Drugmakers are racing to get a vaccine for the coronavirus approved this year, an ambitious goal considering the number of safety tests and trials a vaccine must pass before the public can access it.

A possible vaccine for the 2019 novel coronavirus, which has infected over 17,000 and killed at least 360 since late 2019, is stored in a laboratory refrigerator in Houston, Texas. It was first developed for a different coronavirus, SARS, in 2012, but researchers think it could be just as effective in 2020.
