Now almost all of them have natural immunity.
Well that is a fascinating subject, not just there but everywhere. There are a ton of people there that I am sure had it and never got tested or went to a hospital. There is a strong go to hospital and die feeling locally.
I think natural immunity is a thing, but I am not sure if or how it gets tested to see just how good it is. They did prove it longer lasting than they thought recently, but how 'good' is it? IDK.
And then what is the system to 'prove' it? Do they set up testing and hand out antibody cards? IDK.
I think most Gov, MX included will stay with pushing vaccination, as its good for those without it prior infection and not harmful to those that had covid and possible even helpful to long haulers.
And if the vaccination deny the disease enough hosts and crush it to the point no one cares, end of program. I would be surprise we ever get to natural immunity cards.
But I cannot see the island that won't yell at tourists or enforce the 50% in restaurants is gonna start enforcing a vax card check.
