Covid-19 Safety and MonitoringApril 2022

Covid Vaccine Safety and Monitoring Information

  • COVID-19 vaccines were developed using principles that have existed for decades.
  • COVID-19 vaccines are safer than contracting the COVID-19 virus.
  • COVID 19-vaccines are effective at preventing severe illness from COVID-19 and reducing the spread of the virus.

Millions of people in the US have been given COVID-19 vaccines under the most intense safety monitoring in the country’s history. The CDC recommends getting a COVID-19 vaccine as soon possible.

To ensure the safety of COVID-19 vaccines, the CDC has broadened the US’ ability to monitor vaccine safety. The CDC has new ways of collecting additional information about the safety of COVID-19 vaccines. These web-based platforms give CDC scientists real-time information about the dependability of COVID-19 vaccines.

With increased monitoring, vaccine safety experts can oversee and detect issues that may not have been observed during the clinical trials. If any vaccine safety issues (adverse events) are reported, CDC scientists can quickly determine if there is a safety concern with a particular vaccine. Some of the tools that CDC uses to keep close tabs on the safety of COVID-19 vaccines include:

  • V-safe provides quick and confidential health check-ins via text messages and web surveys. You can quickly and easily share with CDC how you feel after getting a COVID-19 vaccine.
  • Vaccine Adverse Event Reporting System (VAERS) is the national system that collects reports of adverse events that happen after COVID-19 vaccination.
