More than 1.6 million Americans have been infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and more than 10 times that number carry antibodies to it.

The current COVID-19 pandemic is one of the most devastating events in recent history. The virus causes relatively minor damage to young, healthy populations, imposing life-threatening danger to the elderly and people with diseases of chronic inflammation. Therefore, if we could reduce the risk for vulnerable populations, it would make the COVID-19 pandemic more similar to other typical outbreaks.
