The effectiveness of COVID-19 boosters is expected to decline in the coming months, and people may need a second shot in the fall of 2022, Moderna Inc. CEO Stephen Bansley said at a conference on health conference hosted by Goldman Sachs on Thursday.
Bansal said the company is working on a vaccine candidate for the omicron variant of coronavirus, but it is unlikely to be available in the next two months.
“I still believe we need a booster in the fall of ’22 and to move on,” Bansley said.
His remarks on the need for a fourth shot, citing a study by Israeli Prime Minister Naftali Bennett on Tuesday, said that the fourth dose of the Covid-19 vaccine increases antibodies five times a week after the shot is taken.
Moderna, which benefits from repeated inoculation, said in its third-quarter earnings results that the commercial booster market in the United States could reach 2 billion in 2022.
