful vaccination campaign in Sub-Saharan Africa will be critical to containing COVID-19 globally.

METHODS

Here, we present new descriptive evidence on vaccine hesitancy, uptake, last-mile delivery barriers, and potential strategies to reach those who remain unvaccinated. Our data comes from national high frequency phone surveys in six countries in East and West Africa with a total population of 415 million people. Samples were drawn from nationally representative samples of households interviewed in recent in-person surveys. Our estimates are based on a survey module harmonized across countries and are re-weighted to mitigate potential sample selection biases.

RESULTS

We show that vaccine acceptance remains generally high among respondents in Sub-Saharan Africa (between 95.1% and 63.3%) even though hesitancy is non-negligible among those pending vaccination. Many who are willing to get vaccinated are deterred by a lack of easy access to vaccines at the local level. Furthermore, social ties and perceptions as well as intra-household power relations matter for vaccine take-up. Among the unvaccinated population, radio broadcasts have widespread reach and medical professionals are highly trusted.

CONCLUSIONS

Our findings highlight that creating a positive social norm around COVID-19 vaccination, messaging that leverages trusted and accessible information sources and channels, and more easily accessible vaccination sites at the community level are promising policy options to boost vaccination campaigns in the region and end the pandemic everywhere.

Africa (COVID-19) Vaccine Technology Transfer: Where Are We?

The rampant spread of the COVID-19 infection poses a grave and formidable challenge to global healthcare, with particular concern to the inhabitants of the African continent. In response to these pressing concerns, different strategies have been employed to combat the emergence of this insidious disease, encompassing crucial measures such as physical distancing, the utilization of face masks, meticulous hand hygiene, and widespread vaccination campaigns. Nevertheless, the economic realities faced by numerous African nations, characterized by their classification as "low-income countries (LICs)", present a formidable barrier to accessing and distributing approved vaccines to their populations. Moreover, it is essential to discuss the hesitancy of the European Union (EU) in releasing intellectual property rights associated with the transfer of vaccine technology to Africa. While the EU has been a key player in global efforts to combat the pandemic, there has been reluctance in sharing valuable knowledge and resources with African countries. This hesitancy raises concerns about equitable vaccine access and the potential for a prolonged health crisis in Africa. This review underscores the urgent imperative and need of establishing localized vaccine development and production facilities within Africa, necessitating the active involvement of governments and collaborative partnerships to achieve this crucial objective. Furthermore, this review advocates for the exploration of viable avenues for the transfer of vaccine technology as a means to facilitate equitable vaccine access across the African continent and also the cruciality and the need for the EU to reconsider its stance and actively engage in transferring vaccine technology to Africa through sharing intellectual property. The EU can contribute to the establishment of localized vaccine production facilities on the continent, which will not only increase vaccine availability but also promote self-sufficiency and resilience in the face of future health emergencies.

Antibiotic resistance and the COVID-19 pandemic: A dual crisis with complex challenges in LMICs

Background and Aims

Antimicrobial resistance (AMR), a global health crisis of mounting urgency, has been further complicated by the ongoing COVID-19 pandemic. The intricate relationship between these two phenomena is especially pronounced in low- and middle-income countries (LMICs) due to the distinct obstacles encountered by their healthcare systems and policy structures. This study aims to explore the complex challenges arising from the coexistence of these two crises in LMICs and proffer specific recommendations for holistic management.

Methods

An exhaustive bibliographic survey was executed, employing search queries in specialized databases such as PubMed, SCOPUS, and Web of Science's SCI-EXPANDED index. The timeframe for the literature search extended from January 2020 to January 2023. The search strategy employed key terms including antibiotic resistance, AMR, COVID-19 pandemic, low- and middle-income countries, SARS-CoV-2, and LMICs.

Results

The pandemic has aggravated various drivers of AMR in LMICs, including limited capabilities, weak frameworks, and socioeconomic factors. New challenges have emerged, such as disruptions in the antibiotic supply chain and an increased risk of healthcare-associated infections. The interaction between these drivers presents a complex problem that demands a coordinated response. Specific recommendations include strengthening health systems, funding research and innovation, and enhancing infection prevention control measures.

Conclusion

The coexistence of AMR and the COVID-19 pandemic in LMICs demands an integrated approach involving multiple stakeholders. Emphasis must be placed on constructing aligned regulatory frameworks, nurturing regional collaborations, and focusing on accessible therapeutic options. The study underscores the necessity for actionable strategies to achieve sustainable access to clean water and sanitation and also highlights the importance of long-term planning, funding, and specialized expertise in emerging modalities like phage therapy.

Prioritizing COVID-19 vaccine allocation in resource poor settings: Towards an Artificial Intelligence-enabled and Geospatial-assisted decision support framework

OBJECTIVES

To propose a novel framework for COVID-19 vaccine allocation based on three components of Vulnerability, Vaccination, and Values (3Vs).

METHODS

A combination of geospatial data analysis and artificial intelligence methods for evaluating vulnerability factors at the local level and allocate vaccines according to a dynamic mechanism for updating vulnerability and vaccine uptake.

RESULTS

A novel approach is introduced including (I) Vulnerability data collection (including country-specific data on demographic, socioeconomic, epidemiological, healthcare, and environmental factors), (II) Vaccination prioritization through estimation of a unique Vulnerability Index composed of a range of factors selected and weighed through an Artificial Intelligence (AI-enabled) expert elicitation survey and scientific literature screening, and (III) Values consideration by identification of the most effective GIS-assisted allocation of vaccines at the local level, considering context-specific constraints and objectives.

CONCLUSIONS

We showcase the performance of the 3Vs strategy by comparing it to the actual vaccination rollout in Kenya. We show that under the current strategy, socially vulnerable individuals comprise only 45% of all vaccinated people in Kenya while if the 3Vs strategy was implemented, this group would be the first to receive vaccines.

Measuring behavioral and social drivers of COVID-19 vaccination in health workers in Eastern and Southern Africa

BACKGROUND

In 2021, twenty out of twenty-one countries in the Eastern and Southern Africa (ESA) region introduced COVID-19 vaccines. With variable willingness to uptake vaccines across countries, the aim of the present study was to better understand factors that impact behavioral and social drivers of vaccination (BeSD). Using the theory-based "increasing vaccination model", the drivers Thinking & Feeling, Social Processes, Motivation, and Practical Issues were adapted to the COVID-19 context and utilized in a cross-country assessment.

METHODS

Data was collected on 27.240 health workers in Kenya, Malawi, Mozambique, South Africa and South Sudan. This was done by administering a survey of seven target questions via the UNICEF Internet of Good Things (IoGT) online platform between February and August 2021.

