According to a study, people who were vaccinated three times or immunised after an earlier COVID-19 infection had similar neutralising antibody responses to those who had a breakthrough infection.

A breakthrough infection occurs when a person who has been properly vaccinated becomes infected.

The study, which was published in the journal Cell, looked at the strength, persistence, and breadth of the neutralising antibody response induced by breakthrough infections in SARS-CoV2 vaccine recipients.

The Delta and Omicron coronavirus variants show improved transmissibility and immune evasion compared to the original virus, according to researchers from the University of Washington in the United States.

These characteristics, and the waning of immunity from vaccines, have led to breakthrough infectionsin vaccinated individuals, they said.
