California’s State Epidemiologist is reportedly warning health providers to pause using a batch of Moderna Covid-19 vaccine “due to possible allergic reactions that are under investigation.”
The statement is understood to have been issued by Dr. Erica S. Pan, and referring to lot 41L20A of the Moderna vaccine states: “A higher-than-usual number of possible allergic reactions were reported with a specific lot of Moderna vaccine at one community vaccination centre.
“Fewer than 10 individuals required medical attention over the span of 24 hours. Out of an extreme abundance of caution and also recognising the extremely limited supply of vaccines, 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.
“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.
“While no vaccine or medical procedure is without risk, the risk of a serious adverse reaction is very small. While less data exists on adverse reactions related to the Moderna vaccine, a similar vaccine shows that the expected rate of anaphylaxis is approximately 1 in 100,000.”
It’s stated that more than 330,000 doses from this lot have been distributed to 287 providers across the state, the shipments had arrived in California between the 5th and 12th January. The state, it goes on, has not been notified of any other cluster or individual events related to the lot.
“The manufacturer, Centres for Disease Control and Prevention (CDC) and US Food and Drug Administration (FDA) are reviewing the lot and related medical information,” the statement concludes.
Ireland has administered its first doses of Moderna in the last few days.
