2021 filings reveal Pfizer had reason to believe its COVID-19 vaccine’s effectiveness waned, although the company did not choose to release the information until months after the revelation.
“It’s clear from the documents that these analyses were almost four months old by the time they became public,” said associate professor at the University of Maryland School of Pharmacy Peter Doshi.
“It’s disappointing that neither Pfizer, nor regulators, disclosed these data until it was too obvious to ignore new outbreaks in Israel and Massachusetts, which made it clear that vaccine performance was not holding up,” Doshi continued.
Reporting from The Epoch Times:
Pfizer gave no explanation for why it delayed the publication of its data. The FDA did not confirm when it first learned about waning efficacy and Health Canada did not respond by the deadline.
