The difference is a matter of public health when people are dropping like flies from a novel disease. Extraordinarily events require extraordinary measures.
The best scientific and medical evidence at the time said distancing, masking and vaccinating were the best measures to reduce hospitalization and death. The same solid research said ivermectin, zinc, or other quack cures did not work and that the viral spread of this misinformation was leading to unnecessary deaths. Thousands of them. As well as overwhelming the hospitals.
The preponderance of evidence is that there is no link between Tylenol and autism. Nor is there an imminent public health emergency where people are dropping dead left and right. However, the administration is free to offer whatever bogus claim they wish. They do every day, anyway. But to prevent advertising of a tried and true product on questionable research is not alright. I’m sure Tylenol’s lawyers are working overtime right now, anyway.
