Study suggests RSV vaccine given at 32 weeks of pregnancy may better protect newborns.
Researchers from Mass General Brigham found that giving the RSV vaccine earlier in pregnancy, around week 32, provides better protection for newborns by enhancing the transfer of maternal antibodies.
This is earlier than the current guideline of weeks 32-36.
The study, published in the American Journal of Obstetrics & Gynecology, suggests that vaccinating earlier in pregnancy could be more effective, though further research is needed to determine the minimum antibody levels required for protection and the additional benefits from breastmilk.
