Pfizer/BioNTech COVID-19 vaccine

To unblind or not to unblind? That is the question about clinical trials of COVID-19 vaccines

Antivaccine alternative health tycoon Joe Mercola claims that the unblinding of participants in the clinical trials of Moderna and Pfizer COVID-19 vaccines was intended to "blow up the trials" and undermine the science, making it impossible ever to identify long term adverse events. What he's really doing is deceptively oversimplifying complex ethical and scientific issues surrounding these trials in the middle of...
