In your conspiracy theory, surely, they'd just have announced after polls closed? Why wait for it to be called? Also, this vaccine was actually developed by a German company, who would likely resent their partner playing this game.

This timing is consistent with when we've been told we might see early results all along, really; it shouldn't be that surprising. Expect announcements from other teams over the next couple of months.

First business day after the election was called, but not after the election itself (i.e. people couldn't vote after 11/02). Or are you saying that they were planning on not releasing this at all in case of a Trump win and not just trying to influence the election?

The thought didn't even cross my mind that they'd hold the vaccine for political reasons. Just the press release. Holding the vaccine itself for political reasons would be murder on a mass scale.
