Vaccine boosters are 90% effective against hospital admission of the Omicron variant for those over 65, new figures show.
Figures from the UK Health Security Agency show this level of protection three months after those over 65 received the booster.
Meanwhile, protection for people taking two doses fell to about 70% after three months and to 50% after six months.
In light of these data, the Joint Committee on Immunization and Immunization has advised the government against giving a second booster dose, or fourth injection, to residents of nursing homes and people over the age of 80.
He added that priority should continue to be given to deploying the first booster dose and that unvaccinated people should come forward for their first two doses as soon as possible.
Professor Wei Shen Lim, president of JCVI on Covid-19 vaccination, called the data “very encouraging.”
âCurrent data shows that the booster continues to provide high levels of protection against serious illness, even for the most vulnerable age groups.
âFor this reason, the committee concluded that there was no need to introduce a second booster dose immediately, although this will continue to be reviewed.
âThe data is very encouraging and underscores the value of a wake-up call.
âAs Omicron continues to spread widely, I encourage everyone to come forward for their booster dose or, if not vaccinated, for their first two doses, to increase their protection against serious illness. “
