Connect to the websites and resources healthcare professionals need to address side effects of vaccination or health issues that arise after vaccination, whether or not they are believed to be related to vaccination.
Managing Vaccine Adverse Events
It is important to appropriately address and report all vaccine adverse events. Some very rare adverse events develop days after vaccination. They are described in vaccine-specific resources. Some adverse events, such as an allergic reaction, occur within minutes of vaccination and must be addressed immediately.
These resources address immediate adverse events, such as allergic reactions or fainting.

Reporting Vaccine Adverse Events
Every vaccination provider has a responsibility to report health problems (adverse events) that occur after vaccination. Reporting is important following a vaccine administration error, such as administering an injection in a location that results in a shoulder injury, or administering the wrong product. The Vaccine Adverse Event Reporting System (VAERS) is a nationwide system for monitoring adverse events following vaccination. VAERS is operated jointly by the FDA and the CDC. This system accepts all reports from any person. A report does not mean that the vaccine caused the reaction. The system is important to detect patterns and identify reports for further study.
