Key facts about COVID-19 vaccines

Studies have shown that COVID-19 vaccines are safe to get and highly effective at preventing you from getting COVID-19. Even if you do get COVID-19, the vaccine prevents you from getting seriously ill. The more people that get vaccinated, the faster we can get back to normal life.

They’re safe

Rigorous clinical trials must show that vaccines are safe and effective before they’re authorized for public use. Millions of people have received COVID-19 vaccines, which have undergone the most intensive safety monitoring in US history.

They’re effective

All approved vaccines are proven to be highly effective at preventing COVID-19. Based on what we know so far, experts believe that all the approved vaccines will nearly 100% prevent serious illness and death. They may also help protect family, friends, and those around you.

They’re free

COVID-19 vaccines will be free for all Americans under the CARES act. The US government has already ordered and paid for hundreds of millions of COVID-19 vaccine doses using US tax dollars to ensure that everyone who wants one can get one.

Top vaccine myths

When deciding to get vaccinated, it’s important to separate fact from fiction.

The vaccines will not make you sick with COVID-19.

    What is an EAU?

    Normally, the U.S. Food and Drug Administration (FDA) puts products through rigorous testing and collects evidence to establish its efficacy and safety. During declared emergencies such as the COVID-19 pandemic, the FDA weighs the potential risks and benefits of approving a product quickly. An EAU (emergency use authorization) is issued only after the FDA, in consultation with a coalition of government health entities, determines that the benefits outweigh the risks.
