I am not anything, but a doc during am outdoor first aid cert course insisted that the real benefit of Neosporin was that it was petroleum jelly and it created a hydrophobic/biologically inert barrier over cleaned/irrigated membranes and wounds (blocking vectors of infection), and that every bug was already resistant to its antibiotic mix and had been for decades.

I did take a bunch of biology and microbio and he made a very convincing case for using petroleum jelly on nicks, cuts, etc.

but I am, again, not any sort of human health professional.

Also, just wear an N95 mask. But I see no reason not to do both.

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.

is this not the antibiotic abuse that we've been warned about since forever? Not using antibiotics when there isn't an open wound, or a microbial infection?

I mean, neosporin isn't prescribed, but still.

Seems to me like actual anti-virals like iota-carrageenan (Betadine brand) nasal spray would be more effective...

The incidence of COVID-19 differs significantly between subjects receiving the nasal spray with I-C (2 of 196 [1.0%]) and those receiving placebo (10 of 198 [5.0%]). Relative risk reduction: 79.8% (95% CI 5.3 to 95.4; p=0.03). Absolute risk reduction: 4% (95% CI 0.6 to 7.4).

Iota-Carrageenan patients reported a mean blocked nose score of 0.42, corresponding to a reduction of approximately 50% (Figure 3). Further post hoc analysis of this symptom revealed that 71.4% of Iota-Carrageenan patients did not report the symptom blocked nose at the end of the study. In the placebo group only 36.4% of subjects were free of this symptom.

viral load in the placebo group increased almost 6- fold (579%), while it dramatically decreased by 92% in the Iota-Carrageenan group (p < 0.009).

A concern I have about this is the long term effect on the nasal microbiome. In the same way that using antibiotics orally can fuck up your gut microbiome and lead to an increased risk of other health problems, could fucking up the nasal microbiome lead to poorer viral resistance in the long term, or an increased chance of developing allergy/histamine/MCAS issues (which are already triggered by COVID infections)?

a lot cheaper than covixyl ...

Every flight huh? Watch the feds start putting the bioweapon in the ice and biscoff cookies now that we’re onto them.

Hmm I have used either that stuff or petroleum jelly in my nose in the winter at peak flu times because the cold winter air gives me nosebleeds and it's a good remedy for a dry sinus. Perhaps I reaped another benefit without knowing.

I'm flying on Sunday, so I'll give this a try.

Honestly, I immediately assumed this is fake as hell but I hope it works!

If I chugged bleach, I can sniff cream.
