She is saying clearly and specifically that she is pro vaccination.
I don't think that is trying to play both sides.
She is categorically sceptical about the requirement for widespread, unquestioned prescription of drugs manufactured and marketed by "predatory big pharma".
She highlights the strength of the influence that the pharma lobby has on politicians and the fact that FDA oversight and regulation relies predominantely on trust that pharma companies are upfront about the scope, standards and results of clinical trials.
I think that it is legitimate to be sceptical on that front and to shine a spotlight on the deficiencies in the drugs approval process.
