ZocDoc Inc. founder Cyrus Massoumi has been frustrated by the imbalance in U.S. vaccine supply and demand -- with providers tossing out doses they can’t use, even as many people desperately seek shots.

So the former CEO of the doctor appointment-booking company has quietly launched an online platform to match providers with those willing to be on standby for Covid-19 vaccines. More than 200 sites in 30 states are being connected through the platform, called Dr. B, with half a million Americans requesting to be notified when doses become available nearby. And that number continues to grow.
