The FDA’s decision follows evaluation, including two clinical trials involving 3,500 participants in North America.

Ixchiq operates on a live, weakened version of the chikungunya virus, an approach in vaccine development.

The vaccine’s efficacy and safety were assessed in clinical trials, with common side effects reported, including headache, fatigue, muscle and joint pain, fever, and tenderness at the injection site.

Serious reactions were reported in a small percentage of recipients, addressing the importance of ongoing monitoring.
