Dr. Larry Palevsky: vaccination and germ paradigm

From Critical Thinking Episode 110 (September 01, 2022):
Dr. Larry Palevsky speaks on how he explains the vaccination paradigm to uninformed patients who are considering getting vaxxed...trillions of microbes yet vaccinated against a few.
"How do you explain the hundreds of trillions of other germs that you're exposed to that don't make you sick?"
"And isn't it possible that you are also exposed to the germs that we vaccinate against regardless of whether you're exposed to someone who's sick and nothing happens to you?"
