Israel approves 4th vaccine dose for people 60 and over

Israel's Ministry of Health approved a fourth dose of COVID-19 vaccine for health care workers and people over 60 years old, Prime Minister Naftali Bennett said.

"Israel will once again be pioneering the global vaccination effort," Bennett said at a press conference in Jerusalem. "Omicron is not Delta -- it’s a different ball-game altogether."

Fourth doses will be administered four months after booster shots, Bennett said.

More than 100,000 Americans are hospitalized with COVID-19

More than 100,000 Americans are currently hospitalized with COVID-19, according to data from the U.S. Department of Health and Human Services.

A total of 103,329 people are receiving medical care, which is an increase of 130% from the number recorded two months ago.

Of those patients, more than 17% -- about 18,000 -- are in intensive care units.

The newly updated figure is just shy of the hospitalization peak seen during the summer wave fueled by the delta variant, when 104,000 Americans were hospitalized with COVID in early September.
