The Importance of RSV Vaccines for Pregnant Women and Older Adults

Two RSV vaccines, Arexvy and Abrysvo, have been approved for people aged 60 and older, with Abrysvo also approved for pregnant women. RSV is a common virus that can cause serious illness, particularly in infants and older adults. The vaccines use specific viral proteins to stimulate a targeted immune response. Common side effects include swelling or pain at the injection site, fever, headache, nausea, diarrhea, and muscle or joint pain. Some participants in clinical trials reported developing inflammatory conditions, but it's unclear if the vaccines caused them. The CDC recommends vaccination for those at the highest risk for severe RSV, and it's possible to get the RSV vaccine alongside the COVID and flu vaccines, but further research is needed on their interactions.
