Flu vaccine shortage: it isn't profitable:
Business competition has diminished largely because federal and state health departments undervalue the vaccine and refuse to guarantee the purchase of fixed amounts. One by one private companies have dropped out of the vaccine business in favor of more lucrative enterprises, such as pharmaceuticals, and the ones that remain use a cheaper but outdated manufacturing system that is vulnerable to contamination.The bottom line is that the government (specifically the FDA; I'll see if I can find some dates) concentrated the manufacture of the vaccine for government programs with a few companies to artificially drive down the cost. So a couple of companies hold a stranglelock on the manufacture of the vaccine, simply because it's not competitive for other companies to get into the market. In other words, the government outsourced the manufacture of flu vaccine overseas to two primary labs.
In a bungled attempt to privatize vaccine manufacturing, the Food and Drug Administration has discouraged competition and diversity when adequate supply not necessarily lower prices is the top goal. If the government is going to outsource vaccine manufacturing, it has to make the deal worthwhile for manufacturers. Otherwise it should do the job itself, which would cost more but at least guarantee proper supplies.
It's got nothing to do with trial lawyers, and everything to do with corporate profits.
In other words, it's just business.
