The thing is, if the virus evolves to spread better amoung vaccinated people, and the large majority of the members of a population have immunity from vaccination or infection, as is the case in South Africa, there is no evolutionary pressure that the virus becomes less lethal for unvaccinated and immunologically naive people.
It could as well become more lethal for them, or certain new age groups within the unvaccinated group, without that hindering spread among the other parts of the population.
In Denmark, 76% of the population has been vaccinated twice. 88% of the omicron infected are double or triple vaccinated. Just under 10% of the infected are not vaccinated. They are considering removing vaccination status from the coronapas (health passport) and requiring a negative test for a valid passport.
This is what I thought would happen, even without omicron.
Yesterday (16/12/2021) dr.dk, which is the public, "official" state broadcaster. They get their data from SSI (statens serum institut). I took a screenshot and notice today that they are showing numbers, not percentages.
It says (translated using DeepL, I don't speak Danish)
Omicron-infected persons by vaccination status:
Please note that these are raw numbers and do not take into account the number of people in each group. On 14 December, for example, 23.4% of the population had received the 3rd jab. This is only a statistic on infection, the figures say nothing about vaccine protection against serious disease. Data was collected up to 13 December.
So your initial comment doesn't really hold any more, as you seem to acknowledge yourself already. Right?
Um no, I was commenting specifically on Omicron infections and I am interested in the fact that the completely unvaccinated are undererepresented percentage-wise in Omicron infections.
I was not commenting on prevention of serious disease.
It could as well become more lethal for them, or certain new age groups within the unvaccinated group, without that hindering spread among the other parts of the population.
