Kennedy was pressed repeatedly on thehe’s delivered on vaccines, which public health experts have said are hampering efforts to contain

now in at least 11 states.Responding to Sen. Chris Murphy, a Democrat of Connecticut, Kennedy refused to recommend that parents follow the nation’s childhood vaccination schedule, which includes shots for measles, polio and whooping cough. He, instead, wrongly claimed that the vaccines have not been safety tested against a placebo.Sen. Bill Cassidy, a Republican of Louisiana and chairman of the health committee, had extracted a number of guarantees from Kennedy that he would not alter existing vaccine guidance and work at the nation’s health department. Cassidy, correcting Kennedy, pointed out that rotavirus, measles and HPV vaccines recommended for children have all been tested in a placebo study.

As health secretary, Kennedy has called the measles, mumps and rubella vaccine — a shot given to children to provide immunity from all three diseases — “leaky,” althoughfrom the measles for most people. He’s also said

, although none has been documented among healthy people.

“You have undermined the vital role vaccines play in preventing disease during the single, largest measles outbreak in 25 years,” Democratic Sen. Bernie Sanders said.“We do find that it could function a little bit in a human being,” Wang said. He speculated that would be enough to help support a failing human liver.

In the U.S. last year, surgeons at the University of Pennsylvania attempted that sort of “bridge” supportto a brain-dead human body to filter blood, much like dialysis for failing kidneys. U.S. pig developer eGenesis is studying that approach.

In China, Wang’s team didn’t remove the deceased person’s own liver, instead implanting the pig liver near it.That “clouds the picture,” said Dr. Parsia Vagefi, a liver transplant surgeon at UT Southwestern Medical Center who wasn’t involved with the work. “It’s hopefully a first step but it’s still, a lot like any good research, more questions than answers.”
