US health officials advise older travelers not to get a chikungunya vaccine
- The FDA and CDC advised U.S. Travelers age 60 and older to temporarily stop receiving Valneva's Ixchiq chikungunya vaccine on May 9, 2025, amid safety concerns.
- This recommendation comes after reports of severe health complications, such as neurological and cardiac issues, primarily affecting individuals aged 62 and older with preexisting conditions, which have resulted in multiple hospitalizations and two fatalities.
- Ixchiq, approved in November 2023, contains a weakened chikungunya virus and has been distributed worldwide with about 80,000 doses administered, while chikungunya causes fever and joint pain via mosquito bites.
- As of May 7, 2025, 17 serious global adverse event reports, including neurological and cardiac symptoms, have been tracked, leading U.S. Advisors to issue a precaution for older adults and European regulators to review the cases.
- The FDA is currently reevaluating the benefit-risk profile of the Ixchiq vaccine for individuals aged 60 and above, while Bavarian Nordic’s Vimkunya has been suggested as an alternative option for travelers aged 12 and older.
