People suffering with coeliac disease have been given hope by scientists who believe they may have found a vaccine.
A world-first clinical trial is currently underway in Melbourne, Australia, with the hope being that coeliacs could one day be able to ditch their gluten free diets.
Doctors are using injections to help reprogramme sufferers’ abnormal reaction to gluten found in some bread, pasta, flours, cereals, cakes an biscuits.
It is estimated that about one in 100 people have coeliac disease, writes Wales Online.
Symptoms include anaemia, stomach cramps, mouth ulcers, diarrhoea, constipation, vomiting, stomach cramps and fatigue, with about one in 10 people suffering from the disease.

The condition occurs when the body’s immune system attacks its own tissues as the gluten protein – found in wheat, barley, rye and oats – is eaten.
This causes damage to the lining of the gut, meaning the body can’t properly absorb nutrients from food.
The only treatment currently available for coeliacs is to stick to a gluten-free diet which eases most of the debilitating symptoms.
In extreme cases the condition can lead to issues such infertility, type 1 diabetes, osteoporosis and even small bowel cancer.
Coeliac disease in the UK
- Charity Coeliac UK says it takes 13 years on average for a person with coeliac disease to be diagnosed
- At least 1 in 4 people diagnosed with coeliac disease had previously been diagnosed with IBS
- Around 45,000 people were diagnosed with the condition in the UK between 2011 and 2015
- But it is claimed around half a million people in the UK are still without a diagnosis
But researchers say they are hopeful the pioneering vaccine will bring an end to these restrictive diets.
Lead researcher and gastroenterologist Dr Jason Tye-Din, from the Royal Melbourne Hospital told The Herald Sun the vaccine targets gluten-specific cells.

He said it teaches the body how to handle gluten more efficiently so that it doesn’t go into “attack mode” every time someone with coeliac eats a meal.
“If you can give [the vaccine] in successive injections, you can retrain the immune system so it learns to develop a tolerance,” he said.
“This trial is important in establishing clinical proof-of-concept for a treatment that would provide benefit beyond that of the gluten-free diet.
“If the trial is positive, it would suggest that having a normal diet is something people can aim for. That’s the ultimate hope.”
To take the vaccine to the next stage, Dr Tye-Din is recruiting almost 150 patients from across Australia, New Zealand and the United States to trial the injections.
All of the participants will either receive the active injection or a placebo while undergoing three food challenges, which test the vaccine for its symptomatic relief.
Sarah Sleet, chief executive of Coeliac UK, said this trial was “an important step” towards finding a vaccine for coeliac disease.
But she warned that further research and clinical trials are needed to ensure there are no side effects and that the vaccine is of benefit.
She said: “In total, there have been four phase 1 trials that showed that NexVax 2 is well tolerated. The vaccine will initially be assessed in combination with a gluten-free diet to protect people from accidental gluten exposure, not as a full replacement for the gluten free diet, although this is ultimately the end goal.
“Advances in the field of treatment of coeliac disease are exciting and promising. However, a cure will be many years in development.”
