Perceptions and Experiences of COVID-19 Vaccine Side-Effects Among Healthcare Workers in Southern Ethiopia: A Cross-Sectional Study

Adverse events of COVID-19 vaccination during 2021-2022 suppressed by breakfast consumption and favorable sleeping habit among Japanese university students

Introduction

Young adults are hesitant to receive the coronavirus disease 2019 (COVID-19) vaccination owing to concerns regarding adverse events despite the effectiveness of vaccines in preventing SARS-CoV-2 infection-associated serious illness, hospitalization, and death.

Methods

A retrospective cohort study was conducted in Gifu University students receiving the mRNA-1273 vaccine and boosters to elucidate the real incidence of adverse events and factors that prevent them. We examined the adverse events and identified potential risk factors through a self-administered questionnaire on the participants' physical condition after COVID-19 vaccination.

Results

Focal/systemic adverse events were highly frequent among university students after receiving the COVID-19 vaccine; however, there were no life-threatening cases or hospitalizations over two years. A higher number of vaccinations (p < 0.001), female sex (p < 0.001), and lower body mass index (BMI) (p = 0.002) were associated with an increased incidence of adverse events on the day of COVID-19 vaccination or the day after vaccination. Regular breakfast consumption was significantly associated with a decreased incidence of post-vaccination itching (p = 0.019) and abdominal pain and diarrhea (p = 0.042). Sufficient sleep duration was significantly associated with a decreased incidence of post-vaccination abdominal pain and diarrhea (p = 0.042).

Conclusions

High frequency of adverse events of COVID-19 mRNA-1273 among Japanese university students was reported. A higher number of shots, female sex, and lower BMI were associated with a higher incidence of adverse events. Regular breakfast and sufficient sleep were associated with fewer adverse events. This study may provide a possible solution to the worldwide problem of vaccine hesitancy.

Experience and side effects of COVID-19 vaccine uptake among university students: a cross-sectional survey study

Introduction

Many people expressed concern over coronavirus vaccinations' reliability and side effects. This research aimed to assess university students' perceptions and experiences regarding the side effects of the COVID-19 vaccines in Bangladesh.

Method

We conducted an online cross-sectional survey to collect responses from university students vaccinated with any vaccines administered in Bangladesh between November 2021 to April 2022. Bangladeshi university students over the age of 18 and having an internet connection was included in the study. A binary logistic regression analysis along with Pearson's Chi-square test were used to identify COVID-19 vaccine-related side effects predictors after receiving the first dose.

Results

A total of 1,176 participants responded voluntarily to the online study, and most were vaccinated. More than half of the participants received the Sinopharm vaccine (56.5%), while others received Covishield (8.9%), Moderna (7.3%), and Pfizer (5.8%) vaccine. Around 32% of the participants reported side effects after receiving the first dose of the vaccine, including pain and edema (78.4%), body temperature (20.3%), and headache (14.5%), while a few experienced allergy, anxiety, and uneasy feelings. About 17% of the participants reported experiencing side effects after the second dose of the vaccine, including pain and edema (7.5%), body temperature (8.8%), and headache (7.3%). Most side effects were significantly associated with the Moderna vaccine (p < 0.001). Female students and those previously infected with COVID-19 were significantly associated with the side effects after taking the first dose of the vaccine.

Conclusion

We found that side effects are mild and did not pose a significant challenge to Bangladesh's effort in managing and reducing the risk associated with the COVID-19 pandemic.

Individual and social determinants of COVID-19 vaccine hesitancy and uptake in Northwest Syria

INTRODUCTION

The COVID-19 outbreak devastated the fragmented health system in Syria, a war-torn country, and exaggerated the demands for humanitarian assistance. COVID-19 vaccination was rolled out in Northwest Syria, an area out of government control, in May 2021. However, vaccine acceptance rates are still minimal, which is reflected in the meager percentage of vaccinated people. The study aims to investigate the effectiveness of the humanitarian actors' plans to address the COVID-19 vaccine hesitancy and conclude practical strategies for boosting vaccine uptake in Northwest Syria.

