US advises older adults to avoid the chikungunya vaccine

The CDC and FDA advise against Ixchiq chikungunya vaccine for American travellers aged 60 and above. This is due to reported heart and brain-related issues post-vaccination. The advisory follows investigations into cases in the US and other countries. US advisors suggest Bavarian Nordic's Vimkunya vaccine as an alternative for travellers 12 and older.
