Such cases are referred to as AEFI or ‘Adverse Event Following Immunisation’. It is defined as: Any untoward medical occurrence which follows immunisation and which does not necessarily have a causal relationship with the usage of the vaccine. It can be any unfavourable or unintended sign, abnormal laboratory finding, symptom or disease
In a press note, the health ministry claimed that media reports talking about AEFIs following vaccination were based on “incomplete and limited understanding of the matter at hand”.
“The number of deaths reported following COVID-19 vaccination in the country is only 0.0002% of 23.5 crore doses administered which is within the expected death rates in a population,” the press note added.
