COVID-19 vaccinations are expected to begin in Germany "in the very first days" of 2021, according to German Chancellor Angela Merkel’s chief of staff.

In an online interview Sunday with German newspaper Bild, Helge Braun said he and Merkel will get vaccinated "when it's our turn." The trained doctor also noted that he's prepared to help vaccinate people himself.

"That won’t work at every hour of the day or night as chief of staff, but at the weekend I’m prepared to join in," Braun told the Bild.

The European Union's drug regulator is expected to make a decision by Dec. 29 on approving the first COVID-19 vaccine for use. In the meantime, Germany is preparing special vaccination centers.

There were 175,663 new cases of COVID-19 confirmed in the United States on Sunday, according to a real-time count kept by Johns Hopkins University.

It's the 34th straight day that the U.S. has reported over 100,000 newly diagnosed infections. Sunday's tally is less than the country's all-time high of 227,885 new cases confirmed on Dec. 4, according to Johns Hopkins data.

An additional 1,114 deaths from the disease were also registered nationwide on Sunday, down from a peak of 2,879 fatalities on Dec. 3, according to Johns Hopkins data.

COVID-19 data may be skewed due to possible lags in reporting over Thanksgiving followed by a potentially very large backlog from the holiday.

A total of 14,760,627 people in the U.S. have been diagnosed with COVID-19 since the pandemic began, and at least 282,312 of them have died, according to Johns Hopkins data. The cases include people from all 50 U.S. states, Washington, D.C., and other U.S. territories as well as repatriated citizens.

Much of the country was under lockdown by the end of March as the first wave of pandemic hit. By May 20, all U.S. states had begun lifting stay-at-home orders and other restrictions put in place to curb the spread of the novel coronavirus. The day-to-day increase in the country's cases then hovered around 20,000 for a couple of weeks before shooting back up over the summer.

The numbers lingered around 40,000 to 50,000 from mid-August through early October before surging again to record levels, crossing 100,000 for the first time on Nov. 4 and reaching 200,000 for the first time on Nov. 27.

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.