RESULTS

Findings showed a gap between perceived importance and trust in vaccines: Most health workers thought Covid-19 vaccination was very important for their health, while less than 30% trusted it very much. The pro-vaccination social and work norm was not well established since almost 66% of all respondents would take the vaccine if recommended to them, but only 49% thought most adults would, and only 48% thought their co-workers would. Access was highlighted as a crucial barrier, with less than a quarter reporting that accessing vaccination services for themselves would be very easy. Women exhibited slightly lower scores than men across the board. When testing the associations between drivers in Kenya and South Africa, it appears that when target interventions are developed for specific age groups, social norms become the main drivers of intention to get vaccinated.

CONCLUSIONS

The present study revealed various key relations with demographic variables that would help immunization programmes and implementing partners to develop targeted interventions. First, there is a serious gap between perceived importance of COVID-19 vaccines and how much trust people in them. Second, problems with access are still rather serious and solving this would strongly benefit those who demand a vaccine, Third, the role of social norms is the most important predictor of willingness when considering age differences.

The evolution of COVID-19 vaccine hesitancy in Sub-Saharan Africa: evidence from panel survey data

BACKGROUND

COVID-19 vaccination efforts are lagging in Sub-Saharan Africa, as just over 20 percent of the population has been fully vaccinated. COVID-19 vaccine hesitancy is considered important as a prerequisite for widespread vaccine take-up. Here, we study the dynamics of vaccine acceptance, its correlates, and reasons for hesitancy over time, drawing on two years of panel survey data.

METHODS

In this observational study, we use multiple rounds of data from national High Frequency Phone Surveys (HFPS) in five countries in East and West Africa (Burkina Faso, Ethiopia, Malawi, Nigeria, and Uganda), covering a period between 2020 and 2022. The surveys are cross-country comparable and draw their samples from nationally representative sampling frames. Based on this data source, the study presents population-weighted means and performs multivariate regression analysis.

RESULTS

COVID-19 vaccine acceptance was high throughout the study period (68% to 98%). However, acceptance levels were lower in 2022 than in 2020 in three countries (Burkina Faso, Malawi, Nigeria), and higher in one country (Uganda). Moreover, individuals are observed to change their stated vaccine attitudes between survey rounds, to a limited extent in some countries (Ethiopia) and more frequently in others (Burkina Faso, Malawi, Nigeria, Uganda). Vaccine hesitancy is higher in richer households, and those residing in urban areas; among women and those better educated. Hesitancy is lower in larger households and among heads of the household. The main reasons for hesitancy are concerns about side effects of the vaccine, its safety and efficacy, as well as assessments of COVID-19 risk, though these reasons fluctuate over time.

CONCLUSIONS

Reported COVID-19 vaccine acceptance levels remain far above vaccination rates in the study countries, suggesting that vaccine hesitancy is not the primary obstacle to reaching greater vaccine coverage, which may instead be related to access and delivery barriers as well as supply shortages. Nevertheless, vaccine attitudes appear malleable so that continued efforts are needed to retain high levels of vaccine acceptance.

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.

Understanding the challenges to COVID-19 vaccines and treatment options, herd immunity and probability of reinfection

Unlike pandemics in the past, the outbreak of coronavirus disease 2019 (COVID-19), which rapidly spread worldwide, was met with a different approach to control and measures implemented across affected countries. The lack of understanding of the fundamental nature of the outbreak continues to make COVID-19 challenging to manage for both healthcare practitioners and the scientific community. Challenges to vaccine development and evaluation, current therapeutic options, convalescent plasma therapy, herd immunity, and the emergence of reinfection and new variants remain the major obstacles to combating COVID-19. This review discusses these challenges in the management of COVID-19 at length and highlights the mechanisms needed to provide better understanding of this pandemic.

COVID-19 Vaccine Perceptions among Ebola-Affected Communities in North Kivu, Democratic Republic of the Congo, 2021

Populations affected by humanitarian crises and emerging infectious disease outbreaks may have unique concerns and experiences that influence their perceptions toward vaccines. In March 2021, we conducted a survey to examine the perceptions toward COVID-19 vaccines and identify the factors associated with vaccine intention among 631 community members (CMs) and 438 healthcare workers (HCWs) affected by the 2018-2020 Ebola Virus Disease outbreak in North Kivu, Democratic Republic of the Congo. A multivariable logistic regression was used to identify correlates of vaccine intention. Most HCWs (81.7%) and 53.6% of CMs felt at risk of contracting COVID-19; however, vaccine intention was low (27.6% CMs; 39.7% HCWs). In both groups, the perceived risk of contracting COVID-19, general vaccine confidence, and male sex were associated with the intention to get vaccinated, with security concerns preventing vaccine access being negatively associated. Among CMs, getting the Ebola vaccine was associated with the intention to get vaccinated (RR 1.43, 95% CI 1.05-1.94). Among HCWs, concerns about new vaccines' safety and side effects (OR 0.72, 95% CI 0.57-0.91), religion's influence on health decisions (OR 0.45, 95% CI 0.34-0.61), security concerns (OR 0.52, 95% CI 0.37-0.74), and governmental distrust (OR 0.50, 95% CI 0.35-0.70) were negatively associated with vaccine perceptions. Enhanced community engagement and communication that address this population's concerns could help improve vaccine perceptions and vaccination decisions. These findings could facilitate the success of vaccine campaigns in North Kivu and similar settings.

Assessing the Impact of Vaccination on the Dynamics of COVID-19 in Africa: A Mathematical Modeling Study

Several effective COVID-19 vaccines are administered to combat the COVID-19 pandemic globally. In most African countries, there is a comparatively limited deployment of vaccination programs. In this work, we develop a mathematical compartmental model to assess the impact of vaccination programs on curtailing the burden of COVID-19 in eight African countries considering SARS-CoV-2 cumulative case data for each country for the third wave of the COVID-19 pandemic. The model stratifies the total population into two subgroups based on individual vaccination status. We use the detection and death rates ratios between vaccinated and unvaccinated individuals to quantify the vaccine's effectiveness in reducing new COVID-19 infections and death, respectively. Additionally, we perform a numerical sensitivity analysis to assess the combined impact of vaccination and reduction in the SARS-CoV-2 transmission due to control measures on the control reproduction number (Rc). Our results reveal that on average, at least 60% of the population in each considered African country should be vaccinated to curtail the pandemic (lower the Rc below one). Moreover, lower values of Rc are possible even when there is a low (10%) or moderate (30%) reduction in the SARS-CoV-2 transmission rate due to NPIs. Combining vaccination programs with various levels of reduction in the transmission rate due to NPI aids in curtailing the pandemic. Additionally, this study shows that vaccination significantly reduces the severity of the disease and death rates despite low efficacy against COVID-19 infections. The African governments need to design vaccination strategies that increase vaccine uptake, such as an incentive-based approach.

