Pfizer stock jumps, Moderna, Merck tumble

Pfizer shares seeing best percentage gain since March of 2009.

Pfizer dialed up the vaccine wars on Friday after disclosing its oral pill for COVID-19 is 89% effective in preventing hospitalization. 

Shares are on track for the largest percent increase since March of 2009, as tracked by Dow Jones Market Group. Roughly $30 billion in market value has been created for the pharma maker just today on the promise of the treatment. 

Pfizer CEO Albert Bourla FOX Business' Neil Cavuto the medical tool is a "game-changer" for COVID-19 patients and should get fast approval. 

"I can't speak about how long FDA will take, but I can tell you that we will submit that before the end of the month, likely before Thanksgiving. Then it's up to them to give the approval. I suspect that they will do it quickly. So sometime in December, we will have already this year a few million pills" he detailed.
