Pregnancy

An RSV vaccine during pregnancy protects your baby from the day they’re born — right when RSV is most dangerous.

Why it matters before birth.

  • RSV is the leading cause of infant hospitalization in the U.S.
  • Newborns are most at risk in their first months
  • Protection from pregnancy covers those first months
  • Your baby can also be protected with an antibody after birth

Timing at a glance

  • Weeks 32–36 of pregnancy
  • During RSV season (fall and winter)
  • One vaccine — not repeated in later pregnancies
  • Later babies get the antibody instead
Protection

How protection works.

01

Vaccine during pregnancy

One dose at 32–36 weeks, during RSV season. Your antibodies pass to your baby.

02

Or an antibody after birth

If you didn’t get the vaccine, your baby can get a preventive antibody instead.

03

Usually one or the other

Most babies need only one. Your provider will help you choose what fits.

Your options

What’s available — and where to get it.

Every option CDC recommends, listed alphabetically. Talk with your provider about which is right for you.

During pregnancy — weeks 32 to 36, in RSV season

One dose of the maternal RSV vaccine. Protection passes to your baby.

If you get it at least 14 days before birth, most babies won’t need the antibody.

Babies under 8 months, in their first RSV season

One dose of a preventive antibody — if the mother didn’t get the RSV vaccine in pregnancy.

Best given before leaving the birth hospital, or in the first week of life if born during RSV season.
