This guidance relates to those people previously considered to be clinically extremely vulnerable. It contains a section relating to children which states the following:

Education settings

More evidence has emerged that shows there is a very low risk of children becoming very unwell from COVID-19, even for children with existing health conditions. Most children originally identified as clinically extremely vulnerable no longer need to follow this advice. Speak to your GP or specialist clinician, if you have not already done so, to understand whether your child should still be classed as clinically extremely vulnerable.

Those children whose doctors have confirmed they are still clinically extremely vulnerable are advised not to attend school while this advice is in place. Your school will make appropriate arrangements for you to be able to continue your education at home. Children who live with someone who is clinically extremely vulnerable, but who are not clinically extremely vulnerable themselves, should still attend school.

If your son or daughter has previously been in this category, please can we encourage you to contact your GP or consultant to clarify if you are able to continue to access school.

Kind regards,

Janis
