Is HPV vaccination in pregnancy safe?

Area of Science:

• Immunology
• Vaccinology
• Obstetrics & Gynecology

Background:

• Millions of HPV vaccine doses administered globally.
• Fertile women of childbearing age are primary recipients.
• Inadvertent vaccination during early pregnancy can occur.

Purpose of the Study:

• To investigate the safety of HPV vaccination during pregnancy.
• To assess potential fetal adverse events following inadvertent HPV vaccination.
• To review existing literature on HPV vaccine and pregnancy outcomes.

Main Methods:

• Systematic literature search of PubMed and Embase.
• Inclusion of English-language studies published within the last 10 years.
• Analysis of evidence related to fetal adverse events, particularly spontaneous miscarriage.

Main Results:

• No significantly increased rate of spontaneous abortion found in overall analyses.
• Evidence primarily focused on spontaneous miscarriage as a fetal adverse event.
• No indication of other HPV vaccine-associated adverse events in pregnancy or post-conception.

Conclusions:

• HPV vaccination during pregnancy does not appear to increase the risk of spontaneous abortion.
• Current evidence suggests no significant adverse fetal outcomes associated with inadvertent HPV vaccination in early pregnancy.
• Further research may be warranted to confirm safety profiles for specific HPV vaccines.
