New research suggests that getting the respiratory syncytial virus (RSV) vaccine earlier in pregnancy, closer to 32 weeks, provides the best protection for newborns against RSV. Maternal vaccination at least 5 weeks before delivery leads to more efficient transfer of antibodies to the newborn. The study found that RSV antibody levels were higher and longer-lasting in vaccinated mothers and their babies. This information can help guide physicians in advising pregnant patients on the best timing for RSV vaccination. Additional research is needed to determine the minimum antibody levels needed to protect infants and the potential benefits of breastmilk from vaccinated mothers.
