Knowledge and Attitude Towards Second COVID-19 Vaccine Dose Among Health Professionals Working at Public Health Facilities in a Low Income Country

Understanding the COVID-19 vaccine uptake, acceptance, and hesitancy in Ethiopia and Tanzania: a scoping review

Background

The development and implementation of COVID-19 vaccines have been a breakthrough in controlling the pandemic. However, the vaccination coverage in most low-income countries remains very low due to critical vaccine shortage and profound hesitancy. In this scoping review, we aimed to assess COVID-19 vaccine uptake, acceptance, and hesitancy in Ethiopia and Tanzania.

Methods

The search was made in PubMed, Scopus, Embase, and Web of Science. Only original research articles focusing on vaccine acceptance and hesitancy were included. The studies selected for a full read were analysed using a thematic analysis approach.

Findings

A total of 76 articles were included in the study, with 74 of them coming from Ethiopia. The study found an increasing trend in vaccine uptake over time. However, there was also an increase in hesitancy and a decline in willingness to receive the vaccine. The willingness to receive the COVID-19 vaccine in Ethiopia ranged from 18.5 to 88%. The main reasons for "vaccine hesitancy" included fear of side effects, concerns about long-term safety, doubts about vaccine effectiveness, lack of information, vaccine fast-tracking, and religious beliefs. The study also found that younger individuals, females, and pregnant women were less willing to receive the vaccine. The adverse events reported among vaccinated individuals were mostly mild. Most of the studies operationalised vaccine acceptance-hesitancy as dichotomous variables. However, the historical, political, and socio-cultural context in which vaccine acceptance and hesitancy occur was not given any attention. While there is a good amount of data from Ethiopia describing patterns of vaccine acceptance and hesitancy among different populations over time, there is limited information from Tanzania due to the late arrival of the vaccine and limited published articles.

Conclusion

We have observed a paradox involving two seemingly conflicting trends: an increase in vaccination rates/coverage and "anti-vax." Most studies have simplified vaccine acceptance-hesitancy as an "either-or" incident, without considering its dynamic nature and occurrence within a broader political, social, and cultural context. Therefore, it is crucial to explore approaches that can enhance our understanding of the vaccine acceptance-hesitancy phenomenon, in order to improve vaccine trust and uptake.

Factors associated with COVID-19 vaccine uptake among health professionals in Debre Markos town public health facilities, Northwest Ethiopia

Globally, the COVID-19 pandemic has significantly increased morbidity and mortality. Health professionals are at the frontline of COVID-19 pandemic exposure and are identified as a priority target group that needs to receive COVID-19 vaccines. Data on Ethiopian healthcare workers' use of the COVID-19 vaccine and associated factors, however, are scarce. Using a simple random sampling method, 398 health professionals were recruited through an institutional-based cross-sectional study design. Health professionals working in Debre Markos town public health facilities filled out a self-administered questionnaire that had been pretested to obtain the data. Then, the data were entered into Epi data version 4.2; and analyzed by SPSS 25. Descriptive statistics and multivariable logistic regression analysis were computed after model assumptions were checked. The adjusted odds ratio with 95% CI was calculated and statistical significance was declared at P-value < 0.05 after model adequacy was checked using the Hosmer-Lemeshow test. The uptake of the COVID-19 vaccine among health professionals was 61.56% (95% CI: 56.67%, 66.23%). Factors associated with the uptake of the COVID-19 vaccine were age > = 35 years (AOR: 4.39, 95% CI: 1.89, 10.19), having a higher income (>9056 Birr) (AOR: 1.79, 95% CI: 1.03, 3.10), who practiced COVID-19 Prevention methods (AOR: 2.39, 95% CI: 1.51, 3.77), Adulthood previous other immunization histories (AOR: 1.63, 95% CI: 1.15, 2.56) and having a chronic disease (AOR:1.90,95% CI: 1.07, 3.74). This study revealed that the uptake of the COVID-19 vaccine was low. Age > = 35 years, having a higher income, who practiced COVID-19 prevention methods, having adulthood previous immunization histories, and having chronic disease were statistically significantly identified factors for COVID-19 vaccine uptake. Therefore, policymakers and health managers should think about the requirement of immunization of healthcare workers and develop plans for administering the COVID-19 vaccine.

