Whenever scientists create a vaccine  COVID-19, governments worldwide will be scrambling  cargo aircraft. Distributing the vaccine will be one  the biggest logistical operations ever. Aviation experts have forecast that transporting the vaccine  the globe will require  8,000 747 freight planes. This is sufficient to ship 7.8 billion doses  any vaccine - one dose  everyone on Earth. The International Air Transport Association (IATA) has warned governments they must start planning  the "mission of the century". It said: "Even if we assume that half the needed vaccines can be transported  land, the air cargo industry will still face its largest single transport challenge ever."
IATA has warned governments that many obstacles must be overcome to ensure the effective distribution  a vaccine. One critical element  this is the creation  temperature-controlled cargo hubs and warehouses. It is essential the vaccine be kept  the same temperature  its journey. This would require extensive training  staff worldwide, who must quickly become expert  safely handling and moving the vaccine. IATA said a further challenge would be security and cross-border controls. It said: "Vaccines will be highly valuable commodities. Arrangements must be  place to ensure that shipments remain secure  tampering and theft."
