Coverage Analysis of Complete Basic Immunization (CBI) in Pekalongan District during COVID-19 Pandemic Period with Rapid Card Check Survey in Pandemic Era

The goal of the immunization program is to provide protection from diseases that can be prevented by immunization (PD3I), such as tuberculosis, diphtheria, tetanus, polio, hepatitis B, and measles. Therefore, optimizing the immunization coverage is very important. The coverage of complete basic immunization in Pekalongan District decreased to 88.4% in 2017, while 7 cases of measles were still found. Further, the coverage of immunization has been a challenge in the COVID-19 pandemic situation. The objective of this study was to analyze the complete basic immunization coverage in Pekalongan Regency using Rapid Card Check. This study used an analytic observational design with quantitative and qualitative approaches. Quantitative analysis was performed using chi-square analysis, while in-depth interviews carried out a qualitative analysis to explore further the reasons for not having immunization. The number of samples was 535 toddlers aged 10-26 months. The sample was selected based on random sampling techniques, and data were collected using Rapid Card Check instrument. The coverage of immunization was 71.6%, and only 2.1% did the immunization correctly. Based on the type of antigen, the highest immunization coverage was HB0 = 88.4%, and the lowest was measles = 74.4%. The highest immunization accuracy was the type of antigen HB0 = 85.4%, and the lowest one was Polio4 = 12.0%. The coverage of complete basic immunization in Pekalongan District is still below the national target (95%) in the Covid-19 pandemic era. Therefore, intensive efforts should be made to increase the coverage in the current year.
