Interest in COVID-19 vaccine trials participation among young adults in China: Willingness, reasons for hesitancy, and demographic and psychosocial determinants

College students' knowledge and attitudes toward clinical trials and their relationship with willingness to participate in COVID-19 trials or vaccines

OBJECTIVE

We examined clinical trial knowledge and attitudes, and their relationship with willingness to participate in COVID-19 vaccine trials, and willingness to accept a COVID-19 vaccine among college students.

PARTICIPANTS

331 undergraduates: mean age 25; 72% women; and 78% white.

METHODS

We administered an online, anonymous survey to undergraduate students in July, 2020, during the COVID-19 pandemic.

RESULTS

The mean clinical trial knowledge score was 65% (SD = 16) correct. The mean attitudes toward clinical trials score (1 most negative: 5 most positive) was 3.3 (SD = 0.5). Attitudes toward clinical trials were associated with likelihood of COVID-19 trial participation (positive 76% vs. negative 35%, p = 0.001) and a trend toward likelihood of accepting a COVID-19 vaccine if available (positive 89% vs. negative 67%, p = 0.066).

CONCLUSIONS

General clinical trial knowledge and attitudes appear to be important targets for educational interventions. Furthermore, fostering positive attitudes may lead to improved COVID-19 trial participation and vaccine uptake.

COVID-19 Vaccine Knowledge and Attitude Among Healthcare Workers in Jeddah, Saudi Arabia

Background On March 11, 2020, the World Health Organization (WHO) proclaimed coronavirus disease 2019 (COVID-19) a pandemic. COVID-19 can result in asymptomatic infection, severe pneumonia, and death. In this study, healthcare workers in Jeddah, Saudi Arabia, were asked to reflect on their knowledge of and attitudes toward the COVID-19 vaccine. Methods Online anonymous polling of healthcare professionals in Jeddah, Saudi Arabia, was done. During the COVID-19 pandemic, the respondents' demographic information and knowledge of and attitudes toward the COVID-19 vaccine were gathered through a questionnaire. Both descriptive and inferential statistics were used to analyze the data. Results The knowledge of the responders for each vaccine is as follows: Pfizer-BioNTech, 96.1%; AstraZeneca-Oxford, 66.1%; Moderna, 56.9%; and Johnson & Johnson's Janssen, 18.2%. A small percentage of responders (5.7%) believe that COVID-19 vaccination may alter their DNA, while 70% believe it can prevent them from getting sick with COVID-19 infection. Half of the responders had a wrong opinion of COVID-19 vaccinations. Conclusion The findings imply that improving healthcare workers' knowledge of vaccines and changing attitudes toward vaccination may increase vaccine acceptability. This would involve addressing the respondents' concerns about vaccine side effects and their general mistrust of vaccine benefits.

In or Out? Identifying the Factors Playing a Role in Covid-19 Decision Making in Turkiye

OBJECTIVE

The study aimed at investigating the social, demographic, and economic factors affecting Covid-19 vaccine decisions before the vaccination started in Turkey. The study also aimed to understand the attitudes towards Covid-19 vaccines.

METHODS

The study was conducted by exploiting the data of 693 individuals living in Turkey. The data was collected via a virtually applied questionnaire according to snowball sampling in late 2020 when the vaccination program had not started in Turkey yet. Multinomial logistic regression design was used to identify the factors affecting Covid-19 vaccine decisions.

RESULTS

It was observed that Covid-19 vaccine acceptance was notably low before the vaccination started in Turkey. Further, almost 50% of the participants were indecisive about getting vaccinated. It was identified that age, gender, educational status, and residential status, as well as occupational status, the number of dependents, smoking, and the vaccination of governmental authorities, have associations with Covid-19 vaccination decisions.

CONCLUSIONS

Covid-19 vaccine acceptance is generally low, although it is relatively high among vulnerable groups (i.e., the elderly and smokers), and among those who are unable to isolate themselves. In addition, the vaccination of governmental authorities is remarkably effective on Covid-19 vaccine acceptance in Turkey.

