COVID-19 Vaccine Willingness and Related Factors Among Health Care Workers in 3 Southeast Asian Jurisdictions.

Importance: COVID-19 vaccine hesitancy is widespread and may lead to refusal or delay of vaccination, eventually reducing the overall vaccination coverage rate and vaccine effectiveness. Willingness to receive COVID-19 vaccination among health care workers (HCWs) is diverse across different jurisdictions. Objective: To assess the COVID-19 vaccine willingness among HCWs in 3 Southeast Asian jurisdictions in the context of pandemic severity and vaccination policy. Design, Setting, and Participants: A cross-sectional online survey was conducted among frontline HCWs in Hong Kong, Nepal, and Vietnam from May to November 2021. Eligible participants were nurses and doctors aged 18 and older, working in public or private health care settings on a full-time or part-time basis. Exposures: The COVID-19 pandemic and vaccination policy. Main Outcomes and Measures: COVID-19 vaccination willingness was defined as HCW willingness toward receiving the COVID-19 vaccine in full course or the first dose of the vaccine, and willingness to take the second dose. Information on sociodemographic characteristics, the history of seasonal influenza vaccination, attitudes toward vaccination, and opinions on strategies associated with vaccination uptake from the study participants. Results: Among the 3396 eligible doctors and nurses who participated in the survey, 2834 (83.4%) were from Hong Kong, 328 (9.7%) were from Nepal, and 234 (6.9%) were from Vietnam. Most respondents were female (76.2% [2589 ]), aged 30 to 39 years (31.2% [1058]), and nurse HCWs (77.6% [2636]); the response rates were 11% (2834 of 25 000) in Hong Kong, 36% (328 of 900) in Nepal, and 13% (234 of 1800) in Vietnam. Overall, the prevalence rate of willingness to take the COVID-19 vaccine was highest in Nepal (95.4% [313 of 328]), followed by Vietnam (90.6% [212 of 234]), and lowest in Hong Kong (54.4% [1542 of 2834]), relating to their different attitudes and opinions toward the COVID-19 vaccination, and the pandemic severity and vaccination policy in the 3 jurisdictions. Doctors were more willing to take COVID-19 vaccination than nurses (odds ratio, 5.28; 95% CI, 3.96-7.04). Older age (odds ratios, 1.39-3.70), male gender (odds ratio, 1.41; 95% CI, 1.11-1.75), higher educational level (odds ratio, 1.48; 95% CI, 1.17-1.87), and having seasonal influenza vaccination uptake history (odds ratio, 2.15; 95% CI, 1.82-2.54) were found to be associated with increased willingness. Choice of vaccination brand with adequate information, immunity passport, time off from work for vaccination and subsidy for travel to inconvenient vaccination centers were considered as strategies to enhance vaccine willingness. Conclusions and Relevance: In this survey study, vaccination unwillingness existed among HCWs in Southeast Asian regions, especially in Hong Kong. The findings of this study may have utility in the formulation of vaccination promotion strategies such as vaccination incentives. Attitudes toward vaccination in HCWs might be examples for the general population; however, changes over time should be further investigated.

Knowledge about COVID-19 vaccine and vaccination in Vietnam: A population survey.

BACKGROUND: Coronavirus disease 2019 (COVID-19) vaccine acceptance is essential in controlling the virus. Vaccine knowledge influences vaccine acceptance and understanding this is vital in planning immunization strategies. OBJECTIVES: This study aimed to examine the public COVID-19 vaccine knowledge levels and predictors of low knowledge levels in Vietnam. METHODS: A cross-sectional, community-based survey was conducted between April 16 and July 16, 2021. To examine the community knowledge levels regarding the vaccine essentialness and efficacy, a self-administered questionnaire was developed and comprised 7 questions with 5 Likert scale responses corresponding to the levels of agreement or disagreement with the provided statements and scores ranging from 0 to 4. An individual's knowledge score above the mean score of all participants was defined as "acceptable" and that below was defined as "low." RESULTS: Among 1708 respondents, the mean age was 34.3 ± 13.4 years, 942 (55.2%) were females, and 797 (46.7%) had acceptable knowledge levels. Age (adjusted odds ratio [AOR] 0.984 [95% CI 0.972-0.995], P = 0.005) and being vaccinated against COVID-19 (0.653 [0.431-0.991], P = 0.045) were inversely associated with lower knowledge levels. Those with a Gapminder income of $8 to < $15 per day (1.613 [1.117-2.329], P = 0.001), $2 to < $8 (2.093 [1.313-3.335], P = 0.002), and < $2 (3.341 [1.951-5.722], P < 0.001), less than a high school education (4.214 [1.616-10.988], P = 0.003), and nonclinical professionals and nonhealth lecturers (1.83 [1.146-2.922], P = 0.01) were positively associated with lower knowledge levels. CONCLUSION: To ensure a successful vaccine rollout, it is crucial to improve community knowledge about vaccine essentialness and efficacy. Those who are at young age, who have low income or education levels, and working in nonclinical and nonhealth education fields should be the target of the intervention programs. Community education programs may benefit from using those who have been immunized as role models.

