New Hope for Babies: Safe RSV Protection for All

USA, AtlantaMon Oct 20 2025

A recent study has brought good news for parents worried about RSV in their little ones. It turns out that babies can get an antibody shot to protect them from RSV, even if their moms were vaccinated during pregnancy. This shot, called nirsevimab, is a big deal because RSV is a common and serious respiratory infection for infants.

Study Details

The study looked at 181 pairs of moms and babies from hospitals across the United States. They found that all groups of babies had high levels of antibodies against RSV, no matter how they got their protection.

  • Some moms were vaccinated during pregnancy.
  • Some got the shot for their babies after birth.
  • Some did both.

The important thing is that all these methods worked well together.

Key Findings

  • Babies who got both the maternal vaccination and the antibody shot had no serious side effects.
  • The antibody shot was especially effective for babies whose moms weren't vaccinated during pregnancy.
  • Their protection increased by 25 times.
  • Compared to a three-fold increase for those whose moms were also vaccinated.

Ongoing Research

This research is ongoing, and scientists will continue to study:

  • How long the protection lasts.
  • How breast milk plays a role.

It's part of a growing body of evidence that shows how safe and effective these immunizations are. With respiratory illness season coming up, this news gives parents more confidence in protecting their little ones.

questions

    Can nirsevimab be used to protect babies from the evil cackling of their older siblings during flu season?
    How do the findings of this study compare to previous research on the safety and efficacy of nirsevimab?
    How effective is nirsevimab in preventing RSV hospitalization in infants whose mothers were vaccinated during pregnancy?
