8 Common Questions About COVID-19 Vaccines

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

Why should I stay up to date on my COVID-19 vaccines? It will help protect you and protect others. Staying up to date will help protect you from getting very sick from COVID-19. If you catch it, your symptoms will most likely be less severe than if you hadn't gotten the vaccine. And you are less likely to need to be in the hospital. Staying up to date 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 billions 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, feeling very tired, 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? The number of doses you need can depend on your age, your health, which vaccine you get, and whether updated vaccines are recommended. Your doctor or pharmacist can tell you how to stay up to date.
Do I need to stay up to date on my COVID-19 vaccines if I've already had COVID-19? Yes. If you've had COVID-19, you can catch it again. This is especially true if the virus changes. Staying up to date on your COVID-19 vaccinations will give you extra protection.
Will I still need to wear a mask after I get vaccinated? Maybe. Even if you're up to date on your COVID-19 vaccines, you may need to wear a mask. Be sure to follow all instructions from your local health authorities and the CDC.
Why else should I stay up to date on COVID-19 vaccines? COVID-19 is unpredictable. Even if you're young and healthy, you could get very sick, have long-term health problems, or die. Without the vaccine, you are not as protected from other problems caused by getting COVID-19. This includes missing work, school, or other events. It also includes the cost of care if you get seriously ill.

The COVID-19 vaccines are one of the best ways to protect yourself and others from the virus. So stay up to date on your COVID-19 vaccines.
