NY health provider may have fraudulently obtained COVID-19 vaccine

A representative from Virgin Atlantic told ABC News it will implement a new protocol for United Kingdom travelers that mandates a COVID-19 test before boarding flights to the U.S.

"With the health and safety of our customers and people always our number one priority, we will require all travelers to present evidence of a negative LAMP or PCR COVID-19 test, taken up to 72 hours prior to departure, including on-site at the airport," the representative said in a statement.

The new requirement goes into effect on Dec. 24.

The change comes after New York Gov. Andrew Cuomo called on international airlines to test passengers for the coronavirus before getting on a plane to the U.S. A variant of the virus has been discovered in Britain and prompted several countries to suspend travel from the U.K.

California’s stay-at-home orders -- currently in effect for 98% of the state’s population -- will likely be extended, Gov. Gavin Newsom said.

A three-week stay-at-home order was issued in a region of California when it fell below 15% intensive care unit capacity. The stay-at-home order can only be lifted when ICU capacity returns to above 15%.

Two of the five regions, Southern California and San Joaquin Valley, currently have 0% capacity.

The Bay Area and the Greater Sacramento area also under a stay-at-home order. Northern California is the state’s only region not under the order.

California has 17,190 coronavirus patients in hospitals -- a 63% increase in the last two weeks.

California has deployed 607 state workers to 75 health care facilities in 24 counties that were requesting extra assistance. Newsom said he has asked the Department of Defense for 10 teams of 20 health care workers, and he is also asking a team that’s been working in Imperial County to extend its stay until the end of January.

President-elect Joe Biden was administered the Pfizer vaccine on Monday afternoon at ChristianaCare Hospital in Delaware.

Dr. Jill Biden was vaccinated earlier on Monday.

Dr. Anthony Fauci is expected to get vaccinated Tuesday, according to the National Institutes of Health.

President Donald Trump has not been vaccinated because doctors wanted him to wait after he received monoclonal antibody treatment following his COVID-19 diagnoses, U.S. Surgeon General Jerome Adams said Monday.

"His doctors, who I've spoken with, wanted people to understand that if you have recently been given monoclonal antibodies, the FDA says you should wait several weeks before you get vaccinated,” Adams told reporters. “So the reason the president has not gotten vaccinated yet is because his doctors have advised him to wait."

Injections of the newly authorized Moderna vaccine are now underway in the U.S.

In Boston, health care workers at the East Boston Neighborhood Health Center were among the first people to receive Moderna's vaccine. Dr. Jaime Gallegos, the first staffer to get the vaccine, held a sign that said, "Take that, COVID!"

The first cases containing the Moderna vaccine -- which was authorized by the FDA on Friday -- were seen Sunday morning being rolled out from a facility in Olive Branch, Mississippi, to be shipped to the FedEx hub in Memphis, Tennessee, for nationwide distribution.

The doses were packed into insulated coolers with specialized cold packs and a temperature monitor, according to pharmaceutical distribution company McKesson.
