The vaccines are not stopping infections.

Looking at your link, it looks like the comparisons they make are purely based on COVID case counts and vaccination percentages. There are other factors that need to be considered: counties with higher vaccination rates in the USA are also likely to have a higher rate of testing, due to the politics of COVID (people who are more afraid of COVID are both more likely to be vaccinated and more likely to get a test when sick). At the country scale, it seems like something similar may be going on: they compare Portugal and Israel with the poorer countries of South Africa and Vietnam and state their case rates are similar. But different countries are using different policies which may affect the infection rate there. For instance, Vietnam has used lockdowns and border closures in recent months to slow the spread of the virus,[1] while Portugal with its high vaccination rates has recently removed almost all COVID restrictions.[2]

Using a country that had not given out boosters, like the USA or UK until recently, you’d get a better idea of the efficacy of the vaccine against Delta infections.
Moreover even in Israel the daily cases among double vaccinated are less than those among the unvaccinated. Look at the chart here https://www.ft.com/content/a1b2fd70-71b5-4e91-be0b-553b0e1e2... The line for “Two dose” cases per 100k among over 60 year olds is below unvaccinated since august 15 and continually remains less.
90%? No, that’s too high, but for instance data from public health England is saying the vaccines have around 15-45% efficacy (or 40-80% if doses 8+ weeks apart) against covid-19 infection after 25+ weeks, not 0%. https://mobile.twitter.com/EricTopol/status/1437890711139995...
Israel is about the highest examined and it is not high enough to know how a control group of vaccinated verse unvaccinated individuals would fare in a place where any other individual was vaccinated or bellow 12.
95% was in a retail lock down environment. In the current environment I am having hundreds of interactions a week with the unvaccinated and if I were unvaccinated would have far fewer, obviously a test run in this environment should achieve less than 95% and may appear that vaccination causes COVID because the economy is running on acceptable risks.
No, the virus spreads as a function of what actions you take and society slows based on what actions you take. If no one is dieing or going to hospital you choose economy and cases go up but if you are highly vaccinated then the consequences are not enough to not open up further and you run with higher numbers of known cases.
A correlation study is irrelevant to how effective vaccination is, just as any other intervention might appear ineffective if it allows systems to remove stricter restrictions with higher societal impact or makes people feel safe enough to participate in additional activities.
Some unvaccinated people in my town feel safe enough to do things because more people are safe and are doing them than in a town with no vaccination and more conservative average behavior, that doesn't mean the vaccine didn't work.
