Pfizer vaccine will make ‘an enormous difference in pandemic,’ doctor says


Dr. Ashish Jha, dean of Brown University’s School of Public Health, tells TODAY that the Pfizer’s announcement that its coronavirus vaccine candidate is now about 95 percent effective is “great news … it’s going to make an enormous difference in the pandemic.” He adds: “The challenge now will be getting these vaccines out quickly and effectively.” But he warns the pandemic “is really out of control” and urges people to hold off on holiday celebrations.