Inactivated COVID-19 vaccine hesitancy among midwifery students: a prospective online survey

Limited information on vaccines' reliability and lack of sufficient scientific data may cause suspicion among individuals concerning the Coronavirus Disease-2019 (COVID-19) vaccines. This study aimed to investigate the attitudes of midwifery students to an inactivated COVID-19 vaccine. This prospective online survey was conducted between 01 March and 01 May 2021 with 172 midwifery students. An anonymous online survey was developed by the researchers, taking into account the studies in the literature examining the attitudes of individuals towards the vaccine. The online survey included a total of 19 questions, covering five main topics. The study revealed that 118 (68%) of 172 midwifery students were hesitant to get vaccinated. There was a significant difference between the vaccine-hesitant and -accepting groups regarding the general attitude towards the vaccine (respectively; <0.001, 0.001). It was determined that 48.1% of the vaccine-accepting participants strongly agreed that this vaccination should be mandatory for all midwifery students working in a clinical practice internship. Higher vaccination willingness levels are expected in students who attend health curricula due to the high literacy level in health-related issues. In conclusion, healthcare professionals who are in contact with patients should be informed more accurately about newly developed vaccines.IMPACT STATEMENTWhat is already known on this subject? Limited information on vaccines' reliability and lack of sufficient scientific data caused suspicion about the COVID-19 vaccines among many people .What do the results of this study add? Almost half of the participants in both groups agreed that the vaccine could be ineffective if the virus is mutated. Nearly half of the hesitant group thought that the COVID-19 vaccine might not be effective and were concerned about serious side effects.What are the implications of these findings for clinical practice and/or further research? This study reveals that healthcare professionals who are in contact with patients should be informed more accurately about newly developed vaccines.

To Vaccinate or Not to Vaccinate-Reasons of Willingness and Reluctance of Students against SARS-CoV-2 Vaccination-An International Experience

Despite the vaccine against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) being reported to be safe and effective, the unwillingness to vaccinate and doubts are still common. The aim of this international study was to assess the major reasons for the unwillingness to vaccinate in a group of students from Poland (n = 1202), Bangladesh (n = 1586), India (n = 484), Mexico (n = 234), Egypt (n = 566), Philippines (n = 2076), Pakistan (n = 506), Vietnam (n = 98) and China (n = 503). We conducted an online cross-sectional study that aimed to assess (1) the percentage of vaccinated and unvaccinated students and (2) the reasons associated with willingness/unwillingness to the vaccine. The study included 7255 respondents from 9 countries with a mean age of 21.85 ± 3.66 years. Only 22.11% (n = 1604) of students were vaccinated. However, the majority (69.25%, n = 5025) expressed a willingness to be vaccinated. More willing to vaccinate were students in informal relationships who worked mentally, used psychological/psychiatric services before the pandemic, and studied medicine. There are cultural differences regarding the reasons associated with the unwillingness to vaccinate, but some 'universal' might be distinguished that apply to the whole group.

Predictors of COVID-19 vaccine acceptability among health professions students in Vietnam

Background

The COVID-19 vaccine hesitancy or refusal has actually been a threat to global health. In the current situation, health professions students are at risk for SARS-CoV-2 infection during their internship at healthcare facilities. Furthermore, those future healthcare workers will advise people to accept the COVID-19 vaccination. Therefore, the attitude of students towards vaccine acceptance and the predicting factors needs to be elucidated. This study applied the Health Belief Model to determine predictors of COVID-19 vaccine acceptability among health professions students.

Methods

Nine hundred eleven students participated in a cross-sectional online survey in Vietnam. Data were collected from 1st April to 30th June 2021. Data analysis was performed using SPSS software version 20.0 with Chi-square and Kruskal-Wallis tests before executing multinomial logistic regression to identify predictors of the COVID-19 vaccine acceptability

Results

The overall vaccine acceptance, hesitancy, and refusal rates were 58% (95% CI: 54.7% - 61.3%), 40.4% (95% CI: 37.2% - 43.7%) and 1.5% (95% CI: 0.8% - 2.6%), respectively. Regarding vaccination hesitancy, a predictor such as "Receiving recent flu shots” had a negative correlation, whereas "Vaccines have little efficacy & serious adverse effects” (Perceived barriers), nationality, and majors were positive correlates. For refusal, "Unvaccinated students feasibly infected COVID-19 during hospital internship” (Perceived susceptibility) was a negative correlate. For predicting both hesitancy and refusal, "Mass media appreciating effectiveness and safety of vaccines" (Cues to action), and " Health professions students get serious complications of COVID-19 if not vaccinated" (Perceived severity) were negative predictors. In contrast, "Manufacturers do not disclose adverse effects of vaccines" (Cues to action), and "Adverse effect causes death" (Perceived barrier) were recognized as positive predictors. Strong Health Belief Model predictors of vaccine refusal were "Manufacturers do not disclose adverse effects of vaccines" (Cues to action) with OR= 5.299(95% CI: 1.687-16.641, p= 0.004), and "Adverse effect causes death" (Perceived barrier) with OR= 10.255 (95% CI = 3.528-29.814, p= 0.0005).

