When Big pharma is most interested in causing death and mayhem.

Why would the single vaccines for measles, mumps or rubella suddenly disappear from the "shelves"? Big pharma could make 3x as much money selling the singles to those concerned parents, instead of selling one MMR.

So, Big pharma is lying. Their science is invalidated.

Where do we go from here? We would have to start afresh with the data, new studies and new hypothesis.
