There will be no vaccine until Joe Biden negotiates a job for Hunter Biden as an executive with Pfizer (with a cut on the deal being laundered through Hunter for Joe).
And could explain why dems don't want the vaccine distributed until Biden is in charge. (Praying that is NEVER!)
Last I heard, amazingly, thanks to Donald John Trump, an actually effective and possibly safe vaccine already exists. It might be ready to go to the nursing homes on inauguration day.
