I'm hopeful on that too, but I don't think it'll change the timeline all that much. Approval for the others is at least a month behind, maybe more in the case of Oxford due to increased scrutiny due to the clinical pause, and they all have a similar 2 dose schedule. Johnson and Johnson is the only one that's a single dose, and it just started their phase 3 trial last week. If you have multiple vaccines available it'll edge you forward to March, maybe? And that's assuming that they all are efficacious and get approved in early 2021.
