An outbreak of Polio linked with a vaccine-derived polio (VDPV) virus strain has been reported in the Morobe Province of Papua New Guinea. The news comes after a successful 2016 global switch from trivalent oral polio vaccine (OPV) to bivalent OPV together with the introduction of inactivated polio vaccine (IPV) to prevent VDPV. Polio vaccine coverage in Morobe Province has been previously reported to be low. The news are very concerning globally and more so to a country that had been certified polio-free for 18 years ( since 2000). The polio outbreak underscores the importance of maintaining high vaccine coverage at all times.
