Expanding on a sibling comment's reference to Simpson's paradox is the following analysis of the data:

Basically, Israel is doing quite well even still. Yes, there's a reduction in efficacy, and yes there's breakthrough infections, but your risk of serious outcomes is still reduced by ~80%+, even in older populations _when correctly compared to unvaccinated older populations_.

Isn't what you ultimately care about in terms of policy the effectiveness on a population level? Of course you hit diminishing returns, when you start vaccinating people that were not at risk in the first place. I'm not arguing against getting the vaccine btw., I'm vaccinated myself. It is just disappointing that it alone won't solve the problem.
