Israel on Sunday started human trials of an experimental coronavirus vaccine developed at the Israel Institute for Biological Research, one of dozens of clinical trials underway worldwide. The first two volunteers were inoculated at Sheba Medical Center at Tel HaShomer and Hadassah Ein Kerem Medical Center in Jerusalem, respectively. In the next phase, the vaccine will be tested on another 80 volunteers, and in the third and final phase, it will be administered to some 30 thousand people. Some volunteers will receive a dose of the vaccine and others a placebo. Prof. Cyrille Cohen, head of the immunotherapy laboratory at Bar-Ilan University and a member of the Health Ministry's advisory committee on the coronavirus vaccine in Israel, spoke to KAN reporter Naomi Segal about the vaccine trial.
