The CDC’s webpages http://www.cdc.gov/vaccinesafety/index.html tout a large number of studies of the short term effects of vaccination, events say within 72 hours of receipt.
However, they don’t cite any studies on the long term effects of vaccines. Can vaccines damage development in infants? Do they stunt your growth or make you fat? Do they make you stupid? Do they damage the immune system? How long does vaccine protection last? Does its nature change qualitatively over time in ways that might create danger? For example, after a period of years, may your immunity wane to the point where you can become a carrier of diseases for which you were vaccinated? They don’t report data on these subjects.
The CDC says http://www.cdc.gov/vaccinesafety/Vaccines/multiplevaccines.html
“No evidence suggests that the recommended childhood vaccines can “overload” the immune system.”
(Emphasis added.) This is a blatant lie (eg: http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0008382 and much much more below and elsewhere), but also it begs the question:
why don’t they report empirical studies on the subject rather than asserting ignorance? Aren’t they in charge of studying such issues?
There is a scientific literature on these matters. Virtually every study of which I’m aware, that studies the long term effects of vaccination on the development of children’s or infant animals’ immune systems or brains, finds that vaccines are highly damaging to development.
This includes studies injecting infant animals with the aluminum in the vaccine series or with antigens, which unanimously report the animals develop abnormally, including brain damage and auto-immune disease. Examples are http://www.jneurosci.org/content/28/27/6904.full and http://www.ncbi.nlm.nih.gov/pubmed/21643765 and http://lup.sagepub.com/content/21/2/195.abstract and http://www.sciencedirect.com/science/article/pii/S0162013413001773.
The literature also includes randomized placebo test of a flu vaccine in children, followed by following their health for a sustained period. The vaccinees got 4 times as many respiratory illnesses as the recipients of placebo.
Other studies, both human and animal, report that flu vaccines can damage the immune system
The literature also includes epidemiological studies, that compare kids who got more and earlier vaccines to those getting fewer and less. For example, nations with fewer vaccines in the series have much less infant mortality http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3170075/.
States with lower vaccine compliance have much less autism. etc. http://www.ncbi.nlm.nih.gov/pubmed/21623535 There are many more.
The study the CDC touts http://www.cdc.gov/vaccinesafety/Concerns/Autism/antigens.html as evaluating parents’ concerns of “too many vaccines too soon” and autism is
(a) written by a lead author who also was lead author on another study which his own collaborator says was improperly manipulated to hide a vaccine-autism connection. Do they really need to rely on him as their sole source for arguing vaccines don’t cause autism?
(b) compares patients by the number of “antigens” they receive, rather than the number or earliness of vaccines. Table 1 in De Stefano et al 2013 http://jpeds.com/webfiles/images/journals/ympd/JPEDSDeStefano.pdf defines what is meant by this. DTP has 3002 antigens while no other common vaccine in their data set had more than a handful. That means that patients who got DTP and other vaccines had more than 3000 antigens and were the high antigen group, compared to patients who may well have gotten equally many or earlier or more vaccines, but didn’t get DTP. (Many of them got DTaP instead.) This study compared two groups of patients that seem likely to have gotten roughly the same number of vaccines, and the same earliness, and the same aluminum. It doesn’t seem they would have found a different result, for example, if the aluminum in vaccines were the sole cause of autism.
The CDC also don’t tout any papers on how long vaccine protection lasts. In fact peer reviewed articles (see previous blog post) indicate that a few years after last booster, immunity may be waning for most people to the point where they can become carriers of the disease. So the vaunted “Herd Immunity” seems more, according to the published science, like “Herd Weakening and Contagion”. As far as you might gather from the CDC’s site, vaccine immunity is eternal and unpiercable.
If the CDC were seriously interested in regulating the manufacturers, (and they should be since Congress has indemnified the manufacturers, so if the CDC doesn’t regulate them, who will), after seeing a placebo controlled study showing that a flu vaccine destroyed the immune systems of the kids who received it http://www.ncbi.nlm.nih.gov/pubmed/22423139 they would surely at a minimum demand such a study for every vaccine. For flu shots the results would of course come too late every year, but at least they might get some confidence over time. And they might compensate the recipients of vaccines that placebo controlled studies showed had gotten damaged immune systems. Heck, the manufacturers could offer a guarantee: we’re doing a double blind randomized test on the side. If you get our vaccine, and the placebo test shows it destroys your immune system after all like the last placebo test did, we’ll refund your money, and buy you an ice cream for the inconvenience.
According to Richard P. Feynman, it is incumbent on a scientist to emphasize everything that could be wrong with his theory, not sweep it under the rug. When this is widely disregarded, cargo cult science results.
I genuinely don’t want to do Cargo Cult Science so if anybody reading this knows of any citations to studies looking at the long term effects of vaccines and finding them benign or beneficial, please, be sure to post them in the comments.
