“…The immunization program aims to provide protection from diseases that can be prevented by immunization (PD3I), such as tuberculosis, diphtheria, tetanus, polio, hepatitis B, and measles [21]; however, in Pekalongan District, cases of measles had been found, as, in 2015, the number of measles cases found was 0 cases, but in 2016, it increased to 171 cases although in 2017 it drops to 7 cases [22]. Immunization coverage has also been a challenge in the COVID-19 pandemic situation [23][24][25][26]. As physical distancing policy applies during the COVID-19 pandemic period, the implementation of health services has been severely affected by temporary closure and/or postponement of immunization services at the integrated service pos (posyandu) and community health center (puskesmas) in many areas.…”
