Why Get the Vaccine?

Avoid Contracting the Virus

All COVID-19 vaccines currently available in the United States have been shown to be highly effective at preventing COVID-19. Learn more about the different COVID-19 vaccines.
All COVID-19 vaccines that are in development are being carefully evaluated in clinical trials and will be authorized or approved only if they make it substantially less likely you’ll get COVID-19. Learn more about how federal partners are ensuring COVID-19 vaccines work.
Based on what we know about vaccines for other diseases and early data from clinical trials, experts believe that getting a COVID-19 vaccine may also help keep you from getting seriously ill even if you do get COVID-19.
Getting vaccinated yourself may also protect people around you, particularly people at increased risk for severe illness from COVID-19.
Experts continue to conduct more studies about the effect of COVID-19 vaccination on severity of illness from COVID-19, as well as its ability to keep people from spreading the virus that causes COVID-19.

Safely Protect Yours and Other's Immunity

COVID-19 can have serious, life-threatening complications, and there is no way to know how COVID-19 will affect you. And if you get sick, you could spread the disease to friends, family, and others around you.
Clinical trials of all vaccines must first show they are safe and effective before any vaccine can be authorized or approved for use, including COVID-19 vaccines. The known and potential benefits of a COVID-19 vaccine must outweigh the known and potential risks of the vaccine for use under what is known as an Emergency Use Authorization (EUA). Watch a video on what an EUA is.
Getting COVID-19 may offer some natural protection, known as immunity. Current evidence suggests that reinfection with the virus that causes COVID-19 is uncommon in the 90 days after initial infection. However, experts don’t know for sure how long this protection lasts, and the risk of severe illness and death from COVID-19 far outweighs any benefits of natural immunity. COVID-19 vaccination will help protect you by creating an antibody (immune system) response without having to experience sickness.
Both natural immunity and immunity produced by a vaccine are important parts of COVID-19 disease that experts are trying to learn more about, and CDC will keep the public informed as new evidence becomes available.

Help Stop the Pandemic

Wearing masks and social distancing help reduce your chance of being exposed to the virus or spreading it to others, but these measures are not enough. Vaccines will work with your immune system so it will be ready to fight the virus if you are exposed.
The combination of getting vaccinated and following CDC’s recommendations to protect yourself and others will offer the best protection from COVID-19.
Stopping a pandemic requires using all the tools we have available. As experts learn more about how COVID-19 vaccination may help reduce spread of the disease in communities, CDC will continue to update the recommendations to protect communities using the latest science.
