One step closer to eradicating polio

Researchers from Imperial College London and international partners, explains the persistence of the disease in northern India, one of the few remaining places in the world where endemic polio has not yet been eradicated. They argue that the simple measure of using a ‘monovalent’ form of the polio vaccine alongside the standard ‘trivalent’ form in these areas could sufficiently increase the effectiveness of vaccination programmes to wipe out the poliovirus where it persists.
