Pfizer s Covid-19 Vaccine Proves 90% Effective in Latest Trials – WSJ

By Thomas A. Smith

A vaccine developed by Pfizer Inc. PFE 7.69% and partner BioNTech SE BNTX 13.91% proved better than expected at protecting people from Covid-19 in a pivotal study, a milestone in the hunt for shots that can stop the global pandemic.

The vaccine proved to be more than 90% effective in the first 94 subjects who were infected by the new coronavirus and developed at least one symptom, the companies said Monday.

The positive, though incomplete, results bring the vaccine a big step closer to getting cleared for widespread use.

Pfizer said it is on track to ask health regulators for permission to sell the shot before the end of this month, if pending data indicate the vaccine is safe.