Assessment of Hand Hygiene Practices of University Students in Vietnam Amid the COVID-19 Pandemic: A Brief Report.

OBJECTIVE: Effective handwashing practices help prevent the spread of coronavirus disease 2019 (COVID-19). This study examined the knowledge, frequency, and characteristics of handwashing practices among Vietnamese university students. METHODS: An analytic cross-sectional study was conducted on all students enrolling at Phenikaa University in Vietnam. A self-developed questionnaire was used to collect information on the participants' knowledge regarding the effectiveness of handwashing as a COVID-19 preventive measure, the moments for hand hygiene, the most appropriate practices in different situations, and frequency. RESULTS: Among 728 study participants, 460 (63.2%) were from health-related faculties. Almost (97.9%; 713/728) all participants knew that handwashing could protect against the spread of infection, but less than half performed handwashing often in a normal day (47.4%; 345/728), after sneezing or coughing (48.9%; 356/728), and 7.4% (54/728) only washed hands when hands are visibly dirty. Health students used alcohol-based handrub in all situations, including those requiring handwashing with water and soap (P < 0.05). CONCLUSIONS: The levels of knowledge regarding the effectiveness of handwashing among study participants are high, but actual practices of handwashing are suboptimal. It is crucial to improve community education to help reinforce correct hand hygiene behaviors, including when to wash hands and which method should be used.

Evaluating COVID-19 vaccine hesitancy: A qualitative study from Vietnam.

BACKGROUND AND AIMS: Vaccine hesitancy is a major threat to COVID-19 vaccination programs. This study aimed to examine the public attitudes towards COVID-19 vaccines, the variance of these attitudes, and associated determinants within a large COVID-19 outbreak in Vietnam. METHODS: Two focus group discussions were conducted online with 20 people from different socio-economic and profession backgrounds. Purposive sampling was used to recruit participants. Discussions were recorded and transcribed verbatim. Key themes were extracted using reflexive thematic analysis method. RESULTS: Four distinct, non-static attitudes including acceptance, conditional acceptance, hesitancy, and anti-vaccination were found. Themes identified as determinants of these attitudes were external factors, internal factors, and risk-benefit self-assessment regarding COVID-19 vaccination. CONCLUSIONS: We found mixed, non-static COVID-19 vaccination attitudes. People's vaccination risk-benefit self-assessment greatly determines the variance of their attitudes over time. Given high public trust in the authorities, the government should take the lead to counter COVID-19 vaccine misinformation. To increase acceptance, vaccine advertising campaigns should focus on providing information about the dangers of COVID-19, the ability to manage side-effects at the vaccination centers, and updated, precise information on both the outbreak and vaccines. Future research is needed to identify the public most common COVID-19 information channels to enable effective community education.

Comparison of Resilience Among Healthcare Workers During the COVID-19 Pandemics: A Multinational Cross-Sectional Survey in Southeast Asian Jurisdictions.

Objectives: To examine the level of resilience among the frontline healthcare workers (HCWs) in four different Southeast Asian jurisdictions and identify the potential factors that may enhance healthcare workers resilience. Methods: An online cross-sectional survey was carried out among 3,048 eligible healthcare workers in Hong Kong, Nepal, Vietnam, and Taiwan from May 2021 to July 2022, and information on individual resilience, socio-demographic characteristics, organizational supports, and personal exposures were collected. A binary logistic regression model was used to identify the factors that were associated with a high resilience level. Results: The resilience score was the highest among healthcare workers of Vietnam, followed by Taiwan and Hong Kong, with Nepal scoring the lowest. Participants with old age, part-time work, higher education level, more satisfaction with workplace policy, better organizational supports, and fewer COVID-specific worries were associated with higher resilience. Healthcare workers who were satisfied with the overall organizational policy support had an OR of 1.48 (95% CI: 1.25-1.76) for a high resilience level. Conclusion: Implementing satisfying organizational policies and establishing supportive work environments for frontline healthcare workers can increase individual resilience and organizational stability.

The Levels of COVID-19 Related Health Literacy among University Students in Vietnam.

