Yes, we should be skeptical. We should ask questions. The regulators should be skeptical of drug companies, and the public should be skeptical that government regulators aren't getting too cozy with the drug companies. But not just for future generations, but for the here and now. If we remain skeptical, then the future is taken care of, or at least as much as we can do about it today.
Well, got a better idea? Vaccines are quire clever in that they help the body's own immune system recognize and kill microorganisms that cause diseases. It's not the same as, say, antibiotics, where over-prescription can accelerate the evolution of antibiotic-resistance strains of bacteria.
The use of vaccines has been one of the great medical success stories, with very few downsides. It is a landslide win for vaccines. But some idiots insist on focusing on the negative, and inventing negative stories around vaccines. And I'd bet they are responsible for more death and suffering than vaccines have ever caused.
