@futurebird I believe it plays into a bigger con going where people and even large businesses make money off of ignorance of disease and disorders. The "dietary supplement" loophole has allowed for a market that makes hundreds of billions a year in the US alone. There is a lot more profit in selling "Airborne" to people to prevent the flu than in them getting a flu shot and being careful (especially since "being careful" can mean going out less and spending less.)
