'End of the Beginning'

The future of vaccines may rest in the antibodies of cows. Scientists at the Scripps Research Institute recently published a study in Nature on how cows create antibodies that block HIV infection, even though cows don’t get HIV.

“The cow immune system has to deal with keeping in check all these microorganisms,” says Vaughn Smider, a professor at Scripps. Cows’ extra-long antibodies “can potentially bind into … areas where a typical antibody from humans or mice may not be able to bind.”

Scientists say this study shows how HIV outwits the human immune response, and they believe it marks “the end of the beginning” in HIV vaccine research.
