Four things I see:
1. Illegal immigrants are certainly reviving illnesses that were all but wiped out in the US. Whooping cough is a good example.
2. Some vaccines have passed the test of time and worth receiving.
3. Big pharma wants a steady stream of income to replace drugs going out of patent. The legal protection and steady schedule of vaccines looks like a winner. Pay attention to the news and you will hear about vaccines for everything from cervical cancer to gambling addiction or alcoholism prevention. Be wary.
4. You cannot find reliable reporting on the dangers of vaccines or pharma products in general. No organization wants to lose the revenue dollars generated by advertisements. Especially egregious are PBS and NPR. Underwriters my foot.
Big pharma does not profit from vaccines. Companies barely even recoup their costs of research for vaccines. They would rather invest research funding into drugs that are likely to give a decent return on the investment.