Supply chains create global benefits from improved vaccine accessibility

Ensuring a more equitable distribution of vaccines worldwide is an effective strategy to control global pandemics and support economic recovery. We analyze the socioeconomic effects - defined as health gains, lockdown-easing effect, and supply-chain rebuilding benefit - of a set of idealized COVID-19 vaccine distribution scenarios. We find that an equitable vaccine distribution across the world would increase global economic benefits by 11.7% ($950 billion per year), compared to a scenario focusing on vaccinating the entire population within vaccine-producing countries first and then distributing vaccines to non-vaccine-producing countries. With limited doses among low-income countries, prioritizing the elderly who are at high risk of dying, together with the key front-line workforce who are at high risk of exposure is projected to be economically beneficial (e.g., 0.9%~3.4% annual GDP in India). Our results reveal how equitable distributions would cascade more protection of vaccines to people and ways to improve vaccine equity and accessibility globally through international collaboration.

Confronting 'chaos': a qualitative study assessing public health officials' perceptions of the factors affecting Tanzania's COVID-19 vaccine rollout

OBJECTIVES

Mass COVID-19 vaccination in Africa is required to end the pandemic. In low-income settings, street-level bureaucrats (SLBs), or public officials who interact directly with citizens, are typically responsible for carrying out vaccination plans and earning community confidence in vaccines. The study interviewed SLBs to assess their perceptions of the factors affecting COVID-19 vaccination rollout in Tanzania.

METHODS

We interviewed 50 SLBs (19 rural; 31 urban) responsible for implementing COVID-19 vaccination microplans across four diverse regions and districts of Tanzania in September 2021. Moreover, we conducted six in-depth interviews with non-governmental organisation representatives and seven focus group discussions with health facility governing committees. We asked for their perceptions of factors facilitating and challenging vaccine rollout according to three preidentified domains: political, health system and community. We analysed translated transcripts using a thematic analysis approach.

RESULTS

Political factors facilitating mass vaccination included the executive leadership change from a denialist president to a president who accepted vaccines and promoted transparency. Global integration, commercially and politically, also motivated vaccine acceptance. Political challenges included community confusion that emerged from the consecutive presidents' divergent communications and messaging by prominent religious antivaccination leaders. Health system factors facilitating vaccination included scaling up of immunisation sites and campaigns. Urban district officials reported greater access to vaccination sites, compared with rural officials. Limited financial resources for paying healthcare workers and for transport fuel and a lack of COVID-19 testing compromised mass vaccination. Furthermore, SLBs reported being inadequately trained on COVID-19 vaccine benefits and side effects. Having community sources of accurate information was critical to mass vaccination. Challenges at the community level included patriarchal gender dynamics, low risk perception, disinformation that the vaccine has satanic elements, and lack of trust in coronavirus vaccines.

CONCLUSION

Mass COVID-19 vaccination in Tanzania will require greater resources and investment in training SLBs to mitigate mistrust, overcome misinformation, and engage communities.

COVID-19 pandemic: what are the countries with low cases of COVID-19 doing right?

As of the 17th of September in 2021, the number of confirmed cases of COVID-19 over the world had reached 227.7 million, with around 8.2 million of those instances being reported in Africa and the island nations of the Atlantic and Pacific. The development of the COVID- 19 pandemic in Africa and other countries across the world has been significantly different from the first apocalyptic forecasts researchers in the scientific community provided. This is the case both in terms of the pandemic itself and its impact. This report investigates the factors – such as the political will to address COVID-19 through immediate and severe actions, collaborative leadership, and historical experience with infection disease outbreaks – that are responsible for the low reported cases of infections and deaths in two regions of the world: Africa and the island countries of the Atlantic and Pacific. In Africa, the political will to address COVID-19 through immediate and severe actions was high, and collaborative leadership was prevalent. Despite the fact that they have handled the pandemic in an effective way, vaccination continues to be a major worry because only a tiny fraction of the population in each of these locations has received at least one dose of vaccine. The healthcare systems in the countries located throughout these regions are in a poor shape, and an outbreak of a highly infectious coronavirus variety has the potential to overwhelm the already frail healthcare system and wreak havoc on these global regions. It is recommended that the leadership of these regions turn their attention inward and develop a collaborative strategy for the production of vaccines on a local level. Additionally, it is recommended that these regions make improvements to their healthcare systems so that they are adequately prepared to deal with the next major public health emergency.

High SARS-CoV-2 Seroprevalence after Second COVID-19 Wave (October 2020-April 2021), Democratic Republic of the Congo

Serologic surveys are important tools for estimating the true burden of COVID-19 in a given population. After the first wave of SARS-CoV-2 infections, a household-based survey conducted in Kinshasa, Democratic Republic of the Congo, estimated >292 infections going undiagnosed for every laboratory-confirmed case. To ascertain the cumulative population exposure in Kinshasa after the second wave of COVID-19, we conducted a prospective population-based cross-sectional study using a highly sensitive and specific ELISA kit. The survey included 2,560 consenting persons from 585 households; 55% were female and 45% male. The overall population-weighted, test kit-adjusted SARS-CoV-2 seroprevalence was 76.5% (95% CI 74.5%-78.5%). The seroprevalence was 4-fold higher than during the first wave, and positivity was associated with age, household average monthly income, and level of education. Evidence generated from this population-based survey can inform COVID-19 response, especially vaccination campaign strategies in the context of vaccine shortages and hesitancy.

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.

Systematic review and meta-analysis determining the effect of implemented COVID-19 guidelines on surgical oncology volumes and clinical outcomes

BACKGROUND

To provide for Coronavirus Disease 2019 (COVID-19) healthcare capacity, (surgical oncology) guidelines were established, forcing to alter the timing of performing surgical procedures. It is essential to determine whether these guidelines have led to disease progression. This study aims to give an insight into the number of surgical oncology procedures performed during the pandemic and provide information on short-term clinical outcomes.

MATERIALS AND METHODS

A systematic literature search was performed on all COVID-19 articles including operated patients, published before March 21, 2022. Meta-analysis was performed to visualize the number of performed surgical oncology procedures during the pandemic compared to the pre-pandemic period. Random effects models were used for evaluating short-term clinical outcomes.

