California state health officials have ordered a temporary halt in administering the Moderna coronavirus vaccine after a group of people appeared to have an allergic reaction at one clinic.

According to The Daily Wire, California state epidemiologist Dr. Erica Pan issued the notice on Sunday “out of an extreme abundance of caution.” 

The order affects roughly 330,000 doses of the Moderna vaccine against COVID-19 and 287 providers that received units.

Dr. Pan explained, “Our goal is to provide the COVID vaccine safely, swiftly and equitably. A higher-than-usual number of possible allergic reactions were reported with a specific lot of Moderna vaccine administered at one community vaccination clinic. Fewer than 10 individuals required medical attention over the span of 24 hours.”

She added, “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. We will provide an update as we learn more.”

The California Department of Public Health reported a handful of vaccine recipients appeared to be experiencing a “possible severe allergic reaction” to the vaccine.

The health department said, “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.”

In December, Ohio Gov. Mike DeWine said that roughly 60% of nursing home workers had opted out of taking the vaccine. 

In New York City, about half of EMS workers have also decided against getting the vaccine.


In California, surveys of health care workers at various hospitals have also shown a reluctance to take the vaccine The Los Angeles Times reported that about 50% of workers at St. Elizabeth Community Hospital in Tehama County has refused to take the vaccine while about 20% of workers at Providence Holy Cross Medical Center in Mission Hills have also declined.
