Pfizer and BioNTech say their COVID-19 vaccine is over 90% effective

(Reuters) – Pfizer Inc said on Monday its experimental COVID-19 vaccine was more than 90% effective, a major victory in the fight against a pandemic that has killed more than a million people, battered the world’s economy and upended daily life.

Pfizer and German partner BioNTech SE are the first drugmakers to release successful data from a large-scale clinical trial of a coronavirus vaccine. The companies said they have so far found no serious safety concerns and expect to seek U.S. authorization this month for emergency use of the vaccine.

If authorized, the number of doses will initially be limited and many questions remain, including how long the vaccine will provide protection. However, the news provides hope that other COVID-19 vaccines in development may also prove effective.

“Today is a great day for science and humanity,” Albert Bourla, Pfizer’s chairman and chief executive, said.

“We are reaching this critical milestone in our vaccine development program at a time when the world needs it most with infection rates setting new records, hospitals nearing over-capacity and economies struggling to reopen.”
