Nevada Gov. Steve Sisolak extended his state's coronavirus restrictions through at least Jan. 15 as COVID-19 cases and deaths surge in the Silver State.

Nearly every state in the U.S. reports more than 100 people hospitalized per million, according to the COVID Tracking Project. However, Nevada reports 592, which translates into one out of 1,700 people in the state, according to the project.

"We continue to see an increase of hospitalizations statewide with almost 1,700 Nevadans battling COVID as of Friday," Sisolak said at a press conference Sunday.

The governor also announced Sunday that he would sign an order to place a moratorium on most residential evictions in Nevada.

Since the start of the pandemic, Nevada has had more than 186,000 cases, with at least 2,529 deaths.

The first vaccinations in the state of Washington could be distributed as early as Tuesday, Gov. Jay Inslee said.

The initial shipment of the Pfizer vaccine arrives in the state on Monday.

"This is just fantastic news ... we are getting this vaccine," the governor said, adding he will get the vaccine himself when it is appropriate for his age group.

"Health care workers and long-term care residents will receive the vaccine first," he said.

The Korea Disease Control and Prevention Agency reported 1,030 newly diagnosed COVID-19 cases on Sunday, bringing the country's total to 46,645.

This is the first time since the beginning of the pandemic that South Korea broke the 1,000 mark in new cases and follows Saturday's record of 950 new cases.

Yonhap reports that President Moon Jae-in held an emergency meeting and called the current situation "the worst crisis" since the outbreak began and a "desperate time" when the government should make an all-out effort stem further infections.

Authorities in the U.K. were investigating reports of two allergic reactions to the coronavirus vaccine from Pfizer/BioNTech -- a day after the country started its historic inoculation program.

Dr. June Raine, head of the UK regulatory body Medicines and Healthcare products Regulatory Agency (MHRA), said the agency was looking at two reports of allergic reactions to the vaccine, which rolled out yesterday.

"We know from the very extensive clinical trials that this wasn’t a feature but if we need to strengthen our advice... we get that advice to the field immediately,” said Raine.

The vaccine is believed to be both safe and 95% effective, according to Pfizer/BioNTech. The U.S. Food and Drug Administration was set to hold a hearing for emergency use of the drug on Thursday.

“There have been two cases of anaphylactoid reactions in individuals with a strong past history of allergic reactions both of whom carried an adrenaline auto injector,” the National Health Service (NHS) said in a statement on Wednesday. “These individuals developed symptoms of anaphylactoid reaction shortly after receiving the vaccine. Both recovered after appropriate treatment. We are seeking further information and will issue further advice following investigation.”

Pfizer/BioNTech have not yet commented on these latest findings.

Professor Stephen Powis, national Medical Director for the NHS, said: “As is common with new vaccines the MHRA have advised on a precautionary basis that people with a significant history of allergic reactions do not receive this vaccination after two people with a history of significant allergic reactions responded adversely yesterday. Both are recovering well.”
