Additionally, a study from July 2022 looked at vaccinated people and their antibody titers, which measures the amount of antibodies in their blood. Experts will continue to monitor this and update guidance as needed. But making them is a process that takes time. Prevalence of antibody positivity to SARS-CoV-2 following the first peak of infection in England: Serial cross-sectional studies of 365,000 adults. National Institutes of Health.
