Sigallab conducted the study, “Omicron infection enhances neutralizing immunity against the Delta variant,” and posted a manuscript prior to its peer-reviewed publication.

The research team, led by Professor Alex Sigal, has published numerous papers on COVID-19 in well-respected journals, such as Nature and Frontiers.

Sigal posted a thread on Twitter that explains the study’s findings.
