the idea of using povidone-iodine as a nasal prophylactic is interesting, but I think your explanation is lazy. for one, it's hard enough to get people to wear masks, much less snorting cleaner every morning! second, if this works, why wouldn't doctors and nurses be using it? they were at tons of risk before the vaccines. edit: less sketchy link to a study of Iota-Carrageenan nasal spray for covid prophylaxis: https://www.medrxiv.org/content/10.1101/2021.04.13.21255409v1 https://www.medrxiv.org/content/10.1101/2021.04.13.21255409v... not peer reviewed, but a registered clinical trial reporting positive results.
