Ensuring COVID-19 Vaccine Safety in the US
Vaccine Safety and Monitoring
- COVID-19 vaccines were developed using science that has been around for decades.
- COVID-19 vaccines are safe—much safer than getting COVID-19.
- COVID 19-vaccines are effective at preventing severe illness from COVID-19 and limiting the spread of the virus that causes it.
Millions of people in the United States have received COVID-19 vaccines under the most intense safety monitoring in U.S. history. CDC recommends you get a COVID-19 vaccine as soon as you can.
To make sure that COVID-19 vaccines are safe, CDC expanded and strengthened the country’s ability to monitor vaccine safety. CDC created new ways to gather more information about the safety of COVID-19 vaccines. These web-based platforms give CDC scientists information about the safety of COVID-19 vaccines in real time.
As a result, vaccine safety experts can monitor and detect issues that may not have been seen during the COVID-19 vaccine clinical trials. If any vaccine safety issues—also called adverse events— are reported, CDC scientists can quickly study them and determine if there is a safety concern with a particular vaccine. Here are some of the tools that CDC uses to keep close tabs on the safety of COVID-19 vaccines:
Use your smartphone to tell CDC how you’re feeling after your COVID-19 vaccination and personalized health check-ins to make sure you’re doing well
