Sweden's public health agency has recommended a fourth dose of the Covid-19 vaccine for people over the age of 80, those in nursing homes and those receiving at-home care.
The agency said the jab should be taken four months after the previous dose, at the earliest, AFP reported.
In Sweden, more than 85 per cent of those over the age of 80, have received a third dose of the vaccine, as have 55pc of over-18s.
