Relief on the Horizon for Allergy Sufferers?

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

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.

State and local officials say not all cities are prepared to respond to a bioterrorist attack. A recent
federal report indicates more coordination is needed. The Great Lakes Radio Consortium’s
Lester Graham reports:


Federal agencies need to set benchmarks that define what is adequate protection from
bioterrorism and need to develop a way for cities and states to evaluate and share useful solutions.
Those are recommendations from the General Accounting Office, the investigative arm of
Congress. The GAO found that state and local officials reported deficiencies in the number of
people needed, the coordination needed and the labs needed to address such things as
bioterrorism attacks or even new infectious diseases that can spread rapidly such as the West Nile
Virus or SARS. The GAO says the Department of Health and Human Services needs to work
with the Department of Homeland Security to get guidelines to state and local officials so that
they know what’s needed to protect the health of their residents.
