Moderna says it’s investigating reported allergic reactions to COVID-19 vaccine

Moderna said Tuesday that it is investigating reported allergic reactions from one batch of its COVID-19 vaccine after California recommended pausing vaccinations.

State epidemiologist Erica Pan recommended on Sunday that health care providers pause administering doses from lot 041L20A while the state investigates a “higher-than-usual number of possible allergic reactions” that were reported with doses that were administered at a community vaccination clinic.

In a statement on Tuesday, Moderna said it “acknowledges receiving a report from the California Department of Public Health (CDPH) several individuals at one vaccination center in San Diego were treated for possible allergic reactions after vaccination” from the lot.

The company said it’s unaware of “comparable clusters” of adverse events from other vaccination centers that may have administered doses from the same lots.
