You doubt vaccines are money makers? Logically, if vaccine companies fund pro-vaccination campaigns without opening admitting the funding source (see California last month), there’s a profit motive involved. This was the same reason the insurance companies with pro-Obamacare - they were looking at the impact of a slew of mandatory customers coming their way.
From what i've been reading, both vaccines and anti-biotics tend to have very small profit margins compared to "drugs."
That vaccines make some profit cannot be denied, else no one would make them at all, but this is a very different thing from claiming that they make large profits.
Again, from what reading I have done on the subject, it would appear that vaccines do not.
