In this video interview, Chief Medical Officer, Tal Zaks, M.D., Ph.D., explains Moderna's approach to use mRNA medicines to instruct a patient’s own cells to produce proteins that could prevent, treat, or cure disease. With little to no long term trials, is it a wise decision to automatically except covid-19 vaccines development with this new technology? Take notice that it is gene modification. Is the cure worse than the disease? It will take decades to find out. I have often wondered how the country with the best medical care can also have an increasing sick population in comparison to the rest of the world.
