“A simple nasal wash with a saline solution performed within 24 hours of symptoms done twice daily for 14 days can reduce the risk of being hospitalized for COVID by 8X.  This is much better than Paxlovid (only a 2.5X reduction if you believe the trial data).  This is much better than any COVID vaccine performs in practice and it’s much safer too.”
