The findings could bring down the cost of immunization, an important consideration in developing countries, some of which have had trouble containing the paralytic disease.

A needle-free jet injector made by Bioject Medical Technologies was used to deliver the vaccine beneath the skin at ages 2, 4 and 6 months. Blood tests showed more than 95 percent of the infants mounted an effective immune response against polio.

Babies who got a lower dose had fewer antibodies against polio but the researchers said that should not be a problem.

"It's still way over what would still be considered protective levels," Dr. Roland Sutter of the World Health Organization said in a telephone interview.

1. Fantastic news!

I think a lot of the low vaccination rates could be solved by widespread adoption of needle-free injectors. I think it's the needle that gets most folks to skip a vaccination, really.
