Vaccines are a miraculous invention of mankind. However, there are always two sides of a coin. Vaccines also may cause adverse reactions; sometimes in a few minutes and rarely, years later. Different reactions/adverse events/AEFIs reported for vaccines indeed should be submitted to concerned regulatory authorities. Some regulatory authorities have defined guidance and formats for reporting vaccine-related adverse events, other than medicine/drug reporting formats while few other regulatory authorities are in process of defining such reports and monitoring process in vaccine safety.
World Health Organization (WHO) is relentlessly working for vaccine safety and monitoring. The global vaccine action plan, immunization surveillance, assessment, and monitoring etc. and other plan of action are available for reference on their website. European medicinal agency (EMA) is also working on this initiative by establishing Vaccine Adverse Event Surveillance & Communication (VAESCO) for recording information related to AEFIs etc. Likewise, US FDA has a VAERS (Vaccine adverse event reporting system) form in order to report vaccine adverse events.
