Breakthrough infection

Breakthrough infection is an illness suffered by an individual who has previously been vaccinated for the same illness. Such illnesses occur when the vaccines fail to provide the immunity against the pathogen they were designed to target. According to experts, COVID-19 variants may be behind the breakthrough infections seen in India, which has recorded 2-4 breakthrough infections per 10,000. However, in majority of cases, the breakthrough infections did not lead to hospitalisation.
