DailyMail.com revealed the team had made a hybrid virus — combining Omicron and the original Wuhan strain — that killed 80 per cent of mice in a study.
The revelation exposes how dangerous virus manipulation research continues to go on even in the US, despite fears similar practices may have started the pandemic.
Professor Shmuel Shapira, a leading scientist in the Israeli Government, said: 'This should be totally forbidden, it's playing with fire.'
