COVID-19 vaccines for children Children aged 6 months to 11 years may be eligible for a COVID-19 vaccine if they have a condition which puts them at higher clinical risk of coronavirus. Getting the vaccine will help to protect your child against coronavirus. The vaccine helps to build up immunity to coronavirus, so the body can fight it off more easily. If your child is vaccinated, they are much less likely to get seriously ill from coronavirus or need to go to hospital. Infants and young children with underlying health conditions are 7 times more likely to be admitted to paediatric intensive care units with severe coronavirus, compared to those without underlying health conditions.