BACKGROUND: Vietnam is among the few countries that were successful in the fight against the first wave of coronavirus disease 2019 (COVID-19). However, subsequent domestic outbreaks of COVID-19 continue to occur. To sharp the community education program to guarantee the final success in the fight against COVID-19 in Vietnam and comparable countries, we examined the levels of COVID-19 knowledge and associated predictors among university students in Vietnam. MATERIALS AND METHODS: A cross-sectional study was conducted on all students enrolling at Phenikaa University using a self-developed questionnaire consisted of 20 questions regarding COVID-19's risk factors, transmission routes, symptoms, and prevention. RESULTS: Among 728 participants, 40.9% were male, 63.2% studied health-related majors, and 18.1% lived alone. Correct response rates ranged from 25.3% to 98.9% across 20 questions. Only 51.9% (378/728) of participants had good knowledge levels. Studying health majors (adjusted odds ratio [AOR] 0.547, 95% confidence interval [CI] 0.398 - 0.751, P <0.001), and living with the seniors (AOR 0.612, 95% CI 0.389 - 0.963, P = 0.034) or with friends (AOR 0.405, 95% CI 0.252 - 0.650, P <0.001) were negatively associated with a poor level of COVID-19 knowledge. CONCLUSION: The proportion of university students having good knowledge levels is suboptimal. It is essential to improve the quality of COVID-19 education with a more focus on not only the preventive measures, but also the disease itself. More studies are needed to improve the level of COVID-19 knowledge among those living alone or do not study health-related majors.

A Cross-Sectional Study of Knowledge, Attitude, and Practice Towards Face Mask Use Amid the COVID-19 Pandemic Amongst University Students in Vietnam.

Although Vietnam has been successful in the fight against the first wave of COVID-19, domestic outbreaks have continued to occur. Given university students constitute a significant proportion of the population in Vietnam, to improve the prevention and control of COVID-19 in Vietnam and comparable countries, we examined their knowledge, attitude, and practice (KAP) towards face mask use which is an important preventive measure and the association between the levels of COVID-19 knowledge and KAP towards face mask use. A cross-sectional survey was conducted on all students studying at Phenikaa University, Hanoi, using a self-developed questionnaire consisted of 42 questions regarding KAP towards face mask use as well as reuse of cloth mask, and COVID-19 knowledge. Among 728 participants, 40.9% (298/728) were male, 63.2% (460/728) were from health-related faculties, 46% (335/728) lived in urban areas, and 51.9% (378) had good levels of COVID-19 knowledge. Regarding face mask, most (89.7%, 653/728) participants had good knowledge scores, 72.8% (530/728) had positive attitudes, and 76.5% (557/728) had good practice scores. The most common types of masks used were surgical mask (57.6%, 419/728), followed by non-antibacterial cloth mask (23.1%, 168/728). Among 168 participants using non-antibacterial cloth mask, 43.5% reused masks (73/168), of whom 6.8% (5/73) did not wash their masks at least daily. Face mask use knowledge was statistically associated with COVID-19 knowledge (P < 0.001). Face mask use attitudes were statistically associated with education levels (P = 0.02), and COVID-19 knowledge (P < 0.001). Practice of face mask use was statistically associated with gender (P = 0.03), geographical distribution (P = 0.04), academic majors (P = 0.02), and COVID-19 knowledge (P = 0.01). The levels of KAP towards face mask use among Vietnamese university students are high. It is important to continue to enforce the mass masking policy, together with the ongoing community education with an emphasis on the route of COVID-19 transmission and how correct face mask use can stop the spread. To ensure the effectiveness of face masks, there is an urgent need to educate the community regarding the procedures for cloth masks re-use.

Who Influences the Public Intention to Get a COVID-19 Vaccine and What are the Public References and Concerns? A Population Survey in Vietnam.

BACKGROUND: Coronavirus disease 2019 (COVID-19) vaccine acceptance is influenced by the trusted recommenders. This survey examined the public references, concerns, and trust in seven groups of recommenders regarding COVID-19 vaccine in Vietnam. MATERIALS AND METHODS: A cross-sectional survey was conducted on 1,579 participants between April 16 and July 16, 2021. Participants' references, concerns, and responses to vaccination recommendations made by government officials, employers, physicians, nurses, pharmacists, senior family members, and religious leaders were captured using a self-administered questionnaire. RESULTS: Rates of trust ranged from 18.5% to 89.1%. The highest rates were attributable to government (89.1%) and physicians (85.9%). Less than half of participants would accept the vaccines if pharmacists (45.5%), nurses (44.7%), employers (42.4%), senior family members (28.1%), and religious leaders (18.4%) recommended it. Only 37.6% of participants thought that vaccines were safe for them, while 57% were unsure. Most participants would wait and see how people respond to the vaccines before getting vaccinated (91.5%), preferred to receive the vaccines at public hospitals (88.6%), and were concerned about vaccine effectiveness (86.9%) and side effects (76.4%), while 61.8% were concerned about vaccine cost. CONCLUSION: Focusing on the personal benefit and relying on the government, physicians, and social role models would make the vaccine advertising campaigns more effective. If annual vaccinations were needed, providing the community with affordable vaccines would be an appropriate, long-term solution to ensure vaccination coverage in low-resource countries like Vietnam. Further studies are needed to examine reasons for the public reference of vaccination centers which may help in improving their confidence in getting the vaccine, regardless of the settings.
