After listening to it, I wonder if he's under the impression that vaccines are permanent, as in lasting the rest of your life (?)
Although this is true (Or nearly so) for some diseases, it's not for others. Tetanus, for example, requires regular boosters because immunity fades after just a few years.
At any rate, it's much better to take your political information from political sources and your medical information from medical sources.
This is the same guy that said back in February, "...I’m dead right on this. The coronavirus is the common cold, folks," which is true for some strains, but not for the one responsible for Covid-19 which is a novel strain.
Two months later, the U.S. has 23,644 dead out of only 587,173 confirmed cases, which is an alarming ratio.
