Chikungunya virus: "What happens is that people come back from the Caribbean to Florida with virus in their blood". There's no treatment for chikungunya, and no vaccine, though researchers are working on that. http://buff.ly/1pcekVS

How do vaccines work? TED-Ed video

The first ever vaccine was created when Edward Jenner, an English physician and scientist, successfully injected small amounts of a cowpox virus into a young boy to protect him from the related (and deadly) smallpox virus.