METHODS AND MATERIALS

Two questionnaires were developed to collect data from humanitarian organizations involved in the COVID-19 vaccination campaign and people from northwest Syria. Data analysis was performed using SPSS 22 data analysis program.

RESULTS

According to the findings, 55.5% of people refused the COVID-19 vaccine. The results showed a knowledge gap and lack of evidence regarding humanitarian actors' strategies to address the vaccine's low uptake. Besides, it was found that doctors and medical workers were reliable sources of information about the vaccine. However, they were not systematically engaged in community mobilization and risk communication to promote people's perspectives on the vaccine.

CONCLUSION

Risk communication and community engagement programs were not significantly associated with increasing the COVID-19 acceptance rate. Humanitarian actors must reconsider their strategies to address vaccine hesitancy in Northwest Syria. These strategies should engage medical professionals through dialogue sessions on the realities of the pandemic and vaccine development mechanism based on a compelling and evidence-based approach.

Outcomes following COVID-19 vaccination and associated factors among healthcare professionals in Oromia region, Ethiopia

Vaccines are not free from adverse outcomes. However, the evidence of adverse outcomes following COVID-19 vaccination among health-care professionals (HCPs) in the study setting was scanty. Aimed to assess outcomes following COVID-19 vaccination and associated factors among health-care professionals in Oromia region, Ethiopia. An online cross-sectional survey was conducted from 1 October to 30 October 2021. Data were collected using questionnaire created on Google forms. A snowball sampling technique through the authors' network on the popular social media was used. Data analysis was performed using SPSS version 25. The Adjusted Odd Ratio (AOR) along with the 95% confidence level and variables with a p value <.05 were considered to declare the statistical significance. About 93.9% of the participants had experienced mild-to-moderate adverse outcomes following COVID-19 vaccination. Being married [AOR = 4.19, 95% CI:2.07,8.45] ,family size >5 [AOR = 5.17, 95% CI: 1.74, 15.34], family not tested for COVID-19 [AOR = 0.39, 95% CI: 0.15,0.97], lack of family support to take the vaccine [AOR = 3.58, 95% CI: 1.75, 7.33], heard anything bad about the vaccine [AOR = 4.17, 95% CI: 1.90,9.13] and very concerned as the vaccine could cause Adverse Events Following Immunization (AEFI) [AOR = 6.24, 95% CI: 1.96,19.86] were statistically associated with the outcome. The study showed that over nine out-of-often participants had experienced mild-to-moderate adverse outcomes following COVID-19 vaccination. However, severe adverse outcome experienced was very low, which could not hinder to take the vaccine due to fear of its side effects. Marital status, family size, family tested for COVID-19, lack of family support to take the vaccine, hearing anything bad about the vaccine, and being concerned about as the vaccine could cause adverse events were factors associated with the outcome.

Adverse reactions following COVID-19 vaccine among healthcare professionals working in Ethiopia: a facility-based cross-sectional study

Background of the study

One of the best medical approaches for halting the spread of infectious diseases is vaccination. During the COVID-19 pandemic, healthcare workers (HCWs) were a high-risk population. Due to their susceptibility in terms of their working environment, front-line healthcare personnel should receive vaccinations before others.

Objective

The purpose of this study was to assess the adverse reactions to COVID-19 vaccines among Ethiopian healthcare professionals in 2022.

Methods

A facility-based cross-sectional study design was conducted in Addis Ababa Health Facilities, Ethiopia. A total of 290 health professionals who were vaccinated during the study period were involved. Data entry was done by Epidata (version 3.1) and analyzed using SPSS software version 26. Bivariable analysis was conducted and a p value of less than 0.25 was selected for further multivariable analysis. A p value of 0.05 was considered statistically significant at a 95% confidence level.

