ABOUT

  • What is AEFI – Any untoward medical occurrence which follows immunization and which does not necessarily have a causal relationship with the usage of the vaccine.
  • Effective vaccines (i.e. vaccines inducing protective immunity) may produce some undesirable side effects which are mostly mild and clear up quickly.
  • The majority of events thought to be related to the administration of a vaccine are actually not due to the vaccine itself – many are simply coincidental events, others (particularly in developing countries) are due to human, or programme, error.
  • It is not possible to predict every individual who might have a mild or serious reaction to a vaccine, although there are a few contraindications to some vaccines.
  • By following contraindications the risk of serious adverse effects can be minimized.
  • If not rapidly and effectively dealt with, can undermine confidence in a vaccine and ultimately have dramatic consequences for immunization coverage and disease incidence.
  • Alternatively, vaccine-associated adverse events may affect healthy individuals and should be promptly identified to allow additional research and appropriate action to take place.
  • In order to respond promptly, efficiently, and with scientific rigour to vaccine safety issues, WHO has established a Global Advisory Committee on Vaccine Safety.
