8 Common Questions About the COVID-19 Vaccine

Here are the answers to some questions and concerns that many people ask.

  • Why should I get a COVID-19 vaccine? It will help protect you, protect others, and end the pandemic. Getting a vaccine will help you avoid catching COVID-19. (If you do catch it, your symptoms will most likely be less severe than if you hadn't gotten the vaccine.) Getting a vaccine also helps you protect the people around you—people who could have serious problems if they catch the virus.

  • Are COVID-19 vaccines safe? COVID-19 vaccines are safe and effective. They have been given to millions of people. The risk of serious problems is very low.

  • Could I get COVID-19 from a vaccine? No, you can't get COVID-19 from a vaccine. The vaccines don't contain the COVID-19 virus, so they can't cause the disease.

  • What are the side effects of COVID-19 vaccines? You might not have any side effects. If you do, they'll probably be a lot like the common side effects of other vaccines—a fever, fatigue, and soreness. (These are signs that your immune system is learning how to fight the virus.) The side effects don't last long, and they can be treated if they bother you.

  • How many doses of a vaccine will I need? You may need 1 or 2 doses of a vaccine. And you might need "booster" doses later to help you stay protected.

  • Do I need a vaccine if I've already had COVID-19? Yes. If you've had COVID-19, you may still be able to catch it again. Getting a vaccine will give you extra protection.

  • Will I still need to wear a mask after I get a vaccine? Maybe. Even if you're fully vaccinated, you may need to wear a mask in indoor public spaces. Be sure to follow all instructions from your local health authorities and the CDC.

  • Why not just get COVID-19 and skip a vaccine? The risk of serious problems from the virus is much higher than the risk of serious problems from a vaccine. COVID-19 is unpredictable. Even if you're young and healthy, you could get very sick, have long-term health problems, or die. So it's much safer to get a vaccine than it is to catch COVID-19.

The COVID-19 vaccines are one of the best to help stop the pandemic. So get vaccinated.
