The following paragraph was published today in USA Today regarding Covid 19 Vaccine development:

A safe and effective vaccine candidate? Yes please

A coronavirus vaccine candidate being developed at the University of Oxford is safe and effective and has few side effects, early trial results show. The vaccine, AZD-1222, led to strong immune responses for nearly two months in a trial that continues to track more than 1,000 healthy adults, according to a paper published Monday in the Lancet. A second study published Monday showed 95% of volunteers who received a high dose of a Chinese vaccine candidate and 91% of those who received a low dose showed an immune response 28 days after the shot. So, more good news on the vaccine front. Seventeen candidate vaccines are being tested in people around the world.