Results

A total of 277 study participants were successfully involved in the study, yielding a response rate of 95.5%. The study participants comprised 123 (44.4%) women and 154 (55.6%) men. The majority of them (202, 72.9%) had received the Oxford AstraZeneca vaccine. Among the 277 study participants, 142 (51.3%) had developed adverse reactions associated with vaccination. Of these, 81 (29.2%) had moderate adverse reactions. Only 2 (0.7%) had developed adverse reactions that led to hospitalization. The most reported short-term adverse reactions were injection site pain (151, 54.5%), headache (114, 41.2%), fever (104, 37.5%), fatigability and tiredness (94, 33.9%), chills (92, 33.2%), muscle pain (79, 28.5%), and decreased sleep quality (34, 12.3%). The multivariable logistic regression showed that the odds of having an adverse reaction were 1.501 times higher among women than men (AOR = 1.501, 95% CI [1.08, 2.754]).

Conclusion and recommendations

This study revealed that adverse effects following the COVID-19 vaccine were moderate in magnitude and minimal in severity. This study showed that adverse reactions that led to hospitalization were rare. Based on the findings of this study, it is recommended that national, multicenter, prospective, and randomized studies be conducted to assess the independent association of each vaccine.

Predictors of willingness to accept COVID-19 vaccine among adults

Background

Vaccines are an effective and ultimate solution that can decrease the burden of coronavirus disease 2019 worldwide. However, poor knowledge and unwillingness to accept this vaccine are key barriers to manage the COVID-19 pandemic in different countries including Ethiopia. Control of the pandemic will depend on the acceptance of coronavirus disease vaccine. However, there is a paucity of evidence on coronavirus disease vaccine acceptance in the study area. The current study was aimed to assess willingness to accept the COVID-19 vaccine and associated factors among adult clients attending Bule Hora University Teaching Hospital, West Guji Zone, southern Ethiopia.

Methods

An institution-based cross-sectional study was conducted among 385 study participants selected by a systematic random sampling technique. Data was collected through observation and structured questionnaires from April 10 to May 30, 2022. The collected data was cleaned and entered into EpiData 3.1 software before being exported to SPSS 25 statistical software for analysis. Bi-variable and multi-variable binary logistic regression model was used to identify the predictors of COVID-19 vaccine acceptance. The strength of association was measured using AOR with 95% confidence interval and significance was declared at p- value < 0.05.

Result

Magnitude of willingness to accept coronavirus disease-19 vaccine was 67.5% (95%Cl: 63-72). Good knowledge [AOR = 2.07, (1.17-3.64)], history of chronic disease [AOR = 2.59, (1.4-4.78)], being a government employee [AOR = 2.35 (1.1-5)], having a favorable attitude [AOR = 14.15 (5.25-37.46)], and good adherence [AOR = 1.74 (1.02-2.97)] were factors that significantly associated with willingness to accept the coronavirus disease 2019 vaccine.

Conclusion

Magnitude of willingness to accept the COVID-19 vaccine was considerable and needs to be improved. Knowledge, attitude, chronic illness, adherence, and being a government employee were factors that associated with willingness to accept the vaccine. Community awareness, advocacy, social mobilization and health education should be given at different levels.

COVID-19 Vaccine Safety Monitoring Studies in Low- and Middle-Income Countries (LMICs)-A Systematic Review of Study Designs and Methods

BACKGROUND

Post-marketing vaccine safety surveillance aims to monitor and quantify adverse events following immunization in a population, but little is known about their implementation in low- and middle-income countries (LMICs). We aimed to synthesize methodological approaches used to assess adverse events following COVID-19 vaccination in LMICs.

METHODS

For this systematic review, we searched articles published from 1 December 2019 to 18 February 2022 in main databases, including MEDLINE and Embase. We included all peer-reviewed observational COVID-19 vaccine safety monitoring studies. We excluded randomized controlled trials and case reports. We extracted data using a standardized extraction form. Two authors assessed study quality using the modified Newcastle-Ottawa Quality Assessment Scale. All findings were summarized narratively using frequency tables and figures.

