Dear john,Yesterday, Robert F. Kennedy Jr. testified in front of Congress. When asked by my colleague if he would vaccinate his child for measles, he didn't answer the question directly.“For measles? Probably for measles I —” Mr. Kennedy began to answer before stopping himself. “You know, what I would say is, my opinions about vaccines are irrelevant.“I don’t want to seem like I’m being evasive, but I don’t think people should be taking medical advice from me,” he said.As the mission of the department he leads is to "enhance the health and well-being of all Americans, by providing for effective health and human services and by fostering sound, sustained advances in the sciences underlying medicine, public health, and social services," I don't understand how he can say anything less than an unequivocal "yes" to this question.
