Abstract:
COVID-19 infection among patients with chronic diseases is strongly correlated with severe illness and death. The purpose of this study was to assess the acceptance of COVID-19 full dose vaccination and identify related factors among adults with chronic diseases. A cross-sectional online survey was conducted between September and November, 2022. The sample was 300 adults with chronic diseases(ages 35-59) who registered for the care at chronic disease out-patient clinic at three secondary government hospitals by simple random sampling. E-questionnaires were used to collect personal information, knowledge COVID 19 and COVID19 vaccine, and to assess health perceptions including 1) perceived susceptibility of COVID -19 infection, 2) perceived severity of the COVID-19, 3) perceived barriers of COVID-19 vaccine, 4) perceived benefits of the COVID-19 vaccine, and advice from medical professionals. The coefficients KR-20 and Cronbachs alpha coefficients were 0.74, 0.77, 0.86, 0.91, 0.91, and 0.91 respectively. Data were analyzed by using descriptive statistics and binary logistic regression. The results showed that 86.3 percent of respondents were most accepting of COVID-19 vaccinations. The factors significantly associated with the acceptance of the COVID-19 full dose vaccination among adults with chronic diseases were income [Odds ratio (OR) =4.65,95%CI=1.894-11.459], perceived susceptibility of COVID -19 infection (OR=2.07,95%CI=1.048-4.094), perceived benefits of the COVID-19 vaccine (OR=3.51,95%CI=1.791-6.914) and advice from medical professionals (OR=2.68,95%CI=1.349-5.360) The results of this research suggest that acceptance of a COVID-19 vaccine was highly influenced by perceived susceptibility of COVID 19 and safety and efficacy of COVID 19 vaccine. To improve covid19 vaccine coverage, governments and medical professionals should improve communication and increase trust, especially in population with chronic disease and low income to accept a vaccine.
