Moderna warns against Omicron vaccine struggleAFP and AP, LONDON and NEW YORKExisting COVID-19 vaccines will struggle against the fast-spreading Omicron variant of SARS-CoV-2, the head of vaccine manufacturer Moderna said yesterday. Pfizer, another US drug maker, on Monday said that it began on Friday testing its current COVID-19 vaccine against the Omicron variant. However, the testing could show that existing shots “protect less,” which would mean “that we need to create a new vaccine,” he said. “Friday we made our first DNA template, which is the first possible inflection of the development process of a new vaccine,” he said. Meanwhile, the US Centers for Disease Control and Prevention on Monday broadened its recommendation for COVID-19 booster shots for all adults as the new Omicron variant is identified in more countries.
