That's just wrong. Why do people keep claiming this? Consensus immunity for Pfizer against delta is still in the 60-80% range, which while less than the 95% measured against earlier variants is vastly higher than the unvaccinated. (Though to be fair this is hard to measure against the confounding background that the vaccinated tend to be better at other mitigation strategies too.)

Even the Israel data you cite, which is an outlier, measured 39% effectiveness, which is STILL twice as good as being unvaccinated.

Those 80% and higher efficacies are against symptomatic COVID and hospitalization. Not against getting infected and getting infectious. This efficacy was high initially, but is reported to be decreasing, and currently at 40% for Pfizer [1]:

That study is still an outlier. But I repeat, because you don't seem to understand the point: even if it's that low, and even if transmissibility is completely unaffected, it means that an unvaccinated person will spread TWICE AS MANY CASES as a vaccinated one. That's the difference between a pandemic and a contained endemic disease right there.

Get. Your. Vaccine.

40% efficacy for preventing spreading is quite poor. There are other strategies of similar or better efficacy for preventing spreading like limiting contact with people, using masks, vitamin D, being on ivermectin. If you were a marketing department of a pharma company selling vaccines for preventing spreading, you would not be very convincing.
