vaccinated people will go up, but it is not a pleasant one to think about.
As unvaccinated people die, the vaccinated survivors will become the majority. It's what happened in nature before vaccines.
I came across an interesting study online of the DNA in a village in England where the survival rate from the Plague was known to be higher than other villages. This was a couple months ago and I didn't save a link.
The study found a genetic mutation in descendants of people who lived during the Plague. This mutation allows the human immune system to avoid Plague infection or to recover if infected. By tracing the records of Plague era villagers and their descendants through waves of the Plague into modern times, they learned that inheriting two copies of the mutation gave immunity. Inheriting one copy allowed people to survive if they did get infected. The survivors passed the mutation to descendants until there was inherited immunity in the village.
The study then tested other European populations for the mutation, especially in areas known to have been hit hard by the Plague. They found the mutation in high numbers among today's descendants. People without it had died off over repeated waves of Plague. Eventually, there were enough mutations in the general population to stop the waves of Plague from recurring.
We know now that the people today who are asymptomatic carriers of covid have a Neanderthal gene mutation that protects them. There is another Neanderthal gene mutation that makes people more susceptible to covid infection. If there were no vaccines, those mutations would determine who survives to give future populations immunity to covid.
We could also defeat covid more quickly, with less suffering and death, through vaccines. But, given human behavior, it looks like nature will play a big part in who survives.
