If I went to South America and toured the jungles I would in all likelihood take the yellow fever vaccine. As I nosied up the Amazon I wouldn't give two figs if the bloke sitting next to me had had the vaccine. I would expect protection to a certain extent regardless.
If I take the Covid vaccine I wouldn't give a rats ar$e whether the bloke next to me in the terminal had had it. Why should I? Isn't the whole point of taking this thing to get protection?
You blokes and blokettes who think everyone has to take it in order for it to work are seriously underwhelming me. What would be the point? In any event, I am thinking that way less than the 70% figure you are bandying about for the thing to work are going to front up for this emergency, less than 1 year old treatment that is not even vaccine by definition.
I would like to see you all overcome your fears and simply live with this until it passes.
