Israeli officials said that researchers have not found any severe COVID-19 cases among vaccinated people infected with the Omicron variant.

The CCP (Chinese Communist Party) virus strain—which was named Omicron by the World Health Organization (WHO) last week—has prompted fresh global panic as a number of countries imposed travel restrictions on southern African countries, where the variant was first located.

Dr. Sharon Alroy-Preis, Israel’s head of public health services, noted that the Omicron infection chance is “very high,” but he said that vaccinated people who have been infected with the variant only became slightly sick, local media reported.
