When did Michelle Malkin turn into an anti-vax nut? Has she always been on that horse?
Fine, apparently it works on mice! How long will it take to test on humans? How many deaths happen while they continue to test? Why not use FDA approved existing drugs? They are obviously safe and they are available! Why wait?
The researchers also used a novel approach to deliver the drug, called a microneedle array, to increase potency. This array is a fingertip-sized patch of 400 tiny needles that delivers the spike protein pieces into the skin, where the immune reaction is strongest. The patch goes on like a Band-Aid and then the needles—which are made entirely of sugar and the protein pieces—simply dissolve into the skin.
“We developed this to build on the original scratch method used to deliver the smallpox vaccine to the skin, but as a high-tech version that is more efficient and reproducible patient to patient,” Falo said. “And it’s actually pretty painless—it feels kind of like Velcro.”
The system also is highly scalable. The protein pieces are manufactured by a “cell factory”—layers upon layers of cultured cells engineered to express the SARS-CoV-2 spike protein—that can be stacked further to multiply yield. Purifying the protein also can be done at industrial scale. Mass-producing the microneedle array involves spinning down the protein-sugar mixture into a mold using a centrifuge. Once manufactured, the vaccine can sit at room temperature until it’s needed, eliminating the need for refrigeration during transport or storage.

At least I learned some neat stuff today.
Why would people want to vaccinate against Covid 1-2 years from now?
Would this be vaccine like they currently have for seasonal flu strains?
Sometimes they work at keeping you from catching the bug, sometimes they lessen the effects if you do get the flu, sometimes they do nothing at all and some have said after a flu shot the later on had the worse case of the flu ever.
Or is it more like a polio vaccine when after several vaccinations, one can become 100% immune? And is it just for this specific strain of SARS-CoV-2? So many questions,so little answers.
