Vaccines Won't Stop the Pandemic Unless at Least 50 Million Skeptical Americans Change Their Minds 

 

    For all the flak that President Trump has taken over the federal government's response, or lack thereof, to the coronavirus pandemic, the government's vaccine development project, Operation Warp Speed, looks like a winner. According to Pfizer, its vaccine prevented COVID in 95 percent of participants in its clinical trials, which are now complete. Moderna's vaccine, which got $1 billion in U.S. government support, prevents 94 percent of cases, the company said.

    It would be hard to exaggerate the degree to which experts have been surprised, and relieved, by these preliminary results. Early in the pandemic, conventional wisdom held that the best we could hope for was a slightly better hit rate than seasonal influenza vaccines, which in a good year protect 50 to 60 percent of those inoculated; the Food and Drug Administration set the target for COVID vaccines at a modest 50 percent. Now we have two vaccines that, in theory, are powerful enough to stop the pandemic in its tracks.

    […]

    To stop the pandemic, Dr. Anthony Fauci, the nation's top infectious disease official, estimates that at least three of four people would need to take a vaccine, preferably 85 percent.

    "If 50 percent of people don't take it, you still have a considerable public health challenge," Fauci said on the New York Times Deal Book webcast. Judging from the polls, getting to 75 percent would require convincing about 50 million vaccine-hesitant people to change their minds. "To say that's going to be a simple task is avoiding reality," he added. "This is going to be a difficult task."
