Don't know why you're getting downvoted.
You are essentially correct. There is a reduced effect after one shot. The first shots of AZ and Pfizer gives reduced protection at around 30%-70% from exhibiting symptoms according to recent UK and Canadian research.
Canada study: https://www.medrxiv.org/content/10.1101/2021.06.28.21259420v1.full.pdf
"We estimated that partial vaccination with BNT162b2 and mRNA-1273 were 55% and 70% effective, respectively, against symptomatic infection by currently circulating VOCs in Canada."
There's a lovely table in that paper that compares their respective effectiveness.
Importantly though, risk of death from the virus (including Delta variant) is significantly reduced after only one shot. Even one shot drastically decreases your risk of death but to get maximum protection and stop the spread, people should get both.

current vaccines don't protect from Delta variation (neither will do from Epsilon, Beta, Gamma, Theta and so on)
This is a false statement.

What exactly in your link contradicts what I said?

So yes, this virus causes brain damage.
But not permanent paralysis or meningitis... Also the demographics, route of infection, are different to polio.
The statement that COVID-19 causes nerve damage is also misleading - It can in some cases cause nerve damage in what is likely a very small percentage of cases (we do not know yet but if it is like its cousin SARS probably 0.04% of cases). Saying that loss of smell is caused by brain damage is just lies.
"Together, these data suggest that COVID-19-related anosmia may arise from a temporary loss of function of supporting cells in the olfactory epithelium, which indirectly causes changes to olfactory sensory neurons, the authors said."
People and papers love throwing around these flippant comparisons to polio, the Spanish flu, or smallpox. To make it sound scarier I suppose (and it might even be well intentioned) but all it does is make people distrustful of real science.
It's reminiscent of the Great Recession when everyone became an economist. We are all infectious disease scientists now.

Actually if you knew the facts about Polio you would understand the reason for similarities.
I've actually studied polio and work on vaccines. I think it's you who don't know about polio. Covid-19 is not polio.
-7 ( +5 / -12 )
But if we take Polio as an example,
Covid-19 is not polio.
-10 ( +5 / -15 )
That's a significant decrease in cases from yesterday. Perhaps people have begun to heed the state of emergency in light of recent delta variant news?
