Preclinical studies suggest a drug-free nasal spray could ward off respiratory infections
www.eurekalert.org
A new study details how a nasal spray formulated by investigators from Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, may work to protect against viral and bacterial respiratory infections

The spray is called "Pathogen Capture and Neutralizing Spray" (PCANS) for now

This data suggest PCANS as a promising daily-use prophylactic against respiratory infections.

The study is paywalled, and the abstract doesn't list its ingredients beyond

The formulation consists of excipients identified from the FDA's Inactive Ingredient Database and Generally Recognized as Safe list to maximize efficacy for each step in the multi-modal approach.

Based on that description, its ingredients might not be very different from Covixyl, though it claims to be much more effective.

Edit: Apparently its already for sale, I included some details in a comment

    Coming in with the anecdotes, but I've done a public facing job with often just the carrageenan spray as prevention in small unventilated spaces face to face with clients for 6 months now and never got sick from work.

    I did get covid, but from family via my partner at home.

    The last time I had to spend an hour with a visibly sick person was at the start of this week and so far so good. Might be immunity too from having just had covid a little over a month ago though. I wish masking was ok in my work, but it's not.

    But considering how high risk my work is and how all my co-workers sure are sick all the time and I'm not, it makes me think the spray might at least be helping. I also avoid gatherings and have an air purifier on my desk, I also don't people on my freetime. So there are many reasons for this as well.
