COVID-19 Update: Vaccines arrive, bringing new questions

As the COVID-19 vaccine starts becoming more available, University Health Chief Medical Officer Dr. Bryan Alsip answers a new set of frequently asked questions about how it works, how long it lasts, and when we can take off our masks (not quite yet).

• How much protection does a first shot give?
• How soon do you start developing immunity after the first shot?
• What do I do if I feel bad after getting the vaccine?
• What happens if I don’t get my second shot?
• What happens if the second dose is delayed for some reason?
• Is the booster different from the initial dose?
• Do we know how long the vaccine protection lasts?
• Could I get a different vaccine if that’s available when time comes for my second shot?
• Should pregnant women receive the vaccine?
• Should I get the vaccine even if I’ve already had COVID-19?
• When I am vaccinated can I quit wearing a mask?
• If I and my friends are all vaccinated, can we go without masks with each other?
• Does the vaccine prevent the illness or just symptoms?
