An investigative reporter uncovered systematic data falsification in the 1998 publication. Most notably, the timing of first autistic symptoms was shortened from months to days for some children, and it was even reversed for some of the other children (these children actually had diagnosed symptoms before being vaccinated).

Since 1998, numerous studies have been conducted worldwide and none has found a link between autism and the MMR vaccine or any of its components. Select the correct description concerning the strength of the evidence for a causal link between MMR vaccination and autism in children in light of this additional information.

a. This additional information does not affect the strength of the evidence for a causal link between the MMR vaccination and autism in children.
b. This additional information casts doubt upon the strength of the evidence for a causal link between the MMR vaccination and autism in children.
c. This additional information casts doubt upon the strength of the evidence for a causal link between the MMR vaccination and inflammation of the colon in children.
d. This additional information does not affect the strength of the evidence for a causal link between the MMR vaccination and inflammation of the colon in children.
