evidence: Tedros Adhanom Ghebreyesus’ statement came four days after Pfizer said it has data to support its repeated claim that a third dose of its vaccine will be needed to keep protection levels high. He also singled out Moderna, which, like Pfizer, is developing updated vaccines targeted at variants. "We’re making conscious choices right now not to protect those in most need," Tedros said in Geneva. [...] Tedros said the world needs Pfizer and Moderna to prioritize supply of vaccine to low- and middle-income countries, including through COVAX, a joint endeavor of the WHO, Gavi, the Vaccine Alliance, and CEPI, the Coalition for Epidemic Preparedness Innovations.