RESULTS

Our search found 4254 studies, of which 58 were eligible for analysis. Many of the studies included in this review were conducted in middle-income countries, with 26 studies (45%) in lower-middle-income and 28 (48%) in upper-middle-income countries. More specifically, 14 studies were conducted in the Middle East region, 16 in South Asia, 8 in Latin America, 8 in Europe and Central Asia, and 4 in Africa. Only 3% scored 7-8 points (good quality) on the Newcastle-Ottawa Scale methodological quality assessment, while 10% got 5-6 points (medium). About 15 studies (25.9%) used a cohort study design and the rest were cross-sectional. In half of them (50%), vaccination data were gathered from the participants' self-reporting methods. Seventeen studies (29.3%) used multivariable binary logistic regression and three (5.2%) used survival analyses. Only 12 studies (20.7%) performed model diagnostics and validity checks (e.g., the goodness of fit, identification of outliers, and co-linearity).

CONCLUSIONS

Published studies on COVID-19 vaccine safety surveillance in LMICs are limited in number and the methods used do not often address potential confounders. Active surveillance of vaccines in LMICs are needed to advocate vaccination programs. Implementing training programs in pharmacoepidemiology in LMICs is essential.

Acute pancreatitis following COVID-19 vaccine: A case report and brief literature review

Vaccination is the most effective way to overcome COVID-19 morbidity and mortality. However, Covid-19 vaccines may cause potential adverse effects. We reported a 28-year-old healthy woman who was referred to the emergency department with a chief complaint of severe abdominal pain, nausea and hemoptysis. She has received two doses of COVID-19 vaccine (Sinopharm BIBP). Similar this time, three days after the injection of the second dose of the Sinopharm BIBP COVID-19 vaccine, abdominal and flank pain appeared, for which she has referred to the emergency department. After necessary tests and pancreatitis was confirmed, we started fluid therapy, plasmapheresis, gemfibrozil and insulin for patient management. The COVID-19 vaccines may lead to acute pancreatitis. The mechanism of pancreatitis caused by COVID-19 vaccines is unclear. Acute pancreatitis can develop after COVID-19 vaccination. This process can even happen a few months later. Therefore, to better diagnosis and prevention of long-term complications, it is necessary to measuring the lipase or amylase in patients that received COVID-19 vaccine if abdominal pain was occurred.

Possible oral manifestation after vaccination against COVID-19: a case report

The coronavirus disease 2019 (COVID-19) vaccines are not absolutely safe, and side effects might include oral manifestations, such as rash on the mucous membrane of the mouth and gingival hypertrophy. A 34-year-old male presented to the university dental clinic with malaise, high fever, weakness, tender gums, gingival hypertrophy, rashes on the mucous membrane of the oral cavity and halitosis. Dental professionals must be able to identify and differentiate between lesions of different varieties. This manifestation may be a new feature that can be checked during the history recording and examination part of treatment for patients vaccinated against the severe acute respiratory syndrome coronavirus 2 virus.

A retrospective evaluation of side-effects associated with the booster dose of Pfizer-BioNTech/BNT162b2 COVID-19 vaccine among females in Eastern Province, Saudi Arabia

BACKGROUNDS

The development of several types of vaccines to avert COVID-19 has taken place. Despite several reports of undesirable reactions noted post-COVID-19 vaccine administration, later remains one of the best prevention and management tools in fighting the spread of the virus and its variants and reducing the harshness of this viral attack. The purpose of the current paper was to explore the side-effects experienced by the females in the Eastern Province of Saudi Arabia directly after receiving the booster dose of the Pfizer-BioNTech/BNT162b2 COVID-19 vaccine.

METHODS

A descriptive cross-sectional study among adults living in the East-ern Province, Saudi Arabia was applied. A survey link was, distributed through WhatsApp, SMS, or e-mail to community members. Respondent's demographic information was acquired, as well as information about any local and systemic side-effects reported following booster dose of BioNTech/BNT162b2 COVID-19 vaccine.

