The first human tests of a possible coronavirus vaccine is underway.
Pfizer and Bio-N-Tech are working together and began testing their vaccine on Monday, May 4th, 2020.
They are trying it on 360 healthy volunteers in the first stage.
If that is successful, they plan to expand it to eight-thousand volunteers in the next stage.
If all goes well there, the vaccine could be ready for the public in months, not years.
