Mean geometric titer

WebIn a population seronegative before vaccination, the post-vaccination geometric mean titre (post-GMT) is a meaningful immunological parameter adequately expressing antibody response after vaccination. The related protection rate (PR) is a good surrogate parameter for protection provided by a given vaccine, thus relevant to public health. WebAug 1, 2024 · The HI antibody responses were described as geometric mean titers (GMT) and their 95% confidence intervals (CI) were calculated. The chi square test was used to compare categorical variables.
