“This is based on what I feel.” That was the president last September, explaining why he wanted the measles, mumps and rubella (MMR) vaccine broken into three separate shots. On Monday, he signed an executive order instructing exactly that.
Four decades in intensive care have taught me what a feeling costs once it becomes national policy. Children will be hospitalized who did not need to be. Some of them will die. No one can name those the vaccine has saved, because prevented harm is invisible by definition, and that invisibility is what makes preventive medicine easy to dismantle and hard to defend.
