Routine childhood vaccinations will have prevented hundreds of millions of illnesses, tens of millions of hospitalizations and more than 1 million deaths among people born between 1994 and 2023, according to the US Centers for Disease Control and Prevention.

A new report, published Thursday by the CDC, analyzed the benefits of routine childhood immunizations in the United States through the CDC’s Vaccines for Children Program, which launched in 1994. The research also found that the vaccinations saved the country billions of dollars.
