In a nutshell, we showed that over-the-counter cheap generic antibiotic neomycin can be repurposed in nasal formulation to prevent & treat infection, block transmission, and reduce disease burden against a wide array of viruses. Since this is a host-directed strategy and virus-agnostic, it holds promise as a prophylactic strategy against any viral threat.
The advice in the screencapped thread was to apply a little with a q-tip to the inside of the nostrils.
There is no info on any dangers of doing this very often, but if you can’t avoid a high-risk environment it’s worth trying.
Here’s a thread about the study. https://threadreaderapp.com/thread/1782535781338222960.html

Honestly the risk of doing this occasionally (How often are you taking flights anyway? What are you Taylor Swift or something?) would almost certainly be lower than the risk of contracting covid even once, let alone for a subsequent time.
I’m not a doctor and this is not medical advice but… if you asked a covid specialist doctor which is worse for you - a full course of antibiotics or contracting covid, I know how they would answer. And applying a small amount of neosporin inside your nostrils is not nearly on the same level as a course of antibiotics.
I feel like it’s just a physical barrier. Like if you used Vaseline instead you would get the same result.
Those paper masks is only really effective on protecting others from you, not other way around.
