CV and mad panic behaviour

[Thryleon]

I must be writing in another language. I give up.

Nah I understand what you are stating, but apparently its as follows:

If you are vaccinated, your likelihood of transmission changes.  It may only halve that probability over a shortened duration, but its still reduced.

The math doesn't lie, but the argument is still the same on both sides.  The vaccine doesn't stop transmission (it is a limiting factor) of which might not be so limiting, because  positive people with fewer symptoms are more likely to "get on with it" which is an entirely different argument altogether.
