Scientists are suggesting that it will be somewhat less effective at preventing transmission and asymptomatic infection than it is at preventing symptomatic infection. From the New York Times: “Preventing severe disease is easiest, preventing mild disease is harder, and preventing all infections is the hardest,” said Deepta Bhattacharya, an immunologist at the University of Arizona. “If it’s 95 percent effective at preventing symptomatic disease, it’s going to be something less than that in preventing all infections, for sure.” Still, he and other experts said they were optimistic that the vaccines would suppress the virus enough even in the nose and throat to prevent immunized people from spreading it to others. https://www.nytimes.com/2020/12/08/health/covid-vaccine-mask.html https://www.nytimes.com/2020/12/08/health/covid-vaccine-mask...
