"After more than 40 years of submitting pertussis vaccine to the mouse toxicity test, children are still dying and being brain-damaged after the vaccine has passed this test." – Dr K Geraghty paediatric immunologist.
‘Drug manufacturers and the FDA have known since at least the early 1960s that the mouse toxicity test bears little relation to adverse reactions in children. Knowing that the vaccine was not being properly evaluated for toxicity, they continued to inject it into more than sixty million children during the following 20 years.’ – Coulter/Fisher, A Shot in the Dark, 1991
"The only safety testing that has ever been done on the pertussis vaccine in the past 50 years is an unproven method called the Mouse Weight Gain Test. The "scientists" inject the vaccine to be tested into the stomachs of baby mice. If the mice continue to gain weight and don't die right away, it is assumed the vaccine is safe and effective for humans. That's it! I'm not making this up!.......The only toxicity test required for the initial licensing of the DPT vaccine in the United States was this mouse weight-gain test 60 years ago."-----The Sanctity of Human Blood By Tim O'Shea p. 69
"Testing laboratory staff inject vaccine into the abdomens of mice, then weigh them regularly. If the mouse loses lots of weight, apparently the vaccine is more likely to cause brain damage in your child. (Corbel, M.J. et al. 2004. "Toxicity and potency evaluation of pertussis vaccines". Expert Rev. Vaccines 3(1): 89-101. PMID: 14761246. It is stated that this test "correlates with adverse reactions" yet in the next breath they go on to say its "mechanism is unclear". (I can't work out how weight loss equals brain damage either, actually.) They also say it's not a useful procedure for acellular vaccines.)"--Just A Little Prick by Peter and Hilary Butler p. 115
