That's a hard one to answer, and there are many possible answers.
One thing is true though, that if they admit the mistake they have made in causing so many cases of autism (and other type of damage and death) 
that the government and pharmaceutical companies would go broke from all the lawsuits,
and people would lose confidence in the vaccine industry.
Basically heads will roll.
This type of thing has happened before.  When it was discovered that the original Polio vaccine was contaminated with a monkey virus SV-40 that causes cancer,
the government decided to keep it quiet and fire the scientists who discovered it, 
because they did not want to admit their mistake to the people.
I have a great book about that whole incident.

In the case of the polio vaccine, they started out with good intentions, but were utterly unwilling to admit failure and the fact that they started a possibly worse problem than polio, the huge rise in cases of cancer.

So we could speculate that people were completely evil in intent from the beginning in regards to autism,
or we could realize that even if it started out with good intent,
once the scientific attempt to manipulate and play God goes bad,
that they will continue to refuse to be accountable at all cost ... and at that point it doesn't matter if they are putting people in a worse place than they were before they attempted to play God in the first place.
