Home > Health Library > Vaccine to Prevent COVID-19
The COVID-19 vaccine can help you avoid getting COVID-19, a disease caused by a type of coronavirus. COVID-19 can cause pneumonia and even death.
You may need 1 or 2 doses of the vaccine. And you might need "booster" doses later to help you stay protected. It takes two weeks after your last dose to be fully protected from COVID-19.
The vaccine prevents most cases of COVID-19. But if you do still catch COVID-19, your symptoms will probably be less severe than if you hadn't gotten the vaccine. You can't get COVID-19 from the vaccine.
Everyone who is able to get the vaccine should get it as soon as possible. The more people who get vaccinated, the better we'll be able to stop the spread of the virus.
The vaccine is extra important for people who are at high risk. This includes people who may be exposed to COVID-19 more often because of their jobs. It also includes people who are at high risk for complications from COVID-19 if they catch it. Some examples of people at high risk include those who:
If you've already had COVID-19, you may still be able to catch it again. Getting the vaccine gives you extra protection.
Getting vaccinated will help protect you from COVID-19. It will also help protect others around you from getting the virus, including people who are more likely to get very sick or die from COVID-19. If you get the virus, you could spread it to friends, family, and other people in your community—including those who are at high risk.
The vaccine is one of the best ways to help the pandemic end sooner so things can return to normal. That means being able to safely go out and see friends and family, meet new people, and do all the things you enjoy. Getting vaccinated can help save lives and help your community thrive.
You might not have side effects. But if you do, they'll probably be like those of other vaccines, including:
This is normal. Your body is building protection against COVID-19.
You may also have other side effects, including:
Side effects will likely go away in a few days. Until then, it may be harder to do your usual activities.
You may need 1 or 2 doses. If you get 2 doses, you may notice side effects more after the second dose.
If you think you've been exposed to COVID-19 or have symptoms like a cough, trouble breathing, or a new loss of smell or taste, call your doctor. These aren't vaccine side effects. You may need a COVID-19 test.
