The issue reportedly stemmed from an issue with the syringes
An estimated 4,300 California individuals received a smaller coronavirus vaccine than they should have due to an issue with syringes.
According to KTVU, the Oakland Colliseum site received orange-capped syringes that left a third of the vaccine stuck on the bottom of the plastic container. The problem was eventually detected on Monday but individuals vaccinated before that point reportedly only received 0.2 mL of the Pfizer vaccine instead of the optimal 0.3 mL.
The California Office of Emergency Services, which helps run the site with the Federal Emergency Management Agency, said high-level meetings were held on Tuesday afternoon after whistleblowers alerted the issue.
Cal OES spokesman Brian Ferguson reportedly said he didn’t think anyone was formally underdosed and that there wasn’t any need to contact the individuals who received the lower vaccine amount.
On Wednesday, he said authorities were told that the dosing fell within medical guidelines and protocols.
Dr. Peter Chin-Hong, an infectious disease expert, reportedly said the patients were “likely protected” and could make up the lost dosage in the second round of vaccine dosing.
The incident came as Gov. Gavin Newsom expressed optimism over the state’s vaccination efforts.
