Safety of post-exposure rabies prophylaxis during pregnancy: A follow-up study from Guangzhou, China

Abstract

This study aimed to assess the safety profile of post-exposure prophylaxis (PEP) for rabies in pregnant women. All of the subjects received the Essen vaccination regimen. Systemic and local reactions were monitored within 72 hours following the immunization, and the subjects were followed until six months after delivery. No moderate or severe adverse effects occurred in any subject following the vaccination. Among the 72 subjects in this follow-up study, four had voluntary abortions, one subject had an accidental miscarriage, and the remaining 67 subjects delivered babies vaginally or by caesarean section. All of the infants exhibited normal development.The purified Vero cell rabies vaccine and the purified chick embryo cell vaccine were both safe for the PEP of pregnant women and did not interfere with the development of the fetuses or infants. Education is needed in China to stop pregnancy terminations due to concerns about rabies vaccination risk.
