This, from a family physician, about the ‘law of vaccine supply and demand‘:
Remember the H1N1 epidemic from 2009? The country was obsessed with the bird flu, like they are now with Ebola. My patients were scared to get the bird flu, and they refused the regular flu vaccine because H1N1 was initially not included. Then, a few months later, H1N1 was included. What happened? Suddenly, demand dropped. In the vaccine world, when there is no supply (like the current Ebola non-vaccine) or [limited] supply, the demand goes way up. However, when there is an abundance of flu vaccine (like this year), many patients gladly refuse the vaccine.
