“It’s like a new beginning,” Looney, 53, told The Associated Press. Right away, “the energy I had was amazing. To have a working kidney — and to feel it — is unbelievable.”Concerned by rhetoric about how vaccines are tested, a group of doctors recently compiled a list of more than 120 vaccine clinical trials spanning decades, most of them placebo-controlled, including for shots against polio, hepatitis B, mumps and tetanus.

“It directly debunks the claim that vaccines were never tested against placebo,” said Dr. Jake Scott, a Stanford University infectious disease physician who’s helping lead the project.Antivaccine groups argue that some substances scientists call a placebo may not really qualify, although the list shows simple saline shots are common.

Sometimes a vaccine causes enough shot-site pain or swelling that it’s evident who’s getting the vaccine and who’s in the control group — and studies might use another option that slightly irritates the skin to keep the test “blinded,” Scott explained.And when there’s already a proven vaccine for the same disease, it’s unethical to test a new version against a placebo, he said.
