Ultrasound can push vaccines into the body without needles (www.newscientist.com)

Vaccines can be delivered through the skin using ultrasound. This method doesn’t damage the skin and eliminates the need for painful needles. To create a needle-free vaccine, Darcy Dunn-Lawless at the University of Oxford and his colleagues mixed vaccine molecules with tiny, cup-shaped proteins. They then applied liquid mixture to the skin of mice and exposed it to ultrasound – like that used for sonograms – for about a minute and a half.

Sitting for a minute and a half, not including prep and cleanup, or just getting stabbed a little. shrug

Edit: To save the next half dozen people exclaiming "needles!" the trouble. I would refine my point to, "great to have the option but I imagine it as being more of a fallback than the beginning of a new era".

Maybe one way of looking at it might be : this would be safe enough you could trust people to self-administer, and you could therefore take the professional with the needle out of the equation.

90 seconds of one person's time has got to be better than the quick jab by two people, no?

I don't think any amount of de-specializing would be enough to trust the ignorant and/or malicious masses could or would self-administer adequately.

You're right. Can't just post them to folks and expect 100% uptake. It might widen the possibilities of more people getting more vaccines, though. In my books, this can only be a good thing.