RESULTS

Twenty-four studies containing 6762 patients who underwent a surgical oncology procedure during the pandemic were included. The number of performed surgical procedures for an oncological pathology decreased (-26.4%) during the pandemic. The number of performed surgical procedures for breast cancer remained stable (+0.3%). Moreover, no difference was identified in the number of ≥T2 (OR 1.00, P = 0.989), ≥T3 (OR 0.95, P = 0.778), ≥N1 (OR 1.01, P = 0.964) and major postoperative complications (OR 1.55, P = 0.134) during the pandemic.

CONCLUSION

The number of performed surgical oncology procedures during the COVID-19 pandemic decreased. In addition, the number of performed surgical breast cancer procedures remained stable. Oncological staging and major postoperative complications showed no significant difference compared to pre-pandemic practice. During future pandemics, the performed surgical oncology practice during the first wave of the COVID-19 pandemic seems appropriate for short-term results.

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.

The Vaccine World of COVID-19: India’s Contribution

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) eruption has left not only illness and mortality in its wake, but also an overwhelming threat to health policy, human regality, food security, and struggle worldwide. The accessibility and potential distribution of a protective and successful vaccination to communities throughout the world are being considered now not just, as a potential of overcoming these hurdles, but also as an example of human perseverance in the face of catastrophe. A vaccine is the only tool that can efficaciously deal with the COVID-19 catastrophe. Currently, more than 47 vaccines are permitted for emergency use in distinct parts of the world. India will play a significant role in the development of the high-priced Moderna shots and Pfizer Inc, therefore assisting in the immunization of a large portion of the world. Moreover, many of the internationally researched and developed vaccine laboratories seek manufacturing in Indian firms and companies for efficient and low-cost production of vaccines intending to provide to the world, hence, making India, a major role player during these pandemic times. This review highlights the Indian contribution to the globe for COVID-19 management.

Caregiver Willingness to Vaccinate Children with Pneumococcal Vaccines and to Pay in a Low-Resource Setting in China: A Cross-Sectional Study

To determine the vaccine hesitancy of pneumococcal conjugate vaccines (PCVs) in a low-resource setting in China and to identify associated factors, a face-to-face questionnaire survey was conducted in the city of Guilin, China, from December 2021 to March 2022, which comprised sociodemographic information, attitudes toward vaccines and pneumonia, and PCV13 vaccination willingness and willingness to pay (WTP). Stepwise logistic regression and Tobit regression models were fitted to identify factors associated with PCV13 vaccination willingness and WTP, respectively. In total, 1254 questionnaires were included, of which 899, 254, and 101 participants showed acceptance, hesitancy, and refusal to vaccinate their children with PCV13, respectively. Only 39.07% of participants knew about PCV13 before this survey. A total of 558 (48.40%) participants accepted the full payment of vaccination, and 477 (41.37%) other participants accepted the partial payment, with a median cost of CNY 920.00. Demographics, social and psychological context, and attitudes toward vaccines were all associated with PCV13 vaccination but varied for hesitators and refusers. There is a substantial local demand for vaccinating children with PCV13 and partial payment is widely accepted. More publicity and educational efforts and a socially supportive environment are required to alleviate vaccine hesitancy.

Tuberculosis, HIV/AIDS and Malaria Health Services in sub-Saharan Africa - A Situation Analysis of the Disruptions and Impact of the COVID-19 Pandemic

BACKGROUND

The unprecedented and ongoing COVID-19 pandemic has exposed weaknesses in African countries' health systems. The impact of shifted focus on COVID-19 for the past 2 years on routine health services, especially those for the epidemics of Tuberculosis, HIV/AIDS and Malaria, have been dramatic in both quantity and quality.

METHODS

In this article, we reflect on the COVID-19 related disruptions on the Tuberculosis, HIV/AIDS and Malaria routine health services across Africa.

RESULTS

The COVID-19 pandemic resulted in disruptions of routine health services and diversion of already limited available resources in sub-Saharan Africa. As a result, disease programs like TB, malaria and HIV have recorded gaps in prevention and treatment with the prospects of reversing gains made towards meeting global targets. The extent of the disruption is yet to be fully quantified at country level as most data available is from modelling estimates before and during the pandemic.

CONCLUSIONS

Accurate country-level data is required to convince donors and governments to invest more into revamping these health services and help prepare for managing future pandemics without disruption of routine services. Increasing government expenditure on health is a critical part of Africa's economic policy. Strengthening health systems at various levels to overcome the negative impacts of COVID-19, and preparing for future epidemics will require strong visionary political leadership. Innovations in service delivery and technological adaptations are required as countries aim to limit disruptions to routine services.

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.

A Qualitative Evaluation of COVID-19 Preventative Response Activities in South Kivu, Democratic Republic of the Congo

OBJECTIVE

In this evaluation of COVID-19 preventative response programs in South Kivu, Democratic Republic of the Congo (DRC), we aimed to explore community understandings of COVID-19, assess operational successes and challenges of COVID response activities, and identify barriers to practicing COVID-19 preventative behaviors.

METHODS

Thirty-one semi-structured interviews were conducted from April to September 2021 in South Kivu, DRC, with community members (n = 16) and programmatic stakeholders (n = 15) (healthcare providers, government officials, and developmental and NGO staff engaged in COVID-19 response).

FINDINGS

Most community members were aware of COVID-19 and its global burden, but few were aware of local transmission in their area. Some community members attributed COVID-19 to actions of malevolent neighbors, miasma ("bad air"), or spirits. Awareness of COVID-19 preventative measures was widespread, largely because of radio and TV health promotion programs. Community members and programmatic stakeholders both said community-level non-compliance to COVID-19 preventative measures was high despite high awareness of preventative methods. Community members expressed concern that face masks distributed as part of preventative programs contained the COVID-19 virus. Programmatic stakeholders emphasized the need for broader health system strengthening with improved coordination, provision of resources to health facilities at the provincial level, and prioritization of research. Lessons learned from addressing Ebola were leveraged for COVID-19 health promotion, rapid training of healthcare personnel, and surveillance.

CONCLUSIONS

Community-informed approaches are needed for effective COVID-19 preventative response programs in South Kivu, DRC. Our study identified successes and challenges in COVID-19 response activities. Future research should assess the effectiveness of integrating preventive programs with COVID-19 vaccination efforts.

