more misinformation @Malahaha. I recognise a lot of it from Yeadon's ramblings.
"Asymptomatic" people, aka healthy people, do not spread the infection. To be able to be infectious you'd have to have a high viral load, and then you'd have symptoms, and stay in bed or at home. This is another one of the untruths being spread in order to fan the fear, and to divide us, so that we are afraid of each other.
Both asymptomatic and asymptomatic transmission have been proven to occur - there's a robust body of literature proving this. This is why it has been so hard to contain coronavirus. It is not automatically true to say a high viral = severe symptoms in all people, or that a high viral load is needed in order to infect someone else.
And as we know by now, being vaccinated does not mean you won't catch Covid, or can't spread it. There's virtually no difference between the jabbed and the unjabbed as far as getting and spreading infection is concerned. Yet the former choose to look down on the latter as if we had leprosy.
Vaccination reduces the chance of a person both getting coronavirus, and infecting other people. On a population level, this makes a huge difference (particularly when you consider mass events and crowded places) in terms of transmission.
