Description:Background:
Major birth defects are important infant outcomes that have not been well studied in the post-marketing surveillance of vaccines given to pregnant women. We assessed the presence of major birth defects following vaccination in the Vaccine Adverse Event Reporting System, a national spontaneous reporting system used to monitor the safety of vaccines in the United States.
Methods:
We searched the VAERS database for reports of major birth defects during 1/1/1990 through 12/31/2014. We excluded birth defects from vaccines that had been studied in pregnancy registries or other epidemiological studies.
Results:
We identified 50 reports of major birth defects; in 28 reports, the vaccine was given during the first trimester. Birth defects accounted for 0.03% of all reports received by VAERS during the study period; reported defects affected predominately the musculoskeletal (N=10) or nervous (N=10) systems. No unusual clusters or specific birth defects were identified after any vaccine evaluated.
Conclusion:
This review of the VAERS database found that major birth defects were infrequently reported, with no particular condition reported disproportionally.
