The Joint Committee on Vaccination and Immunisation (JCVI) said it has updated its advice regarding Covid-19 vaccinations for children aged between five to 11 to help prevent "severe" Covid-19 illness.
However, the JCVI also says that "Children aged 5 to 11 years who are not in a COVID-19 clinical risk group are at extremely low risk of developing severe COVID-19 disease".
And that for "vaccination to have a substantial impact on school absences, persistent high levels of vaccine-induced protection against non-severe infection are required".
But it said the offer to vaccinate children was a "one-off pandemic response programme".
