.. insisting on having complete immunity from any potential lawsuits.
I have discussed this ad nauseum.
They don't have "complete immunity" by any stretch of the imagination. If they committed fraud or falsified safety data, then their a$$ is grass.
Why do they have any immunity at all? Because vaccines are a highly litigious area and nobody would bother to do any biomedical research in the field, AT ALL, absent limiting liability. Same thing for pediatric medicines. Same thing for birth control medications, for women's health in general. Drugs in these classes can often get some governmental liability protection.
One historical precendent I know all of the details about was the discovery of the highly safe and effective anti-nausea drug Bendectin in the 1970s. It was made to essentisally eradicate morning sickness and it worked. It was also safe. But sometimes pregnancies result in birth defects. The rate of birth defects were exactly the same in Bendectin-treated women and those who didn't get Bendectin at all.
But if you are a woman who took Bendectin and got a birth defect, what do you do? You think "It was that bad drug!". I need to get me a lawyer. Call 1-800-BAD DRUG!
So one woman sued. She lost, because the data was clear.
Then another sued, and lost, because the data was clear.
another, and another, and another...
Repeat over a dozen times, the pharma company (Merrell Dow of Cincinnati) winning EVERY case.
What do you do as the pharma company? You lose millions of dollars in legal fees and get crappy press for a drug that doctors are afraid to prescribe anyway, since it is "in the news".
So the company says
1) Enough is enough, we'll pull this safe drug from the market because we can't afford to sell it.
2) Enough is enough, we won't work in women's health, EVER AGAIN. Too litigious.
I am familiar with the Bendectin case, since I met its inventor once. But the same crap has happened in vaccine development and in pediatric drugs.
That's why some liability is government-protected, to get research to be done, AT ALL, in those areas. We have the ambulance-chasing lawyers to thank.
