Vaccine safety

Any medical event occurring after immunisation can be classified as an adverse event following immunisation (AEFI) whether the event has any causal relationship to getting the immunisation or not. 
Throughout the development of a new vaccine, from discovery to marketing and beyond, the safety of each candidate vaccine is carefully assessed. At any stage, development is discontinued if the safety risk outweighs the benefit.
