The story of the first MMR vaccine
Incidence of mumps virus meningitis:
“Vaccine-associated meningitis occurs around three weeks after immunisation generally. In those instances reported so far it appears to be a milder and more transient illness than meningitis from wild virus. This is what one might expect with an attenuated virus. The risk benefit ratio therefore remains strongly in favour of the immunisation of all children with any MMR vaccine. However the MMRII vaccine is preferred where this is available because of the much lower risk of vaccine associated meningitis.”
We have a letter from the Japanese Department of Viral Disease and Vaccine Control which indicates that from April 1993 the use of the MMR vaccine (all types) was stopped in Japan and that vaccines would be available only in their monovalent form (i.e. single virus)
The Japanese findings indicate that adverse reactions to these types of MMR vaccine were up to 78 times as frequent as our Government’s Chief Medical Officer of Health has admitted. If those figures are correct, then the vaccine is more dangerous than the illness; and it does not give a great deal of confidence that the Government has got its figures (or information about safety or side effects) right. Note also that this article was published in March 1991. Yet the two brands of MMR implicated with these side effects were not withdrawn until September 1992, some 18 months later.
Indeed TRIVIRIX (a MMR vaccine containing the Urabe strain virus) was withdrawn in Canada in May 1990. Why did the UK Government take till 1992 to withdraw it?
