It’s likely people are trying to spend more time outside this summer, whether to avoid indoor situations where COVID-19 may spread or just for enjoyment.

Q. Will we have a vaccine to prevent COVID-19 and, if so, when?

A. I'm optimistic because never in human history has so much scientific time and effort been spent trying to make a vaccine. But it won't it be easy. As fast as possible, the vaccine scientists need to prove, first, that a vaccine is safe (minimal side effects) and, second, that it works to reduce a person's risk of getting the disease. Then they need to produce enough of it to immunize most of the 7.6 billion people on earth. Doing all of this within two to three years of a new virus being discovered would be an unprecedented achievement.
