British authorities will offer a coronavirus vaccine to almost six million children from age 5 to 11, officials said Wednesday.

The government said young children will be offered a low-dose COVID-19 shot on a “non-urgent” basis beginning in April in England. Scotland, Wales and Northern Ireland also announced similar measures.

“Parents can, if they want, take up the offer to increase protection against potential future waves of COVID-19 as we learn to live with this virus,” Health Secretary Sajid Javid said.

The government’s independent vaccine advisory committee said while the virus does not pose a threat to most children, a very small number who are infected will develop serious disease.

Around 85% of the 12 and older population in the U.K. has been fully vaccinated, but the country has lagged behind the United States and European countries like France, Germany and Italy in vaccinating younger children.

Currently, children 11 and under are only eligible for a vaccine if they have medical conditions that put them at serious risk of complications from coronavirus.

Authorities said Wednesday that young children will be offered two 10-microgram doses of the Pfizer/BioNTech vaccine, with an interval of at least 12 weeks between doses.

New coronavirus infections have fallen in many parts of the U.K., although the number of cases by age group remained the highest among schoolchildren. The official statistics agency reported Wednesday that around 1 in 13 or 7.6% of children ages 2 to 11 were likely to have had COVID-19 last week.

British Prime Minister Boris Johnson is expected to outline his government’s long-term strategy for “living with COVID” on Feb. 21.

Johnson said last week that all remaining domestic restrictions in England, including the legal requirement for infected individuals to self-isolate, could be lifted within weeks.

England has already scrapped most restrictive measures, such as mandatory face masks and vaccine passports for entering nightclubs and large events. Northern Ireland has lifted all legal restrictions.

Scotland has taken a more cautious approach. Face coverings still are required in indoor public spaces, and nightclubs check vaccine passports.
