Whenever Kate and Jamie Scott’s seven-year-old son writes a card for his daddy, it contains the same fervent wish.

‘He always says ‘I hope you feel better soon, daddy’, because he doesn’t understand that you can’t get better from a brain injury the size of a credit card,’ says Kate.

The bewilderment of her eldest boy and his four-year-old brother is ‘another layer of heartbreak’, as 36-year-old Kate puts it, on top of everything she and her husband have already endured – and they have endured a great deal.

Three years ago in April, Jamie suffered a catastrophic bleed on the brain after being given the AstraZeneca Covid vaccine.
