Vaccines don't eliminate all risk but they do reduce it.
Yes expect that this covid vaccine isn’t a proper vaccine is it?
It doesn’t and never will make covid disappeared unlike, polio, measles etc….
It doesn’t last very long. 10 weeks they are telling us and then the protection drops considerably. Unlike the flu, we would need some booster at least every 3 months.
As we have learnt, variant can sweep over the world very quickly. And the vaccine might well be totally inappropriate.
Eg for omicron we don’t know yet if the two doses of the vaccine actually have any impact of the transmission of the disease. We do know that the vaccine efficacy with AZ is about … ZERO (so I imagine that it has no effect too on avoiding the spread)
This is not a vaccine. It’s a prophylactic drug that protects people for about 2~3 months.
I am not aware of any prophylactic drug that doctors and HCP have to take before treating people.