Conclusion

Health professions students' acceptability of COVID-19 vaccination might be based on the perceived susceptibility to and severity of COVID-19, concerns about vaccine efficacy and safety, and the influence levels of information from various sources. Health education and measures to prevent the harmful effects of COVID-19 vaccine misinformation could potentially improve the acceptance rate of the COVID-19 vaccine

Uptake and adverse reactions of COVID-19 vaccination among people living with HIV in China: a case-control study

OBJECTIVES

The coronavirus disease-2019 (COVID-19) pandemic continues to ravage the world. People living with HIV (PLHIV) are one of the most vulnerable groups. This study aims to identify the factors associated with the uptake and adverse reactions of COVID-19 vaccination.

METHODS

We recruited PLHIV in China by convenience sampling between 7 and 23 February 2021. Participants were asked to complete an online questionnaire. Chi-squared test and multivariable logistic regression were used to assess factors associated with vaccine uptake.

RESULTS

A total of 527 vaccinated and 1091 unvaccinated PLHIV were recruited. Individuals who had a higher education, engaged in occupations with a higher risk of COVID-19 infection, received influenza or pneumonia vaccine in the past 3 years (5.40, 3.36-8.77), believed in the effectiveness of vaccines (3.01, 2.20-4.12), and received media information regarding COVID-19 vaccine (2.23, 1.61-3.11), were more likely to be vaccinated. Concerning about adverse reactions (0.31, 0.22-0.44), negative impact on the progression of HIV/AIDS (0.36, 0.26-0.50) or antiretroviral therapy (ART) (0.61, 0.44-0.85), disclosure of HIV infection status (0.69, 0.49-0.96), comorbidities (0.33, 0.22-0.47), being unmarried (0.43, 0.28-0.66) and older age were negatively associated with vaccination. Of the 527 vaccinated PLHIV, 155 (29.4%) PLHIV reported adverse reactions, with pain at the injection site being the most common (18.2%).

CONCLUSIONS

PLHIV, who are concerned about adverse reactions, negative impact on ART outcome and disclosure of HIV infection status, were less likely to adopt COVID-19 vaccination. To increase vaccination coverage among PLHIV, health-care professionals should emphasize the benefits and necessity of vaccination and provide consultancy regarding adverse reactions.

The mediating role of health literacy on the relationship between health care system distrust and vaccine hesitancy during COVID-19 pandemic

This study explores the mediating role of health literacy on the association between health care system distrust and vaccine hesitancy. An online survey including Personal Information Form, Health Care System Distrust Scale, Vaccine Hesitancy Scale, and Health Literacy Scale were applied to 620 participants. The degree of applying mask-wearing, hygiene rule and physical distance, and the level of COVID-19 vaccine literacy were modeled with hierarchical multiple regression analysis to have a deeper analysis of participants’ actions towards COVID-19 vaccine hesitancy. It was found that health care system distrust and health literacy were the most important variables that had an impact on vaccine hesitancy. Based on the mediation analysis, the total effect of health care system distrust on vaccine hesitancy was statistically significant. Participants who held a low level of health literacy and a high perception of the health care system distrust experienced more vaccine hesitancy. The findings suggested the health literacy mediated the relationship between health care system distrust and vaccine hesitancy. Health authorities need to consider the dynamic and complex factors around the health care system distrust and health literacy to reduce vaccine hesitancy during COVID-19.

