If it's McDonalds giving that advice to customers, it's considered practicing medicine without a license. It's considered an end run around the government regulations regarding drug advertising.

Maybe McDonalds should just print this graph on their coffee cups. It shows daily deaths from Covid-19 in the US from January 2020 until today. That big peak? It happened in January, 2021. The downslope started just about the time that vaccines started becoming available. Coincidence? Apparently to the anti-vaxers.
