Baltimore-area doctors made a public stand in favor of vaccines Monday, standing literally shoulder to shoulder to urge holdouts to get their kids vaccinated against measles. "Ours is an unequivocal message. Vaccines are safe, they are effective, and they save lives every single day," Baltimore City Health Commissioner Dr. Leana Wen said as the group stood up in front of a seminar about measles at the Johns Hopkins University school of public health. "The Disneyland outbreak raises the real risk that measles may come roaring back. We have come too far to let that happen," the group said in a statement.
