New Vaccine To Be Used For First Time In Polio Outbreak Response

...vaccine enables a precisely tailored immunological response to the type 1 poliovirus that is causing the outbreak. Compared to the commonly-used trivalent OPV, which offers protection against all three types of wild poliovirus, mOPV1 provides a greater immunity to type 1 wild poliovirus with fewer doses. Use ...
