Pfizer Inc said on Friday it could file in late November for U.S. authorization of the COVID-19 vaccine it is developing, suggesting that a vaccine could potentially be available in the United States by the end of the year.
That timeline makes it unlikely, however, that a vaccine will be available before the U.S. election, as President Donald Trump has promised. Pfizer, which is developing the vaccine with German partner BioNTech <22UAy.F>, said that it may confirm if the vaccine is effective as soon as this month but that it also needs safety data from a 44,000-person clinical trial that will not be available until next month.
The Pfizer news, published in a letter from its chief executive on its website, lifted the U.S. stock market and the company's shares. Shares fell slightly of rival vaccine maker Moderna Inc , which is close to Pfizer in its vaccine development.
