There is an obvious attempt at association between anti-vax and the flat earth "conspiracy". Such "conspiracies" are always disseminated to weaken those actual questions of authority and concerns of validity.
At the very least, this dissemination is because various industries fear lost profits; at the very worst it is because the antivaxxers are right.
If we imagine an individual having the option to choose between several measles vaccines, then the problem is made apparent.
There can be no 'free play of economic forces' in the world of vaccination. For the public lacks the knowledge to assess vaccinations, and an individual cannot revoke their choice of vaccine.
In reality, the choice of any individual is limited to a single vaccine for any disease.
The argument is always based upon the sovereignty or the common good of the industries, and their mercenaries. In the sovereign case, they point to the storied history of its saintly immunologists, as if this at all guarantees all its current, and future, employees some divine grace. In the common good case, they argue that any generated profits are secondary to the concern for the wellbeing and health of the public; that these businesses suffer no immediate losses, economic or otherwise, from the failure of their vaccines shows these guarantees as empty. Nor could the business guarantee the continuance of this work for the common good, given the inevitable changes to its policies with changes to its staff and conditions.
The basis of the problem is Protocol Governance.
The governance by rule – the if A, then B – has occurred, increasingly, throughout history. It is the underlying premise of all bureaucratic systems, religious literalism, democratic governance, peer-to-peer and blockchain governance, statistical governance and rule of law. The variation in content belies the unifying element – the absolute sovereignty of the automatic protocol over human judgement.
This protocol governance always originates from the failure of political structures and their underpinning philosophical systems. The response by society to this failure is always a compulsion to scapegoat and sacrifice. The variation then, in this response, is the placement of this scapegoating upon the actors within the system, or the system itself.
