Qatar has banned Nigerian travellers who do not have valid polio vaccination certificate from entering the country.

According to the Federal Capital Territory administration, the Department of State Service (DSS) drew its attention to a report that Qatari authorities had resolved to ban all Nigerian citizens travelling to the country without valid certificate of vaccination against polio with effect from June 29.
The report said the ban was a precautionary measure to guide against the spread of the disease in that country.
“In view of the above, John Obinna Chukwu , FCT permanent secretary, wishes to intimate all stakeholders and intending
travellers, particularly those resident in the FCT on the need to obtain duly signed and stamped yellow book on polio and other communicable diseases,” a statement issued by the FCT administration on Sunday said.
“Chukwu reiterated that obtaining of this yellow book on polio and other communicable diseases is very necessary to avoid embarrassment at the port of entry into the country.”
