COVID-19 vaccine acceptance among Bangladeshi adults: Understanding predictors of vaccine intention to inform vaccine policy

COVID-19 vaccination uptake in remote areas-Evidence from a panel survey in Bangladesh

BACKGROUND

Vaccination has proven to be an essential strategy in combating the COVID-19 pandemic. This study aims to discern the factors influencing both the intentions for and actual behavior regarding COVID-19 vaccination among remote, rural populations in Bangladesh.

METHODS

The study utilized panel survey data comprising 1,698 randomly selected household heads. These are predominantly illiterate, of Muslim religion, middle-aged, and male, with agriculture or day labor as primary income source. They reside in 36 locations distributed along the whole 250 km length of the Jamuna River in Bangladesh. Data collection occurred through face-to-face and telephone interviews conducted between September 2021 and October 2022. Descriptive statistics and Ordinary Least Squares regression models were employed to assess influence factors for COVID-19 vaccination intentions and uptake. The analyses considered the constructs of the Health Belief Model alongside sociodemographic characteristics such as gender, age, religion, education, and income source.

RESULTS

Survey respondents showed a notably high willingness to receive the COVID-19 vaccine promptly upon its availability. However, the effectiveness of the Health Belief Model in elucidating COVID-19 vaccination uptake was limited, except for its availability component. Older individuals, those with higher levels of education, and individuals employed in government or formal sector occupations were prompt in receiving the COVID-19 vaccine as it became available. Gender, religion, and the presence of dependents in the household did not exert a significant influence on vaccination uptake.

CONCLUSIONS

The results indicate that a strong willingness to receive the COVID-19 vaccine correlated with an increased likelihood of vaccine uptake once it was available. These findings suggest that a widespread distribution of COVID-19 vaccines to low-income and remote areas could have served as a vital strategy in mitigating the COVID-19 pandemic.

Coronavirus disease 2019 vaccination acceptance and associated factors among residents of Dire Dawa Administration, Eastern Ethiopia: a community-based cross-sectional study

BACKGROUND

Corona virus disease 2019 (COVID-19) is an extremely contagious viral infection caused by the severe acute respiratory syndrome coronavirus 2. Understanding the willingness of the community to receive the COVID-19 vaccine will help in the development and implementation of effective COVID-19 vaccination promotion programs. Therefore, we aimed to assess the level of COVID-19 vaccine acceptance and associated factors among residents of Dire Dawa Administration, Eastern Ethiopia.

METHODS

A community-based cross-sectional study was conducted among 840 residents in Dire Dawa Administration from May 18th to June 18th, 2021. Multistage cluster sampling followed by systematic random sampling was used to select respondents. A pretested interviewer-administered structured questionnaire was used to collect the data from respondents. Bivariable and multivariable logistic regression were used to identify predictors of COVID-19 vaccine acceptance. The odds ratio (OR), along with a 95% confidence interval (CI), was used to estimate the strength of the association.

RESULTS

Out of 840 respondents recruited, the proportion of COVID-19 vaccine acceptance was found to be 54.4% (457/840); (95% CI: 51.0%, 57.7%) Being male [AOR = 1.85, 95% CI: (1.35, 2.54), P < 0.001], not having a current habit of substance use [AOR = 2.38, 95% CI: (1.73, 3.26), P < 0.001], having a monthly income of less than 51.31 USD [AOR = 0.19, 95% CI: (0.04, 0.88), P = 0.001]; and not having a prior history of vaccination experience [AOR = 0.40, 95% CI: (0.29, 0.54), P < 0.001] were significantly associated with COVID-19 vaccine acceptance.

CONCLUSION

This study reveals that the proportion of COVID-19 vaccine acceptance among residents of Dire Dawa Administration, Eastern Ethiopia, was 54.4%. Factors like being male and not having a current habit of substance use were positively associated, whereas having a monthly income of less than 51.31 USD and not having a prior history of vaccination experience were negatively associated with COVID-19 vaccine acceptance. Health information dissemination and economic empowerment are crucial to improving COVID-19 vaccine acceptance among the community. This study provides valuable data for policymakers to plan early vaccination programs and tackle the challenges identified in the study.

