What happens to the positive Covid cases?

Mazzer2:
Had to laugh yesterday when radio 5 lead headline was 3 million people have tested positive for covid in the UK, was yesterday or the day before, no it was since March hardly relevant since two weeks after getting it most will have recovered, also does that mean that those 3 million don’t need the vaccine as they say it’s rare to get it twice.

They haven’t committed themselves from the start of it as to the definition of ‘recovery’ nor provided the recovered count v cases let alone whether that means immunity.
They also seem to be saying that ‘recovery’ won’t mean no need for vaccination.
So let’s get this right.
They are saying ‘recovery’ doesn’t mean natural immunity.
Reinfection can and has occurred in known cases.
Which means the body doesn’t create any immunity in the form of a successful anti body response to it either way.
How does a vaccine supposedly work in that case.
A vaccine is only there to prime the body’s recognition and anti body response.
Reinfection after ‘recovery’ says no chance.
