Katie Price has shared the sweet note her son Harvey has written to the NHS after visiting hospital over the weekend.
The 18-year-old had a reaction to the Oxford/AstraZeneca vaccine caused by the 'complex medication' he's on for his 'complex needs.'
Harvey has partial blindness, the genetic condition Prader-Willi syndrome, autism and Attention Deficit Hyperactivity Disorder (ADHD).
Katie, 42, said she was 'thrilled' when her eldest son received the vaccine on Friday as his pre-existing conditions left him vulnerable to coronavirus.
Following the hospital scare, the mum-of-five assured fans Harvey was well and thanked fans for their best wishes.
Katie has now shared a note Harvey wrote to NHS staff on Instagram, captioning the picture of the letter: "I can’t resist showing you this what @officialmrharveyprice has written today with no help ... it amazes me everyday what must go through Harvey’s mind."
The hand-written message read: "Dear NHS doctors and nurses I am writing to say well done for looking after Harvey and everybody and doing a good job with my injection on Friday.

"You are all proud of me. You work hard everyday. We all need a holiday. I will send you more pictures to keep you happy and safe thank you and well done love from Harvey Price."
Many of Katie's 2.3m followers flooded the post with messages about the "sweetest boy".
One wrote: "Aww Harvey what a lovely letter, as a Paramedic I would be over the moon to receive something like this well done you and so glad you ok again."
"Bless him, what a sweetheart," another said.
A third added: "He has the sweetest heart ever and is beyond amazing. You are both such an inspiration."
