Sweden will give a fourth shot of Covid-19 vaccine to people aged 65 and above to boost their defences against the disease, the health agency said.
“For people aged 65 and over, it is now four months since the previous vaccine dose, and the protective effect of the vaccine diminishes over time,” the health agency said in a statement.
Sweden had previously offered a fourth jab to people aged 80 or older, Reuters reports.
