COVID-19 Booster vaccinations among county residents by age group

The dataset provides number of county residents who are booster vaccinated by age group. Number of people vaccinated (completed primary series) is the number of county residents who either received a vaccine requiring a single dose (Janssen/Johnson & Johnson) or received the second dose of a vaccine requiring two doses (Pfizer or Moderna).

Counties are experiencing temporary fluctuations in vaccination data received from the State of California due to a data reconciliation process involving integration of vaccination data systems by the State. The data reconciliation process and associated fluctuations in county vaccination are expected to be resolved by May 2022

该数据集提供了按年龄段划分的接种加强针的县级居民人数。接种人数（完成初级系列）指的是既接种了单剂疫苗（杨森/强生）的居民，又接种了需要两剂疫苗的第二剂的居民（辉瑞或莫德纳）。数据来源：加利福尼亚免疫登记处。此表格于周一至周五更新，节假日不予更新。

由于加州正在整合疫苗接种数据系统，涉及数据核对过程，导致从加州州政府接收的疫苗接种数据出现暂时波动。预计到2022年5月，数据核对过程和县级疫苗接种数据的波动问题将得到解决。
