Vaccines administered source data and cases, deaths, and tests source data

Data notes

Data on cases, deaths, and testing is not reported on weekends or state holidays. This data is reported on the first day following the weekend or holiday. Data on vaccines administered is reported daily.
The percentage of population vaccinated is the fully and partially vaccinated population divided by the population eligible for vaccination.
The percentage of population vaccinated will be consistently updated due to ongoing statewide vaccine record reconciliation efforts. This percentage may differ from data reported by local health jurisdictions and federal entities.
Case rate and daily avg. are based on a 7-day average with a 7-day lag.
Death rate and daily avg. are based on a 7-day average with a 21-day lag due to delays in reporting.
The population denominators used for the per 100K rates come from the California Department of Finance’s population projections for 2020.
Test positivity is based on a 7-day average with no lag. Data is provided by the California Department of Public Health.

Unvaccinated and vaccinated data

Vaccines prevent serious illness, save lives, and reduce further spread of COVID-19. As more people are vaccinated, the virus is less likely to spread, mutate, and potentially become even more dangerous. Vaccines will help put an end to the pandemic.

Unvaccinated and vaccinated cases, hospitalizations, and death source data

Chart information

A vaccinated case, hospitalization, or death is one that occurs in a person who received two doses of the Pfizer or Moderna vaccines or the Janssen vaccine at least 2 weeks before they tested positive for COVID-19.
An unvaccinated case, hospitalization, or death is one that occurs in a person who has not received a COVID-19 vaccine.
This chart uses data from people 12 and older collected over the last 120 days.
We exclude some recent, incomplete data to accurately reflect trends in the data.
The California Department of Public Health has more information about vaccinated cases, hospitalizations, and deaths.

Vaccines administered data

We’re tracking the progress of vaccinating Californians across the state.

Confirmed cases and deaths source data

Chart information

Numbers do not represent true day-over-day changes as these results include cases from prior to yesterday.
Episode date is the date the event is estimated to have taken place.
Reported date is the date the event was reported to the California Department of Public Health.
Cases includes people in state and federal prisons, US Immigration and Customs Enforcement facilities, US Marshal detention facilities, and Department of State Hospitals facilities. A negative number of reported deaths means that deaths previously attributed to COVID-19 were determined to not be associated with COVID-19.
The population denominators in these charts come from the California Department of Finance’s population projections for 2020.

Testing for COVID-19

The number of COVID-19 diagnostic test results in California reached a total of 111,530,768, an increase of — tests from the prior day total. The rate of positive tests over the last 7 days is 2.9%.

Total tests and positivity rate source data

Chart information

Testing date is the date the test was administered.
Reported date is the date the event was reported to the California Department of Public Health. Reported date data is not available for tests before May 5, 2020.
Testing date data excludes out-of-state and unknown jurisdiction tests and total numbers may not match reporting date numbers.
Positivity rate is calculated as the number of positive molecular tests divided by the total molecular tests performed. Positivity rate includes people in state and federal prisons, US Immigration and Customs Enforcement facilities, US Marshal detention facilities, and Department of State Hospitals facilities.
Positivity rate was previously reported as a 14-day average.
The population denominators in these charts come from the California Department of Finance’s population projections for 2020.
