“There are more than 70 COVID-19 vaccine efforts globally, at least; with so many, it’s reasonable to be optimistic that we will have a vaccine in somekind of record time frame. There are even a few that are posed to break the record: one from a company called Moderna that began trials in humans in March (this is the one that Fauci is referring to in his estimates), one from a group at Oxford that claims it could even have doses available by fall. Yes, it says it might even have some doses by the fall.”
“”The thing to note with the timeline is people often caveat it with a statement, ‘if everything goes perfectly,’ ” says Matthew Watson, an analyst at the Johns Hopkins Center for Health Security. “I think that’s really important to pay attention to. Things rarely go perfectly.””
Medicynical note: it’s an unprecedented effort but a lot can go wrong.
