Skepticism, Science & Pseudoscience

I Googled silk vaccine and found a Scientific American article about it. I actually found several online articles about it. According to one article, the silk is spider silk.

Earlier today I posted a video in the DU Science forum about the production of spider silk that is being used by the medical profession, in which a spider silk gene is implanted into a goat embryo. This results in the adult goat producing milk containing the spider silk protein. When the fats are removed from the milk and the proteins purified, the silk strands can be spun onto spools. It's used to mend torn ligaments, and in other medical procedures too.

Your post was the first I'd heard of silk being used in vaccines. Very cool! Thanks for the info.
