COVID-19 Booster Vaccination among County Residents by Census Tract

Percentage of county residents who are boosted with COVID-19 vaccines by census tract of residence. Source: California Immunization Registry. Note: Doses administered are categorized as a booster dose if the dose is a third dose administered six or more months after a second dose of Pfizer or Moderna or if the dose is a second dose administered two or more months after a dose of Janssen/Johnson & Johnson. Percent of residents who are boosted with COVID-19 vaccines and population age 12 years and older is based in part on estimates of the number of people residing in the census tract from a population-based survey sample, which is subject to error. As a result, percent vaccinated may be over- or under-estimated. For this reason, the displayed percent of residents vaccinated in a census tract is capped at 95%.

居住于各普查区县居民接种COVID-19疫苗加强针的比例。数据来源：加利福尼亚免疫登记处。注：若剂量为在第二剂辉瑞或莫德纳疫苗后六个月或更长时间内施行的第三剂，或为在杨森/强生疫苗剂量后两个月或更长时间内施行的第二剂，则将该剂量归类为加强剂。12岁及以上居民接种COVID-19疫苗的比例及人口数基于基于人口调查样本中居住在普查区的人数估计，该估计存在误差。因此，接种率可能被高估或低估。鉴于此，普查区接种疫苗的百分比上限为95%。各普查区县居民接种COVID-19疫苗的情况每周二更新。本表最后更新时间为2023年1月24日。
