There are many promising late-stage trials of stem cell therapies that reverse damage from COVID-associated acute respiratory distress syndrome (this is the killer). These are far more advanced than any vaccine candidates.

Vaccines are highly likely to work given the wide range of methods in over 220 trials. We have vaccines with a known safe dose in P2 studies which do produce antibodies. That is close. The question is when.....
