Israel should provide a pretty definitive example soon enough as to the true efficacy of the various vaccines, and the degree to which any of them have the so-called "sterilising immunity" - the ability to prevent the passing on of the virus in addition to the immunological benefit.
Last I read - over 1 million people in a population of 8.8 million vaccinated. 24/7 operation throughout the country, with people actively being contacted and encouraged to benefit. Their readiness for a biological warfare attack has undoubtedly stood them in good stead.
Seems Netanyahu has used this opportunity to rebuild his credibility somewhat., at least with his own electorate as opposed to any other group. As much as I profoundly disagree and despair at some of the geopolitical policies of the Israeli state, this is impressive.
