One way world officials are trying to help eradicate polio is by partly focusing on the cold chain.
According to Business Recorder, the government of Japan, Japan International Cooperation Agency and the United Nations Children's Fund, signed an agreement to use funds to help eradicate polio in Pakistan, where the virus is still very prevalent.
Part of the $5.4 million grant will go to help strengthen "the vaccine management through provision of cold chain and logistic personnel at Federal, FATA and four provinces," according to the report.
"This grant addresses urgent needs of current polio situation in Pakistan and will enable children to acquire rapid immunization among children influx from FATA who have had zero dose since June 2012 and children who hardly get immunity with OPV [Oral Polio Vaccine]," said Mitsuyoshi Kawasaki, Chief Representative of Japan International Cooperation Agency Pakistan.
