I did not know that, honestly quite surprised!
One thing to keep in consideration is that there is a very big evolutionary pressure for covid to get a mutation that bypasses the vaccine antibodies and still infect others, given that there are so many active infections still out there.
I now have good hope though!
To be fair humans are almost identical to chimpanzees biologically in many ways.
As long as the spike proteins tertiary structure has not changed to much from SARS to COVID, op could be correct. Emphasis on could.