RESULTS

A total of 72.36% (432/597) of the respondents who participated in this study reported at least one side-effect. Pain and redness at the injection site (75.93%), myalgia (71.99%), headache (53.24%), fever (33.56%), and fatigue (43.78%) were the highest frequently stated side-effects. Furthermore, 9.25% of the respondents had to see a physician due to side effects, plus merely four participants were admitted to the hospital. The respondents working in the non-healthcare-related sector had a 1.677-fold more possibility of side effects in comparison with the other respondents (adjusted odds ratio = 1.677; 95% CI = 1.363, 2.064).

CONCLUSIONS

All reported side-effects were mild to moderate. These findings might persuade pessimists and refusers to get the COVID-19 vaccine. Myalgia and pain or redness at the site of injection were the most common reported side-effects in our study.

COVID-19 and Bangladeshi health professionals: Infection status, vaccination and its immediate health consequences

Healthcare professionals play a pivotal role in protecting and saving the lives of general people. As health workers are more likely to be infected with COVID-19, it is inevitable to safeguard them through vaccination in advance to continue healthcare services. Hence the study aimed to explore the infection and vaccination status along with immediate health consequences among these frontiers. This was a cross-sectional, web-delivered study conducted among the 300 healthcare frontiers working at COVID-19 dedicated hospitals in eight divisions of Bangladesh. The study questionnaire encompasses infection, vaccination status with dose information, and demographical and organizational information among the respondents. A multivariate logistic regression model and Chi-square test was used for the analytical exploration. Adjusted and Unadjusted Odds Ratio with a 95% confidence interval was calculated for the specified setting indicators. The study revealed that 49% of all respondents tested positive whereas 98% of them were found vaccinated of which mostly (52.3%) had their 2nddoses and 68.7% faced immediate health consequences for having the vaccination. As predictor for COVID-19 infection status, young and senior adult group (30–39 years: AOR = 2.01/0.03; 95% CI: 1.08–3.76; >50 years: AOR = 4.36/0.01; 95% CI: 1.65–11.55) and respondents who received Sinopharm as their vaccine found to have more significant positive infection history. The predictors regarding experiencing immediate health effects after vaccination, surprisingly female (AOR = 3.31/0.01; 95% CI: 1.82–6.04) health professionals of the capital city (AOR = 1.91/0.03; 95% CI: 1.06–3.46) were observed to have health consequences on vaccination. As the older female group (>50 years) in the nursing profession was found more infected with COVID-19 and a significant number of health professionals especially the age group (30–39 years) in the nursing profession experienced immediate health effects of COVID-19 vaccination, implementation of specific strategies and policies are needed to ensure the safety precaution and effective vaccination among the health professionals of Bangladesh.

Self-reported side effects of the Oxford AstraZeneca COVID-19 vaccine among healthcare workers in Ethiopia, Africa: A cross-sectional study

Introduction

Ethiopia is the second most populous country in Africa. Ethiopia received most of its COVID-19 vaccines through donations. The Oxford AstraZeneca vaccine is the first to be donated to Ethiopia by the COVAX facility. Healthcare workers were the priority population that received the Oxford AstraZeneca COVID-19 vaccine. However, there was no nationwide study on the safety of the vaccine in Ethiopia. This study aimed to measure the prevalence and predictors of self-reported side effects of the Oxford AstraZeneca vaccine.

Materials and methods

The study employed a cross-sectional design. A sample of healthcare workers who took Oxford AstraZeneca COVID-19 vaccine was drawn from four regions of Ethiopia; namely, Amhara, Oromia, Somali, and Southwest. Data were collected on sociodemographic characteristics, medical anamnesis, COVID-19 related anamnesis, and COVID-19 vaccine anamnesis via telephone interview. Descriptive and inferential analyses were done. The software, IBM SPSS Statistics v21.0, was used for analyses of data.

