If and when a coronavirus vaccine is developed, 'The chances of it being 98% [effective] are not great,' Dr. Anthony Fauci says. Here's what that means.
Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases for the last three decades and an expert on pandemics for the last four decades, has been optimistic on a vaccine arriving at the end of 2020 or in early 2021, but he has also cautioned the public on their expectations for the effectiveness of any vaccine that is developed.
“ ‘The chances of it being 98% are not great. Which means you must never abandon the public-health approach.’ ” Fauci advocates face masks, social distancing and avoiding bars and indoor spaces with crowds. “If we do those things — and I’m going to repeat it until I’m exhausted — those things work,” he said on Friday’s live stream. “When you have something that needs everybody pulling at the same time, if you have one weak link in there that doesn’t do it, it doesn’t allow you to get to the end game.”

Here’s how many lives could be saved if everyone wore a mask — starting today “None of those seem to be operational at present,” Gregory Poland, who studies the immunogenetics of vaccines at the Mayo Clinic, told MarketWatch in April. “With influenza, you need herd immunity of 60% to 70%. With measles, you need about 95%. With COVID-19, it’s somewhere in the middle,” he said.

America’s COVID-19 death toll in the U.S. could reach nearly 300,000 by Dec. 1, but consistent mask-wearing beginning today could save approximately 70,000 lives, according to projections released last week from the Institute for Health Metrics and Evaluation at the University of Washington’s School of Medicine.
