That Trump's administration is pushing these pharmaceuticals for a miracle cure before the election. Astrazeneca had a serious side effect in the UK, and their trials have been paused in the US. Pfizer said their trials have resulted in mild to moderate side effects and they're looking to add more trial candidates with stable HIV, Hep B, and Hep C... so it seems like they might be having problems with people who have immunodeficiency. I really hope our government isn't stupid enough to try and ramrod a vaccine that's not ready. I wonder how the antivaxxers of the world are going to respond to this?
