Every time we see or hear an expert on the topic of COVID-19 vaccines, she/he is either circumspect to the point of pessimism (this is rare, but see e.g. Robert Gallo) or obviously trapped in a spiral of wishful thinking (this is common). We've never made anything like this hypothetical drug. Forget about election day. I'll be surprised if we have a commonly-available and effective COVID vaccine in 2021.
