Abstract
BACKGROUND Vaccination could provide effective protection against coronavirus disease 2019 (COVID-19). This study aims to describe the COVID-19 vaccination coverage and influential factors in Chinese older hypertensive patients. METHODS Using a cross-sectional design, participants were randomly selected from the electronic health records system during the pandemic era in Hangzhou, China. Logistic regression models were employed to compute the OR and 95% CI in order to assess the relationships between variables and the extent of COVID-19 vaccination coverage. RESULTS As of 3 August 2022, among a sample of 77 970 individuals, 75.11% had completed the full COVID-19 vaccination, while 57.66% had received a booster dose. Disparities in coverage were observed across genders, regions and age groups. Unhealthy lifestyles, cardiovascular disease, cancer, uncontrolled blood pressure, abnormal fasting plasma glucose, dyslipidemia and renal dysfunction were risk factors for COVID-19 vaccination coverage. The coverage rates continuously declined along with the number of risk factors. The ORs for full and booster vaccination in subjects with ≥4 risk factors were 2.55 (2.12∼3.07) and 2.60 (2.16∼3.13), compared to individuals without risk factors. CONCLUSION The COVID-19 vaccination program for older hypertensive patients must be strengthened further. Emphasis should be placed on patients who reside in urban areas, have comorbidities or multiple risk factors.

Public's Willingness to Perform COVID-19 Self-Testing During the Transition to the Endemic Phase in Malaysia - A Population-Based Cross-Sectional Study. Risk Manag Healthc Policy 2023; 16:2505-2519. [PMID: 38024502 PMCID: PMC10676112 DOI: 10.2147/rmhp.s439530] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2023] [Accepted: 11/16/2023] [Indexed: 12/01/2023] Open
Abstract
Introduction Malaysia entered the transition to the endemic phase of Coronavirus 2019 (COVID-19) on 1st April 2022. This study aims to determine the public's willingness to perform COVID-19 self-testing. Factors that influenced their willingness were also assessed. Methods A nationwide, cross-sectional, and population-based study was conducted online in Malaysia from 28th April 2023 to 4th June 2023. Individuals aged 18 years and above were enrolled through the snowball sampling method. Data were analyzed by using the Chi-Square test, independent t-test, and binary logistic regression. Results One thousand four hundred fifty-three responses were included in the analysis. Of these respondents, 89.3% were willing, 4.1% were reluctant, and 6.6% remained hesitant to perform COVID-19 self-testing, The common reasons given by those willing to perform COVID-19 self-testing included being able to self-isolate (99.0%) and seek treatment (96.3%) earlier if tested positive. The common reasons against COVID-19 self-testing included the belief that COVID-19 is equivalent to the common flu (91.7%) and having received the COVID-19 vaccine (78.3%). The isolation policy for COVID-19 was the most significant consideration for those who were still hesitant (85.4%). Women [adjusted odds ratios (OR): 2.1, 95% confidence intervals (95% CI): 1.44-3.00, p < 0.001], individuals with tertiary education (OR: 2.1, 95% CI: 1.32-3.26, p = 0.002), those vaccinated against COVID-19 (OR: 8.1, 95% CI: 2.63-24.82, p < 0.001), and individuals with prior experience of COVID-19 self-testing (OR: 4.2, 95% CI: 2.84-6.12, p < 0.001) showed a significantly higher willingness to engage in COVID-19 self-testing. Conclusion The public exhibited a high willingness to perform COVID-19 self-testing during the transition to the endemic phase in Malaysia. Future strategies to promote COVID-19 self-testing uptake in Malaysia should focus on vulnerable groups, address the common concerns among those hesitant and reluctant, and highlight the advantages of COVID-19 self-testing.

