Poliovirus Outbreak in Burundi and Congo Linked to Vaccines.

Health officials in Burundi and the Democratic Republic of Congo have detected cases of vaccine-derived poliovirus, which is different from wild poliovirus and occurs when a weakened strain of poliovirus contained in the oral polio vaccine circulates among under-immunized populations for long periods. The detections are significant as they are the first linked with the use of a new vaccine, the novel oral poliomyelitis vaccine type 2 (nOPV2), which was developed specifically to reduce this risk.

New oral polio vaccine linked to polio cases for the first time.

Seven children in the Democratic Republic of the Congo and Burundi have been paralyzed by viruses from a new polio vaccine, known as nOPV2, which was developed to minimize the risks associated with the oral polio vaccine. The vaccine-derived viruses have also been found in environmental samples collected from Burundi. The Global Polio Eradication Initiative, which includes partners such as the Bill and Melinda Gates Foundation and the World Health Organization, had anticipated this risk. While the new vaccine is an improvement, experts warn that the low levels of immunity to type 2 polio could amplify the problem of vaccine-derived viruses.
