The World Health Organization has approved the Pfizer/BioNTech vaccine for "Emergency Use Listing," which it says “opens the door for countries to expedite their own regulatory approval processes to import and administer the vaccine.”

Emergency Use Listing also lets UNICEF and the Pan-American Health Organization "procure the vaccine for distribution to countries in need,” the WHO said.

“This is a very positive step towards ensuring global access to COVID-19 vaccines. But I want to emphasize the need for an even greater global effort to achieve enough vaccine supply to meet the needs of priority populations everywhere,” Dr Mariângela Simão, WHO assistant director-general for Access to Medicines and Health Products, said in a statement. “WHO and our partners are working night and day to evaluate other vaccines that have reached safety and efficacy standards. We encourage even more developers to come forward for review and assessment.”

In Yakima, Washington, 145 employees at a Costco have tested positive for COVID-19, the Yakima Health District said.

The outbreak was first announced on Christmas Eve with 68 staff members testing positive. Once testing was expanded to all employees, the number grew to 145.

“After reviewing the number of cases, and the timeline in which they were identified, there is evidence to show that this sharp increase in cases mimics the type of activity that happens after some sort of super- spreader event where multiple people are infected at the same time,” the health district said.

“For Costco specifically, site-wide testing was recommended given the large number of infected employees. When site-wide testing is recommended, the organization provides testing to all employees, regardless of whether they were identified as an initial close contact to a positive COVID-19 case or not,” the health district continued. “Costco will continue to provide on-going site-wide testing for their employees moving forward to monitor the outbreak.”

Forty-two people in West Virginia received the Regeneron monoclonal antibody treatment instead of the Moderna vaccine on Wednesday at a vaccination clinic hosted by staff at the Boone County Health Department, the West Virginia National Guard confirmed to ABC News.

Medical experts with the Joint Interagency Task Force do not believe there is any risk of harm to these 42 individuals. Everyone who received the monoclonal antibody has been contacted, or is in the process of being contacted, according to the West Virginia National Guard.

“The moment that we were notified of what happened, we acted right away to correct it, and we immediately reviewed and strengthened our protocols to enhance our distribution process to prevent this from happening again,” Maj. Gen. James Hoyer, Adjutant General of the West Virginia National Guard, said in a statement.

The Regeneron treatment was administered intramuscularly, like a traditional vaccination, according to the West Virginia National Guard. The Regeneron treatment, which was given FDA emergency authorization in November, is normally given as an intravenous infusion, not an intramuscular injection.

The recommendation from the Centers for Disease Control and Prevention is that for those who receive antibody treatments, "vaccination should be deferred for at least 90 days, as a precautionary measure until additional information becomes available, to avoid interference of the antibody treatment with vaccine-induced immune responses."

A West Virginia National Guard official told ABC News that "there are no concerns that this will set individuals back 90 days" and that "all 42 individuals are being offered the vaccine today."

New York State Police will refer ParCare Community Health Network to the New York Attorney General’s office for allegedly misappropriating the Moderna vaccine, Gov. Andrew Cuomo said Monday.

State Health Commissioner Howard Zucker said the Orange County-based health care provider obtained the vaccine under false pretenses, moved it to Brooklyn, and gave it to people who weren't on the priority list. While ParCare is the only organization currently under criminal investigation, the governor said recipients of the vaccine who violated the state's distribution plan could also face charges.

"Whenever you have a valuable commodity that is being dispensed you should expect fraud," Cuomo said.

Under New York's current plan for "1A" distribution, only medical workers, first responders and nursing home staff members are allowed to receive the coronavirus vaccine. Other groups will follow in future rounds.

"We take this very seriously," Zucker said in a statement last week. "Anyone found to have knowingly participated in this scheme will be held accountable to the fullest extent of the law."

New York State Police and other investigators were at the ParCare location in Borough Park on Saturday night.

A spokesman for ParCare told ABC News Sunday evening that it is cooperating with the state investigation and will return its unused vials. ParCare received 2,300 doses of the Moderna vaccine, and 869 of those doses have already been administered, according to the spokesperson.

"ParCare followed all NYS DOH procedures for obtaining the Moderna vaccine and was approved by NYS DOH for distribution and by CDC as a network site. As a result, we have properly received the vaccines and have provided the documentation regarding the proper receipt of the vaccines to the NYS DOH," the spokesperson told ABC News.

With regards to the patients who received their first shot, ParCare said it will be "working with the state to ensure that we provide the second dose for our patients."
