Here is a novel approach: vaccinate taxi drivers, for free, at a major transit area, the airport. This is precisely what is being done in Chicago, as reported here by the Chicago Tribune. Taxi drivers are in contact with a wide variety of people, particularly air travelers, who cough, sniffle and sneeze in their cabs. A taxi driver's risk of influenza contagion is not inconsequential.
This is a clever vaccination campaign provided that a large fraction of Chicago's taxi cab drivers are vaccinated.