Relative contribution of biomedical, demographic, and socioeconomic factors to COVID-19 vaccine receipt in rural India

BACKGROUND

In the first year of roll-out, vaccination for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) prevented almost 20 million deaths from coronavirus disease 2019 (COVID-19). Yet, little is known about the factors influencing access to vaccination at the individual level within rural poor settings of low-income countries. The aim of this study was to examine determinants of vaccine receipt in rural India.

METHODS

A census of a rural village in Tamil Nadu was undertaken from June 2021 to September 2022. We surveyed 775 participants from 262 households. Household-level data on socioeconomic status (SES), water, sanitation, and hygiene practices, and individual-level demographic information, travel history, and biomedical data, including anthropometry, vital signs, and comorbidities, were collected. Logistic regression models with 5-fold cross-validation were used to identify the biomedical, demographic, and socioeconomic determinants of vaccine receipt and the timing of receipt within the first 30 days of eligibility. Vaccine ineligible participants were excluded leaving 659 eligible participants. There were 650 eligible participants with complete biomedical, demographic, and socioeconomic data.

RESULTS

There were 68.0% and 34.0% of individuals (N = 650) who had received one and two vaccine doses, respectively. Participants with household ownership of a permanent account number (PAN) or ration card were 2.15 (95% CI:1.32-3.52) or 3.02 (95% CI:1.72-5.29) times more likely to receive at least one vaccine dose compared to households with no ownership of such cards. Participants employed as housewives or self-employed non-agricultural workers were 65% (95% CI:0.19-0.67) or 59% (95% CI:0.22-0.76) less likely to receive at least one vaccine dose compared to salaried workers. Household PAN card ownership, occupation and age were linked to the timing of vaccine receipt. Participants aged ≤18 and 45-60 years were 17.74 (95% CI:5.07-62.03) and 5.51 (95% CI:2.74-11.10) times more likely to receive a vaccine within 30 days of eligibility compared to 19-44-year-olds. Biomedical factors including BMI, vital signs, comorbidities, and COVID-19 specific symptoms were not consistently associated with vaccine receipt or timing of receipt. No support was found that travel history, contact with COVID-19 cases, and hospital admissions influenced vaccine receipt or timing of receipt.

CONCLUSION

Factors linked to SES were linked to vaccine receipt, more so than biomedical factors which were targeted by vaccine policies. Future research should explore if government interventions including vaccine mandates, barriers to vaccine access, or peer influence linked to workplace or targeted vaccine promotion campaigns underpin these findings.

Willingness to Embrace COVID-19 Vaccination Amongst Residents in a Low-Income Nation: Insights From a Cross-Sectional Study on a Limited Cohort

The global pandemic had a significant impact on countries around the world, both politically and socioeconomically. It is crucial that swift decisions and actions need to be taken to prevent negative outcomes. The development of vaccines has emerged as a potential necessity for countries worldwide. Ethiopia began vaccinating health professionals and high-risk individuals in March 2021, according to a report from the World Health Organization citing the Ethiopian Federal Ministry of Health. This study aimed to assess the determinants of willingness to receive the COVID-19 vaccine among Debre Markos city administration residents. A community-based cross-sectional study design was employed to recruit 845 individuals as a sample. Descriptive statistics and logistic regression were used as statistical analysis techniques. Among the total 845 samples, the overall response rate was 98.34%. Two hundred forty-two participants showed their willingness to receive vaccines. Age (AOR = 2.56; 95%CI = [1.87-3.23]), sex (Female) (AOR = 3.45; 95% CI = [2.07-5.26]), having children (AOR = 1.21; 95% CI = [1.02-1.90]), and Chronic Disease (AOR = 2.98; 95% CI = [1.67-3.50]) were significantly and positively associated with willingness to receive COVID 19 vaccines at 95% CI. Although most of the participants were aware of the possibility of COVID-19 to cause fever; and its transmission, only a small percentage of the total participants showed their willingness to receive the vaccine if it was available to them. Elderly and individuals with chronic diseases need to get a priority of taking those vaccinations.