Determinants of COVID-19 Vaccine Uptake Among Health Workers and General Public in Tanzania

Background

Insufficient knowledge about COVID-19 and low socioeconomic status have been associated with distrustful attitudes towards vaccination against COVID-19.

Objective

The aim of this study was to explore determinants of COVID-19 vaccine uptake among the general population and health workers.

Methods

A cross sectional study was conducted in 16 councils which included; Milele, Mpanda, Newala, Simanjiro, Nanyumbu, Muleba, Longido, Ulanga, Igunga, Mbulu, Karatu, Mufindi, Mvomero, Kilolo and Tabora Town. A total of 427 health care workers and 1,907 individuals were sampled from health facilities and households. Structured questionnaires were used to collect the required information.

Results

Although the majority (93.2%) of health workers were vaccinated, 35.4% perceived their risk of getting COVID-19 infection as high. Self-reported uptake of COVID-19 vaccine was 42.4% among the general population. Significantly low proportion of the general population in Mufindi district council (7.5%) were vaccinated against COVID-19. Health workers' knowledge and perception on COVID-19 vaccination did not vary with socio-demographic factors. Among the general population, those who were separated/divorced (ARR: 0.8: 95% CI; 0.7 to 0.9), those who attained primary level of education (ARR: 0.8: 95% CI; 0.7 to 0.9), self-employed (ARR: 0.8: 95% CI; 0.7 to 0.9) and unemployed (ARR: 0.7: 95% CI; 0.6 to 0.8) were less likely to be vaccinated against COVID-19. Having positive attitude (ARR: 1.2: 95% CI; 1.1 to 1.5) and perception (ARR:1.8: 95% CI; 1.5 to 2.2), and knowledge on COVID-19 prevention (ARR: 3.0: 95% CI; 2.1to 4.4) increased the likelihood COVID-19 vaccine uptake. Prior experience of vaccination against other diseases (ARR:1.2: 95% CI; 1.0 to1.3), having history of chronic diseases (ARR:1.3: 95% CI; 1.2 to 1.4) and a family member who died of COVID-19 (ARR:1.3: 95% CI; 1.1to1.4) were also determinants of COVID-19 vaccine uptake.

Conclusion

Uptake of COVID-19 vaccine among the general population was significantly low among individuals with primary level of education, self-employed, unemployed, and those who were divorced or separated. Individuals with comprehensive knowledge on COVID-19 vaccination, those with positive attitude and perception on COVID-19 vaccination, having history of chronic diseases, prior vaccination against other diseases, and having a family member who succumbed to COVID-19 increased the likelihood COVID-19 vaccine uptake among the general population. Provision of health education and implementation of socio-behavioural communication change interventions are necessary to equip the general population with appropriate knowledge to transform their negative attitude and perception on COVID-19 vaccination.

Healthcare professionals' perception and COVID-19 vaccination attitudes in North-Western Ghana: A multi-center analysis

INTRODUCTION

The novel coronavirus SARS-CoV-2 causes Coronavirus Disease 2019 (COVID-19). Vaccination has been identified as one of the most effective strategies for combating COVID-19. Positive perceptions and attitudes of HCPs towards the COVID-19 vaccination are essential to vaccine uptake and adherence. However, the perceptions and attitudes of HCPs towards the COVID-19 vaccination remain largely unexplored. We therefore assessed healthcare professionals' perceptions, attitudes, and predictors of their attitudes towards COVID-19 vaccination in the Wa Municipality, Upper West Region of Ghana.

METHODS

In 2023, from January 16th to February 28th, we administered a multi-centre e-survey to a cross-section of 403 healthcare professionals in Wa Municipality of the Upper West Region, Ghana. We used STATA version 13 to analyze the data. Frequencies, percentages, and composite scores were used to assess perceptions and attitudes towards the COVID-19 vaccination. Hierarchical binary logistic regression modeling was then used to determine the predictors of attitudes towards the COVID-19 vaccination.

RESULTS

The healthcare professionals had positive perceptions [6.00; IQR = 4.00-7.00] and attitudes [5.00; IQR = 4.00-5.00] towards theCOVID-19 vaccination. Positive perception [aOR = 1.81; 95% CI = 1.14-2.87, p < 0.05], female sex [aOR = 0.58; 95% CI = 0.35-0.97, p < 0.05], marital status [aOR = 1.94; 95% CI = 1.20-3.12; p < 0.01], having a bachelor's degree or higher [aOR = 2.03; 95% CI = 1.01-4.12; p < 0.05], and working in the Wa North sub-Municipal area [aOR = 0.22; 95% CI = 0.05-0.96; p < 0.05] were statistically significantly associated with attitudes towards COVID-19 vaccination.

