Biden noted that in the next few weeks, American experts will be able to determine how easily this disease spreads, how dangerous it is, what harm it causes, and are capable of does the vaccine handle it.

It can affect a large number of people around the world, including those who have recovered from other strains of coronavirus, and existing vaccines may not be effective.
