Dynamics of anti-SARS-CoV-2 IgG antibody responses following breakthrough infection and the predicted protective efficacy: a longitudinal community-based population study in China

The coronavirus disease 2019 (COVID-19) pandemic has profound implications for global public health. As of March 17, 2023, there have been a staggering 774.9 million confirmed cases and 7.0 million deaths around the world [1]. Following the relaxing of the strict control strategy for COVID-19 in China in December 2022, the number of infections has grown rapidly [2]. Although the World Health Organization declared an end to the pandemic emergency on May 5, 2023 [3], localized endemic remains a possibility in the future due to the waning of vaccine-induced and infection-acquired immunity, and ongoing viral mutations [4].
