Pregnancy reduces COVID-19 vaccine immunity against novel variants

13 Aug 2025

Abstract excerpt

Pregnant women are at heightened risk for severe outcomes from infectious diseases like COVID-19, yet were not included in initial vaccine trials, which may contribute to low booster uptake (15% or lower). We explored the serological and cellular responses to COVID-19 mRNA booster vaccines (i.e., ancestral and BA.5) in pregnant and age-matched, non-pregnant females to identify how pregnancy affects immunity...
