The World Health Organization (WHO) has issued a stark warning regarding the escalating risk of circulating vaccine-derived poliovirus type 2 (cVDPV2) in Yemen and the Horn of Africa region. The persistent humanitarian crises and security challenges are significantly impeding vaccination efforts and hindering access to children. According to the organization's latest report from its Emergency Committee, Yemen is experiencing a dangerous expansion of the immunity gap among children, particularly in the northern governorates. The report highlights that over 4.5 million children under the age of five are not receiving adequate oral polio vaccine response due to access difficulties and the prevailing security conditions. The report, released following the 45th meeting of the Emergency Committee, identifies Yemen as remaining within high-risk areas for international spread of the virus across the Horn of Africa. Concurrently, logistical challenges persist concerning the rapid air transport of acute flaccid paralysis samples from Yemen to laboratories for assessment and testing. The WHO emphasized that the ongoing vaccination gap threatens to exacerbate the spread of the virus, especially among the most vulnerable children. The organization has called for the facilitation of access for vaccination teams and the assurance of unimpeded vaccine delivery to all children. Furthermore, the WHO stressed the imperative to overcome the security and logistical hurdles that obstruct immunization campaigns. Enhanced surveillance and rapid response efforts are crucial to protect children and mitigate the risks of polio transmission amidst Yemen's ongoing humanitarian crisis. |
