Orin and Olivia Arthur are seven-year-old twins living in the Highlands with Pompe Disease who have taken a step towards ending months-long shielding after receiving their first Covid vaccinations.
They have been shielding at their home in Tain, Easter Ross, for 22 months along with their parents Lyndsay and Stephen Arthur.
Mrs Arthur said the vaccinations were a "Christmas dream come true."
The rare condition means the twins require specialist care. Even a common cold can lead to them having to spend time in intensive care in hospital. Mr and Mrs Arthur have been calling for vaccinations for their twins for the past year.
Earlier this week, the UK government said vulnerable primary school children aged five to 11 should be offered a low-dose Covid vaccine.
The Arthurs believe the twins are the first under 12s in Scotland, and possibly the UK, to have the vaccine. They have praised NHS Highland and Public Health Scotland for getting the vaccinations to them.
