One of the hard things to talk about is the difference between: exposure, infection, disease, and infectivity. Headlines and news coverage of these has been almost universally terrible. There are rules of thumb thrown around like they are proven truth. The experiments to actually show at what time and how much infectious agent is produced are very difficult and as far as I know, none have been done. There are some studies on household spread, but to really know what's going on you need to do challenge trials - which means exposing people to the disease - which is highly unethical to do in humans - and challenge trials in animal models can be highly deceptive.

But generally speaking, yes, I expect to be exposed to Sars-Cov-2 many times in my life, and will probably be infected and may develop disease and infectivity. But as a vaccinated person, the period of disease and infectivity will be reduced.
