Hepatitis B vaccine - An urgent need of re-appraisal
Further a publication on the risk of multiple sclerosis after hepatitis B vaccine , this paper briefly summarizes evidence pointing to an unusual toxicity of this vaccine.
It was rejected by the Editor-in-chief on the following basis: "It is too difficult to understand. I do not think that it adds sufficiently to the thoughtful and balanced editorial and the original paper".
Performed by an American team on a British database, Hernan et al’s investigation (14 Sept, 838-842) is a definite blow for all those who upheld the lame argument that doubts on the safety of hepatitis B vaccine (HBV) would refer to a new French paradox. It is not true that "numerous studies have not corroborated the association [with multiple sclerosis]" (p. 772-773).
The inconsistencies of some  were so gross that in its public report of Feb 2000, the French Agency recommended to "discard" this contribution.
The biases of DeStefano et al (2003)  were blatant (e.g. imbalance between cases and controls for their neurological history).
Of the 3 case-control studies undertaken by the French Agency, all of them showed an increase in the risk of post-vaccinal multiple sclerosis (MS), lack of statistical significance being simply an expected consequence of a repeated lack of statistical power: in a Correspondence discussing the biases of Ascherio et al’s investigation , the French investigators asserted that the American results were consistent with "the same increased risk" as in France and concluded that "at best", it was now impossible to rule out an "epidemiologically important increase in risk"...
Another strong argument for iatrogenic causality is given by an impressive increase in paediatric MS, a very rare entity prior to mass vaccination in children. In France, where "hard" epidemiological data are scarce, those of the national system of health insurance showed an impressive increase in MS as well as in "severe neuromuscular disorders" after mass vaccination. Dozens of reports have been published suggesting a worrying link between HBV and a number of non-neurological auto-immune diseases .
In addition to these articles, two case/control studies performed by the French agency (Feb 2000 report) demonstrated a statistically significant increase in the risk of Graves’ disease as well as that of lupus.
The only point on which one cannot agree with Hernan et al is about the benefits of HBV, for at least 3 reasons: 1) data on hepatitis B hazards are more consistent with manufacturers interests than with epidemiological evidence ; 2) there remains an unusual uncertainty about the duration of immunity given by this vaccine; 3) as there is ample evidence that the hazards of this vaccine, not only neurological, have been systematically neglected, there is an urgent need for a re-appraisal the benefit/risk ratio of this vaccination.
