Dr Ngozi Okonjo-Iweala, a former Minister of Finance and Chairman, Global Alliance for Vaccines and Immunisation (GAVI), has urged the Federal Government to improve on immunisation coverage.
Okonjo-Iweala made the appeal in an interview with newsmen in Umuahia.
She commended the Federal Government for efforts made so far but urged government to work harder to attain the average target set for Africa.
Okonjo-Iweala described GAVI as the largest and 10-billion dollar organisation in the world, taking care of vaccination and immunisation of children all over the developing world.
According to her, the organisation has so far immunised more than 760 million children and saved more than 13 million lives.
