Bioengineer Michael Fischbach studies alternative vaccine delivery methods, like self-administered creams with no needles, health professionals, or side effects. He teases a day when vaccines that don’t make you feel bad come in the mail in ketchup-style packets. Such innovations would greatly improve vaccine uptake, especially in developing countries, and speed global response to novel viruses. It would change how we think about vaccines, Fischbach tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.
