MMR Vaccines May Not Prevent Mumps Infections

Here is an alarming report about mumps. Apparently, children are developing malignant mumps infections following "successful" MMR vaccinations:

I think the vaccine industry does not know what it is doing. They cannot improve on 400,000+ years of human evolution by giving us dozens of vaccines.

So what is their real agenda?

At one point in human history, vaccines which saved human lives may have made sense. Now that humans are overwhelming the planet, do vaccines which allow more of us to survive really contribute to "public health", or are they doing the opposite? Can the human population be "healthy" if we are killing the planet?
