Port operator DP World has made an offer to transit COVID-19 vaccines for free into the UK. It offers to do this through their quaysides and their subsidiary P&O Ferries. The offer is widely reported in the UK press, at the same time as distribution has begun under military-level security. The vaccine, developed by Pfizer-BioNtech in Belgium, requires cryogenic cold-chain transportation. It has been suggested that rail mounted super-cool reefers could be used for reliable dispersal to inland vaccination centres.
