A federal panel of experts on Wednesday recommended an expansion of RSV vaccinations for adults and a new combination shot as another option to protect teens against meningitis.

The Advisory Committee on Immunization Practices also voted to recommend a shot to protect travelers from a mosquito-borne illness called chikungunya.

But it’s not clear who will decide whether to accept those recommendations.
