| Abstract | We conducted two prospective cohort studies (June 2022–March 2023 and Nov 2023–Jan 2024) of 1,899 and 445 residents and other individuals who are affiliated with institutions in the city of Bizen in Japan's Okayama prefecture (population 32,320 as of 2020). We measured the subjects' titers of antibodies against SARS-CoV-2, evaluated changes in their antibody titers, and assessed the associations of the titers with the subjects' vaccination status, infection, and COVID-19 status/severity. This report summarizes the two studies' findings. These prospective studies based on a wide age range in a general population provide information that can be used to determine the appropriate timing of vaccination during a pandemic.
