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.
Of course you want people to rely on YOUR “some reading” like you are the Official Reader.
Except that drugs are giving to sick people, while vaccines are given to nearly everyone. Low margins in large volumes translates to big profits. I assume you’ve heard of Wal-Mart?
