An estimated 4,300 individuals in California received a smaller coronavirus vaccine than they should have because of a problem with injecting.
According to KTVU, the Oakland Coliseum site received orange-cap syringes that left a third of the vaccine on the bottom of the plastic container. The problem was finally discovered on Monday, but individuals vaccinated before that point reportedly received only 0.2ml of the Pfizer vaccine instead of the optimal 0.3ml.
The California Office of Emergency Services, which helps run the site with the Federal Emergency Management Agency, said high-level meetings Tuesday after whistleblowers warned of the matter.
Cal OES spokesperson Brian Ferguson reportedly said he did not think anyone was formally underdosed and there was no need to contact the individuals who received the lower vaccine amount.
On Wednesday, he said authorities were told the dosage was within medical guidelines and protocols.
Dr. Peter Chin-Hong, an infectious disease expert, reportedly said the patients were “likely protected” and could make up for the lost dose in the second round of vaccination dosing.
The incident came when Governor Gavin Newsom expressed optimism about the state’s vaccination efforts.
