“The US Food and Drug Administration has approved the world’s first vaccine for chikungunya, which it sees as an ’emerging global health threat.’ The mosquito-borne disease causes fever and joint pains and can be fatal to newborns.

The FDA’s approval is expected to speed up the vaccine’s global rollout.  This year, about 440,000 chikungunya cases, including 350 deaths, have been reported as of September.”
