The team found that people who had received three-vaccine doses, those vaccinated after recovering from COVID-19, and those with a breakthrough infection had almost comparable neutralising antibody responses, in terms of magnitude and breadth.

Breakthrough COVID-19 Infections Generate Strong Antibody Response: Study

People vaccinated three times or immunised after an earlier COVID-19 infection have comparable neutralising antibody response to those with a breakthrough infection, according to a study.

A breakthrough infection is a case of illness in which a fully vaccinated individual becomes infected.
