Vaccine Safety Questions and Answers.

The article provides information on the reporting requirements for adverse events following vaccine administration, as mandated by the National Childhood Vaccine Injury Act (NCVIA). Healthcare providers are required to report specific events, and vaccine manufacturers must also report adverse experiences to the FDA. The article emphasizes the safety and effectiveness of vaccines and highlights the success of immunization programs in reducing vaccine-preventable diseases. The CDC supports state governments in enacting and enforcing immunization laws, and exemptions for vaccination requirements vary among states. Vaccinations have been effective in reducing the incidence of diseases, and high vaccination rates contribute to "herd immunity." Adverse event information can be obtained through a Freedom of Information Act (FOIA) request with the FDA, and vaccine expiration dates can be extended based on data submitted to the FDA by the manufacturer.
