The COVAX global vaccine-sharing program has delivered 1 billion COVID-19 vaccine doses, one of the organizations which manages it said on January 15.

The Omicron variant of the coronavirus is spreading faster than the Delta variant and is causing infections in people already vaccinated or who have recovered from the Covid-19 disease, the head of the World Health Organization (WHO) said on December 20.

Most of the 43 Covid-19 cases caused by the Omicron variant identified in the United States so far were in people who were fully vaccinated, and a third of them had received a booster dose, according to a U.S. report published on December 10.

Eighty percent of Americans 12 and older have received at least one Covid-19 vaccine dose, White House coronavirus coordinator Jeff Zients said on November 17, highlighting a promising milestone in efforts to curb the spread of the deadly virus.

Half of children aged 12 to 17 have received at least their first vaccination dose against Covid-19, and that age group has the fastest growth rate in vaccinations, the White House said on Aug. 27.

As the work force returns to the office, life science companies are having to take their stance on vaccine policy. Some have chosen a strict mandate, others a mandate with options, and others have yet to issue an edict.
