Facing a backlog in administering coronavirus vaccines, U.S. states are asking medical and nursing students, and even firefighters, to help give the shots and free up healthcare workers battling a raging pandemic at overcrowded hospitals.

A winter storm that blasted the U.S. Northeast with snow, rain and gusty winds was likely to dump a foot (30 cm) or more of snow on parts of New England before heading out to sea.

Pfizer, COVID vaccine

The United States authorized the use of Pfizer Inc’s Covid-19 vaccine on Dec. 11, with the first inoculations expected within days, marking a turning point in a country where the pandemic has killed more than 295,000 people.

The United States’ daily death toll from Covid-19 surpassed 3,000 for the first time, prompting pleas for Americans to scale back Christmas plans even with vaccines on the cusp of winning regulatory approval.

A 90-year-old grandmother became the world’s first person to receive a fully tested Covid-19 shot on Dec. 8, as Britain began mass-vaccinating its people in a global drive that poses one of the biggest logistical challenges in peacetime history.

The World Health Organization tightened guidelines on wearing face masks, recommending that, where Covid-19 is spreading, they be worn by everyone in health care facilities and for all interactions in poorly ventilated indoor spaces.

One in seven cases of Covid-19 reported to the World Health Organization is a health worker and in some countries that figure rises to one in three, according to the WHO.
