Oh, don’t worry, Dugway, GasBag, and the rest are still here, posting their propaganda as relentlessly as the tide hitting the rocky shore.

No. Most of us trained in formal logic and scientific thought at some point after repeated testing arrive and the axiom, never argue with an idiot for they will reduce you to their level and defeat you with their experience. Such is the nature of those who have created a religion around antivaxx. You tend to repeat the same things and then take a victory lap because the increasingly bizarre nature of what you have to twist yourself into defies not only the imagination but is beyond logic or rational thought.
