This is a randomized placebo controlled, double-blind study, the most rigorous approach to testing vaccines and other drugs.
President Trump has said his goal is to bring at least one effective coronavirus vaccine to market quickly - potentially as soon as this fall.
One half of patients will receive a placebo, and the other half will receive two doses of the BNT162b2 vaccine spaced either three weeks apart or two months apart, said Dr. Steven Katzman, an internal medicine physician who is leading the trial in MI.
Already the United Kingdom has bought 100m doses of the vaccines, while the European Union has bought 300m. But another scenario could end with the United States hoarding doses and vaccinating more Americans, as they leave other countries out to dry. "The behavior of countries when it comes to vaccines in this pandemic will have political repercussions beyond public health".

In all participants, a T-cell response was induced, peaking by day 14, and maintained two months after injection. Phase III trial, BARDA also agreed to fund another trial created to evaluate the vaccine in children.
"By joining the facility at the same time that you do bilateral deals, you're actually betting on a larger number of vaccine candidates", Mariângela Simao, a World Health Organization assistant director general for drug and vaccine access, said at an August 17 briefing.
The Post reported that Health and Human Services Secretary Alex Azar and Deputy Secretary of State Stephen Biegun were "interested" in the initiative but were "ultimately overruled".
China and Russian Federation say they will start deploying vaccines before completing late-stage clinical trials, and US Food and Drug Administration Commissioner Dr. Stephen Hahn has said if the US gets enough data from advanced trials, it might be possible to authorize a vaccine before the trials are completed.
COVAX coordinators are in talks with China about whether it might also join, Berkley said. America alone is working fast on preparing the vaccine. According to health security experts, there are two problems with that strategy. This would leave the country vulnerable to imported cases of the virus and impact the USA economy harshly if the global economy has not recovered.
"We had a discussion yesterday with the (Chinese) government", Berkley said. "By joining the facility at the same time that you do bilateral deals, you are actually betting on a larger number of vaccine candidates", Mariangela Simao, a World Health Organization assistant director-general for drug and vaccine access, was quoted by The Washington Post, as saying at a briefing last month.