Black People Narrate Inequalities in Healthcare Systems that Hinder COVID-19 Vaccination: Evidence from the USA and the UK

The coronavirus disease 2019 (COVID-19) pandemic is an unprecedented global health emergency. As a novel condition, there is no known definitive treatment for the condition, except for the use of vaccines as a control measure. In the literature, the issue of inequalities in healthcare systems has been documented as a hindrance to COVID-19 vaccination; however, the specific inequalities in healthcare systems that hinder COVID-19 vaccination are poorly understood. Guided by the fundamental cause theory (FCT), this study aims to address this gap among Black people, a minority group vulnerable to inequalities in healthcare systems. Thirty-five Black people (age range = 21-58 years) residing in either the United States of America (USA) or the United Kingdom (UK) participated in this study. Qualitative data were collected and analyzed using thematic analysis. Most USA participants and a few UK participants narrated that no inequalities in healthcare systems hinder them from receiving COVID-19 vaccines. Contrarily, most UK participants and a few USA participants narrated inequalities in healthcare systems that hinder them from receiving COVID-19 vaccines. These are mistrust of the healthcare system, health policies regarding COVID-19 vaccination, historical factors (such as historical abuse of Black bodies by health professionals), residential location, and dissatisfaction with health services. In terms of what governments must do to correct these inequalities, participants recommended the need for acknowledgment and community engagement. This is the first international collaboration to examine this problem. Important implications for theory, healthcare systems, and COVID-19 vaccination program planning are highlighted. Finally, there are members of other minority groups and vulnerable communities who are not Black people. Such groups could face unique inequalities that hinder COVID-19 vaccination. Therefore, future studies should include such groups.

COVID-19 Vaccine Acceptability Among Healthcare Facility Workers in Sierra Leone, the Democratic Republic of Congo and Uganda: A Multi-Centre Cross-Sectional Survey

Objectives: This cross-sectional survey explored COVID-19 vaccine acceptability among public healthcare facility workers in Kambia (Sierra Leone), Goma (Democratic Republic of Congo) and Masaka (Uganda). Methods: Questionnaire-based interviews conducted between April-October 2021 explored participants' knowledge and perceptions of, and attitudes towards, the COVID-19 pandemic and COVID-19 vaccines, as well as COVID-19 vaccine acceptability (defined as uptake of ≥1 dose or intent to get vaccinated). Results: Whilst most (n = 444; 81.8%) of the 543 participants had one or more concerns about COVID-19 vaccines, 487 (89.7%) nonetheless perceived that they were important for pandemic control. Most participants from Kambia or Masaka either were vaccinated (n = 137/355; 38.6%) or intended to get vaccinated (n = 211/355; 59.4%) against COVID-19. In Goma, all 188 participants were unvaccinated; only 81 (43.1%) participants intended to get vaccinated, and this was associated with positive perceptions about COVID-19 vaccines. In Goma, the most common reasons for not wanting a COVID-19 vaccine were concerns that the vaccines were new (n = 75/107; 70.1%) and fear of side effects (n = 74/107; 69.2%). Conclusion: Reported COVID-19 vaccine acceptability was high among healthcare facility workers in Kambia and Masaka. The lower vaccine acceptability in Goma may highlight the importance of social mobilisation and accurate, accessible information that addresses specific concerns.

The acceptance of COVID-19 vaccine at early stage of development and approval: A global systematic review and meta-analysis

Background

Vaccination seems to be the most effective way to prevent and control the spread of COVID-19, a disease that has adversely impacted the lives of over 7 billion people across the globe. Vaccine hesitancy represents an important threat to combat infectious diseases worldwide. This study aims to inspect the COVID-19 vaccine acceptance rate worldwide and the regional variation of the acceptance rates among the general population and healthcare workers across different territories of the world. In addition, it compares the vaccine acceptance rates between the pre- and post-vaccine approval periods.

Method

A comprehensive systematic review was conducted using PRISMA statements. After quality evaluation, the data from eligible studies were analyzed using the random effect model. Q-test and I2 statistics were used to search for heterogeneity. The publication bias was assessed by using Egger’s test and funnel plot.

Results

The combined COVID-19 vaccine acceptance rate among the general population and healthcare workers (n = 1,581,562) was estimated at 62.79% (95% CI: 58.98–66.60). The acceptance rate substantially decreased from 66.29% (95% CI: 61.24–71.35) to 56.69% (95% CI: 48.68–64.71) among the general population from the pre-to post-vaccine approval periods but remained almost constant at 58.25% (95% CI: 46.52–69.97) among healthcare workers. The acceptance rates also varied in different regions of the world. The highest acceptance rate was found in the South-East Asia region at 70.18% (95% CI: 58.12–82.25) and the lowest was found in African Region at 39.51% (95% CI: 23.42–55.59).

Conclusion

Low COVID-19 vaccine acceptance rate might be a massive barrier to controlling the pandemic. More research is needed to address the responsible factors influencing the low global rate of COVID-19 vaccine acceptance. Integrated global efforts are required to remove the barriers.

Third wave of COVID-19 pandemic in Africa: Challenges and recommendations

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has evolved in different waves and is currently in its third wave for the majority of countries around the world. Each wave emanated with its own set of challenges. Lower- and middle-income countries such as most African countries have faced additional challenges compared to high-income countries. This paper highlights the challenges faced by Africa during the third wave of COVID-19 and proposes recommendations and strategies to contain the spread. We conducted a mini-review for the newly released articles and researches about the challenges faced by Africa during COVID-19. Fragmented healthcare sectors, limited healthcare resources and emergence of co-infections in COVID-19 patients, inadequate vaccination rollout and political conflicts are the major challenges faced by the African countries. Our recommendations to defeat this outbreak and subsequent pandemics is to raise the public's awareness about vaccines through campaigns and social media in order to lessen vaccine hesitancy. Governments as well should focus on under-served and vulnerable populations, patients with comorbidities, and communities living in endemic-striking settings as these people are more prone to the severe form of the disease. Moreover, by adopting socio-ecological perspectives, one can implement multi-level integrated interventions to help control COVID-19 more effectively.

COVID-19 vaccine hesitancy amongst healthcare workers: An assessment of its magnitude and determinants during the initial phase of national vaccine deployment in Nigeria

BACKGROUND

While vaccination plays a critical role in the global response to the COVID-19 pandemic, vaccine rollout remains suboptimal in Nigeria and other Low- and Middle-income countries (LMICs). This study documents the level of hesitancy among health workers (HWs) during the initial COVID-19 vaccine deployment phase in Nigeria and assesses the magnitude and determinants of hesitancy across Nigeria.

METHODS

A cross sectional study across all States in Nigeria was conducted with over 10,000 HWs interviewed between March and April 2021. Data were cleaned and analyzed with proportions and confidence intervals of hesitancy documented and stratification by HW category. We compared the level of confidence/acceptance to be vaccinated across Nigeria and documented the sources of negative information amongst HWs who refused the vaccine.

