RIVERSIDE (CNS) – With the supply of COVID-19 vaccines already a concern, the state is warning providers to stop administering a particular batch of the Moderna vaccine due to a group of people who experienced allergic reactions to the shot at a San Diego clinic.
But the restriction is not expected to impact Riverside County vaccination efforts.
“A higher-than-usual number of possible allergic reactions were reported with a specific lot of Moderna vaccine administered at one community vaccination clinic,” state epidemiologist Dr. Erica S. Pan said in a statement late Sunday.
“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. We will provide an update as we learn more.”
Meanwhile, due to the Martin Luther King Jr. Day holiday, Riverside County health officials did not provide updated COVID-19 numbers Monday. The next update is expected Tuesday.
Since the pandemic began, Riverside County has recorded 233,899 cases and 2,517 deaths, according to the Riverside University Health System.
The agency does not provide updated COVID-19 statistics on weekends.
On Friday, for the second day in a row, Riverside County reported a record number of COVID-19 deaths, with the total exceeding 100 for the first time in the pandemic.
RUHS reported 118 additional COVID-19 deaths Friday, with many of them the result of delayed reporting. Officials said one of those deaths occurred in October, while nearly one-third occurred in December and the remainder within the past two weeks.
San Diego County health officials confirmed last week that a half-dozen health care workers who were inoculated at the vaccination center at Petco Park had suffered allergic reactions.
In Riverside County, health officials said the Moderna vaccine doses being used at county-run vaccination clinics scheduled for this week are not from the affected batch.
Officials also said that shipments of vaccine distributed from the county to private providers countywide are also not thought to be from the affected batch.
Adverse reactions at both county-run vaccine clinics and private entities within Riverside County have so far been rare, officials said.
“We are checking with our partners, and at this time, we have not found any within Riverside County providers. We are also not aware of providers that have seen adverse reactions. We continue to see that adverse reactions are rare,” county Executive Office spokeswoman Brooke Federico said.
According to the state, more than 330,000 doses of the Moderna vaccine were included in the affected lot, and they were distributed to 287 locations across California. The 330,000 doses are roughly 10% of the 3.2 million doses the state has received overall from Moderna and Pfizer.
No other significant issues with allergic reactions have occurred at any other location where the affected lot was distributed, according to the state.
It was not clear which other locations received the affected doses.
