Because 'professionals' have no more clue than the rest of us. "Science is the belief in the ignorance of experts. When someone says ‘science teaches such and such’, he is using the word incorrectly. Science doesn’t teach it; experience teaches it" - Feynman. What you have here is the European "precautionary principle" in action. Whatever you do, don't get blamed for anything - whether you make any forward progress or not. At 60 you have a 1 in 100 chance of being dead in the next year anyway. A 1 in a million extra risk on top of that is a rounding error. The zero extra risk option is no longer available. I've had the AZ jab. It's perfectly fine and does the job. And those downvoting this post are saying that I should be dead instead.