FINDINGS

Among the 10 184 HWs interviewed, 9 369 [92% (95% CI= 91, 92)] were confident of the COVID-19 vaccines and were already vaccinated at the time of this survey. Compared to HWs who were less than 20 years old, those aged 50 - 59 years were significantly more confident of the COVID-19 vaccines and had been vaccinated (OR=3.8, 95% CI=2.3 - 6.4, p<0.001). Only 858 (8%) of the HWs interviewed reported being hesitant with 57% (479/858) having received negative information, with the commonest source of information from social media (43.4%.).

INTERPRETATION

A vast majority of HWs who were offered COVID-19 vaccines as part of the first phase of national vaccine roll out were vaccinated and reported being confident of the COVID-19 vaccines. The reported hesitancy was due mainly to safety issues, and negative information about vaccines from social media. The issues identified remain a significant risk to the success of subsequent phases of the vaccine rollout in Nigeria.

FUNDING

None.

COVID-19 Vaccine Coverage and Potential Drivers of Vaccine Uptake among Healthcare Workers in SOMALIA: A Cross-Sectional Study

Healthcare workers (HCWs) are one of the most vulnerable groups for contracting COVID-19 and dying as a result of it. Over 10,000 HCWs in Africa have been infected with COVID-19, according to the World Health Organization, making it a substantial occupational health threat for HCWs. To that end, Somalia’s Ministry of Health has ordered that all healthcare personnel obtain the COVID-19 vaccination to safeguard themselves and the community they serve. In this investigation, we aimed to assess the COVID-19 vaccination coverage and its associated factors among healthcare workers in Somalia. A cross-sectional study was employed to examine COVID-19 vaccination coverage among healthcare personnel in Somalia. The data were obtained via an online questionnaire supplied by Google forms between December 2021 and February 2022, where a total of 1281 healthcare workers from the various federal states of Somalia were recruited. A multinomial regression analysis was used to analyse the factors associated with COVID-19 vaccine uptake. Overall, 1281 HCWs participated (630 females, 651 males) with a mean age and standard deviation of 27.7 years ± 7.1. The overall vaccine coverage was 37.4%. Sex, age, the state of residency, education level, specialization, hospital COVID-19 policy, vaccine availability at the centre, COVID-19 treatment centre, and health facility level were the factors that influenced the COVID-19 vaccine uptake among health professionals in Somalia. Male healthcare employees were 2.2 times (odds ratio-OR = 2.2; confidence interval-CI: 1.70, 2.75, p < 0.001) more likely than female healthcare workers to be fully vaccinated. The survey discovered that the COVID-19 vaccine coverage among health professionals was quite low, with the major contributing factors being accessibility, security challenges and literary prowess. Additional efforts to enhance vaccination uptake are needed to improve the COVID-19 vaccination coverage.

Willingness to accept COVID-19 vaccination among people living with HIV in a high HIV prevalence community

Background

People living with HIV (PLWH) may have a poorer prognosis with COVID-19 infection and are an important population for COVID-19 vaccination. We assessed the willingness and reasons for COVID-19 vaccine acceptance or hesitancy among PLWH in South Africa.

Methods

We conducted a cross-sectional study consisting of telephone interviews with a randomly selected subset of participants enrolled in a prospective observational cohort study evaluating a decentralized antiretroviral therapy (ART) delivery program in South Africa. Questions assessed willingness to accept a future COVID-19 vaccine, concerns regarding COVID-19 vaccination, and overall vaccine confidence. Interviews were conducted between September 2020 and January 2021. We evaluated participant demographics, sources of COVID-19 information, stigma and medical mistrust, uptake of non-pharmaceutical interventions, and socioeconomic impacts of the COVID-19 pandemic as potential covariates of willingness to accept vaccination.

Results

We completed interviews with 213 participants; 153 (72%) were female, median age 35y, and 100 (47%) had completed secondary school. Among the participants, 121 (57%) were willing to accept future vaccination, 46 (22%) were unsure, and 45 (21%) stated they did not intend to be vaccinated. Fear of side effects, reported by 42 (20%), was the most common concern about COVID-19 vaccination. Older age was associated with willingness to accept vaccination (aOR 1.75 for every 10-year increase in age, 95% CI 1.10–2.78, p = 0.02), while higher medical mistrust related to COVID-19 (aOR 0.21, 95% CI 0.093–0.45, p < 0.001) and use of social media for COVID-19 information (aOR 0.30, 95% CI 0.11–0.84, p = 0.02) were associated with lower willingness to accept vaccination.

Conclusions

In this cohort of PLWH in South Africa, over half were willing to accept COVID-19 vaccination, although a substantial proportion remained unsure or were not willing to be vaccinated. Public health messaging should emphasize the safety and efficacy of COVID-19 vaccination and address misinformation and medical mistrust among PLWH. Ongoing efforts to ensure access to COVID-19 vaccines for vulnerable populations are crucial.

A cross-sectional regional study looking at the factors responsible for the low COVID-19 vaccination rate in Nigeria

Introduction

COVID-19 vaccination has been rolled out in Nigeria, with low uptake often attributed to shortage of the vaccine. We set out to find out the current trend so far and to the best of our knowledge, our study is one of the early studies since the roll out in the region looking at the real situation on ground. This will guide multidisciplinary decision making at increasing uptake of the vaccine.

Methods

this is a descriptive cross-sectional study in the 5 South-Eastern States in Nigeria. A structured questionnaire was given to the members of the public to answer themselves or via the help of an interviewer. Data was analysed in SPSS and associations between variables compared using Chi square.

Results

there are 1283 respondents in this study. Of this number, only 105 (8.2%) have had at least one of the vaccine doses. Stated reasons for not having been vaccinated are side effects (n=370, 31.5%), access to a vaccination centre (n= 239, 20.4%) and belief in one’s own immunity 186 (15.5). Having a health-related degree (p-value of 0.021), non-governmental employees (p-value of 0.003), private sector employees (p-value of 0.029) and public sector employees (p-value of 0.009) are associated with relatively higher vaccination rates.

Conclusion

vaccination rate in Nigeria is still very low. Fear of side effect which is enhanced by mystical thinking is the leading factor for low turnout not just shortages. All forms of employed jobs, age and higher qualification all have significant p-values (p<0.05) and associated with higher uptake of the vaccine.

