CDC and FDA urge travelers aged 60+ to reconsider the chikungunya vaccine advisory due to emerging concerns over severe side effects.
What Happened: CDC and FDA Issue Caution for Chikungunya Vaccine
In a crucial update for international travelers, U.S. health authorities have advised that adults aged 60 and older should avoid receiving the Ixchiq chikungunya vaccine. This chikungunya vaccine advisory, jointly issued by the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA), comes in response to reports of serious side effects—including neurological and cardiac complications—in elderly recipients.
This travel health advisory affects individuals planning visits to regions where chikungunya is endemic, such as parts of South America, Africa, and Southeast Asia.

Background: FDA’s Approval of Ixchiq and Emerging Concerns
Approved by the FDA in late 2023, Ixchiq was the first-ever chikungunya vaccine, developed by French company Valneva and designed for adults traveling to areas with high transmission risk. Early trials demonstrated a 98.9% seroresponse rate—a promising statistic.
However, recent follow-up reports raised red flags due to this chikungunya vaccine advisory, particularly in older adults. At least six individuals over 65 experienced heart inflammation and neurological symptoms within days of vaccination. This has led European health regulators to initiate their own reviews of the vaccine’s safety.

Expert Analysis: Voices Behind the Advisory
A CDC advisory panel reviewed available data and found enough evidence to recommend caution for those 60 and older. While younger travelers are still advised to consider vaccination before visiting high-risk regions, seniors should discuss alternative precautions with their doctors.
Additionally, the panel suggested expanding access to a second chikungunya vaccine, Vimkunya, currently under consideration. This recombinant vaccine does not use a live virus and forms part of broader chikungunya vaccine advisory discussions, potentially offering a safer alternative for vulnerable groups.
Meanwhile, internal policy debates have intensified. William “Reyn” Archer III, an aide to U.S. Health Secretary Robert F. Kennedy Jr., recently questioned whether “enough clinical trial data” exists to back the vaccine’s broad rollout, signaling possible regulatory recalibrations.

Implications: What It Means for Older Travelers
This advisory isn’t just a medical update—it’s a public health signal. For older adults planning trips to tropical destinations, the risks associated with the Ixchiq vaccine may outweigh the benefits, especially if the traveler has existing heart or neurological conditions.
Instead, healthcare providers are urging a return to preventive basics:
- Use mosquito repellents with DEET or picaridin
- Wear long-sleeved clothing
- Stay in screened or air-conditioned spaces
- Consider travel postponement if high risk persists
According to AP News, older adults experienced the majority of complications from the vaccine within the first week of injection.
Next Steps: Awaiting CDC’s Final Decision
Although the CDC’s advisory panel has made its recommendation, the agency has not yet officially updated its travel vaccination guidelines. A revised guideline is expected soon, which could include:
- Contraindications for certain age groups
- Monitoring programs for adverse reactions
- Greater public education campaigns
Until then, elderly travelers and their healthcare providers must make vaccination decisions case by case, considering both destination risk and personal health status in light of the chikungunya vaccine advisory.

Why This Story Matters
With global travel returning to pre-pandemic levels, this advisory could shape how older adults approach tropical travel. It also reignites discussions around vaccine oversight, age-specific risks, and the ethical responsibilities of public health agencies in launching new products.
