wrote in a commentary published earlier this summer.A study published last month by researchers at Rockefeller University found the combination of prior infection and vaccination broadened the strength of people’s immunity against a changing virus.
The antibodies in these individuals were found to neutralize six variants of concern that were tested, including the delta strain. "One could reasonably predict that these people will be quite well protected against most — and perhaps all of — the SARS-CoV-2 variants that we are likely to see in the foreseeable future," Paul Bieniasz, a virologist at Rockefeller University who helped lead several of the studies, told NPR.
