It does not stop transmission (no ‘might’),
It might decrease it,
It might decrease the length of illness.
And I suspect the ‘might’ is really ‘does not’.
Might reduce severity of symptoms is a last ditch effort to give an unwitting public some reason to take an otherwise demonstrated to be useless vaccine.
Everyone knows it doesn’t stop yo7 from catching it, and it doesn’t stop you from spreading it.
The only other possible reason to take it is to mediate the severity of the symptoms so I would expect them to claim it did that, whether it really does or not. If they admitted it didn’t even do that, then there’s no justification for people to take the vax at all.
So yeah, I think they are lying on that last grab for trying to convince people to take it.
I’m not vaxxed, came down with COVID two days ago and started on the Ziverdo pack immediately. I’m pretty much normal now, less than 48 hours later.
