An Additional Polio Vaccine Paves the Way for Eradication

A study completed at Imperial College London led researchers to conclude that combining both the common live oral polio vaccine (OPV) and the injected inactivated polio vaccine (IPV) gave children a much better immunity against the disease, a Reuters article reported. The study covered 450 children from Vellore, India, and was conducted by giving all participants OPV and half of them IPV. A month later, a “challenge” dose of OPV was given to simulate reinfection, and their stools were screened for the two existing forms of the disease. Children given IPV saw a 38 percent reduction in serotype 1 infection and a 70 percent reduction in serotype 3 infection.
