Médecins Sans Frontières/Doctors without Borders (MSF) says more than one thousand children have missed the measles campaign in Aweil that started on mid-February to early March this year.
The campaign targeted twenty thousand six hundred children from six months to five years old, but MSF says it only vaccinated 23, 000 children.
Dr Gabriel Kabilwa, Deputy Medical Coordinator told Bakhita Radio on Friday that the reason why the children missed the campaign was not clear.
He says MSF is yet to finalize preparations in areas that have missed the vaccination campaign.
Dr Kabilwa highlights that reaching the message of campaign to the people was a challenge.
He says the office did not receive cases of measles in Aweil center after the vaccination campaign.
