Neutralization Profile after Recovery from SARS-CoV-2 Omicron Infection

Convalescent Antibodies after Omicron Infection Although considerable data show cross-reactivity among antibodies generated by infection with the various SARS-CoV-2 variants of interest, a group of persons who were not previously vaccinated but were recovering from infection with the omicron BA.1 variant were found to have antibodies that were largely ineffective in neutralizing the other viral strains.

Automated summary

Although some antibodies generated in persons recovering from infection with the omicron variant show cross-reactivity, a group of unvaccinated individuals were found to have largely ineffective antibodies against other viral strains.
