It is true what you are saying here Umair, and availability of vaccines for all in UK will suffer for sure. A partially vaccinated population might even be more damaging than none vaccinated, unfortunately.

Of course an attacker adjusts their angle of attack in response to a weak defense, hence we see variants.

Has it struck anyone that we will be perfect lab rats for profit driven vaccine research around the world?

Why bother making new variants in a lab if we can have a factory in the street?
