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

Data notes
  • 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.
  • All daily averages are 7-day averages.
  • Vaccines administered have a 7-day lag.
  • Cases have an 8-day lag.
  • Deaths have a 22-day lag due to delays in reporting.
  • Tests have a 1-day lag.
  • Case and death data from Los Angeles and San Diego counties have an additional 1-day lag.
  • Testing data from Los Angeles county have a 1-day lag.
  • 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.
  • COVID-19 cases over the last four months
  • From {BEGIN_IMPACT_DATE} to {END_IMPACT_DATE}, unvaccinated people were {RATE_RATIO} times more likely to get COVID-19 than people who received their booster dose.
  • Weekly cases per 100K
  • Cases per 100K (7-day running average)
  • Vaccinated and boosted
  • Vaccinated but not boosted
  • Unvaccinated
  • Data pending

    Vaccinated cases per 100K: {VCOUNT}
    Boosted cases per 100K: {BCOUNT}

Unvaccinated and vaccinated cases, hospitalizations, and death source data. Data is updated on Fridays.

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 Johnson & Johnson vaccine at least 2 weeks before they tested positive for COVID-19.
  • A boosted case, hospitalization, or death is one that occurs in a person who received an additional or booster dose on or after August 13, 2021, 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.
  • There is a data lag for these charts. Matching of COVID-19 cases (including hospitalizations and deaths) and vaccination status happens weekly, contributing to some lag. This compounds with natural reporting lags for cases and hospitalizations, which is larger for deaths.
  • We update these charts on Wednesdays. When we publish these charts:
    • The cases and hospitalizations charts have a 17-day lag.
    • The deaths chart has a 24-day lag.
  • 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.

Confirmed cases and deaths source data. Data is updated on Tuesdays and Fridays.

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. It is the most accurate source of data over time.
  • 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.
  • Data from Los Angeles and San Diego counties have a 1-day lag.
  • A negative number of cases is a result of data quality work, including removing duplicate cases.
  • 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 165,553,649, an increase of 1,082,203 tests from the prior day total. The rate of positive tests over the last 7 days is 5.0%.

Cases and deaths by ethnicity, gender, and age
