Insights
Maternal pertussis vaccination during pregnancy is safe for both mother and baby. This immunization strategy protects newborns from pertussis (whooping cough) through antibody transfer.
Area of Science:
- Immunology
- Maternal-Fetal Medicine
- Public Health
Background:
- Newborn infants are vulnerable to pertussis (whooping cough) despite widespread childhood vaccination.
- Maternal pertussis vaccination during pregnancy aims to protect newborns via transplacental antibody transfer.
Purpose of the Study:
- To review the safety and impact of maternal pertussis vaccination on pregnant women, fetuses, and newborns.
Main Methods:
- A systematic review of 27 English language publications from January 1995 to December 2018.
- Searched databases including PubMed/MEDLINE, EMBASE, Scopus, Cochrane, ProQuest, and Science Direct for safety data.
Main Results:
- Maternal pertussis vaccination did not increase local or systemic reactions in pregnant women.
- No safety concerns were identified with repeat or co-administration of tetanus-containing or influenza vaccines.
- Pregnancy, birth, and neonatal outcomes were not adversely affected by maternal pertussis vaccination.
Conclusions:
- Maternal pertussis vaccination during pregnancy is confirmed as safe.
- This vaccination strategy offers a protective measure for newborns against pertussis.
Abstract:
The WHO recommends vaccination of all children against pertussis. However, newborn infants remain vulnerable to infection. Pertussis vaccination during pregnancy has been introduced in several countries to protect newborns via transplacental transfer of maternal pertussis antibodies to the infant. We reviewed the impact of maternal pertussis vaccination on the health of pregnant women, the developing fetus, and health of the newborn. We searched PubMed/MEDLINE, EMBASE, Scopus (Elsevier), Cochrane Database of Systematic Reviews, ProQuest, and Science Direct to identify studies that assessed the safety of maternal pertussis vaccination. Twenty-seven English language publications published between January 1995 and December 2018 were included in this review. Pregnant women receiving pertussis vaccines did not have increased rates of systemic or local reactions. There were no safety concerns with repeat vaccination with other tetanus-containing vaccines or their concomitant administration with influenza vaccines. Maternal pertussis vaccination did not adversely affect pregnancy, birth or neonatal outcomes. This review confirms the safety of maternal pertussis vaccination during pregnancy.
