RSV Immunizations: Protecting Babies from Respiratory Syncytial Virus

Understanding RSV Immunizations for Babies

Respiratory syncytial virus (RSV) infects nearly all children by the age of 2. It is particularly dangerous for infants and is the leading cause of hospitalization for those under 1 year old. RSV can lead to serious breathing problems.

RSV infections typically peak from late fall to early spring, with the season mostly running from October to March in the U.S. Pediatricians recommend that babies born during this time receive immunizations to prevent severe RSV infections.

Types of RSV Immunizations

There are two options for RSV immunization:

  1. Immunization During Pregnancy: Pregnant women can receive the Abrysvo vaccine, which is given between 32 and 36 weeks of pregnancy. This helps pass antibodies to the baby, offering protection for about six months after birth.

  2. Nirsevimab for Infants: This immunization is for infants under 8 months during RSV season. It is also available for some children aged 8 to 19 months who are at higher risk. This shot provides immediate protection against RSV for at least five months.

If a mother had the RSV vaccine while pregnant, her baby will have protection for the upcoming RSV season. However, if the baby is born less than 14 days after the vaccination, they may need the nirsevimab shot.

Conclusion

To protect infants from RSV, expectant mothers should consider vaccination during pregnancy, and newborns should receive the nirsevimab shot as needed. These measures help ensure infants remain healthy during the RSV season.
