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.

Mayo Clinic lays off 1% of staff for vaccine noncompliance
Mayo Clinic said it will lay off about 1% of its staff for failing to get at least one dose of the COVID-19 vaccine by a company deadline.
"While Mayo Clinic is saddened to lose valuable employees, we need to take all steps necessary to keep our patients, workforce, visitors and communities safe. If individuals released from employment choose to get vaccinated at a later date, the opportunity exists for them to apply and return to Mayo Clinic for future job openings," Mayo Clinic said in a statement to ABC.
Last October, Mayo Clinic had set a Jan. 3 deadline for all employees to get at least their first vaccine dose or face dismissal.
The health care organization said the number of staffers being let go was "comparable to what other health care organizations have experienced in implementing similar vaccine requirement programs."
Mayo Clinic employs about 73,000 people, according to its website.
