摘要
Background:Vaccination is crucial for human immunodeficiency virus(HlV)-exposed children because of their increased risk of morbidity and mortality from various vaccine-preventable diseases.However,studies have shown that they are at high risk of incomplete vaccination.Although China has developed prevention of mother-to-child transmission(PMTCT)of HIV programs substantially over the past decades,few studies have investigated the immunization levels of Chinese HIV-exposed children.Therefore,we aimed to evaluate vaccination coverage and its associated factors among HIV-exposed children in China during 2016-2018.
