California’s top epidemiologist recommended that healthcare providers stop administering a specific batch of Moderna’s COVID-19 vaccine after a series of allergic reactions Sunday night at Petco Park, according to the Los Angeles Times.

The reactions occurred at San Diego County’s drive-through vaccination site at Petco Park, according to the Los Angeles Times. California monitors people for at least 15 minutes after they receive the vaccine to see if they have a reaction, according to CDC guidelines. While the affected individuals’ specific symptoms were not revealed, they were described as “severe.”

Dr. Erica Pan explained the move was driven by “an extreme abundance of caution.” She told providers to halt using those specific doses until an investigation by state, federal, and company officials is completed.

“A higher-than-usual number of possible allergic reactions were reported with a specific lot of Moderna vaccine administered at one community vaccination clinic,” Pan said in a statement. “Fewer than 10 individuals required medical attention over the span of 24 hours.”

“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 and pause the administration of vaccines from Moderna Lot 041L20A until the investigation by the CDC, FDA, Moderna and the state is complete,” Pan added.

California has received approximately 330,000 doses of the specific Moderna batch. This accounts for about 10% of both the Moderna and Pfizer vaccines that have been delivered to the state.

“That state has not been notified of any other cluster or individual events related to this lot,” the statement read.