Acceptance of COVID-19 vaccine booster dose among the people of Bangladesh: A cross-sectional study

Vaccine booster dose (VBD) provides a potential therapeutic alliance in preventing breakthrough infection and new variant's arrival while preserving long-lasting host immunity. This study aimed to analyze COVID-19 VBD willingness and identified the key determinants of VBD acceptance among the general people of Bangladesh. This survey-based study applied a quantitative research paradigm. A validated, anonymous, and multi-item questionnaire was adopted through a theoretical review of pertinent literature on the topic. Data were collected between August 2022─October 2022, and sampling was done randomly. A total of 704 individuals were invited via face-to-face interview approach; however, 13.8 % of them declined to give consent, which resulted in the participation of 607 potential respondents. The main outcome measure was COVID-19 VBD acceptance willingness. Binary logistic regression analysis was conducted to rationalize the study's objectives. The pooled COVID-19 booster vaccine acceptance rate was 70.0 % (95 % confidence Interval [CI]: 67─73) among Bangladeshi people. An analysis of binary logistic regression revealed that, out of 14 potential factors, "efficacy", "repeated immunity", "communication", and "trust" showed highly significant positive association (adjusted odds ratio [aOR ] = 2.151 95 % CI: 1.391─ 3.508, aOR = 2.033 95 % CI: 1.299─ 3.181, and aOR = 2.552 95 % CI: 1.557─4.183 respectively, p<0.01), and "equal safety", "risk-benefit ratio" and "community protection" had significant positive association (aOR = 1.739 95 % CI: 1.070─2.825, aOR = 1.712 95 % CI: 1.116─2.627, and aOR = 1.628 95 % CI: 1.395─0.998, p<0.05) with VBD acceptance. However, post-vaccination "side effects" showed significant negative (aOR = 0.393 95 % CI: 0.237─0.674, p<0.01) associations with VBD acceptance. The odds of accepting the COVID-19 vaccine booster was found 1.26, and it was found insignificant (p>0.05) in the Chi-squared test. Bangladeshi people expressed a moderately high level response to COVID-19 VBD acceptance. A positive attitude towards the COVID-19 VBD is an outcome of this study, regardless of the circumstances, as far as safety, efficacy, perceived health benefits, communication, trust, and community resistance are concerned. Post-vaccination side effects fear was the primary reason for booster dose skepticism as well as a barrier to administering booster shots. The confidence in COVID-19 VBD will be boosted when mass people are effectively communicated and vaccine's data become more available publicly.

Multi-dimensional potential factors influencing COVID-19 vaccine booster acceptance and hesitancy among university academic community in Bangladesh: A cross-sectional comparative study

BACKGROUND AND AIMS

Vaccination is the most powerful public health intervention proven to be safe and effective in the battle against the coronavirus disease-2019 (COVID-19) pandemic. Despite the potential therapeutic benefits of primer vaccine dosage regimens, public perceptions of COVID-19 vaccine booster dose (VBD) acceptance and hesitancy vary among various sub-group populations. This study investigates COVID-19 vaccine booster dose acceptance and compares the multi-dimensional potential factors influencing VBD acceptance and hesitancy among university teachers and the student community in Bangladesh.

