Video: Stanford COVID-19 Vaccine Trial Enters Phase Three

New video shows the first injection as Stanford doctors start phase three of the Johnson and Johnson COVID-19 vaccine trial. This phase three trial will be done at 180 sites around the world with 60,000 participants, 1,000 of them at Stanford. It’s a double-blind study, meaning some will get active vaccine while others will get a placebo. They’ll all be monitored.
