NEW YORK — A United Nations polio vaccination campaign in Syria has provided protection to more than 355,000 children under the age of five in two governorates, where violence has made access especially difficult.

In response to a recent outbreak of vaccine-derived polio in the country, Unicef, the World Health Organisation (WHO), and aid partners have completed the first round of a vaccination campaign in the Deir EZ Zor and Raqqa governorates.

“Unicef applauds local partners and health workers for their extraordinary efforts and commitment to vaccinate children against this crippling illness,” said Fran Equiza, Unicef Representative in Syria in a statement.

“No child should have to live with the devastating effects of polio,” she added.

This is the second polio outbreak to hit Syria since the start of the conflict in 2011. The continued violence has devastated its health infrastructure and severely disrupted routine immunisation services, particularly in Deir EZ Zor and Raqqa.

Before the crisis, Syria was polio-free, with an immunisation rate over 80 per cent. National vaccination coverage is now just over 40 per cent.

“As of 18th August 2017, 33 children under the age of five have been paralysed,” said Elizabeth Hoff, WHO Representative in Syria.

According to Hoff, the detection of the circulating vaccine-derived polio virus type 2 cases demonstrates that disease surveillance systems are functional in Syria. “Our priority now is to achieve the highest possible polio immunisation coverage to stop the circulation of the virus,” she continued.

Unicef and WHO said they will continue engaging with local partners and health personnel in Raqqa and Deir EZ Zor Governorates to protect all children from polio.

Both agencies also call on all parties to the conflict to allow vaccinators full access to children in need.
