Not to get us too far off topic here, but I wanted to jump in with a word of caution regarding this product. As a scientist, I always want to promote scientific critical analysis and rigor when examining claims, particularly from companies that are selling products. While the platform of a nasal mist seems promising, the claims that this product make appear to be based off of one or two papers, written by the creators of the product and others associated with the company (a major conflict of interest), and the paper is not published in a recognizable, reputable journal. In addition, the data from the paper by the creators is fairly limited and their data suggest that the products limits
exhalation of droplets, meaning that it could be good for slowing COVID if everyone else exhaled fewer particles (or would limit the spread of COVID if your child already had COVID), but there does not appear to have any empirical evidence that the product would directly lower risk of COVID for anyone using the product (short of a large percentage of people at Disney using the product).
Thus, I would caution against any one of us from viewing this as a way to directly protect our children at
Disneyland. There does not appear to be any credible scientific data or consensus yet that this product provides any protection against COVID unless the majority of visitors were using this, and I would hate for any parents or children to relax their precautions and use of other non-clinical interventions (mask wearing, hand washing, etc.) while at Disneyland due to the impact of using this product.
Have a great and safe time with your families at DLR!
