US-based drugmaker Moderna has confirmed that it has received a report from California’s health department that many individuals at one vaccination centre in San Diego were treated for possible allergic reactions after vaccination from 1 lot of the provider’s COVID-19 vaccine.

The business is”fully cooperating” with the California Department of Public Health (CDPH) in investigating these reported adverse events, Moderna said on Tuesday.

The confirmation comes after California State Epidemiologist Dr Erica Pan on Sunday recommended stopping the administration of lot 41L20A of the Moderna COVID-19 vaccine because of possible allergic reactions that are under investigation.

“A higher-than-usual number of potential allergic reactions were reported with a specific bunch of Moderna vaccine administered in a single neighborhood vaccination clinic. Fewer than 10 individuals required medical care over the span of 24 hours,” said Dr Pan.

“Out of an extreme abundance of caution as well as 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 Bulk 041L20A before the analysis by the Centers for Disease Control and Prevention (CDC), US Food and Drug Administration (FDA), Moderna and the state is complete.”

All appeared to be experiencing a possible severe allergic reaction throughout the conventional observation period — a sort of adverse event that the CDC reports some individuals have experienced when receiving a COVID-19 vaccine.

The vaccine site switched to a different lot of Moderna vaccine after closure for a few hours.

Moderna said that it is unaware of comparable clusters of adverse events from other vaccination centres that may have administered vaccines from the same lot, or from other Moderna lots.

“Moderna confirmed that a total of 1,272,200 doses were created in batch number 041L20A, with nearly a million doses (964,900) already distributed to approximately 1,700 vaccination sites in 37 states,” the firm said in a statement.

While Moderna said it does not know how many doses might have ended up in the arms of people, it did report that the lot was sent between January 4-8, and thus it anticipates a substantial portion of the distributed doses have already been used.

Moderna said a comprehensive review of the production intermediates and final drug product was conducted including raw materials, batch records, release and characterization testing results, and Moderna shipping and storage records.

“The review confirmed that all criteria for product release of lot 041L20A were met,” the announcement added.
