That's pretty awesome. so we are resistant to pneumonia? it did I misread?

PG (but not VG) is a germicide and virucide. There are indications that it could be used as an aerosol disinfectant similar to Lister's first methods. In this respect it could be beneficial in case of pneumonia etc.
However if large quantities are inhaled then other results might obtain. In particular, if a serious lung disease such as emphysema is already present, it would not be prudent to think large quantities of anything other than plain air could be beneficial.

Unless I misread, they're talking about eliminating airborne infection vectors, which wouldn't make you "resistant", but would reduce the spread of airborne diseases in a treated air space, such as a room.
Makes sense. Airborne bacteria is distributed in water particles and PG is hygroscopic. So the same thing that dehydrates you when you vape would also tend to clean infected water particles out of a room's air.
So when someone objects to you vaping indoors, you can tell 'em you're disinfecting the room.
(You'd be hard pressed to substantiate it, based only on a 1942 preliminary "indication" in a non-technical publication, but you could still tell 'em that.
)Here's a more technical PDF at NIH from the same era: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2135685/pdf/729.pdf
From Wiki:
"Although glycols are effective air disinfectants in controlled laboratory environments, it is more difficult to use them effectively in real-world environments because the disinfection of air is sensitive to continuous action." (Additional citations in footnotes)
Disinfectant - Wikipedia, the free encyclopedia
If the report is true, you'd expect a statistical record of lower instance of disease spread (between co-workers) in a theatrical setting or "haunted house" fun house, where fog machines spread PG vapor all the time.
(Perhaps offset in a theater setting by the stage kissing.
)(Although there's the old story about the actor who would always kiss his *own* hand.
)Links at the NVC's web site seem to indicate a number of commercial disinfectant sprays which use PG (among other things).
Interesting...might explain why I haven't been continually sick since the start of the school year...I tend to catch every illness. Could be coincidence, but if not I am very happy about it! Thanks for sharing this article!
I just started vaping 2 weeks ago and love it. I quit tobacco last feb. but kept falling off the wagon. I think vaping is what I've been looking for, but I have some concerns about long term inhalation of PG. The msds sheets on the stuff makes me thing vg is a better alturitive. PG is an irritant and causes centural nervous system damage in large enough quantities. It also can cause liver and kidney damage. Like I said, I am very new to vaping, and am very exited about finding something that fullfills my craving for a habit, hopefully without killing me, but I am concerned about the long term effects of inhailing PG, PEG, and the thousand of flavorings that are available. I am reading everything I can find to educate myself, but this is a relitively new thing and there doesn't seem to be much research out there that would be relivant to vaping. I have not seen any long term studies done where people inhailed PG vapor all day for 20 years. Not to mention mixing it with flovorings. I know it is safer than cigarettes, but I would like to continue vaping with better understanding of how it reacts with human lungs at normal vaping concentration and at what level of concentration it would cause damage. Anyone that can help with these questions would be greatly appreciated.
PS....I don't think studies on PG inhalation from the 1940's is gonna do it for me. These people thought smoking tobacco was good for you. The technology was ....Frankenstien Laboritory Middleages like. How bout something from say the year 2000 and up.
Vaping is way too new for the research you speak of to have been done. I myself have vaped for two and a half years, and I think the longest term vaper would only have been vaping for coming up to 4 years. So until tests are done, its going to be long time before we know anything positive or negative.
We are our own guinea pigs, for this research. Hence its important to consult your doctor if you have any symptoms of illness, not to point the finger at vaping, but to eliminate vaping as the cause.
MSDS sheets tend to look at inhalation from an emergency point of view, so as to be useful to fire services for spillage and of course fires, explosions etc., so can be of little help to us.
Flavourings at this time are the main concern.
PG does without doubt act as a germicide/virucide, hospitals used it for years, and since I started to vape, I have only had one cold, and not the countless ones I suffered lifelong, not to mention the yearly Bronchitis, which has plagued me since childhood.
VG was used in cough syrups, as it can cause us to cough thus bring up phlegm, however, if you note, Glycerin can be produced by the human body itself, although the glycerin produced from vegetables seems to be more popular with vapers, than the type produced from animals.
But still not enough is known about either of these substances when inhaled on a daily basis. Only time will tell Im afraid.
In the meantime, I for one, am happy to continue with my personal experiment, and enjoy being a guinea pig...

Yes PG is cool.. this article contains an abundance of similar studies...