METHODS

This web-based cross-sectional study employed an anonymous, validated, and self-administered questionnaire. The questionnaire items were adopted from a theoretical analysis of the recent relevant literature. The questionnaire was deployed in an on-line-enabled format (Google form) and conveniently distributed to 685 teachers and 990 students between 15th June, 2022 and 15th August, 2022 which resulted in the participation of 1250 (505 teachers vs.745 students) total respondents (response rate 73.72% vs. 75.25%) from various universities in Bangladesh. A non-parametric analytical tool (binary logistic regression) was applied to rationalize the study objectives and a Chi-squared test was performed to estimate the booster- hesitant risky group.

RESULTS

The pooled COVID-19 vaccine booster dose acceptance rates were 84.6% (95% CI 81.5─87.7) and 67.2% (95% CI 63.8─70.6) for teachers and students in the university academic community, respectively. In employing a binary logistic regression, this study revealed that out of twelve (12)multi-dimensional key predictors, "equal safety", "risk-benefit ratio", and "variant control" had a significant positive association with VBD acceptance in both sets (p = 0.000, p = 0.000, and p = 0.005, respectively). Varied effects were found for several predictors; post-vaccination "side effects" had a significant negative association (p = 0.020) and "community protection" had significant positive association (p = 0.034) with vaccine booster dose acceptance in the teachers community while these variables were insignificant in the students cohort. "Trust" had a highly significant positive association (p = 0.000);"communication" and "academic attainment" had significant positive associations (p = 0.033 and 0.024, respectively) with VBD acceptance in the students cohort, while these predictors were insignificant in the teachers community. Women were more likely to receive a third dose of the vaccine (OR = 1.4 vs. 0.9 between teacher and student model); however, no significant association between gender and booster vaccine acceptance was found in a comparative Chi-squared model. Therefore, statistically, the booster vaccine-hesitant risky group was not found to implicate the massive booster vaccine drive among the university academic community.

CONCLUSIONS

COVID-19 booster vaccine acceptability among the student cohort was slightly lower than pre-roll-out intent. The teacher community was more inclined to get booster vaccinated. Moreover, differences were found between the multi-dimensional potential factors associated with VBD acceptance among teachers and students in university settings. This study explicitly confirmed positive attitudes toward the safety, health benefits, and variants control of the COVID-19 VBD under any circumstances. Post-vaccination side effect concern was found to be a barrier to administering booster shots and a reason for booster skepticism. Tailored communication and health education interventions need to be adopted to improve the public awareness of booster vaccine consequences, and limit booster skepticism.

Temporal dynamics and fatality of SARS-CoV-2 variants in Bangladesh

Background and Aims

Since the beginning of the SARS-CoV-2 pandemic, multiple new variants have emerged posing an increased risk to global public health. This study aimed to investigate SARS-CoV-2 variants, their temporal dynamics, infection rate (IFR) and case fatality rate (CFR) in Bangladesh by analyzing the published genomes.

Methods

We retrieved 6610 complete whole genome sequences of the SARS-CoV-2 from the GISAID (Global Initiative on Sharing all Influenza Data) platform from March 2020 to October 2022, and performed different in-silico bioinformatics analyses. The clade and Pango lineages were assigned by using Nextclade v2.8.1. SARS-CoV-2 infections and fatality data were collected from the Institute of Epidemiology Disease Control and Research (IEDCR), Bangladesh. The average IFR was calculated from the monthly COVID-19 cases and population size while average CFR was calculated from the number of monthly deaths and number of confirmed COVID-19 cases.

Results

SARS-CoV-2 first emerged in Bangladesh on March 3, 2020 and created three pandemic waves so far. The phylogenetic analysis revealed multiple introductions of SARS-CoV-2 variant(s) into Bangladesh with at least 22 Nextstrain clades and 107 Pangolin lineages with respect to the SARS-CoV-2 reference genome of Wuhan/Hu-1/2019. The Delta variant was detected as the most predominant (48.06%) variant followed by Omicron (27.88%), Beta (7.65%), Alpha (1.56%), Eta (0.33%) and Gamma (0.03%) variant. The overall IFR and CFR from circulating variants were 13.59% and 1.45%, respectively. A time-dependent monthly analysis showed significant variations in the IFR (p = 0.012, Kruskal-Wallis test) and CFR (p = 0.032, Kruskal-Wallis test) throughout the study period. We found the highest IFR (14.35%) in 2020 while Delta (20A) and Beta (20H) variants were circulating in Bangladesh. Remarkably, the highest CFR (1.91%) from SARS-CoV-2 variants was recorded in 2021.

