There are already several SARS-CoV-2 vaccines in human trials. The first one (from Moderna) was administered in Seattle in a few humans around 2 months ago (and the signs seem to be good). Since then, the Oxford vaccine has gone in human trials, as has gone a vaccine in China. Likely, there are other vaccines in human trials.
Moderna is soon staring Phase 2 trials, and already got licensed for Phase 3 (expected to start on the summer). With a bit of luck, the medical service might get vaccinated before Christmas, though more realistically it is gonna happen early next year. If everything goes right, obviously.
