Vaccine Adverse Event Reporting System (VAERS) is a national program that was developed to monitor the safety of vaccines. The program collects and evaluates information about adverse events that may be related to the administration of vaccines. VAERS is an important tool for public health officials, healthcare providers, and vaccine manufacturers to help identify potential safety concerns with vaccines. The system allows healthcare providers and vaccine manufacturers to report any adverse events associated with the administration of a vaccine, which can then be analyzed by public health experts. This helps identify any potential risks associated with certain types of vaccines or specific components in them. With VAERS, healthcare professionals can ensure that they are providing safe immunization services to their patients.