Opinions, Attitudes and Factors Related to SARS-CoV-2 Vaccine Uptake in Eight South American Countries. Vaccines (Basel) 2023; 11:1660. [PMID: 38005992 PMCID: PMC10675814 DOI: 10.3390/vaccines11111660] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Revised: 10/09/2023] [Accepted: 10/20/2023] [Indexed: 11/26/2023] Open
Abstract
This article presents attitudes and practices regarding COVID-19 vaccination in the South American population. The study collected data from a self-administered survey distributed through social media platforms between February and April 2022 (N = 6555). The survey included questions related to participants' sociodemographic background, flu vaccination practices, sources of information about COVID-19, and opinions regarding pandemic management and vaccination against SARS-CoV-2. The respondents agreed with the statement that COVID-19 vaccines were necessary (86.4%), effective (79.8%), safe (79.1%), and should be mandatory (64%). Overall, 83.4% accepted vaccination and 12.3% refused it completely. Main rejection reasons were safety (65.8%) and efficacy (54.9%) issues, and rushed development and approvals (49.1%). Vaccine uptake was associated with being ≥60 years, being a healthcare worker, previous influenza vaccine uptake, adherence to preventive measures, the death of ≥1 close people from COVID-19, and being informed through mass media or health authorities' channels. Vaccine uptake inversely correlated with male gender, low educational level, and use of closed social networks for COVID-19 information purposes. This study provides valuable insights into COVID-19 vaccination attitudes and practices in South America that may be used to promote vaccine uptake in the region. Higher COVID-19 vaccination acceptance among people with previously acquired prevention habits reinforces the importance of routine health promotion strategies.

Vaccines (Basel) 2023; 11:1272. [PMID: 37515086 PMCID: PMC10386099 DOI: 10.3390/vaccines11071272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Revised: 07/10/2023] [Accepted: 07/19/2023] [Indexed: 07/30/2023] Open
Abstract
We used three rounds of a repeated cross-sectional survey on COVID-19 vaccination conducted throughout the entire territory of Yemen to: (i) describe the demographic and socio-economic characteristics associated with willingness to be vaccinated; (ii) analyse the link between beliefs associated with COVID-19 vaccines and willingness to be vaccinated; and (iii) analyse the potential platforms that could be used to target vaccine hesitancy and improve vaccine coverage in Yemen. Over two-thirds of respondents were either unwilling or unsure about vaccination across the three rounds. We found that gender, age, and educational attainment were significant correlates of vaccination status. Respondents with better knowledge about the virus and with greater confidence in the capacity of the authorities (and their own) to deal with the virus were more likely to be willing to be vaccinated. Consistent with the health belief model, practising one (or more) COVID-19 preventative measures was associated with a higher willingness to get a COVID-19 vaccination. Respondents with more positive views towards COVID-19 vaccines were also more likely to be willing to be vaccinated. By contrast, respondents who believed that vaccines are associated with significant side effects were more likely to refuse vaccination. Finally, those who relied on community leaders/healthcare workers as a trusted channel for obtaining COVID-19-related information were more likely to be willing to be vaccinated. Strengthening the information about the COVID-19 vaccination (safety, effectiveness, side effects) and communicating it through community leaders/healthcare workers could help increase the COVID-19 vaccine coverage in Yemen.

[PMID: 37376498 DOI: 10.3390/vaccines11061109] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 06/04/2023] [Accepted: 06/13/2023] [Indexed: 06/29/2023] Open
Abstract
Achieving a high level of COVID-19 vaccination coverage in a conflict-affected setting is challenging. The objective of this paper is to shed further light on the main determinants of vaccination coverage using a large, cross-sectional sample (October-November 2022) of over 17,000 adults in Syria. We find evidence that certain demographic and socioeconomic characteristics describe a core set of vaccination personas. Men, older respondents, and those who are more educated and trust information received from healthcare authorities are more likely to be vaccinated. Healthcare workers in this sample are highly vaccinated. Furthermore, respondents with more positive views towards COVID-19 vaccines are also more likely to be willing to be vaccinated. By contrast, respondents who believe that vaccines are associated with significant side effects are also more likely to refuse vaccination. In addition, younger respondents and women, as well as those with a lower level of education, are more likely to refuse to be vaccinated. Respondents with a neutral attitude towards vaccines are also more likely to be undecided, whereas respondents who are refusing to get vaccinated are more likely to trust the information received from private doctors, private clinics, as well as social media and, more broadly, the internet.
