As of data updated on October 13, 2021, Alameda County is utilizing a view of the State’s vaccination data that improves how first and second doses are matched to a person. The number and percentage of people fully vaccinated, therefore, increased starting on October 13 as a result of the number of partially vaccinated decreasing. The implementation of this change is retroactive, so data in the past will reflect this update, too.
This dashboard relies on multiple data systems at the state and local levels, and experiences occasional fluctuations as those systems coordinate and update data. Local updates made in the State’s electronic contact tracing system CalConnect are communicated to the State’s disease reporting system, CalREDIE, which populates the data dashboard. Death data may be corrected from time to time as information about the cause of death or the County of residence of the deceased person are finalized.
Weekly routine maintenance of CalREDIE by CDPH may impact local COVID case counts.
Notes and disclaimers: We have masked the UC Berkeley tract (06001422600) and zip (94720) and several nearby tracts and zips for vaccination. Any tract or zip where college and graduate students make up more than 40% of the population according to the American Community Survey 2015-2019 has been masked, including the Mills College zip (94613). The vaccination data from the state shows relatively low vaccination rates in these areas due to (1) a lack of documentation of students in the CAIR system; or (2) inconsistent population estimates for these areas because many students are not living in Berkeley or at Mills College this year; or (3) students providing a different (permanent) address when receiving their vaccine. More information on vaccination rates of UC Berkeley students and staff can be found at https://coronavirus.berkeley.edu/dashboard/immunization/.
