New York Times: “Researchers have not linked the combination MMR shot to a risk of death, and there is no evidence that it is dangerous or that splitting it into its three components is any safer or more effective, vaccine experts said. Combination shots for the diseases have been used in the United States since 1971, and were introduced only after careful comparison against individual shots. They have been given to hundreds of millions of children.”“What’s more, separate vaccines for measles, mumps or rubella have not been available in the United States for many years. Vaccine manufacturers said it would take a minimum of five to 10 years for them to be tested and made available.”
