That is a long ways from “almost no chance!”. You are not 100% immune to the virus.
Also, we can still be infected. We can carry the virus in our bodies and pass it on to others even if we aren’t making more of it. That’s why we still need to be careful.

The bolded part is wrong. The virus cannot duplicate itself. Your body duplicates the virus because the virus programmed it to do so. The virus can get into you, this is true. The speed of the immune response effects what happens next. In 95% of the vaccinated, your immune system sees it, and destroys it before it can get a foothold.
In the other 5%, the immune response is attenuated. It can go from allowing very little of the body's cells from getting infected to having no effect at all. It is clear that the vaccine is stimulating _some_ response in everyone who has had it. At least to the spike proteins that the vaccine is targeted towards. As to mutations, time will tell, that said, one of the more stable sequence motifs is the spike proteins. I.e. if the spike protein changes much, the virus doesn't work any longer, therefore since this is where the vaccine is targeted, it will likely have good efficacy even in mutations.
