Today on FightBack! we discuss the latest information about the COVID 19 vaccine, and the new delivery systems that are being developed. We talk about this development and how the lessons learned with the COVID-19 pandemic are helping scientists gain ground on other vaccines. Joining us to shed light on these issues is Dr. Mike Ybarra, Emergency Room Physician and Chief Medical Officer at Pharmaceutical Researchers and Manufacturers of America who shares his knowledge regarding vaccine developments, not only regarding COVID, but other vaccines as well.
