Pakistan will require all travellers leaving the country to obtain a polio vaccination from June 1, the Health Ministry said on Tuesday.
A statement from the ministry said the restrictions comply with a decision by the World Health Organisation (WHO) advising travellers of all ages to be vaccinated by next month.
It said all provinces have been provided necessary guidance and material to set up special counters at hospitals and airports for polio vaccination and certification.
The ministry spokesman Sajid Shah said pregnant women traveling abroad are not exempted from the restrictions and the vaccination was not injurious for them.