Conclusion

Our findings highlight the importance of genomic surveillance for careful monitoring of variants of concern emergence to interpret correctly their relative IFR and CFR, and thus, for implementation of strengthened public health and social measures to control the spread of the virus. Furthermore, the results of the present study may provide important context for sequence-based inference in SARS-CoV-2 variant(s) evolution and clinical epidemiology beyond Bangladesh.

Predictors of receiving COVID-19 vaccine among adult population in Iran: an observational study

BACKGROUND

Vaccination is one of the best ways to stop the transmission of coronavirus disease 2019 (COVID-19). In this regard, uunderstanding the features related to the intention of different populations to receive the COVID-19 vaccine is essential for an effective vaccination program. This study aimed to investigate the vaccination intention predictors in the general adult population of Iran.

METHODS

A cross-sectional, web-based survey was conducted on social networks, including Telegram, WhatsApp, LinkedIn, Instagram, and Facebook. Multinomial logistic regression models were used to investigate predictors associated with the intention to receive COVID-19 vaccines, including sociodemographic characteristics, trust, worry, sources of information, and conspiracy beliefs. The main outcomes included unwillingness, undecidedness, and intention to receive the COVID-19 vaccine.

RESULTS

Out of 780 respondents, 481 (61.6%) reported an intention to be vaccinated, 214 (27.4%) expressed their undecided status, and 85 (10.9%) reported unwillingness to receive any type of COVID-19 vaccine. A higher age (OR undecided = 0.97, 95% CI (0.96-0.99)), (OR unwilling = 0.97, 95% CI (0.95-0.99)); exposure with COVID-19 (OR unwilling = 0.82, 95% CI (0.76-0.89)), (OR undecided = 0.87, 95% CI (0.83-0.93)) were positively associated with vaccination intentions. No/low trust in vaccines, institutions, concerns about the future of the pandemic, and conspiracy beliefs were strongly and negatively associated with COVID-19 vaccination intentions.

CONCLUSION

Most Iranians intended to get a COVID-19 vaccine. Higher vaccine acceptance needs to consider demographic features, exposure history, confidence in vaccines, trust in institutions, concerns, and conspiracy beliefs of people.

COVID-19 vaccine acceptance and its drivers among Pakistani population

Background & Objective

COVID-19 vaccine has become available within a record time but mere availability will not control the pandemic. High vaccine acceptance is required. The objective was to determine COVID-19 vaccine acceptance and its associated factors among Pakistani population.

Methods

An online survey using google form, was conducted from January 31st to February 9th, 2021 before the start of the mass vaccination in Pakistan. The questionnaire had questions about demographics plus vaccine hesitancy. We received a total of 1156 responses. Data was analyzed using STATA version 14. We employed descriptive statistics and chi square test.

Result

A total of 1156 responses were received. 65% were male and 35% female. Only 6% were uneducated. Thirty percent had tested positive for COVID-19 earlier. Forty-six percent of the respondents would take (acceptance) a vaccine if available. Forty-eight percent and 45% were confident in using USA/UK and Chinese vaccine respectively. Gender and marital status was statistically significantly associated with vaccine acceptance. Concerns about the side effects were 55% while for efficacy it was 69%. Twenty-three percent were concerned about the permissibility of the vaccine on religious grounds.