CONCLUSION

The healthcare professionals' perceptions and attitudes towards the COVID-19 vaccination were positive but suboptimal. We recommend regular education on COVID-19 vaccine benefits, safety, and efficacy. Enabling the work environment and addressing vaccine availability and accessibility for healthcare professionals should also be prioritized. These measures should particularly focus on female, single healthcare professionals who possess below a bachelor's degree and are working in the Wa North sub-municipal area.

Knowledge and attitude towards Covid-19 vaccine in Ethiopia: Systematic review and meta-analysis

The biggest threat to the effectiveness of vaccination initiatives is a lack of information about and trust in immunization. This study aimed to determine the prevalence of knowledge of and positive attitudes toward the COVID-19 vaccine in Ethiopia. PubMed, Web of Science, Google Scholar, EMBASE, and the Ethiopian University online library were searched. To look for heterogeneity, I² values were computed and an overall estimated analysis was carried out. Although 2108 research articles were retrieved, only 12 studies with a total of 5,472 participants met the inclusion criteria for this systematic review and meta-analysis. The pooled estimates of participants with good knowledge of and positive attitudes toward the COVID-19 vaccine were found to be 65.06% (95% CI: 56.69-73.44%; I² = 82.3%) and 60.15% (95% CI: 45.56-74.74%; I² = 89.4%), respectively, revealing that there is a gap in knowledge of and positive attitudes toward the COVID-19 vaccine in Ethiopia. A holistic and multi-sectoral partnership is necessary for a successful COVID-19 vaccination campaign.

Knowledge, attitude, and practices of front line health workers after receiving a COVID-19 vaccine: a cross-sectional study in Pakistan

BACKGROUND

Globally, there is an increased risk of COVID-19 infection among front-line health workers (FHW). This study aimed to evaluate the knowledge, attitude, and practices of FHW of Pakistan after receiving the COVID-19 vaccine.

METHODS

A population web-based survey on COVID-19 vaccine was conducted on 635 FHW in Pakistan between April 15, 2021, and July 15, 2021. The survey focused on four main sections consisting of socio-demographic data, knowledge, attitude, and practices after receiving the COVID-19 vaccine. The data was analyzed on SPSS. p < 0.05 was considered significant.

RESULTS

Overall, 60% of FHW were nervous before getting vaccinated, with the leading reason to get vaccinated being their concern to protect themselves and their community (53.4%). A majority of FHW had fear about the unseen side effects of the COVID-19 vaccine (59.7%) used in Pakistan, with the most common side effect reported as soreness at the injection site (39%). It has been noted that almost all of the FHW observed preventive practices after getting vaccinated. The results showed that married respondents had favorable practices towards COVID-19 vaccines (B = 0.53, p < 0.01) (B, unstandardized regression coefficient). It was also found that more informational sources (B = 0.19, p < 0.01), higher knowledge of vaccination (B = 0.15, p < 0.001), and favorable attitude toward vaccine (B = 0.12, p < 0.001) significantly predicted favorable practices toward COVID-19 vaccination.

CONCLUSION

The findings reflect that FHW, though they were worried about its side effects, have good knowledge and a positive attitude after getting the COVID-19 vaccine. This study is significant as the FHWs are a symbol for guidance, a reliable source of information, and an encouraging means of receiving COVID-19 vaccine for the general public. This study also reported that post-vaccination side effects were mild which will aid in reducing the vaccine hesitancy among the general Pakistani population.

Vaccinated Healthcare Workers' Adherence to COVID-19 Prevention Measures and Associated Factors in Northwest Ethiopia: A Facility-Based Cross-Sectional Study

Background

The initial response to coronavirus disease 2019 (COVID-19) was non-pharmaceutical interventions (NPIs). Long-term protection against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection does not appear to be possible by either infection or vaccination. Thus, traditional herd immunity seems impossible. In addition to increasing vaccination rates, NPIs may be needed.

Methods

A facility-based cross-sectional study was conducted among vaccinated healthcare workers. The study took place from July 15 to August 15, 2022. A self-administered questionnaire was used for data collection. In a multivariable logistic regression model, a p-value of less than 0.05 was considered statistically significant.

