Abstract

Vaccination is a strategy to control the COVID-19 pandemic and holds a crucial impact on global health. A better understanding of factors associated with vaccination is needed to establish a good vaccination program in a population. The purpose of this study is to analyze COVID-19 vaccination program data based on regional status and day type in the West Java Province of Indonesia and contribute to discovering other characteristics of the COVID-19 vaccination program. This study is a cross-sectional study using secondary data (N = 7922) from West Java's COVID-19 Information and Coordination Center (PIKOBAR) from January to November 2021. Independent t-test with an alternative non-parametric Mann-Whitney U test (p-value < 0.05) is used as a statistical test in this study. The result reported significant differences in vaccination coverage between the city area and the regency area (p < 0.001). Significant differences in vaccination on working day and holiday were also found in both settings (p < 0.001). Vaccination was confirmed to be higher in the city compared to the regency and decreased on holiday compared to the working day. In conclusion, factors linked to regional status and day type must be considered as important factors for developing and accelerating vaccination programs.

Keywords: COVID-19; day type; regional status; vaccination program.

Total of second dose COVID-19 vaccination number and vaccination coverage in West Java as of 23 November 2021. The map color represents vaccination coverage and the box color represents regional status; pink for regency areas and yellow for city areas. A statistical test was carried out to analyze the significant difference in vaccination numbers and vaccination coverage between the city and the regency. The result of the Saphiro–Wilk normality test has shown that the vaccination number data in the two regions are not normally distributed (p < 0.05), whereas vaccination coverage data are normally distributed (p > 0.05). The statistical test used in Table 2 and Table 3 is adjusted to the result of the normality test.
