A new vaccine that reduces food allergies in dogs could some day help people who suffer
dangerous reactions to food like peanuts, milk and wheat. The vaccine is also more
evidence in support of the so-called “hygiene hypothesis.” The Great Lakes Radio
Consortium’s Tracy Samilton reports:
Allergies to foods like peanuts have become much more common over the past 20 years.
Some researchers believe it’s because, as a hygiene-conscious society, we’re no
longer exposing our bodies to infections that stimulate the immune system and protect
us from allergies. Pediatrician Dale Umetsu of Stanford University mixed a component
of Listeria bacterium and peanuts into a vaccine. He then gave it to dogs
with allergies so severe that one peanut made them sick.
“After the treatment, the dogs could tolerate up, on average, to 30 to 40 peanuts,
so this was quite an increase and the effect lasted several months, at least,
after the treatment.”
Umetsu says it could be five years or more before a vaccine is available for human trials.
A vaccine could help millions of people with food allergies.
