Implementation Model of Acceptance of Covid-19 Booster Vaccine in Elderly in Bogor City

Objective: The major impact of COVID-19 occurs especially on the elderly, however the vaccination achievement rate among them tends to be low. The COVID-19 vaccination strategy for the elderly must still be implemented even though WHO has been revoked the Public Health Emergency of International Concern (PHEIC) status for COVID-19. One approach that can be taken is to empower the elderly in the vaccination process. This research aims to see the effectiveness of changes in knowledge, attitudes and behavior of the elderly regarding acceptance of the COVID-19 vaccine after receiving educational intervention using modules using the peer group method. Method: Quasi-experiment with a one-group pretest-posttest pattern. The research was conducted at the North Bogor Community Health Center in April-June 2023 on 66 elderly people taken using a purposive sampling technique. The questionnaire is used to look at characteristics, vaccine history, assess respondents' knowledge, attitudes and behavior regarding the COVID-19 situation. Data collection went through three stages, namely pre-test distribution, peer group method using module-19 and post-test distribution. Bivariate analysis with dependent t-test using SPSS 23.0 software. Results: The majority of elderly people were aged 60-74 years (90.9%) and there was a significant increase (p<0.05) in the average score of knowledge, attitudes and behavior of elderly people before and after being given the intervention. The average knowledge score before intervention was 69.60 ± 9.51 and after intervention 80.30 ± 10.29, attitude score before intervention 80.43 ± 9.61 and after intervention 85.25 ± 11.99, and behavior score before intervention 86.29 ± 14.67 and after intervention 90.35 ± 10.34. Conclusion: implementation of the model with intervention modules is effective in increasing knowledge, attitudes and behavior. It is hoped that with this increase, elderly people will be able to receive the COVID-19 vaccine.
