SF Department of Public Health offering supplemental vaccines to some who received J&J shot


In some circumstances, the San Francisco Department of Public Health will offer extra COVID-19 vaccines to those who received Johnson-Johnson single-dose.

The shot is available to people who have received the Johnson & Johnson vaccine, who have, in many cases, consulted with their doctor and who want to receive an extra dose of Pfizer or Moderna vaccine.

The Johnson & Johnson vaccine is 66.3% effective in preventing the contraction of COVID-19, the Centers for Disease Control and Prevention said. Pfizer and Moderna two-dose vaccines are approximately 95% effective in preventing COVID-19 contractions.


“This move does not represent a change in policy for SFDPH,” the agency said in a statement. “We continue to align with the Centers for Disease Control and Prevention advice and do not recommend a booster shot at this time.”

SFDPH said it will “continue to review any new data and adjust our advice, if necessary.”

Vaccines will be available at Zuckerberg General Hospital San Francisco this weekend, ABC7 report.

Dr. Lisa Winston, chief of staff at Zuckerberg General Hospital in San Francisco, where the program is being undertaken, said ABC7 that he is not aware of any similar program elsewhere in the nation.

“Potential benefits, no downsides,” said Dr. Chris Colwell, chief of emergency medicine at Zuckerberg San Francisco General. “For me, as we look to the future of this virus and now we’re facing a fourth wave, it makes sense.”

The extra vaccine is not a booster shot because it is not specifically used to combat variants, he added.

As of Monday, 76% of San Francisco residents received at least one shot of the vaccine, according to given the city.