Prioritizing COVID-19 vaccination efforts and dose allocation within Madagascar

Background

While mass COVID-19 vaccination programs are underway in high-income countries, limited availability of doses has resulted in few vaccines administered in low and middle income countries (LMICs). The COVID-19 Vaccines Global Access (COVAX) is a WHO-led initiative to promote vaccine access equity to LMICs and is providing many of the doses available in these settings. However, initial doses are limited and countries, such as Madagascar, need to develop prioritization schemes to maximize the benefits of vaccination with very limited supplies. There is some consensus that dose deployment should initially target health care workers, and those who are more vulnerable including older individuals. However, questions of geographic deployment remain, in particular associated with limits around vaccine access and delivery capacity in underserved communities, for example in rural areas that may also include substantial proportions of the population.

Methods

To address these questions, we developed a mathematical model of SARS-CoV-2 transmission dynamics and simulated various vaccination allocation strategies for Madagascar. Simulated strategies were based on a number of possible geographical prioritization schemes, testing sensitivity to initial susceptibility in the population, and evaluating the potential of tests for previous infection.

Results

Using cumulative deaths due to COVID-19 as the main outcome of interest, our results indicate that distributing the number of vaccine doses according to the number of elderly living in the region or according to the population size results in a greater reduction of mortality compared to distributing doses based on the reported number of cases and deaths. The benefits of vaccination strategies are diminished if the burden (and thus accumulated immunity) has been greatest in the most populous regions, but the overall strategy ranking remains comparable. If rapid tests for prior immunity may be swiftly and effectively delivered, there is potential for considerable gain in mortality averted, but considering delivery limitations modulates this.

Conclusion

At a subnational scale, our results support the strategy adopted by the COVAX initiative at a global scale.

COVID-19 Vaccine Challenges in Developing and Developed Countries

The coronavirus disease 2019 (COVID-19) pandemic has led to significant psychological and economical distress. Within a year after COVID-19 was declared a pandemic, several vaccines against COVID-19 were approved for emergency use. The journey from vaccine discovery to global herd immunity against COVID-19 continues to present significant challenges revolving around its development, affordability, accessibility, and acceptability at both a country level and an individual level. The main challenge faced by developed countries is the acceptability of the COVID-19 vaccine and the main challenge faced by developing countries is the affordability and accessibility of the COVID-19 vaccine.

Uptake of the COVID-19 vaccine among healthcare workers in Malawi

BACKGROUND

Little is known about coronavirus disease 2019 (COVID-19) vaccination in Africa. We sought to understand Malawian healthcare workers' (HCWs') COVID-19 vaccination and its hypothesized determinants.

METHODS

In March 2021, as the COVID-19 vaccine roll-out commenced in Malawi, we surveyed clinical and lay cadre HCWs (n=400) about their uptake of the vaccine and potential correlates (informed by the WHO Behavioral and Social Drivers of COVID-19 Vaccination framework). We analyzed uptake and used adjusted multivariable logistic regression models to explore how 'what people think and feel' constructs were associated with HCWs' motivation to be vaccinated.

RESULTS

Of the surveyed HCWs, 82.5% had received the first COVID-19 vaccine dose. Motivation (eagerness to be vaccinated) was strongly associated with confidence in vaccine benefits (adjusted OR [aOR] 9.85, 95% CI 5.50 to 17.61) and with vaccine safety (aOR 4.60, 95% CI 2.92 to 7.23), but not with perceived COVID-19 infection risk (aOR 1.38, 95% CI 0.88 to 2.16). Of all the information sources about COVID-19 vaccination, 37.5% were reportedly negative in tone.

CONCLUSIONS

HCWs in Malawi have a high motivation to be vaccinated and a high COVID-19 vaccine uptake. Disseminating vaccine benefits and safety messages via social media and social networks may be persuasive for individuals who are unmotivated to be vaccinated and less likely to accept the COVID-19 vaccine.

COVID-19 vaccines for children and adolescents in Africa: aligning our priorities to situational realities

The evolving COVID-19 pandemic is an unprecedented global public health crisis that continues to have a major impact on the African continent. Most countries within Africa are facing significant challenges vaccinating their populations for COVID-19. Inadequate COVID-19 vaccine supply, weaknesses in health system infrastructure, COVID-19 misinformation and disinformation, and ineffective health risk communication are contributing to low adult vaccination rates on the continent. Without sufficient COVID-19 vaccine coverage on the African continent, the prolonged social, economic and health impacts of this public health crisis are likely to exacerbate pre-existing social-structural issues in this part of the world. In this paper, we highlight trends in SARS-CoV-2 infections among children and adolescents (CA), compare COVID-19 vaccination patterns in Africa to those in high-income countries, and discuss some of the benefits, challenges and unknowns associated with vaccinating CA for COVID-19. In light of ongoing COVID-19 vaccine supply challenges and the slow progress that the African continent is making towards vaccinating the adult population, we suggest that the immediate priority for Africa is to accelerate COVID-19 vaccinations among adults (particularly high-risk populations) and vulnerable CA (ie, those who are immunocompromised and/or living with certain medical conditions). Accelerating the roll-out of COVID-19 vaccines and rapidly achieving high levels of vaccination coverage in the adult population will free up capacity to vaccinate CA sooner rather than later. While we hope that COVID-19 vaccines will soon become available to CA throughout Africa, countries must continue to prioritise non-pharmaceutical interventions.

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.

Analysis of the COVID-19 pandemic: lessons towards a more effective response to public health emergencies

Background

The pandemic of Coronavirus Disease 2019 (COVID-19) is a timely reminder of the nature and impact of Public Health Emergencies of International Concern. As of 12 January 2022, there were over 314 million cases and over 5.5 million deaths notified since the start of the pandemic. The COVID-19 pandemic takes variable shapes and forms, in terms of cases and deaths, in different regions and countries of the world. The objective of this study is to analyse the variable expression of COVID-19 pandemic so that lessons can be learned towards an effective public health emergency response.

Methods

We conducted a mixed-methods study to understand the heterogeneity of cases and deaths due to the COVID-19 pandemic. Correlation analysis and scatter plot were employed for the quantitative data. We used Spearman’s correlation analysis to determine relationship strength between cases and deaths and socio-economic and health systems. We organized qualitative information from the literature and conducted a thematic analysis to recognize patterns of cases and deaths and explain the findings from the quantitative data.

Results

We have found that regions and countries with high human development index have higher cases and deaths per million population due to COVID-19. This is due to international connectedness and mobility of their population related to trade and tourism, and their vulnerability related to older populations and higher rates of non-communicable diseases. We have also identified that the burden of the pandemic is also variable among high- and middle-income countries due to differences in the governance of the pandemic, fragmentation of health systems, and socio-economic inequities.

