BioNTech and Pfizer Hope to Have Late-Stage Coronavirus Vaccine Results by October

On Tuesday, BioNTech (NASDAQ: BNTX) confirmed what its big pharma partner, Pfizer (NYSE: PFE), had already let out of the bag: The companies hope to have phase 3 results for their coronavirus vaccine candidate by October. Once the clinical trial is fully enrolled and all of the approximately 30,000 subjects have received the vaccine and placebo, it'll take another 21 days before the subjects will get their booster shots. It isn't clear, for instance, if BioNTech and Pfizer think they need data from all 30,000 patients to gain regulatory authorization or approval.
