Absolutely the adverse reactions are under-reported as such.

And the whole point of vaccines is virulence, the patient is purposely infected by toxins in order to cause an immune reaction.

Which is why there are no long term studies on the effects of vaccines.

 "Any conclusions drawn from inhomogeneous cases will be suspicious. All events or occurrences of the disease must be true cases of the disease.

This is why the medical system constantly changes the parameters of diagnosed disease, it hides the mode-earn medical failures and invents new disease in its place.

"It is important to collect as much information as possible about each event in order to inspect a large number of possible risk factors. The events may be collected from varied methods of epidemiological study or from censuses or hospital records."

Long term studies in general overlook many factors, and draw from spurious records.

Finally.... no test has ever been done with vaccines and long term effects, confirming the hypothesis that vaccines do not cause chronic disease.

And as we know..."Because epidemiological studies can rarely be conducted in a laboratory the results are often polluted by uncontrollable variations in the cases. This often makes the results difficult to interpret. Two methods have evolved to assess the strength of the relationship between the disease causing agent and the disease."
