Guaranteed safety first required to restore trust

With both President Xi Jinping and Premier Li Keqiang issuing harsh, personal condemnations and ordering thorough investigations of the company at the heart of a vaccine scandal, the chairwoman and four senior executives of the Changchun Changsheng Bio-tech Company are now in police custody and under investigation for criminal liabilities.

Seeing some heads roll will certainly serve to pacify the public's anger. But this is not the first major vaccine-related scandal, and will that suffice to prevent another repeat?

Probably not. Because this is not a mere matter of one lawless company taking advantage of a porous quality guarantee regime.
