Forgot to mention Israel, which you asked about in your post:
As I said elsewhere about two days ago, the numbers in Israel show breathrough for several reasons: starting early, starting with the oldest Israelis, using the best vaccine but they all start to lose effectiveness, everyone now agrees, the statistical quirk that I first read in the Times about the PERCENTAGE of breakthrough cases automatically increasing mathematically as the number of the unvaccinated decreases, and very probably the increased social interaction that came as a big relief but with the danger of infection.
There might be more reasons.
As I’m sure you know, Israel has started giving out boosters already. They do the right thing for their people and should be commended for it, instead of people seizing the negative and trying to make a case for their point of view.
The right thing to do is to leave the choice up to individuals whether or not they want the jabs and have the meddling hands of power hungry bureaucrats out of it.
Every time you go out in public, you take a risk - even before Covid.
Same rule should apply now. I’m not scared of this.
