由於數據是從去年8月到今年1月收集，取自各地，數據不均勻， 所以需要調整。

回答: 可否告知疫苗效果人保護率%怎麽計算？ 由 Help14 於 2022-01-24 19:27:21

VE was calculated as ([1−odds ratio] x 100%), estimated using a test-negative design, adjusted for age, geographic region, calendar time (days since August 26, 2021), and local virus circulation (percentage of SARS-CoV-2–positive results from testing within the counties surrounding the facility on the date of the encounter) and weighted for inverse propensity to be vaccinated or unvaccinated (calculated separately for each VE estimate). Generalized boosted regression trees were used to estimate the propensity to be vaccinated based on sociodemographic characteristics, underlying medical conditions, and facility characteristics.
