Doctor Robert Murphy is the Professor of Infectious Diseases at the Northwestern Feinberg School of Medicine. Dr. Murphy talks about the 72% efficacy rate of the Johnson & Johnson vaccine compared to the higher efficacy rates of the Pfizer and Moderna vaccines.

Dr. Murphy also talks about why pharmaceutical companies don’t all produce the same vaccine.
