Abstract

Age is an independent risk factor for COVID-19. Thus, the government of Indonesia prioritizes the elderly and adults with significant comorbidities for COVID-19 vaccination. To discover whether this policy is still appropriate, we evaluated the effects of vaccination against the COVID-19 incidence and infection risk.It was a retrospective cohort study of the NAR COVID-19 and Dashboard KPCPEN COVID-19 of the Depok City Health Department. The tests used to analyze the data were the chi-square and logistic regression tests. We discovered that there was a 92.7% total reduction in the COVID-19 infection rate with vaccination. The infection risk for COVID-19 in vaccinated people aged ≥ 60 years was far lower than those who were unvaccinated (RR = 0.10 vs. 1.72). In conclusion, vaccination reduces the transmission of COVID-19 significantly, especially in the ≥ 60 years age group. It affirms that the age priority policy in the vaccination policy is still applicable and does not require any amendments.

Abstract

Vaccination is a disease prevention method recommended by the WHO as it will reduce disease severity, mortality rate and risks. The objective of this study is to discover the impact of COVID-19 vaccination against COVID-19 mortality rate in Indonesia. This was a retrospective cohort research on the data from the NAR COVID-19 database and the KPCPEN COVID-19 Dashboard of the Depok City Health Department from May 2020-February 2023. We performed a Cox proportional hazard analysis to obtain the risk for death. We discovered that COVID-19 vaccination reduced the mortality until it was less than 10% of unvaccinated population (0,24% for vaccinated vs. 2,5% for unvaccinated). We found that vaccination reduced the risk of death for COVID-19 patients to 91% (AHR=0.09; 95% CI = 0.07-0.11; p