Conclusion

Gender and marital status was significantly associated with vaccine acceptance. Forty-six percent respondents were willing to take the vaccine. Among the vaccine hesitant group, respondents were worried about the side effects, safety and religious permissibility of vaccine. Policy makers and all the relevant stakeholders should consider low vaccine acceptance as a major bottleneck and should devise strategies to address this major issue in the fight against COVID-19.

Perceptions around COVID-19 and vaccine hesitancy: A qualitative study in Kaski district, Western Nepal

Burgeoning morbidity and mortality due to COVID-19 pandemic including the peaks in outbreaks due to different variants have attracted global attention. Although the development and rolling out of vaccines have been impressive, low- and middle-income countries suffer from a double burden: (1) lack of adequate vaccines; and (2) low vaccine uptake (vaccine hesitancy). The main objective of this study was to explore perceptions around COVID-19 and vaccine hesitancy among urban and rural population in Western Nepal. A qualitative study was conducted in six urban wards of Pokhara municipality and four rural municipalities in Kaski district of Nepal. A semi-structured interview guide was used to interview participants who were selected purposively to explore the perceived burden of COVID-19 pandemic, roles, and contributions of vaccine. Nineteen interviews were conducted by telephone following a government recommendation to avoid face-to-face meetings. Audio-recorded interviews were thematically analysed after transcription and translation into English. COVID-19 is a major (public) health concern and affects people at an individual, societal and national level. People dreaded its health hazards and consequences and seemed to be compliant with public health measures such as maintaining social distance, wearing masks and maintaining hygiene. Vaccine was considered to be a major intervention to fight the pandemic, nonetheless, the rationale and benefits of vaccines were blemished by the perceived lack of the vaccine's effectiveness, duration of protection, and its potential side-events. Expedited development of vaccine was embraced with suspicion that vaccine may have incurred compromise in quality. Science and rationale behind vaccine were smeared by misinformation and clearly counteracting the misinformation were deemed critical. Providing information about vaccines through government entities (who are trusted) and respected individuals may engender trust and uptake of vaccine. Fighting off misinformation of COVID-19 is critical to curb the course of pandemic. Increased attention towards monitoring and investing in legitimacy of information and offering information through trusted sources can help improve the vaccine coverage.

Comparison of vaccine hesitancy during the low and high points of COVID-19 in a population under international sanctions: A longitudinal mixed-methods study in Iran

Introduction

Along with the challenges of COVID-19 vaccine supply in low-income countries, vaccine hesitancy was another problem for the health system. The aim of this study was to deeply understand the challenges of vaccine acceptance, the vaccination process, and to compare the affecting vaccine acceptance in the high and low points of the epidemic in Iran.

Methods

In the qualitative part of this mixed-methods study, content analysis was used to investigate experiences and perceptions about COVID-19 vaccination in four groups. In the quantitative study, in March 2021 (low point), and on August 1, 2021 (high point), two population-based cross-sectional studies were performed in Tehran and its rural, with sample sizes of 1,200 and 1,872 people aged over 18 years, respectively. Multinomial (polytomous) logistic regression was used to determine the factors affecting hesitation and unwillingness to receive the vaccine.

Results

Disbelief in vaccine safety, vaccine distrust, ignorance and confusion, and inadequate facilities were the common reasons extracted in the two qualitative studies. At the low and high points of the epidemic, vaccine acceptance was 83.6% (95% CI: 81.3-85.9) and 65.8% (95% CI: 65.8-71.0), respectively. Residence in rural areas, (Odds Ratio: 0.44, p = 0.001), being a student (Odds Ratio: 0.41, p = 0.011), housewives (Odds Ratio: 0.63, p = 0.033), illiteracy (Odds Ratio: 4.44, p = 0.001), and having an underlying disease (Odds Ratio: 4.44, p = 0.001) were factors affecting on vaccine acceptance.

