You’re seeing the reports all over the news: Pfizer’s new coronavirus vaccine requires storage at -70C (-94F), which is much colder than the North Pole. If it’s not stored at this temperature, its ingredients begin to break down and it fails to work. Currently Pfizer is claiming, without evidence, that its vaccine is “90% effective.” But this claim is little more than corporate propaganda designed to drive up stock prices through false projections.
