The bolus theory of vaccinations makes an argument that the random nature of bolus damage can (and does) damage all parts of human physiology.

The increase in vision issues seen in modern children is hypothesized to be at least partially caused by increased vaccination schedules (more bolus’ and thus a greater chance of damages to all parts of the body increasing incidences of all conditions through time). Could be a factor.

I tend to believe there is a strong case to be made for modern diet and vaccination schedule being the two primary causes of human health issues seen en mass today. But I cannot prove that’s THE truth though I can make a very strong case for both vectors with a lot of credible evidence.
