The first vaccines in the U.S. have now left the Pfizer facility and are on their way to all 50 states.

Two main trucks left on Sunday morning -- an additional truck will come in later to pick up a few boxes and take them to the U.S. territories.

On Monday Pfizer has an order for another 400 boxes of the vaccine as well as an order for a slightly less amount of boxes on Tuesday, the company said.

The first shipments are expected to arrive at 145 sites on Monday, 425 sites on Tuesday and another 66 sites on Wednesday, Gen. Gus Perna of the Trump administration's Operation Warp Speed vaccine program said.

At those sites, the vaccines will be paired with ancillary kits to assist with the vaccinations. The kits contain needles, syringes, alcohol swabs, diluent, safety gear and vaccine reminder cards.

Starting Wednesday, Dec. 16 through Jan. 10, all non-essential stores and schools will be closed in Germany and social meetings will be limited to five people from two households, with an exception made for the Christmas period from Dec. 24 to Dec. 26 when four more people beyond a household will be allowed.

No exceptions will be made for New Year's Eve.

COVID-19 transmissions remain high in the country despite softer restrictions in place. As of Dec. 13, the Robert Koch Institute reported a total of 20,2000 new cases and 321 deaths, bringing the totals to 1,320,716 and 21,787, respectively.

Germany had initially planned for a "semi-lockdown," allowing for a holiday exemption from Dec. 23 to Jan 1 where up to 10 people from two households could meet but those plans were scrapped in favor of these new rules.

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.
