Distributing a coronavirus vaccine will pose a major logistical challenge, but it is one the world can handle given adequate planning, the head of transportation for the United Nations Children's Fund told Efe Friday.

"I believe we have to remain optimists," Pablo Panadero said via video-conference from Copenhagen, where the Unicef Supply Center is located. "We are working 24 hours a day to improve the preparation."

Unicef is in contact with transportation and logistics firms and governments in nearly 100 low- and middle-income nations to ensure that the eventual Covid-19 vaccine reaches those people.
