A new US study found that the highest rates of so-called “vaccine hesitancy” (skepticism of or opposition to experimental COVID injections) is among those with PhDs.

The study reported a general drop from 46% to 35.2% “hesitancy” from January to May 2021 — but not among people with degrees and PhDs, who showed no change.
