KEY POINTS
  • Pfizer's Chief Executive Officer Albert Bourla noted in a letter posted on its website that the filing depended on several factors, including data on effectiveness that may or may not be available by late October.
  • A filing for emergency use authorization with the U.S. Food and Drug Administration could come 'soon after' that data is ready, Bourla said.
  • The U.S. Food and Drug Administration has said it wants at least two months of safety data before authorizing emergency use of any experimental coronavirus vaccine.

Pfizer said on Friday it may file for authorization of the Covid-19 vaccine it is developing with German partner BioNTech in late November, making it unlikely a vaccine will be available before U.S. elections as President Donald Trump has promised.

The regulatory filing for the vaccine could come as soon as safety data is available, possibly in the third week of November, Pfizer said, lifting the company's shares and the broader U.S. stock market.
