Data show that COVID-19 vaccines continue to protect against severe illness. Still, over time the level of antibodies produced by the vaccine decrease. As a result, vulnerable groups may be at risk of severe illness or hospitalization if they get a breakthrough infection. A breakthrough infection is when someone has received both doses of a two-dose vaccine or one dose of a one-dose vaccine and then afterwards is infected with COVID-19.

Learn about who is recommended to get a booster of the COVID-19 vaccine at this link. A vaccine booster will help to reduce the spread of COVID-19 and protect against severe illness and hospitalization. Older adults and those with underlying health conditions are especially encouraged to get a booster dose.

Residents with a vaccine booster

The chart below shows San Francisco residents who have received a booster dose of the COVID-19 vaccine. It includes all residents who received a booster from any provider, even if they got a booster somewhere else in California.

People who do not live in San Francisco are not included, even if they got a booster in San Francisco.

Data comes from the California Immunization Registry (CAIR2). CAIR2 is run by the California Department of Public Health.

The San Francisco Department of Public Health (SFDPH) identifies booster recipients in CAIR2 as follows:

  • Residents who meet current age-group recommendations; and
  • Residents who have received an additional dose after completing their primary vaccine series.
    • For residents who received a two-dose vaccine for their primary series (Pfizer or Moderna), their third dose is identified as a booster dose in the data.
    • For residents who received a one-dose vaccine for their primary series (Johnson & Johnson), their second dose is identified as a booster dose in the data.

“Total booster recipients” shows the total number of unique San Francisco residents who have received a booster dose of the vaccine.

“Daily new booster recipients” shows the 7-day rolling average number of residents getting a booster dose of the vaccine. The 7-day rolling average is the average number of residents that got a booster dose on a particular day and the previous 6 days. This rolling average helps smooth out day-to-day fluctuations.

The Centers for Disease Control and Prevention (CDC) recommends that immunocompromised individuals receive a third COVID-19 vaccine dose as part of their primary series. These individuals may be eligible to receive a fourth vaccine dose as a booster. It is not possible to identify the health status of vaccinated residents in the CAIR2 data. Therefore, the data on residents with a booster dose includes some individuals who got a third vaccine dose as part of their primary series.

Residents with a vaccine booster administered by SFDPH

The chart below shows San Francisco residents who have received a booster dose of the COVID-19 vaccine from the San Francisco Department of Public Health (SFDPH).

People who do not live in San Francisco are not included, even if they got a booster in San Francisco from SFDPH.

Residents with a vaccine booster by race or ethnicity

The chart below shows the estimated percent of residents by race and ethnicity who have received a COVID-19 vaccine booster out of all residents who have completed their primary COVID-19 vaccine series and are eligible or recommended to receive a booster. A primary vaccine series is complete after an individual has received both doses of a two-dose vaccine or one dose of a one-dose vaccine.

As more residents complete their primary vaccine series, the population that can receive boosters will grow. As a result, it is possible that the percent of vaccinated residents who have received a booster dose may sometimes decrease even while the total number receiving booster doses increases.

Data comes from the California Immunization Registry (CAIR2). CAIR2 is run by the California Department of Public Health.

San Francisco residents who have received a booster dose from a California provider reporting to CAIR2 are included in these data. All booster recipients living in San Francisco are included in these data. This includes residents who got their booster outside San Francisco. Boosters administered in San Francisco to non-city residents are not included.

The San Francisco Department of Public Health (SFDPH) identifies booster recipients in CAIR2 as follows:

  • Residents who meet current age-group recommendations; and

    • For residents who received a one-dose vaccine for their primary series (Johnson & Johnson), their second dose is identified as a booster in the data.

The population of residents with a complete vaccine series is different from the estimated San Francisco resident population. The estimated resident population is used to calculate the percent of residents vaccinated with at least one dose or a completed series in these dashboards. The population of residents with a complete vaccine series is based on vaccine records for San Francisco residents and not population estimates from the American Community Survey.

The Centers for Disease Control and Prevention (CDC) recommends that immunocompromised individuals receive a third COVID-19 vaccine as part of their primary series. These individuals may be eligible to receive a fourth vaccine dose as a booster. It is not possible to identify the health status of vaccinated residents in the CAIR2 data.

Residents with a vaccine booster by age

The chart below shows the estimated percent of residents by age who have received a COVID-19 vaccine booster out of all residents who have completed their primary COVID-19 vaccine series and are eligible or recommended to receive a booster. A primary vaccine series is complete after an individual has received both doses of a two-dose vaccine or one dose of a one-dose vaccine.

    • For residents who received a one-dose vaccine for their primary series (Johnson & Johnson), their second dose is identified as a booster in the data.

To calculate the percent of residents with a booster dose by age, we divide the number of residents who have received a booster dose by the number of residents who have completed their primary vaccine series. Because some people aged (i.e., had a birthday) between their primary series dose(s) and their booster dose, each resident’s age is calculated twice. Their first calculated age is based on the date they completed their primary vaccine series. Their second calculated age is based on the date they received a booster dose. Some people aged into a new age group for their booster dose. For these individuals, they will appear in different age groups for the numerator and denominator. For example, if someone was 64 years old when they completed a primary series and were 65 when they got a booster, they would count in the 50-64 age group for their primary vaccine series (denominator) and the 65+ age group for boosters (numerator). As a result, the percent of vaccinated residents who received a booster is only an estimate and so percentages will not be reported above 90%.

The population of residents with a complete vaccine series is different from the estimated San Francisco resident population. The estimated resident population is used to calculate the percent of residents vaccinated with at least one dose or a completed series in these dashboards. The population of residents with a complete vaccine series is based on vaccine records for San Francisco residents and not population estimates from the American Community Survey.

Residents with a vaccine booster by neighborhood

The chart below shows the estimated percent of residents by neighborhood who have received a COVID-19 vaccine booster out of all residents who have completed their primary COVID-19 vaccine series in that neighborhood and are eligible or recommended to receive a booster. A primary vaccine series is complete after an individual has received both doses of a two-dose vaccine or one dose of a one-dose vaccine.

This map includes all booster doses administered by any provider to any San Francisco resident.

Neighborhoods with a higher rate of residents with a booster dose are darker blue.

Neighborhoods with a lower rate of residents with a booster dose are light yellow.

As more residents complete their primary vaccine series, the population that can receive boosters will grow. As a result, it is possible that the percent of vaccinated residents who have received a booster dose may sometimes decrease even while the total number receiving booster doses increases.

Neighborhood results in the map do not include people that did not report a valid street address. So, the total residents with a booster in this map may be less than the total residents with a booster. That number includes residents who identified San Francisco as their home county, even if they did not have a valid street address.
