Eradicating polio (finally)

A new vaccination strategy in India could finally eliminate polio by the end of the decade.

In northern India, particularly Uttar Pradesh and Bihar, the polio virus persists, despite good vaccination coverage, due to overcrowded living conditions and poor sanitation. Researchers at the Imperial College in London say that the three polio strains in the trivalent vaccine can interfere with each other inside the body, producing immunity to one strain but not another. So switching from a vaccine that protects against three strains of polio to a vaccine that protects only against the dominant one, along with stepped up vaccination efforts, could help eliminate the virus from its few remaining reservoirs.
