Harvard Medicine has developed a simple, drug free, and highly effective prophylactic measure against respiratory infections such as pneumonia, influenza, and COVID-19. Referred to as a 'Pathogen Capture and Neutralizing Spray', or PCANS, this spray coats the nasal cavity for up to eight hours and acts as a physical barrier that neutralizes a variety of viruses and bacteria with more than 99.99% effectiveness.
Though it sounds promising and novel, it does not serve as a substitution for vaccines-- only as an additional layer of protection. It is worth noting that the study of its effectiveness came from a clinical trial tested on mice. The effectiveness of the spray may vary in a real-world environment. It is currently on the market under the name 'Profi' and retails for around $20, but human clinical trials have not yet been publicly released and the product has not been FDA approved. Still, this cheap, safe, and convenient spray may serve as an additional layer of protection against common infections.

This is so interesting. I am curious how this is doing currently in the drug stores. I have seen similar things to these, though I am unsure if they are qualified to be the same. As a fan of shark tank as well, I am curious of how much it cost to make this medicine versus how much they are selling it for, especially since it has only been tested on mice.
