Traditionally, when someone says “vaccine”, the image of a syringe and needle usually springs to mind. But injections need trained staff to administer them, and they’re unpleasant, even for people who are not scared of needles. So vaccines you can inhale sound altogether more attractive. And that’s what researchers at Rutgers University in the US have been working on. They’ve found a particular clutch of chemical compounds that are very good at passing harmlessly through the lungs and entering the bloodstream where they can interact with the immune system. What’s exciting is that these chemicals can be coupled up to drug or vaccine molecules and used to pull them into the circulation too. Renata Pasqualini told Chris Smith how it works…


Firstly thanks to Chris for forwarding this onto me, second - wouldn't;t it be better if you could simply breath in such using a gas or some sort of compound that would fill a room or large area - that simply was breathed in by the person(s) - sound sci-fi but would make vaccination of mass numbers much quicker - I do admit several considerations would need to be addressed, allergic reaction -effect amounts - etc, but in a fight against a fast moving viral infection that could at any point itself become completely airborne then something like this in the arsenal or weapons cabinet against it could provide a quicker delivery method for huge numbers - just a thought and am sure as Chris has said it would've been thought about - but has it been thought of in that context, rather than single administration - as such could be used in Ari-con in large buildings etc, the advantage also would be the coverage of larger areas and several people all at once..
