Yes, almost no one who is fully vaccinated ever died from COVID. But those who underwent a real COVID rarely ever reinfected again, set aside suffering even mild symptoms. There are literally lower thousands reinfection cases in the world (0.5% by PCR research in Denmark), while infection cases among fully vaccinated are ordinary, especially with Delta variant.
> Or they will serve as a mutation vector for the next, more transmissible, deadlier variant.
Unfortunately, hosts with partial immunity (natural asymptomatic cases or half-vaccinated) are more suitable environment for virus mutation. In tabula rasa host virus just takes over the system by storm, all mutations are in equal conditions. Weak immunity means new mutations are having an advantage and natural selection completes the case.
And now we know that even fully vaccinated people are relatively easily contracting Delta variant. You may draw the conclusion.
