Key Points:

• RSV immunizations can stimulate an immune response to create antibodies against RSV or can directly give antibodies to an individual
• The RSV vaccine (Abrysvo) for adults can be given to pregnant individuals to provide passive immunity to infants after birth. It should be given at 32-36 weeks of gestational and 2 weeks prior to delivery
• After birth, infants can be given an RSV immunization, either nirsevimab (Beyfortus) or clesrovimab (Enflonsia), which are RSV antibodies. These can be given to all infants less than 8 months old if the pregnant parent did not receive Abrysvo. High risk infants 8-19 months should also receive RSV immunization.
