New Study: Breakthrough Infections Generate "Super Immunity" to COVID-19

COVID-19 vaccination provides a foundation of protection that's enhanced by breakthrough infection; `the key is to get vaccinated.'

Breakthrough infections greatly enhance immune response to variants of the virus that causes COVID-19, according to a newly published study from Oregon Health & Science University.

The laboratory results, published online ahead of print in the Journal of the American Medical Association (JAMA), reveals that a breakthrough infection generates a robust immune response against the delta variant. Authors say the findings suggest the immune response is likely to be highly effective against other variants as the SARS-CoV-2 virus continues to mutate.

The study found that antibodies measured in blood samples of breakthrough cases were both more abundant and much more effective.
