According to scientists, while most adults were vaccinated against the disease when they were children, the immunity provided for by the vaccines has since been reduced and needs to be revamped.
According to health ministry officials, over two million children have never received a polio vaccine while around 4.7 million are protected against Polio Type 1 and 3 but not type 2 which is believed to be circulating in the country.
Dr. Alfred Driwale, the Manager Uganda Expanded Programme on Immunization (UNEPI) told journalists on Thursday that they have proposed to the technical committee handling the refugees that the visitors should be vaccinated against both type 1 and type 2 strains of the virus irrespective of their age.
