UNC Health of Chapel Hill, North Carolina, confirmed it acquired 725 COVID vaccines origanally intended for the Orange County health department on Thursday night, WTVD reported.

In an emailed statement, the Orange County health department said, "UNC Health was notified that Orange County had a number of vaccine vials available for immediate use.

"UNC Health worked closely with Orange County to ensure that all of the vaccines would be used with zero waste and that all of these shots would go to either Phase 1-A personnel or staff who work with COVID-19 patients in some capacity.

"This cooperation was a success, and all of the available stock was used appropriately."

Florida Gov. Ron DeSantis won’t allow local governments to enforce their mask mandates, causing frustration among some mayors, reported WPLG.

“We can give out citations and we can urge people and we can give out masks, and we’ve given out thousands, but we don’t have the ability to mandate it in any way that’s effective,” Miami Beach Mayor Dan Gelber told WPLG.

“He continues to say that we don’t want the federal government to tell us what to do, states are better because it should be local controlled,” said Broward County Mayor Steve Geller. “But when we here in Broward are asking for local control, we’re not getting it."

A Virginia state senator has died of the coronavirus, officials announced.

State Sen. Ben Chafin, 60, was hospitalized for the last two weeks with the virus, according to a press release. The Republican lawmaker had served in the state Senate since 2014. He is survived by his wife and three children, according to his office.

Gov. Ralph Northam ordered the Virginia state flag to be lowered immediately over the state Capitol and remain at half staff until Chafin's internment.

"This is sad news to begin a new year with the loss of a kind and gracious man. May we all recommit to taking extra steps to care for one another," the governor said in a statement.

Public Health England does not recommend mixing COVID-19 vaccines from different suppliers, according to the agency's head of immunizations, Dr. Mary Ramsay.

"We do not recommend mixing the COVID-19 vaccines -- if your first dose is the Pfizer vaccine you should not be given the AstraZeneca vaccine for your second dose and vice versa," Ramsay said in a statement Saturday. "There may be extremely rare occasions where the same vaccine is not available, or where it is not known what vaccine the patient received. Every effort should be made to give them the same vaccine, but where this is not possible it is better to give a second dose of another vaccine than not at all."

The clarification comes amid questions over the British government's updated guidance on COVID-19 vaccines, which now says that if individuals who received the first shot go to an immunization site where that same vaccine is not available for a second shot, or if the first vaccine received is unknown, "it is reasonable to offer one dose of the locally available product to complete the schedule."

"This option is preferred if the individual is likely to be at immediate high risk or is considered unlikely to attend again," the guidance adds.

The guidance, which was updated Thursday, also notes that "there is no evidence on the interchangeability of the COVID-19 vaccines although studies are underway," and thus "every effort should be made to determine which vaccine the individual received and to complete with the same vaccine."

Next week, the United Kingdom is set to begin distribution of a COVID-19 vaccine developed by England's University of Oxford and manufactured by British-Swedish pharmaceutical giant AstraZeneca, after the drug was approved Wednesday for emergency supply. Another COVID-19 vaccine developed by U.S. pharmaceutical giant Pfizer and its German partner BioNTech was approved in the U.K. on Dec. 2 and rollout began a week later.
