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

Data notes
  • The percentage of population vaccinated includes people who have completed their primary series and people who are vaccinated and boosted 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

COVID-19 vaccines save lives. Vaccines are safe and effective for everyone aged 6 months and older. Getting vaccinated is the most powerful tool against hospitalization, serious illness, and death.
  • COVID-19 deaths over the last four months
  • During {RATE_MONTH}, unvaccinated people were {RATE_RATIO} times more likely to die from COVID-19 than people who were vaccinated with at least a primary series.
  • Weekly deaths per million
  • Deaths per million (7-day running average)
  • Vaccinated

  • 90 days

    Unvaccinated deaths per million: {UCOUNT}
    Vaccinated deaths per million: {VCOUNT}

Unvaccinated and vaccinated cases, hospitalizations, and death source data. Data is updated on the first week of every month.

Chart information
  • A vaccinated case, hospitalization, or death is one that occurs in a person who received at least two doses of the Pfizer or Moderna vaccines or one dose of the Johnson & Johnson 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 5 and older.
  • 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 the first Friday of each month. When we publish these charts, there will be a one month 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.
  • Calculating rates by vaccination and booster status is affected by several factors that make interpretation of recent trends especially difficult. Factors including immunity from prior infection, waning protection related to the amount of time since vaccination, and differences in prevention and testing behaviors by age and vaccination status, have a growing impact on data over time. Despite these limitations, data continue to show that COVID-19 vaccination significantly reduces risk of infection and severe disease. CDPH continues to evaluate ways to present this information in a way that better accounts for these limitations.
