Look at Lyrica it has a FIFTY PERCENT FAILURE rate due to bad side effects and yet they want to expand it's use to a 4th disease.
If you have side affects from a drug all your doctor does is switch you to a different one, and it does not get reported, doctors don't have time or financial resources to do so, nor does your drug store.
I'd like to see the stats on all the senior citizens who get flu shots then catch pneumonia or some other opportunistic infection and die. I'll wager you they're not too keen on keeping stats like that.
