Or, that's not at all how immunology works or how the recent giant outbreak went.
Because it was nearly eradicated due to previously high vaccination rates, no one recognizes the actual symptoms anymore. period....your post exemplifies that incomprehension and is exactly how the most recent outbreak ended up spreading at Disney to nearly 200 people across 24 states.
Regardless of whether one is vaccinated or not, you can become infected and not show any visible symptoms for 8-10 days. You can infect others up to 4 days before the tell tale rash appears. Before then it merely presents as the common cold. This is exactly why it's so insanely contagious.
Unless you're going to quarantine your child for every single minor cold, no, you absolutely cannot prevent transmission to others just by seeing the rash.
Those vaccinated can contract measles but will typically not become as ill. Less coughing equates to less spreading. So no, those vaccinated are definitely not more of a risk to the general population than the unvaccinated are.
