Updated data on San Francisco residents that have received a COVID-19 vaccine booster dose

The San Francisco Department of Public Health (SFDPH) is working to provide vaccine booster doses to all SF residents 18 and over.

While data show that COVID-19 vaccines continue to protect against severe illness, over time the level of antibodies produced by the vaccine decrease. This waning immunity can leave vulnerable groups susceptible to severe illness and hospitalization as a result of a breakthrough infection. A breakthrough infection occurs when someone has received either both doses of a two-dose vaccine or one dose of a one-dose vaccine and is infected with COVID-19. The SFDPH, in alignment with state guidance, is recommending that all adults get a vaccine booster dose to reduce COVID-19 transmission and protect against severe illness and hospitalization. Older adults and those with underlying health conditions are particularly encouraged to prioritize their booster.

Who is eligible to receive a booster dose?

Everyone should get the booster dose if they are 18 years of age and older and have completed their primary vaccine series six months ago for the mRNA vaccines (Pfizer and Moderna) or received the 1-dose vaccine (Johnson & Johnson) at least two months ago.

Data on booster doses will be updated on a weekly basis to provide information and context to the COVID-19 pandemic in San Francisco.

Data highlights for San Francisco residents that have received a COVID-19 vaccine booster dose

(Data through November 29th, 2021)

Booster recipients over time

Since booster doses were first authorized at the end of September 2021, residents have increasingly chosen to receive an additional vaccine dose to boost their immunity to COVID-19. To date, approximately 201,871 residents have received a COVID-19 booster dose. In the last week (Nov 22 - Nov 28), approximately 3,751 residents on average have received a booster dose each day.

In August, SFDPH authorized providers to offer an additional COVID-19 vaccine dose to individuals who received a Johnson & Johnson vaccine to help protect against severe COVID-19 infection and hospitalization. SFDPH considers doses administered after the initial Johnson & Johnson dose to also be boosters.

Number of residents that received a booster dose by date

Booster recipients by age

Individuals ages 65 and older are at increased risk of hospitalization following a breakthrough infection. As the effectiveness of the vaccines decrease over time, older adults are encouraged to get a booster dose to increase their protection against COVID-19. All adults, ages 18 and older are encouraged to receive a COVID-19 booster dose if they received their second dose of an mRNA vaccine series at least six months ago or received their Johnson & Johnson dose at least two months ago.

Percent of residents with a booster dose by age group

With an estimated 123,898 residents 65 and older in San Francisco who are eligible to receive a COVID-19 booster, 53% of eligible San Franciscans ages 65 and older have received a booster dose as of November 29th. Compared to 37% of eligible 50-64 year olds and 26% of 18-49 year olds, residents 65 year of age and older have received more COVID-19 booster doses. This is expected as individuals 65 years of age and older are a priority population to receive the booster dose regardless of health status, occupation, or living status.

Booster recipients by race/ethnicity

Among eligible residents 65 years of age and older, about 46% of American Indian or Alaska Native residents, 54% of Asian residents, 47% of Black or African American residents, 51% of Hispanic or Latino/a residents, 41% of Native Hawaiian or Other Pacific Islander residents, and 62% of white residents have received a booster dose.

Percent of residents 65 and older with a booster dose by race/ethnicity

Throughout the COVID-19 pandemic, SFDPH has focused on racial and social equity in administering vaccines. While SFDPH continues to focus on ensuring access to the primary vaccine series, we’re committed to making sure that booster vaccines are also available to all residents.
