“None doses” is the correct answer, if you’ve had covid.
T cell immunity is long lasting.
No population on earth ever had more than 20% symptomatic infection, that I can find.
Even the floating petri dish, Covid Princess, never had 20% get covid.
Why?
The only explanation I see is that there is long lasting T cell immunity in a large percent of the population.
Being exposed allows these people to update or “perfect” their immunity - the majority never knowing they were exposed. This is how herd immunity is built.
Well, up until a few minutes ago, that would have the baseline assumption. If someone has suffered the disease and recovered, there would be no need for a vaccine for that disease.
There are exceptions, of course. Things like tetanus need a booster every few years, and if you had chickenpox as a child you might want to consider the shingles vaccine in your later years.
But the idea that you should be vaccinated for a disease you just beat a few months ago is brand spanking new. A serious investigation of why that is would be in order, if we had any real journalists left in the world.
