Booster shots are providing high levels of protection against hospitalization and severe disease from the omicron Covid variant among older people, according to the latest data from the U.K. Health Security Agency.
Figures show that around three months after the third shot, protection against hospitalization among those 65 and older remains at about 90%. With just two doses, protection against severe disease drops to about 70% after three months and to 50% after six months, the agency said Friday.
