Danish container line AP Moller-Maersk is in talks to ship more Covid-19 vaccines around the world.
The giant liner operator confirmed discussions with drug producer Pfizer, which this month became the first company to prove it had a working vaccine.
Several new contracts could be on the way, according to chief executive Soren Skou.
"We are in dialogue with Pfizer and others. We will do what we can to get these vaccines distributed as quickly as possible," he told the Berlingske Tidende newspaper.
"It will be good for the world, but thus also for us."
US biotech group Moderna also has an effective vaccine and the Oxford-AstraZeneca vaccine being tested in the UK is also set to be a major weapon in the fight against the pandemic.
At the end of October, Maersk revealed it had agreed to transport more than a billion doses of Covaxx's potential vaccine next year.
Emerging nations to benefit
"The goal is to bring a much-needed Covid-19 vaccine to emerging and developing nations," Maersk said.
The agreement lays out a framework for all transportation and supply chain services that will be needed to deliver the UB-612 vaccine around the world.
This covers end-to-end supply chain management, packing and shipping via air or ocean, ground transport, warehouse storage and distribution.
The vaccine, which is undergoing trials, activates both B-cells and T-cells in an attempt to mimic natural biology.
Pre-clinical studies have shown high levels of immune responses, Covaxx said.
Covaxx is a subsidiary of United Biomedical, founded in 1985 and headquartered in New York.
