lots of possibilities wrt "appropriate corrective actions", eh?

Mutations happen anyway, vaccine or no. They are random. They can confer different characteristics to the “life form” (if you can call viral DNA life.)

The difference between mutations in a vaccinated person vs an unvaccinated person is that in a vaccinated person, the virus is more easily defeated, so the only mutations that survive are those able to circumvent the vaccine. Therefore the virus evolves to be more difficult to defeat with a vaccine.

Some viruses survive in a vaccinated person, we know this because some vaccinated persons get sick. There may be fewer of them and fewer numbers of mutations but the mutations that do survive are those that strengthen the virus against the vaccine, hence why the vaccine is already becoming less effective against emergent variants.

My understanding about the replication incapable feature of some vaccines refers to the viral vector, not the mechanism by which it protects you. It renders the chimpanzee adenovirus vector incapable of replicating, not the covid virus. It defeats covid like the other vaccines, by notifying your immune system that the spike protein is foreign and to be attacked.

I disagree.  If a guy is having sex with a guy then he isn't straight, no matter what the reason.  He might have a preference for women, but having sex with men and women is bisexual by definition.  If you want to stretch it, you might say they are just morally ambivalent about who they have sex with, but they're still doing it with both sexes.

Anything else is leftist doublethink.  You are defined by the reality of your actions, not by how you identify.
