I am extremely skeptical of the ability of public messaging to disaggregate "the J&J vaccine is under review as a precaution" from "the J&J vaccine is not safe and the others may not be either" in the minds of normal people. An incredibly crucial, high-stakes test for the press.
Tune in to Fox News tonight when Tucker Carlson interviews Alex Berenson about how they were right all along, the government and the media were lying about the vaccines which are not safe.
All of which is to say that I am not a public health expert but this seems like a pretty massive risk to take over a one-in-a-million risk against a virus with a U.S. body count of more than 550,000.