Willingness to Receive SARS-CoV-2 Vaccination and Associated Factors among Chinese Adults: A Cross Sectional Survey

Vaccination is a key strategy to prevent the pandemic caused by the coronavirus disease 2019 (COVID-19). This study aims to investigate the willingness of Chinese adults to be vaccinated against COVID-19 and further explore the factors that may affect their willingness. We used a self-design anonymous questionnaire to conduct an online survey via the Sojump. A total of 1009 valid questionnaires were analyzed. The age of the participants ranged from 18 to 74. Among them, 609 (60.4%, 95%CI: 57.4-63.4%) were willing to receive the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine. Logistic regression analysis results showed that the age of 30-49 (OR = 2.042, 95%CI: 1.098-3.799), universities and colleges education (OR = 1.873, 95% CI = 1.016-3.451), master degree or above education (OR = 1.885, 95%CI = 1.367-2.599), previous influenza vaccination history (OR = 2.176, 95%CI: 1.474-3.211), trust in the effectiveness of the vaccine (OR = 6.419, 95%CI: 3.717-11.086), and close attention to the latest news of the vaccine (OR = 1.601, 95%CI: 1.046-2.449) were facilitative factors that affected their willingness to be vaccinated. More than half of the adults in China would be willing to receive a SARS-CoV-2 vaccine. Middle-aged people with higher education, those who had been vaccinated against influenza, and those who believed that COVID-19 vaccine was effective and paid close attention to it were more willing to be vaccinated. Our findings can provide reference for the implementation of vaccination and the prevention of COVID-19 in China. More studies are needed after the vaccine is launched.

The Psychological Impact of COVID-19 Pandemic on Graduating Class Students at the University of Gondar, Northwest Ethiopia

INTRODUCTION

A poorly known contagious disease outbreak, like COVID-19, leads to unavoidable stress, fear, and anxiety. During the pandemic, University students suffer from adverse mental health outcomes resulted from the continuous spread of the disease, sensational media reporting, and implementation of social lockdown. Graduating class students are more affected due to cancellation and postponing of anticipated events such as exchange studies and graduation ceremonies. This study aimed to assess the prevalence and associated factors of anxiety, depression, and stress among graduating class students.

METHODS

Institution-based cross-sectional study was conducted from November 10 to 30, 2020 at the University of Gondar. A simple random sampling technique was employed to select 350 students. Data were collected using a structured self-administered questionnaire, entered in EPI DATA version 3, analyzed using SPSS version 21, and presented in frequencies, percentages, tables, and graphs. Bivariable and multivariable analysis was investigated using a binary logistic regression model.

RESULTS

The prevalence of stress, anxiety, and depression among graduating class students was 22.2%, 39.6%, and 40.2% respectively. Living in an urban area, living with a family, sedentary lifestyle, unable to practice COVID-19 preventive measures, and having a contact history increases the risk of developing stress. Living in an urban area, substance use, sedentary lifestyle, and fear of infecting family increase the risk of developing anxiety. Students who came from an urban area, live with a family, study non-health departments, had confirmed cases in the family and did not perform physical exercise had higher odds of developing depression.

CONCLUSION

More than one-fifth, more than one-third, and nearly two-fifths of graduating students had stress, anxiety, and depression respectively. It is better to develop effective strategies and interventions, train students about self-protection, and establish a psychological crisis intervention team to minimize the psychological impact of the COVID-19 pandemic.

Influences on Attitudes Regarding Potential COVID-19 Vaccination in the United States

The COVID-19 pandemic continues to ravage the world, with the United States being highly affected. A vaccine provides the best hope for a permanent solution to controlling the pandemic. However, to be effective, a vaccine must be accepted and used by a large majority of the population. The aim of this study was to understand the attitudes towards and obstacles facing vaccination with a potential COVID-19 vaccine. To measure these attitudes a survey was administered to 316 respondents across the United States by a survey corporation. Structural equation modeling was used to analyze the relationships of several factors with attitudes toward potential COVID-19 vaccination. Prior vaccine usage and attitudes predicted attitudes towards COVID-19 vaccination. Assessment of the severity of COVID-19 for the United States was also predictive. Approximately 68% of all respondents were supportive of being vaccinated for COVID-19, but side effects, efficacy and length of testing remained concerns. Longer testing, increased efficacy and development in the United States were significantly associated with increased vaccine acceptance. Messages promoting COVID-19 vaccination should seek to alleviate the concerns of those who are already vaccine-hesitant. Messaging directed at the benefits of vaccination for the United States as a country would address the second predictive factor. Enough time should be taken to allay concerns about both short- and long-term side effects before a vaccine is released.
