The children will be vaccinated against measles, polio, rubella and other diseases that can be prevented.

This month marks the fiftieth anniversary of the Salk vaccine against polio. Today the Americas have been declared polio-free. Smallpox has been ended worldwide. And there has been progress against measles. Health officials in the Americas are also working to end another disease, rubella, through vaccination.
