California reported its highest daily death toll since the start of the pandemic with another 764 lives lost.

The state reported 23,024 new cases on Friday.

A CDC report released Friday indicates that the risk of severe allergic reactions with Moderna's vaccine is low. Severe, life threatening allergic reactions were seen in 2.5 cases per million people receiving the first dose of the Moderna COVID-19 vaccine, the report said.

Of the 4,041,396 first doses given as of Jan. 10, there were 1,266 (0.03%) reports of "adverse events," the report said. Among those, 108 "adverse events" were considered as possible cases of severe allergic reaction, including anaphylaxis. Ten cases were determined to be anaphylaxis (a rate of 2.5 anaphylaxis cases per 1 million doses) including nine people with a documented history of allergies or allergic reactions, the report said.

More people are testing positive for the United Kingdom’s variant of the coronavirus, and British Prime Minister Boris Johnson said Friday “there is some evidence that the new variant may be associated with a higher degree of mortality.”

U.K. Chief Medical Officer Chris Whitty stressed that the data is uncertain and there is a chance the new variant is increasing infections and mortality.

The U.K. has seen record daily death tolls several times this week.

There were 1,401 deaths in the last 24 hours.

New York state has used 97% of its allocated vaccine doses so far (for weeks 1 through 5) and will run out of doses by the end of the day, Gov. Andrew Cuomo said Friday.

Week 6 doses are currently being delivered, the governor said.

New York’s positivity rate has fallen to 5.65%, Cuomo said. Hospitalizations are also on the decline.

California's top epidemiologist has recommended pausing the administration of COVID-19 vaccines from Moderna's lot 041L20A due to "possible allergic reactions" that are under investigation.

"A higher-than-usual number of possible allergic reactions were reported with a specific lot of Moderna vaccine administered at one community vaccination clinic," Dr. Erica Pan, state epidemiologist for the California Department of Public Health, said in a statement late Sunday night. "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."

The California Department of Health said all of the affected individuals appeared to be experiencing "a possible severe allergic reaction during the standard observation period," which the U.S. Centers for Disease Control and Prevention says some people have experienced when receiving a COVID-19 vaccine.

More than 330,000 doses from that specific lot have been distributed to 287 providers across the state, with the shipments arriving between Jan. 5 and 12, according to the California Department of Public Health, which said it has not been notified of any other cluster or individual events related to this lot.

When asked for comment, a spokesperson for Moderna told ABC News: "Moderna acknowledges receiving a report from the California Department of Public Health (CDPH) that a number of individuals at one vaccination center in San Diego were treated for possible allergic reactions after vaccination from one lot of Moderna’s COVID-19 Vaccine. The company is fully cooperating with CDPH in investigating these reported adverse events. Consistent with the statement from CDPH, at this point Moderna is unaware of comparable adverse events from other vaccination centers which may have administered vaccines from the same lot."
