Summary

Using detailed serial cross-sectional estimates of the age-specific distribution of SARS-CoV-2 Omicron variant-specific antibody positivity levels, we derived age-specific infection attack rates and age-specific population immunity levels and tracked the magnitude of individual-level and population-level waning immunity over time. Our findings will inform health policy makers on devising future public health and social measures and vaccination guidance in response to the ongoing COVID-19 pandemic.
