The US drug company Pfizer Inc says its experimental COVID-19 vaccine, developed with German firm BioNTech SE, is more than 90 percent effective in late-stage trials.
The news comes as 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 BioNTech SE are the first drugmakers to release successful data from a large-scale clinical trial of a COVID-19 vaccine.
More than a billion doses could be administered next year.
BioNTech SE admitted they are still waiting on more results to further prove its safety.
