There is no Covid-19 vaccine yet, but IATA is already working with airlines, airports, global health bodies and drug firms on a global airlift plan.
The distribution programme assumes only one dose per person is needed
Well first from what I read in the specialized press, an effective vaccine is likely to require 2 doses a few weeks/month apart, as the antibodies do not seem to last long against this virus. .
But that aside , most large countries have vaccine productions plants able to deliver enough for their local populations . ( i.e. China, India, Europe, USA, Japan , etc..) so the demand for air transport will be limited to smaller countries. and are likely to be a one-off run in a limited period of time . Do not really see the problem .
The major difficulty of mass distributing a vaccine is the public health infrastructure on the ground, not to mention the publics willingness to actually be vaccinated - not the distribution between countries.
Quite agree with that.
