The risk of Covid in children is very low
One argument for not vaccinating children against Covid is they get relatively little benefit from it.
"Fortunately one of the few good things about this pandemic is children are very rarely seriously affected by this infection," said Prof Adam Finn, who sits on the UK's Joint Committee on Vaccination and Immunisation.
Infections in children are nearly always mild or asymptomatic, which is in sharp contrast to older age groups who have been prioritised by vaccination campaigns.
A study across seven countries,
published in the Lancet, estimated that fewer than two out of every million children died with Covid during the pandemic.
Even children with medical conditions that would raise the dangers of a Covid infection in adults are not being vaccinated in the UK at the moment. Only those at "very high risk of exposure and serious outcomes" - which could include older children with severe disabilities in residential care - are recommended to be vaccinated.
The vaccines are incredibly safe, but the risk and the benefit still have to be carefully weighed.
