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
