California health officials are calling on COVID-19 vaccine providers to stop using a batch of Moderna’s shots after a handful of people who were inoculated at the same site all had allergic reactions.
Fewer than 10 people reported reactions after recieving doses at a San Diego vaccination site last week, according to FOX5 San Diego.
“All appeared to be experiencing a possible severe allergic reaction during the standard observation period – a type of adverse event that the CDC reports some people have experienced when receiving a COVID-19 vaccine. The vaccine site switched to another lot of Moderna vaccine after closing for a few hours,” the California Department of Public Health said.
The mass vaccination site at Petco Park, the home of the Padres, opened Jan. 11 to deliver vaccines to healthcare workers on the state’s priority list, the station reports.
Nearly a third of a million doses from the Moderna batch were sent to 286 other providers in the Golden State, with no other news of bad reactions.
Still, officials say it’s better to be safe than sorry.
“Out of an extreme abundance of caution and also recognizing the extremely limited supply of vaccine, we are recommending that providers use other available vaccine inventory,” the news release said.
Officials noted that there is a degree of risk to any vaccine or medical procedure, and it’s highly unlikely anyone will suffer a negative reaction.
Moderna, the CDC and the FDA are all reviewing the batch and hope to learn more this week. Replacement doses are not immediately available, according to the FOX5.
Federal officials have previously noted that a few vaccine trial participants who had cosmetic facial fillers suffered side effects.
