About 22% of americans identify as antivaxxers, and about 13% Master's and/or doctorate and/or professional degree. For your claim to be true, over 90% of people with advanced degrees would have to identify as antivaxxers.

That is, if words mean things to you. If what you intended was "I feel like anti-vaxxers are smart, and want to come up with a fancy fact-like way of saying that," then you're spot on. good job sport.
