Health InsuranceA Vaccine For Ear Infections - Without The Needle
Even when she"s well, little Cammy Barber doesn"t like getting her ears
checked - and for good reason. She"s only nine months old and has already had eight ear
infections. And her mom, Coleen Barber, will tell you, treating them isn"t always easy.
"The shots are awful to see the child have to get, but even the medicine alone, they don"t like
the flavor of it, at this age, it"s hard to sneak it into anything," says Coleen.
So scientists at Nationwide Children"s Hospital are working on an Alternative involving just a
single drop of liquid. A drop that"s not injected or even swallowed, but simply rubbed onto the
outside of the ear. And best of all, it"s a vaccine designed to stop ear infections before they
ever start.
Experts say it could someday help kids everywhere, especially those with no other
alternatives. And lab test are promising.
"It was extremely effective. So we"re very excited about the ability to maybe immunize
without needles and deliver this vaccine to the poorest children in the world," says Lauren
Bakaletz, PhD, a researcher at Nationwide Children"s hospital who developed the vaccine.
Dr. Bakaletz says it works by activating cells just under the surface of the skin, called
dendritic cells. When this liquid touches the skin, it touches off a response throughout the
body.
"These cells deliver it to the lymphoid organs where it can generate an immune response. So
really harnessing a power that"s there all the time, but you"re doing it in a way that"s now
directed toward a specific disease," says Dr. Bakaletz.
Dr. Bakaletz, who is also with the Ohio State University, says work still needs to be done
before the vaccine is tested on kids - but if someday could help babies like Cammy live more
care-free, pain-free lives.
It is estimated that 83% of all kids get ear infections before their third birthday** and
another child gets an ear infection every 2.3 seconds in this country.* In fact, it is the
number one reason kids are taken to the emergency department.**