Conclusion

The COVID-19 pandemic demonstrates that every country remains vulnerable to public health emergencies. The aspiration towards a healthier and safer society requires that countries develop and implement a coherent and context-specific national strategy, improve governance of public health emergencies, build the capacity of their (public) health systems, minimize fragmentation, and tackle upstream structural issues, including socio-economic inequities. This is possible through a primary health care approach, which ensures provision of universal and equitable promotive, preventive and curative services, through whole-of-government and whole-of-society approaches.

Understanding the Facilitators and Barriers to COVID-19 Vaccine Uptake Among Teachers in the Sagnarigu Municipality of Northern Ghana: A Cross-Sectional Study

Purpose

This research aims to identify facilitators and barriers to COVID-19 vaccination intention and uptake among teachers in the Sagnarigu Municipality of Ghana.

Methods

The survey collected quantitative data from the teachers using a cross-sectional study design. Logistic regression analysis was used to identify facilitators and barriers to COVID-19 vaccination.

Results

The teachers’ (N = 421) COVID-19 vaccination intention before rollout, after rollout, and actual uptake were 49%, 63%, and 11%, respectively. In a multiple regression analysis, key facilitators of intention were vaccinated against hepatitis B (AOR: 2.5, 95 CI: 1.03, 4.93), willingness to recommend COVID-19 vaccine to students (AOR: 4.78,95% CI: 1.95, 11.70), adequacy of information about the expectation of the COVID-19 vaccine (2.42, 95% CI: 1.04, 5.56), and the disbelief that COVID-19 vaccine will cause illness (AOR: 2.50, 95% CI: 1.16, 5.33). Unconfident in the COVID-19 vaccine (AOR: 0.01, 95% CI: 0.001, 0.118), perception of not being susceptible to COVID-19 (AOR: 0.38, 95% CI: 0.17, 0.88), and feeling uncomfortable getting the vaccine (AOR: 0.17, 95% CI: 0.08, 0.38) were barriers to COVID-19 vaccination intention. Key facilitators of COVID-19 vaccine uptake were being a Christian (AOR: 3.63, 95% CI: 1.60, 8.24), teaching in the Senior High School (SHS)/technical (AOR: 13.43, 95% CI: 1.90, 9.48). Barriers to the vaccine uptake were uncomfortable getting the vaccine (AOR: 0.06, 95% CI: 0.06, 0.49), disbelief that vaccinating teachers will reduce school absenteeism (AOR: 0.45, 95% CI: 0.18, 1.07), unconfident in the COVID-19 vaccine (AOR: 0.45, 95 CI: 0.18, 1.07), and unavailability of the COVID-19 vaccine.

Conclusion

Facilitators and barriers to COVID-19 vaccination are multifaceted, including sociodemographic, health beliefs, and contextual factors. Addressing the obstacles to COVID-19 vaccination is crucial for adequate COVID-19 vaccine coverage among teachers in Ghana.

Performance of a rapid antigen test for SARS-CoV-2 in Kenya

Testing for SARS-CoV-2 in resource-poor settings remains a considerable challenge. Gold standard nucleic acid tests are expensive and depend on availability of expensive equipment and highly trained laboratory staff. More affordable and easier rapid antigen tests are an attractive alternative. This study assessed field performance of such a test in western Kenya. We conducted a prospective multi-facility field evaluation study of NowCheck COVID-19 Ag-RDT compared to gold standard PCR. Two pairs of oropharyngeal and nasopharyngeal swabs were collected for comparative analysis. With 997 enrolled participants the Ag-RDT had a sensitivity 71.5% (63.2-78.6) and specificity of 97.5% (96.2-98.5) at cycle threshold value <40. Highest sensitivity of 87.7% (77.2-94.5) was observed in samples with cycle threshold values ≤30. NowCheck COVID-19 Ag-RDT performed well at multiple healthcare facilities in an African field setting. Operational specificity and sensitivity were close to WHO-recommended thresholds.

Increasing the frequency of omicron variant mutations boosts the immune response and may reduce the virus virulence

The coronavirus has posed a serious threat to the world since its discovery in Wuhan in 2019. Beta, gamma, delta, and the final omicron variants have emerged as a result of several mutations in the virion structure. The Australian Omicron S protein variant contains 37 mutations out of a total of 67 mutations. According to preliminary data from South Africa, Omicron variant infection is not associated with any particular symptoms. The purpose of this research was to determine how changes in the structure of the S protein alter the protein's interaction with the ACE2 receptor. The Omicron variant stimulates the immune response more than the wild strain.

COVID-19, measles, and yellow fever: The need to reinforce vaccination in the Democratic Republic of Congo

The immunization programs have been jeopardized all over the world due to the stay-at-home constraints imposed, to mitigate the ongoing COVID-19 pandemic. This has directly or indirectly placed the global health care system in peril, resulting in an overlapping public health crisis. With this commentary, we aim to accentuate the need to reinforce vaccination in the Democratic Republic of Congo, in lieu of the intersecting COVID-19, measles, and yellow fever outbreak, besides, providing recommendations so as to help alleviate the situation.

Are we there yet? Unbundling the potential adoption and integration of telemedicine to improve virtual healthcare services in African health systems

Since the outbreak of COVID-19, the attention has now shifted towards universal vaccination to gracefully lift strict COVID-19 restrictions previously imposed to contain the spread of the disease. Sub-Saharan Africa is experiencing an exponential increase of infections and deaths coupled with vaccines shortages, personal protective equipment, weak health systems and COVID-19 emerging variants. Some developed countries integrated telemedicine to reduce the impacts of the shortage of healthcare professionals and potentially reduce the risk of exposure, ensuring easy delivery of quality health services while limiting regular physical contact and direct hospitalization. However, the adoption of telemedicine and telehealth is still nascent in many sub-Saharan Africa countries. Therefore, this study reflects on progress made towards the use of telemedicine, virtual health care services, challenges encountered, and proffers ways to address them. We conducted a systematic literature review to synthesise literature on telemedicine in sub-Saharan Africa. The study revealed that telemedicine provides unprecedented benefits such as improving efficiency, effective utilization of healthcare resources, forward triaging, prevention of medical personnel infection, aiding medical students' clinical observation and participation, and assurance of social support for patients. However, the absence of policy on virtual care and political will, cost of sustenance of virtual health care services, inadequate funding, technological and infrastructural barriers, patient and healthcare personnel bias on virtual care and cultural barriers are identified as limiting factors to the adoption of virtual health care in many African health systems. To alleviate some of these barriers, we recommend the development of robust policies and frameworks for virtual health care, the inclusion of virtual care in the medical school curriculum, supporting virtual care research and development, increasing health funding, removing monopolisation of telecommunication services, developing of virtual health solutions that address eccentricities of African health systems.
