Breaking down Israel's Covid-19 strategy

Almost half of all Israelis have now received Covid-19 vaccines. Thanks to a world-leading inoculation programme, the country is one of the first developed nations to now be rolling back its latest round of restrictions.

For more on Israel's Covid-19 strategy, we speak to Professor Cyrille Cohen, director of the Immunotherapy Lab at Bar-Ilan University. He's also a member of Israel's advisory council on vaccines.