Results

Four hundred eleven healthcare workers were included in the study. Sixty percent of participants were fully vaccinated. After vaccination, 10.2% of respondents reported infection with SARS-CoV-2. The study showed that 49.4% of participants had a good knowledge of the efficacy and safety of vaccines against SARS-CoV-2. In this study, 36% of individuals adhered well to the COVID-19 prevention strategies. Good knowledge of the efficacy and safety of SARS-CoV-2 vaccines (AOR = 1.69, 95% CI: 1.03-2.78) increased the odds of implementing preventive measures. Healthcare workers who perceived a low and medium risk of SARS-CoV-2 infection after vaccination and who were knowledgeable about SARS-CoV-2 breakthrough infections were less likely to follow preventive measures.

Conclusion

The knowledge of healthcare workers regarding the efficacy and safety of vaccines against SARS-CoV-2 was comparable. However, a large proportion of healthcare workers poorly adhered to prevention practices. Therefore, to reduce the risk of SARS-CoV-2 infection among healthcare professionals, prevention strategies must be continuously evaluated and awareness of the need for preventive measures must be raised even after vaccination.

Knowledge, attitude, and intention to accept COVID-19 vaccine among patients with chronic diseases in southern Ethiopia: Multi-center study

Background

Most of the COVID-19 fatal cases and severe illnesses like acute respiratory distress syndrome occur in older adults and other people who have underlying medical comorbidities. Understanding patients with chronic disease' knowledge, attitudes, and intention to take the COVID-19 vaccine and related factors are necessary to control the mortality of COVID-19 infection. Therefore, this study aimed to assess knowledge, attitudes, and intention to take the COVID-19 vaccine among patients with chronic disease in Southern Ethiopia.

Methods and materials

A facility-based cross-sectional study was conducted among 409 patients with chronic diseases having a follow-up at the hospitals of the Southern region of Ethiopia from November 14, 2021, to December 24, 2021. A structured, interviewer-administered questionnaire was used to collect data. Bivariate and multivariable logistic regression was conducted to show the association of variables with knowledge, attitude, and intention to take the COVID-19 vaccine. The associations of variables were declared with the use of a 95% CI and P-value < 0.05.

Results

Overall, 79.2, 70.9, and 58.2% of participants had good knowledge, favorable attitude, and intent to take the COVID-19 vaccine, respectively. Age ≥49 years old (AOR = 1.643; 95% CI = 1.008-3.060) and college and above level of education (AOR = 3.002; 95% CI = 1.897-5.021) were found to be significantly associated with knowledge about COVID-19 vaccine. College and above level of education (AOR = 1.510; 95% CI = 1.002-3.975) and good knowledge (AOR = 3.560; 95% CI = 1.481-6.120) were found to be significantly associated with intention to take COVID-19 vaccine.

Conclusion and recommendation

Intention to take the COVID-19 vaccine was low among patients with chronic diseases to achieve herd immunity. Therefore, a holistic and multi-sectoral partnership is necessary for a successful COVID-19 vaccination campaign. Further health education and communication are very crucial methods to improve vaccine acceptance and lastly to achieve herd immunity.

Mitigating COVID-19 Risk and Vaccine Hesitancy Among Underserved African American and Latinx Individuals with Mental Illness Through Mental Health Therapist-Facilitated Discussions

Background

Underserved ethnic minorities with psychiatric disorders are at an increased risk of COVID-19. This study aims to examine the effectiveness of one-to-one counseling on COVID-19 vaccination and vaccination readiness among underserved African American and Latinx individuals with mental illnesses and adult caregivers of children with mental illness.

Methods

Through an academic-community partnered collaboration, a multidisciplinary and culturally sensitive training on COVID-19 was co-developed and delivered to 68 therapists from January to March 2021. Mental health clients and their caregivers were recruited to participate in pre- and post-intervention surveys to evaluate the impact of the intervention on their perceptions of COVID-19 public health guidelines, testing, and vaccination. Mental health therapists delivered four lessons of the COVID-19 educational intervention with 254 clients from March to June 2021, when vaccine availability was widely available. Of those clients, we collected 180 baseline and 115 follow-up surveys. The main outcome was the uptake in COVID-19 vaccine.

