People getting infected after vaccination show stronger immunity against Covid-19: Study

The findings suggest that the immune response in vaccinated people is likely to be highly effective against other variants as the SARS-CoV-2 virus continues to mutate.

Washington: People who are infected after getting vaccinated develop a greatly enhanced immune response to variants of the SARS-CoV-2 virus that causes COVID-19, according to a lab study. The research, published in the Journal of the American Medical Association (JAMA), shows that a breakthrough infection generates a robust immune response against the Delta variant.

The findings suggest that the immune response in such people is likely to be highly effective against other variants as the SARS-CoV-2 virus continues to mutate. "You can't get a better immune response than this. These vaccines are very effective against severe disease," said study senior author Fikadu Tafesse, an assistant professor at Oregon Health & Science University (OHSU) in the US.

"Our study suggests that individuals who are vaccinated and then exposed to a breakthrough infection have super immunity," Tafesse said.
