You refer to " application of triple antibiotic ointment (e.g. Neosporin and generics) into the nostrils" as an easy way of temporarily boosting innate immunity as if this was a well established fact.
I couldn't get an LLM to confirm this, but if I understood you correctly it sounds that is the current low-hanging fruit of not getting sick off my kids, could you explain that or suggest a link/ search term so I could clarify that to myself?