Discussion

Counter-intuitively, acceptance did not increase at the peak of epidemic. The presence of obstacles, such as increased distrust in the effectiveness of vaccines due to the occurrence of multiple peaks in different vaccinated countries, as well as the influence of the media, anti-vaccine campaigns, and lack of proper communication about risks caused more hesitation. More investigation to understand how people accept or reject vaccine and its long term consequences is recommended.

Impact of COVID-19 Vaccination on Seroprevalence of SARS-CoV-2 among the Health Care Workers in a Tertiary Care Centre, South India

Global vaccine development efforts have been accelerated in response to the devastating COVID-19 pandemic. The study aims to determine the seroprevalence of SARS-CoV-2 IgG antibodies among vaccine-naïve healthcare workers and to describe the impact of vaccination roll-out on COVID-19 antibody prevalence among the health care centers in tertiary care centers in South India. Serum samples collected from vaccinated and unvaccinated health care workers between January 2021 and April 2021were subjected to COVID-19 IgG ELISA, and adverse effects after the first and second dose of receiving the Covishield vaccine were recorded. The vaccinated group was followed for a COVID-19 breakthrough infection for a period of 6 months. Among the recruited HCW, 156 and 157 participants were from the vaccinated and unvaccinated group, respectively. The seroprevalence (COVID-19 IgG ELISA) among the vaccinated and unvaccinated Health Care Workers (HCW) was 91.7% and 38.2%, respectively, which is statistically significant. Systemic and local side-effects after Covishield vaccination occur at lower frequencies than reported in phase 3 trials. Since the COVID-19 vaccine rollout has commenced in our tertiary care hospital, seropositivity for COVID-19 IgG has risen dramatically and clearly shows trends in vaccine-induced antibodies among the health care workers.

COVID-19 Vaccine Hesitancy and its Reasons in Addis Ababa, Ethiopia: A Cross-Sectional Study

Background

Coronavirus disease (COVID-19) vaccine hesitancy becomes the major bottleneck to the global healthcare system in minimizing the spread of the virus. This study aimed at assessing COVID-19 vaccine hesitancy and its reasons among residents of Addis Ababa, Ethiopia.

Methods

A community-based cross-sectional survey was conducted between May 16 to 29, 2021 in purposively selected four districts of Addis Ababa, Ethiopia. A structured questionnaire was developed and then designed on Google Forms platforms to collect data from study participants after obtaining a verbal consent form. A total of 422 study participants were included in the survey. Data were entered into Microsoft Excel and then exported to the Statistical Package for the Social Sciences (SPSS) version 25 for analysis.

Results

Face masks and alcohol hand rub/ sanitizer are used by 50. 7 and 24.9% of respondents when required. COVID-19 was thought to have been generated by humans by a substantial percentage of study participants (38.2%). About half (50.7%) and 24.9% of respondents use face masks and alcohol hand rub/sanitizer always when it is required, respectively. A large number of study participants (38.2%) believed that origin of COVID-19 is man-made. Overall, 242 (57.4%) of study participants reported COVID-19 vaccine hesitancy. Fear of vaccine side effects (49.6%) was the most common reason for hesitancy. Doubt about its effectiveness (33.9%), not having enough information about the COVID-19 vaccine, preferring another way of protection, and unreliable of the vaccine (due to its short development period) were also the most frequently mentioned reasons for not receiving the COVID-19 vaccine.

Conclusions

COVID-19 vaccine hesitancy rate was high in Addis Ababa, Ethiopia during the study period. Fear of side effects, doubts about its effectiveness, and not having enough information about the COVID-19 vaccine were major reasons for hesitancy. Continuous awareness creation to the community on the importance of vaccination is warranted by health professionals and healthcare cadres.

Social media and attitudes towards a COVID-19 vaccination: A systematic review of the literature

Background

Vaccine hesitancy continues to limit global efforts in combatting the COVID-19 pandemic. Emerging research demonstrates the role of social media in disseminating information and potentially influencing people's attitudes towards public health campaigns. This systematic review sought to synthesize the current evidence regarding the potential role of social media in shaping COVID-19 vaccination attitudes, and to explore its potential for shaping public health interventions to address the issue of vaccine hesitancy.

