The DTP (whole cell) vaccine was introduced in the late 1940s, but proved to be so dangerous that it was replaced with the DTaP (the acellular version), which was put into use in 1996 in the United States (DTP was still available in some doctor’s offices, and given in the U.S. until about 1999). It may have been used even after that in other countries.
Find more information about the DTaP, and how Boston University scientists as of fall 2017 find that it has never prevented whooping cough, and never provided any immunity to anyone, nor had it facilitated herd immunity. Link to post.
In an analysis of the three studies of the introduction of DTP in children ages 0 – 3, in urban and rural Guinea-Bissau (Africa) from 1980 – 1983, DTP-vaccinated children had twofold higher mortality than DTP-unvaccinated children.
In the initial studies and analysis below, the unvaccinated kids were the ones that were sick and malnourished – which is the reason that they were unvaccinated. Still, even though the unvaccinated children were sicker, they STILL fared better than the vaccinated.
Baby did a re-evaluation from 1981 – 1983, of equally nourished children, comparing vaccinated again unvaccinated, using a sample of 1,057 children. If children got DPT and oral polio vaccine, their death rate was increased 5 times. If children got the DPT vaccine alone, the death rate increased by 10 times compared with the unvaccinated children. The DPT vaccine had mercury in it at that time as well. Aluminum adjuvants that have replaced mercury in vaccines is just as neurotoxic.
This was Aaby’s conclusion:
These are the type of studies, or post marketing surveillance, that should be done for all vaccines. But, they are not done.
In addition, Aaby and other researchers wanted to know how the vaccine might be affecting the genetics of the recipients. They did a very small sample (8 girls) and looked at their genetics before the vaccine, and their epigenetics AFTER they received the vaccine. Epigenetics is a term used to describe how are genes change due to environmental factors. Vaccines are something that is introduced into our environment/body.
They found that the epigenetic changes (also called ‘modulations’) in each of the 8 girls were different. We don’t know of course which ingredient, or which ingredientS caused the negative epigenetic effects.
There was a related study done in Sweden in 2008. After infants receid DTap, polio and Hib at 3 and 5 months. “…array technology was used to assess the expression kinetics of immune response genes with association to asthma and allergy in peripheral blood mononuclear cells (PBMC) of five healthy infants after vaccination with Infanrix-Polio+Hib.”
On another vaccine, but showing again that there appears to be something very wrong with the ‘killed’ acellular vaccines, such as a the HepB, compared with live vaccines that wouldn’t need as much adjuvant as ‘killed’ vaccines do. *Note, mercury (thimerosal) was used as a preservative, whereas aluminum is used primarily as an adjuvant.
As an aside, several studies link some asthma cases to childhood vaccines and their timing. In a study of 1,531 children in Manitoba, Canada, researchers found that the risk of developing asthma by the age of seven was cut in half when the first diphtheria, pertussis, tetanus (DPT) immunization was delayed by more than two months. Delaying all three doses of DPT vaccines cut asthma risk by 60 percent.
