Vaccine Advisory Panel Calls for Expanded Protection Against RSV, Meningitis, and Chikungunya

A panel of federal health experts has recommended broadening vaccine options for several infectious diseases, including respiratory syncytial virus (RSV), meningitis, and chikungunya, a mosquito-borne illness. The Advisory Committee on Immunization Practices (ACIP) suggested new guidelines for vaccine use, which inform the Centers for Disease Control and Prevention (CDC) recommendations, although recent organizational changes at the CDC may influence the implementation process.

The updated recommendations include offering the RSV vaccine to adults aged 50 to 59 who have underlying health conditions such as heart disease, diabetes, or chronic obstructive pulmonary disorder. Additionally, a new combined vaccine developed by GSK was endorsed; it protects against five strains of meningococcal bacteria, some of which have previously caused outbreaks on college campuses.

For travelers, a second chikungunya vaccine was recommended for those aged 12 and older heading to countries experiencing active outbreaks. This is particularly relevant as approximately 100 to 200 cases of chikungunya are reported annually among U.S. travelers.

Furthermore, a safety warning was issued for an older chikungunya vaccine that employs a weakened live virus. Individuals aged 65 and above are advised to discuss potential risks with their healthcare providers, especially if they have additional health conditions, following reports of heart or brain-related symptoms shortly after vaccination. These cases are under investigation.

It's important to note that vaccine recommendations are typically approved following these advisories. However, the recent leadership uncertainties at the CDC have introduced some complexities. Acting CDC Director Susan Monarez, appointed during the transition period, has recused herself from vaccine-related decision-making until her confirmation is finalized. Meanwhile, decisions may be influenced by U.S. Health Secretary Robert F. Kennedy Jr., known for his skepticism towards vaccines.
