“…Immunization is one of the preventative measures to spread the disease to other regions, which has proven to be very cost-effective (Darrah et al, 2020;Gheibi Hayat & Darroudi, 2019). Immunization activities are expanded into an immunization development program in the context of preventing the transmission of several diseases that can be prevented by immunization, namely tuberculosis, diphtheria, pertussis, measles, polio, tetanus, and hepatitis B. Immunization is an effort to prevent infectious diseases which are one of the priority activities of the Ministry of Health as a tangible form of government commitment to achieving Sustainable Development Goals (SDGs), significantly to reduce child mortality (Ashari, 2021;Shell, 2018) Based on data from the World Health Organization (WHO) in 2014, infant mortality due to infectious diseases that should have been prevented by immunization is still high. An estimated 2-3 million deaths per year globally have been successfully prevented from diphtheria, measles, pertussis, pneumonia, polio, rotavirus diarrhea, rubella, and tetanus through immunization (Bangura et al, 2020;Darrah et al, 2020).…”
