A 22-month-old toddler suddenly died on a family holiday after contracting Covid and another common virus, his parents say.
Dylan Findlay, who was born with a rare condition preventing him from swallowing, began vomiting on his first day at Disneyland Paris on March 13.
Used to dealing with the symptom, which is common in children with the condition, Alison and Robert Findlay put Dylan and his brother Niall to bed earlier than usual.
Dylan showed 'no signs' of the respiratory viruses which would later appear on initial results from post-mortem examinations, Alison says.
She became alarmed when Dylan started breathing quickly during the night, calling an ambulance and then asking for a private GP when she realised paramedics would not arrive for some time.
She told the Press and Journal newspaper: 'It took two hours for the doctor to get there, by which point Dylan’s appearance had changed.
'The GP and I had to perform CPR until the paramedics arrived.
'Niall woke up and saw this all happening. When paramedics got there they used the defibrillator on Dylan for 50 minutes but sadly he couldn’t be revived.'
The Findlays are now questioning whether Dylan could have been saved if he had been topped up with a preventative antibody treatment for RSV.
The boy had received the treatment in the winter of 2021 and recovered from a bout of the virus, which causes mild-cold like symptoms, the following March.
But the next winter he 'wasn't classed as vulnerable enough' to receive it again, Alison said.
'We'll never know the difference that could have made to him,' she added, telling the Press and Journal she and her husband will campaign for new guidelines on the issue.
Dylan was diagnosed at birth with tracheo-oesophageal fistula (TOF), which affects around one in 5000 children.
It usually requires surgery to allow patients to be fitted with a tube that pass food from the throat to the stomach for the rest of their life.
The Findlays paid tribute to their 'wee warrior' on Thursday, describing him as a 'happy, cheeky' boy who was 'always smiling'.
