Microneedle patches have been under development for decades.  But the breakthrough on this revolutionary new patch came from 3D printing the microneedles on a polymer patch just long enough to reach the skin and deliver the vaccine. Customization Through 3D Printing The key to the new patch is 3D printing which enables customization of the microneedles for various vaccine patches. The researchers

Vaccines Coming By Flying Drones Zipline is a 7 year old startup, headquartered in San Francisco.  It just disclosed that it is developing a COVID vaccine drone delivery system with a COVID vaccine manufacturer.  Zipline did not name the manufacturer that it's working with.  The delivery process is very complicated because many of the vaccines like those from Pfizer and Moderna need to be kept at cold temperatures or they de-nature. April Takeoffs Zipline says it will have "end to end" cold chain capabilities" in p
