The number of sufferers has soared in recent decades, too, with a 2017 study suggesting prevalence in children had risen 21 percent since 2010.
The new study involved a trial, called the Artemis trial, undertaken at hospitals across Europe.
175 children with peanut allergies aged 4 to 17 took part in the research, which saw them given either increasing amounts of peanut allergen protein or a placebo every day.
Those who took the peanut protein were given a slightly higher dose every two weeks for six months, after which point the same dose was maintained for three months.
The researchers found that 58 percent of children who’d taken the peanut protein could tolerate at least three to four peanuts by the end of the trial.
It compared to just 2 percent of those given the placebo.
The researchers concluded that the treatment “led to rapid desensitization to peanut protein.”
The research does not suggest peanut allergy sufferers will soon be able to eat peanut butter by the spoonful, however the researchers hope it could mean less severe reactions from accidental exposure to the nuts.
One participant, James Redman, 12, told The Times that he can now tolerate up to seven peanuts after previously suffering severe reactions to any peanut traces.
