What a disaster, but not exactly unforeseen -- because it is a necessary failure of central planning.viewtopic.php?f=18&t=2221&p=11981&hilit=mises#p11981
There must be some other article that you meant to reference because the article whose link you provided is written by someone who keeps talking about how Novartis had a monopoly on US vaccine production. That's simply not true as there were 5 firms, Novartis, Sanofi-Aventis, CSL Limited, Glaxo Smith Kline, and MedImmune who received contracts to provide vaccine.
The reason 5 firms were selected was because it was thought that if any one or two or whatever might encounter production problems, the others would still be able to achieve peak production levels. Instead, unknown to everyone but the most skilled psychics, ALL of the firms had problems getting the H1N1 virus to grow in eggs.
Nobody's fault. That's a function of the virus strain against which the firms had to protect AND the fact that H1N1 was identified very late in the year and well past the time when there might normally be an influenza target selected.
But, all in all, notwithstanding those problems, I think we have been and are in pretty good shape in the US.
