Millions of people have already gotten the vaccine and there have been almost no red flags. If you are allergic to a lot of things or carry an epi-pen tell them they will watch you for a longer period of time.

They are already working on boosters that will cover some of the recent mutations. Everyone may have to get a shot this fall to keep ahead of the mutations.
