Pediacel


Manufacturer: Sanofi Pasteur MSD Limited Generic name: Diphtheria, tetanus, pertussis (acellular, component), poliomyelitis (inactivated) and Haemophilus type b conjugate vaccine (adsorbed) Pediacel Safety Pediacel safety trials were small-scale and short-term and only compared adverse reaction to other vaccines. All trials were conducted by the manufacturer, who was in full control of which data to include in the study or present to the regulators. Side-effects recorded since the vaccine was approved can be very serious. They include meningitis, convulsion, encephalopathy, SIDS and sudden death. The number of such adverse reactions reported are very low. For example the FDA, in a 2008 review, mentioned 14 deaths over a period of 9 years. However, vaccine side-effects are widely under-reported and only data forwarded by the manufacturer was analysed in this FDA review. The vaccine contains a number of toxic ingredients, including Aluminim phospate, a neurotoxin, Phenoxyethanol, a reproductive toxin and Polysorbate 80, which can cause severe non-immunologic anaphylactoid reactions. During the time of the previous DPT vaccine there was widespread concern over the amount of patients suffering serious side-effects [3,5], incl. neurological damage, following vaccination. Several studies found a link [12,13], while others found no link [7] or were inconclusive [6,9]. The vaccine was also suspected of increasing the likelihood of asthma later on in childhood. [10] One study found those links too but then adjusted the data [11] after which there was no link. Both sides of the argument accused each other of using data selectively and studies can be found “proving” either side of the argument. In most cases, only those children who showed symptoms within 7 days of vaccination were included in studies. The problem was the pertussis part of the vaccine, which one can obviously not avoid in a combined vaccine. Pediacel is a different type of vaccine and…