Results

Out of 384 people, 346 responded (response rate: 90.1%). Female accounted for 34.1% of the respondents. The mean age of the respondents was 31.0 years (Standard Deviation (SD) = 7.4). Nurses accounted for 43.7% of the respondents. The prevalence of at least one local- and systemic-side effect was 50.6 and 44.5%, respectively. The most frequent local- and systemic- side effect were injection site pain and headache, respectively. Both types of side effects mostly subsided in the first 3 days. A third of healthcare workers with side effects took at least one medication. Paracetamol followed by diclofenac sodium were taken by healthcare workers to overcome side effects. There was no independent predictor of local side effect. After controlling for age and chronic diseases, the odds of healthcare workers with COVID-19 like symptoms to experience systemic side effects was 1.38 (Confidence Interval (CI): 1.04–1.82) times more than that of healthcare workers without COVID-19 like symptoms.

Conclusions

The prevalence of local- and systemic-side effects of the Oxford AstraZeneca COVID-19 vaccine was modest. As the symptoms were mostly common in the first 3 days, it is preferable to monitor healthcare workers at least in the first 3 days following the administration of the vaccine.

Willingness of the Jordanian Population to Receive a COVID-19 Booster Dose: A Cross-Sectional Study

SARS-CoV-2 (COVID-19) vaccines are critical for containing serious infections. However, as COVID-19 evolves toward more transmissible varieties and serum antibody levels in vaccinated persons steadily decline over time, the likelihood of breakthrough infections increases. This is a cross-sectional study based on an online questionnaire for Jordanian adults (n = 915) to determine how individuals who have finished the current vaccination regimen feel about a prospective COVID-19 booster shot and what factors might influence their decision. Almost half of the participants (44.6%) intended to get the booster dose of the COVID-19 vaccine. The most frequently mentioned reasons for participants’ reluctance to get the COVID-19 vaccine booster dose were “The benefits of booster dose have not been scientifically proven” (39.8%), followed by “I took the last dose a short time ago, and there will be no need to take the booster dose for at least a year” (24.6%). In turn, “I was infected with COVID-19; thus, I do not require the booster dose” was the least reported reason (13.1%). These findings highlight the considerable hesitancy toward COVID-19 booster immunization among Jordanians, as well as the variables associated with vaccine hesitancy and the most frequently mentioned reasons for hesitancy, which will aid in creating excellent campaigns regarding booster doses.

Acceptance of COVID-19 Vaccine and Its Associated Factors Among Ethiopian Population: A Systematic Review

INTRODUCTION

Coronavirus disease 2019 (COVID-19) is a global health threat. Millions of lives were lost to COVID-19 and it has caused a substantial economic crisis throughout the world. The development of coronavirus vaccines has pinned a new hope in combating the pandemic. The success of vaccination and development of herd immunity highly depend on the willingness to be vaccinated, not merely on the availability of a vaccine. This review aims to provide comprehensive evidence on acceptance of COVID-19 vaccine and its associated factors in Ethiopia.

METHODS

Literature searching was done using PubMed, Google scholar and Science direct databases. Studies conducted in Ethiopia, published in English language from inception until January 9, 2022 were included. Retrieved articles were screened based on titles, abstracts and full text reading to identify studies that met the inclusion criteria. About 21 eligible studies were included in this systematic review. The data were extracted using a data extraction checklist.

RESULTS

A total of 2058 records were retrieved, of which 21 were eligible for this systematic review. All of the articles were cross-sectional studies published in 2021. In Ethiopia, the level of COVID-19 vaccine acceptance ranged from 31.4% to 92.33%. The vaccine acceptance level was significantly associated with age groups, sex, educational status, perceived susceptibility, perceived benefit, knowledge about COVID-19 vaccine, and other socio-demographic factors.

CONCLUSION

A significant portion of the studies revealed vaccine acceptance level was low. Variation of vaccine acceptance was associated with socio-demographic factors (age, sex, educational status, etc.), information-related factors, and other health-related behaviors. Dissemination of clear and adequate information concerning the vaccine might be the required prior activity to increase acceptance of the vaccine. Hence, there should be a coordinated effort to halt the pandemic through increasing the acceptance of COVID-19 vaccine.
