Is Your Baby Protected Against RSV?
RSV SEASON • LATE SUMMER → WINTER
RSV is the leading cause of hospitalization in U.S. infants — and most babies who end up hospitalized were previously completely healthy. The good news: protection is simple, and your baby only needs one of two options, not both.
The two options
Option 1: A vaccine during pregnancy
Given between weeks 32–36 of pregnancy, this option passes protective antibodies to your baby before birth, covering them through the riskiest early months.
Option 2: An antibody shot for your baby after birth
A single dose given directly to your newborn offers strong protection through RSV season, regardless of whether the pregnancy vaccine was received.
Either option offers strong protection through the months when RSV risk is highest. Which one makes sense depends on timing — when you’re due, when RSV season starts, and your own health history.
Why it matters
RSV spreads easily, especially once older siblings are back in school or daycare and bringing it home. Most infants who catch RSV have mild, cold-like symptoms — but a meaningful number end up needing hospital-level care, particularly babies under 6 months.
What to do next
RSV season is approaching. If you’re currently pregnant, this is a conversation worth having with your OB before week 32. If you already have a newborn at home, ask about the antibody shot at your next pediatric visit.
If you’re still deciding on a pediatrician for the season ahead, I’d love to meet you and talk through what makes sense for your family.
