Supplementary immunization Activities:

Introduc�on:

Immuniza�on program goes towards its goal to sustain polio free status in Sudan through mass
immuniza�on program, sensi�ve surveillance system and improving quality of rou�ne ac�vi�es.

Introduc�on of IPV in rou�ne immuniza�on 2015 and keep con�nuing vaccina�on of target
children despite problems of global shortage is another milestone for PEI and RI program of the
country.

Sudan has not reported any case of polio posi�ve since 15th March 2009, there is op�mal level
of immunity at federal and states levels but we have to ensure the same level at some of the
locali�es

Sudan is considered as one of the six EMR countries at risk for importa�on of polioviruses. Inac-
cessibility, mainly due to security concerns in Blue Nile, South Kordofan SPLM-N controlled
areas and some areas in Darfur Zone makes it difficult for vaccinators to reach all children during
campaigns, resul�ng in subop�mal popula�on immunity of children in the age group < 5 years

in these areas.

Large popula�on movements at the interna�onal borders of Sudan increase the risk of importa-
�on of WPV through large pools of children in IDPs and South Sudanese refugee camps.

Sudan is hos�ng people from African countries including many Nigerians beside many Somalian.
Travel of residents of these countries through Sudan par�cularly during Hajj and Omrah seasons
and visits their rela�ves in Sudan states is another source of risk.

The Global Polio Eradica�on Ini�a�ve (GPEI) and the Horn of Africa Technical Advisory Group
(HOA-TAG) approved two rounds of supplementary immuniza�on ac�vi�es for Sudan during
2018.

First round was implemented in July 2018 and second round was convened according to the
plan 13th - 15th November 2017, Sudan used the bOPV during November SNIDs. The round
target high risk locali�es in 17 states of the country .

The target children for November 2017 round of SNIDs in Sudan were 4,510,305 less than 5
years children. Total of 4,437,692 (98%) of the target children were vaccinated by OPV during
November round in Sudan.
