FormulaNova I'm having technical problems with the 'Quote' function so I'll reply like this;
"How do you know WHEN you are in the middle of a pandemic?"
Well it seems that most commentators refer to the current time as being in the middle of the pandemic so I guess I'm just going along with that narrative.
"I am not sure you understand the idea of vaccine resistant."
It's true I don't understand the topic with any authority at all. I've been listening to a few speakers on the subject including Geert Vanden Bossche who seems to put up a convincing argument. I'll link one of his videos below. The video is dated 1st June just for reference.
If I understand this guy's viewpoint, he is saying that because there are lots of vaccinated, they could hold a reservoir of the virus, and therefore result in a variant developing that would be more infectious or immune to the current vaccines at that time.
The problem with this logic is that he is ignoring that if a lot of people are vaccinated, there is not much virus circulating at all.
If the majority are vaccinated, there just are not enough cases to continually pass virus to the vaccinated. Reach high enough vaccination rates and there will be no virus transmission, except where you have small clusters of unvaccinated people where they can pass it amongst themselves.
Therefore, if you have a substantial level of unvaccinated WITH infection in the unvaccinated, you could get a problem.
The alternative? No vaccination, and let variants evolve in the survivors? Well, this lets a lot of people die and still results in the same problem he argues about. Clearly, if few people are unvaccinated, lots of people will catch the virus, and amongst the survivors, you could end up with the same problem of a more infectious version evolving.
We have seen this, and this is probably how Omicron evolved in southern Africa.
To clear up the question of virus immunity to (all) vaccination, in my understanding it cannot happen. A virus can evolve to be immune to the vaccination present in a person or population. It changes enough that the antibodies in your body do not recognise it as an invader straight away. This happens in "natural" immune systems where someone has had the virus before, the same as if they have had their immune system primed by a particular vaccine.
In order for this evolution to happen you need a large number of people with the virus, and if the majority are vaccinated, you don't have this.
If the virus evolves to a new type, you vaccinate against that type. If you still have a huge number of people that are unvaccinated, then this will continue to be a problem.
