On April 16, 2025, the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices (ACIP) updated their recommendations for respiratory syncytial virus (RSV), meningitis, and chikungunya vaccines. ACIP recommended that at-risk adults 50 years and older receive a single dose of FDA-approved RSV vaccines, including Pfizer’s Abrysvo or GSK’s Arexvy, for the prevention of RSV infection. RSV is a respiratory virus that can lead to lung infections, pneumonia and hospitalization in infants or older adults. Individuals with weakened immune systems or chronic heart or lung disease are at the highest risk for severe RSV infections. The new recommendation from ACIP expands on the age range for RSV vaccination. Previously, the vaccine was recommended for adults over age 75 and at-risk adults 60-74 years.
ACIP panel also recommended the use of GSK’s new pentavalent meningococcal vaccine, Penmenvy, along with Pfizer’s Penbraya for healthy individuals ages 16–23 and for individuals ages 10 and older who are at increased risk of meningococcal disease. Individuals with HIV infection, a weakened immune system or who do not have a spleen are among those that have the highest risk of meningococcal disease.
Bavarian Nordic’s Vimkunya is FDA approved for prevention of disease caused by mosquito-borne chikungunya virus. ACIP recommends vaccination for travelers and laboratory scientists who work on the chikungunya virus. Valneva’s Ixchiq, an alternative chikungunya vaccine, is also recommended for travelers, but there is additional need for precaution for individuals aged 60 and older due to potential cardiac and neurological events. Due to this, on May 9, 2025, the FDA and CDC issued a recommendation that Ixchiq not be given to patients 60 years and older until a new risk-benefit assessment can be completed based on post-marketing safety reports.
