Oh, what a surprise, more insults from somebody who can't even use the correct terminology and claims that "death rate" is "the most obvious and only relevant statistic when it comes to describing vaccine effectiveness".
If you had ANY interest in facts, it would take you only a moment of thought to realize that neither the (correctly defined) death rate nor case fatality rate can be "the most obvious and only relevant statistic when it comes to describing vaccine effectiveness", since they make no distinction between people who were vaccinated back at the beginning of the year and people who just got their shots.
You would then also realize that "the most obvious and only relevant statistic" is case fatality rate as a function of time since vaccination. You would plot that with time since inoculation on the x axis and case fatality rate on the y axis.
A few seconds of googling would then lead you to a couple of big recent studies:

In short, protection against infection wanes rapidly, protection against hospitalization and death wanes more slowly, and booster shots help, as exemplified by the Israeli example. From the Science article:
This phenomenon has been most comprehensively monitored in Israel, where high levels of transmission of the Delta variant led to a resurgent outbreak in mid-June 2021 (16), despite a successful nationwide campaign to vaccinate the population (17). Israel authorized boosters of the Pfizer-BioNTech vaccine for adults age ≥ 60 years in July 2021 and extended this authorization to adults age ≥ 50 years in August 2021 (18). Rates of infection and severe illness subsequently declined in those who received a booster (19).