Methods

We performed a systematic review of the studies published from inception to 13 of March2022 by searching PubMed, Web of Science, Embase, PsychNET, Scopus, CINAHL, and MEDLINE. Studies that reported outcomes related to coronavirus disease 2019 (COVID-19) vaccine (attitudes, opinion, etc.) gathered from the social media platforms, and those analyzing the relationship between social media use and COVID-19 hesitancy/acceptance were included. Studies that reported no outcome of interest or analyzed data from sources other than social media (websites, newspapers, etc.) will be excluded. The Newcastle Ottawa Scale (NOS) was used to assess the quality of all cross-sectional studies included in this review. This study is registered with PROSPERO (CRD42021283219).

Findings

Of the 2539 records identified, a total of 156 articles fully met the inclusion criteria. Overall, the quality of the cross-sectional studies was moderate - 2 studies received 10 stars, 5 studies received 9 stars, 9 studies were evaluated with 8, 12 studies with 7,16 studies with 6, 11 studies with 5, and 6 studies with 4 stars. The included studies were categorized into four categories. Cross-sectional studies reporting the association between reliance on social media and vaccine intentions mainly observed a negative relationship. Studies that performed thematic analyses of extracted social media data, mainly observed a domination of vaccine hesitant topics. Studies that explored the degree of polarization of specific social media contents related to COVID-19 vaccines observed a similar degree of content for both positive and negative tone posted on different social media platforms. Finally, studies that explored the fluctuations of vaccination attitudes/opinions gathered from social media identified specific events as significant cofactors that affect and shape vaccination intentions of individuals.

Interpretation

This thorough examination of the various roles social media can play in disseminating information to the public, as well as how individuals behave on social media in the context of public health events, articulates the potential of social media as a platform of public health intervention to address vaccine hesitancy.

What is driving unwillingness to receive the COVID-19 vaccine in adult Bangladeshi after one year of vaccine rollout? Analysis of observational data

Objective

The present study aimed to (1) assess the prevalence of COVID-19 vaccine unwillingness and (2) identify the factors associated with vaccine unwillingness.

Methods

This cross-sectional study analyzed data of 2633 Bangladeshi adults. Descriptive analysis was performed to compute the prevalence of vaccine unwillingness by the participants' sociodemographic characteristics. Multiple logistic regression analyses were performed to compute Adjusted Odds Ratios (AORs) with vaccine unwillingness as a dependent variable and sociodemographic characteristics as predictor variables for vaccine unwillingness.

Results

Overall, 27.4% respondents showed unwillingness to receive the COVID-19 vaccine. Regression model suggested that groups with significantly higher odds of vaccine unwillingness were found to be participants aged 18-25 years (AOR= 3.41, CI= 1.71-6.80), Muslim (AOR= 1.81, CI= 1.21-2.71), participants with higher secondary education (AOR= 3.12, CI= 1.73-5.63), unemployed (AOR= 8.79, CI= 5.42-14.26), participants with monthly household income < □ 15000 (AOR= 4.03, CI= 2.51-6.47), residents of a semi-urban setting (AOR= 1.43, CI= 1.01-2.03), participants affiliated with opposition parties (AOR= 2.82, CI= 1.89-4.21), and participants who did not report that they or their family members tested positive for COVID-19 (AOR= 4.32, CI= 3.08-6.07).

Conclusion

The study findings suggested that a certain vaccine literacy campaign targeting semi-urban, low-income, and low-educated Bangladeshi is warranted to ensure the widespread uptake of COVID-19 vaccines in Bangladesh.

COVID-19 Vaccine Hesitancy

Improving access to accurate information on vaccines and vaccination, increasing trust in reliable information sources, and counteracting misinformation can go a long way toward improving vaccination decision making.
