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

Bahasa Abstract

Vaksinasi adalah salah satu cara pencegahan penyakit yang direkomendasikan oleh WHO, karena akan mengurangi derajat keparaha npenyakit, tingkat mortalitas, dan risiko mortalitas. Tujuan penelitian ini adalah untuk mengetahui dampak vaksinasi COVID-19 terhadap tingkat mortalitas COVID-19 di Indonesia. Data didapat dengan melakukan kohort retrospektif terhadap database NAR COVID-19 dan dashboard KPCPEN COVID-19 di Dinkes Koat Depok dari Mei 2020 hingga Februari 2023. Peneliti melakukan analisis Cox proportional hazard untuk mendapatkan nilai risiko kematian. Kemudian, ditemukan bahwa orang yang divaksinasi COVID-19 memiliki tingkat mortalitas yang hanya sepersepuluh dari oragn yang tidak divaksinasi (0.24% vs 2.5%). Sehingga vaksinasi COVID-19 dapat menurunkan mortalitas COVID-19 hingga 91%. (AHR=0.09; 95% CI = 0.07-0.11; p
