Ensuring COVID-19 Vaccine Safety in the US
To make sure that COVID-19 vaccines are safe, CDC expanded and strengthened the country’s ability to monitor vaccine safety. CDC created new web-based platforms to gather more information about the safety of COVID-19 vaccines. These 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:
