The original vaccines still offer good protection against severe illness and death. Studies in the U.S. and elsewhere have made clear that adding a booster dose strengthens that protection and improves the chances of avoiding a milder infection.
COVID-19 vaccine makers have been updating their shots to better match omicron in case global health authorities decide the change is needed.
“We recognize the need to be prepared in the event this protection wanes over time and to potentially help address omicron and new variants in the future,” Kathrin Jansen, Pfizer’s vaccine research chief, said in a statement. In one study group, about 600 volunteers who received two doses of the current Pfizer vaccine three to six months ago will receive either one or two omicron-based shots as boosters. Another 600 who’ve already gotten three regular doses of the Pfizer vaccine will be given a fourth dose of either the regular vaccine or the omicron-matched version.