Results

There was a positive shift in participant vaccine acceptance and receptivity. Pre-intervention survey shows that only 56% of adult clients and 48% of caregivers had indicated a likelihood of getting the vaccine for themselves at baseline. Post-intervention documented that more than 57% of each group had been vaccinated, with another 11–15% of the unvaccinated individuals reporting that they were somewhat or very likely to get the vaccine.

Conclusion

This study demonstrated that multidisciplinary academic-community and theoretical-based educational intervention delivered by mental health therapists is an effective strategy in increasing COVID-19 vaccine acceptance and reducing the negative impact and disruption that COVID-19 caused in the daily life of mental health patients and caregivers.

Assessing public knowledge, attitudes and determinants of third COVID-19 vaccine booster dose acceptance: current scenario and future perspectives

Background

People with weakened immune systems may not develop adequate protection after taking two doses of the mRNA-combined COVID-19 vaccine. The additional dose may improve the level of protection against Covid-19.

Objectives

Current study aimed to evaluate the knowledge, attitude and determents of third COVID-19 vaccine booster dose acceptance among population in the UAE.

Methods and materials

This is online descriptive cross-sectional community-based study conducted among the students and faculty of Ajman University from 25 August to 20 October 2021. The questionnaire, which was in the English language, encompassed two sections containing 22 items. Section one gathered the demographic details of the respondents, while Section two used 13 questions to evaluate the respondents’ knowledge of and attitude to the third COVID-19 vaccine booster dose.

Results

614 respondents participated in this study. The average knowledge score was 44.6% with a 95% confidence interval (CI) of [41%, 49%]. Better knowledge scores were observed in postgraduates (OR 4.29; 95% CI 2.28–8.11), employees in the healthcare sector (OR 1.62; 95% CI 1.05–2.51), participants who had relatives infected with the Covid-19 (OR 1.46; 95% CI 1.05–2.02), participants who had infected with Covid-19 (OR 2.21; 95% CI 1.43–3.43) and participants who had received first two doses of the COVID-19 vaccine (OR 2.08; 95% CI 1.40–3.11). The average attitude score was 70.2% with a 95% confidence interval (CI) of [69.2%, 71.2%].

Conclusion

Necessary steps should be taken by the government and public health authorities, in line with the local culture, to increase vaccination acceptance and foster positive attitudes towards the vaccine. A suitable approach to this would be to develop an educational framework that could demonstrate the risks of vaccine avoidance or delay to the general population. Moreover, health authorities should pay more attention to the false information being disseminated across the internet, especially social media. Also, healthcare workers should be trained in vaccinology and virology to make sure that they are able to understand important developments in these fields and convey the findings to their patients.

Knowledge and attitude toward the second round of COVID-19 vaccines among teachers working at southern public universities in Ethiopia

About 1.9 million people in Ethiopia have received a first dose of COVID-19 vaccine, which are given to frontline health care workers and university instructors through a campaign. After healthcare workers, teachers at all levels in Ethiopia are assumed to be at a higher risk of exposure to COVID-19. An institution-based cross-sectional study design was used. Simple random sampling was used to select participants. Data were collected using a structured, self-administered questionnaire. Logistic regression analysis was conducted for all variables, and a p-value < 0.05 at 95% CI was considered statistically significant. Overall, 60.8% and 79.7% of participants had good knowledge of and positive attitudes toward a second round of COVID-19 vaccines, respectively. Age (AOR = 1.51 [95% CI = 1.003–3.63]), profession (AOR = 1.402 [95% CI = 1.107–3.003]), work experience (AOR = 1.509 [95% CI = 1.151–2.283]), and chronic diseases (AOR = 2.142 [95% CI = 1.337–3.092]) were predictor variables for knowledge about the second round of COVID-19 vaccines. Sex (AOR = 1.386 [95% CI = 1.018–2.763]), marital status (AOR = 4.180 [95% CI = 2.397–6.989]), profession (AOR = 1.102 [95% CI = 1.008–3.123]), work experience (AOR = 1.211 [95% CI = 1.029–2.877]), and chronic diseases (AOR = 6.110 [95% CI = 4.892–10.661]) were predictor variables for attitudes toward a second round of COVID-19 vaccines. Generally, knowledge and attitudes toward the second round of COVID-19 vaccines among instructors were low. Thus, health education and communication are very crucial.
