Facts about the COVID-19 vaccine

COVID-19 vaccination is an important tool to help stop the pandemic. 

COVID-19 vaccines will protect you from getting sick or severely ill with COVID-19 and may also help protect people around you.

COVID-19 vaccines are safe and effective. The Food & Drug Administration (FDA) requires rigorous safety testing before it will approve any vaccine. The COVID-19 vaccines from Pfizer, Moderna and Johnson & Johnson were tested in tens of thousands of study participants and generated enough data to convince the FDA that the vaccines were safe and effective. Vaccine Testing and the Approval Process.

Vaccination gives us hope that the pandemic will end, but in the meantime, we need to continue safety measures to keep the virus from spreading: Wear a mask, physically distance from others, wash your hands, avoid gatherings, and stay home when you’re sick.

Immunity is not immediate. Full immunity from the vaccination will not take place until 14 days after the final dose of whichevr vaccine your've received.

You will stll need to abide by current safety measures. You will still need to continue to wear a mask, wash your hand frequently and physically distance even after you are fully vaccinated. Things can't go back to normal until enough people are vaccinated. If we all work together, we'll get to that point faster and save lives in the process.

COVID-19 vaccines and new variants of the virus

New variants of the virus that causes COVID-19 illness have emerged. Current data suggest that COVID-19 vaccines used in the United States should work against these variants. For this reason, COVID-19 vaccines are an essential tool to protect people against COVID-19, including against new variants. The Centers for Disease Control and Prevention (CDC) recommends getting vaccinated as soon as vaccine is available to you.

Evidence is limited on how the new COVID-19 variants will affect how COVID-19 vaccines work in real-world conditions. CDC has systems in place to monitor how common these variants are and to look for the emergence of new variants. CDC will continue to monitor variants to see if they have any impact on how COVID-19 vaccines work in real-world conditions.
