The state says it is administering the correct dose at the Oakland Coliseum despite claims


The state of California said Wednesday that it cannot substantiate claims made by a KTVU report that a vaccine dose issue at the Oakland Coliseum mass vaccination site on Monday resulted in thousands of people receiving doses of the Pfizer vaccine. smaller than recommended.

“We are not aware of any cases of even a single person being under-vaccinated at the Oakland Coliseum site,” Brian Ferguson, a spokesman for the Cal OES that runs the site, wrote in an email statement.

Anonymous sources in the KTVU report said that some vaccine recipients received less than the optimal 0.3 ml dose because the syringe plunger did not reach the bottom of the plastic cylinder. As a result, people were injected with less than 0.3 ml of vaccine.


A source told KTVU that approximately 4,300 people received less than the optimal dose. There are about 6,000 people vaccinated a day at the site.

Doses of less than 0.3 ml were administered before 2 p.m. Monday, according to KTVU sources, which were identified as EMT.

The vaccines administered were manufactured by Pfizer, which requires two doses administered three weeks apart. The syringes used to administer them are provided by the federal government.

“The state and federal partners providing vaccines on this site have been working closely with the California Department of Public Health, the US Health and Human Services, the Centers for Disease Control and Prevention, as well as with vaccine manufacturer Pfizer to ensure the highest levels of medical care – and they are met on this site, “said Ferguson.

Dr. John Swartzberg, a professor of infectious diseases at UC Berkeley, said that if there were people at Oakland Coliseum who got a smaller dose, “as a doctor and knowing how vaccines work, that doesn’t alarm me and I think my I would be protected, but I want to hear that from people who know more than I do. I want the scientists at the FDA and Pfizer to advise what we should do, since they will know what we should do. “

Swartzberg said that if you had a patient get a smaller dose, I wouldn’t recommend that they get an extra vaccine or a larger booster shot. I’d check in with the experts, thinking maybe a third shot would be needed in three or four months.

Pfizer declined to comment for this story. The California Department of Public Health and the US Health and Human Services were not immediately available for comment.
