About the study In the present report, researchers evaluated humoral immunity levels against SARS-CoV-2 among Finnish adults between 2020 and 2022, emphasizing immune protection against the SARS-CoV-2 Omicron variant of concern . COVID-19 vaccination data were retrieved from the national vaccination register and PCR results from the national infectious diseases register of Finland. In addition, data were obtained on at-home SARS-CoV-2 antigen tests for individuals participating in 2022. The level of humoral protection against SARS-CoV-2 was evaluated by integrating anti-S IgG and anti-N IgG titers with SARS-CoV-2 vaccination data.

Anti-N IgG rates were 1.0 years of PCR-confirmed SARS-CoV-2 infections, SARS-CoV-2 anti-N IgG titers were observed among 291 , 146 , and 26 samples, respectively.
