If the Oxford trials go well (which I think they could; Boris Johnson has said he’s heard “promising things” from the trials at Oxford. I think we’ll know by next month, potentially July at the latest, whether it works from the efficacy results), then they’ve said they can produce a million doses by September and 100 million doses by the end of 2020, and that’s just with AstraZeneca; other companies around the world have signed up to manufacture it for their respective countries, so there should be a lot of doses by the end of 2020 if all goes well! That way, I could see a return to complete normality in early 2021, maybe mid 2021 at the latest.
