Got his response. He is an Oncologist at Texas Oncology. His remarks are in this context:
1) He's probably too busy to read the entire study but he may have. I would think he should have read it because he is in the business of advising cancer patients whether or not to get a vaccine (and boosters) along with wearing a mask. Basically, he thinks I should do both.
2) I am immunocompromised so his comments were directed to me and probably not for otherwise healthy people.
