That really depends on who benefits from said consensus.
Actually drug companies typically lose money on vaccines. They would generally prefer not to make them but they do it because someone has to. Drug companies make way more money on other drugs. Even with govt subsidy to make them it's not in their best interest except out of goodwill.
So basically you are saying that the "establishment" wants people to get autism so badly that they are wiling to lose money over it? That hardly sounds reasonable.
