Vaccines: Are vaccines necessary or dangerous?
Some folks argue that improved sanitation and diet have decreased the incidence of disease, not vaccines. Well, sanitation and diet haven't improved in India, and they have nearly eradicated polio there through vaccinations. The sanitation conditions in India have not improved in leaps and bounds, as ours has, since the 1950s.
Arguably, the Native Americans had the cleanest drinking water, freshest streams, heavy metal pollutant free, most natural foods, and no artificial preservatives in their diet. They maintained active, healthy lifestyles and got plenty of exercise and fresh air.
Yet the Native Americans saw somewhere between 90% and 95% casualty rates when exposed to small pox - a viral infection spread by contact. Small pox also had a virulence rate (rate of infected who die) of 30% in the general European population when exposed. It is a terrible disease, but inoculation was a tried and true method of reducing fatality down to 1 or 2%.
How did Franklin Roosevelt get polio with the high-tier sanitation in his mansion again? Of course, vaccinations, exercise, healthy diet, and sanitation are all useful in reducing risk for disease. It's not helpful to avoid any of these keys to good health.
By looking at the big picture, we see that most measles cases occur among the unvaccinated population, not the inoculated population http://www.ecdc.europa.eu/en/press/news/_layouts/forms/News_DispForm.aspx?List=8db7286c-fe2d-476c-9133-18ff4cb1b568&id=935&RootFolder=%2Fen%2Fpress%2Fnews%2FLists%2FNews&Source=http%3A%2F%2Fwww.ecdc.europa.eu%2Fen%2Fpress%2Fnews%2FPages%2FNews.aspx&Web=86661a14-fb631-43e0-9663-0d514841605d , http://www.ecdc.europa.eu/en/publications/Publications/measles-rubella-surveillance-oct-2013.pdf. Diseases like measles are coming back because more people are not getting their vaccines. It's not because people are running out of clean water.
It's no coincidence that, where vaccines aren't rigorously applied, disease outbreaks occur. "Where kids aren't vaccinated, more people get sick. In 2011, the states with lenient policies about immunization exemptions had 90 percent more whooping cough cases than stricter states" http://www.iom.edu/~/media/files/report%20files/2013/childhood-immunization-schedule/childhoodimmunizationscheduleandsafety_rb.pdf , http://www.popsci.com/science/article/2013-07/popsci-guide-anti-vaccine-claims.
Many people don't use them, because they are afraid of vaccinations. Do vaccines cause autism? Nah, it's the organic food craze https://www.facebook.com/photo.php?fbid=10103817074489045&set=p.10103817074489045&type=1&theater.
The most recent, large-scale review - concerning MMR inoculations and autism - finds no significant link between MMR vaccines and autism http://www.ncbi.nlm.nih.gov/pubmed/22336803. Earlier studies also report that MMR vaccines don't increase your risk for autism http://www.ncbi.nlm.nih.gov/pubmed/19952979 ,
http://www.ncbi.nlm.nih.gov/pubmed/18769550 ,http://www.ncbi.nlm.nih.gov/pubmed/18252754 ,http://www.ncbi.nlm.nih.gov/pubmed/10376617. Actually, MMR vaccines may have prevented several cases of autism spectrum disorders http://www.ncbi.nlm.nih.gov/pubmed/21592401. A review of 120 studies concluded that MMR vaccines do not place you at risk for Crohn's disease, ulcerative colitis, autism, or aseptic meningitis http://www.ncbi.nlm.nih.gov/pubmed/12922131.
Of course, thimerosal-vaccines don't increase your risk for autism http://www.nap.edu/catalog.php?record_id=10997 ,
http://www.ncbi.nlm.nih.gov/pubmed/15342856 ,http://www.ncbi.nlm.nih.gov/pubmed/15342825 ,http://www.ncbi.nlm.nih.gov/pubmed/14519711 ,http://www.ncbi.nlm.nih.gov/pubmed/15342824 ,http://www.ncbi.nlm.nih.gov/pubmed/14595043 ,http://www.ncbi.nlm.nih.gov/pubmed/17508426 ,http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3018252/ ,http://www.ncbi.nlm.nih.gov/pubmed/23949514).
A recent meta-analysis concluded that there is no significant relationship between vaccines and autism, including no relationship between thimerosal-inoculations and autism http://www.ncbi.nlm.nih.gov/pubmed/24814559. Such conclusions were replicated by an analysis of over 40 vaccine-safety studies, presented by the American Academy of Pediatrics https://www.aap.org/en-us/documents/immunization_vaccine_studies.pdf.
To quote from a 2009 review, "Twenty epidemiologic studies have shown that neither thimerosal nor MMR vaccine causes autism. These studies have been performed in several countries by many different investigators who have employed a multitude of epidemiologic and statistical methods" http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2908388/.
The autism and thimerosal link weakens when we realize that Sweden and Denmark experienced major elevations in the rates of autism, which occurred at the same time when they lowered the thimerosal levels in their vaccines http://www.ncbi.nlm.nih.gov/pubmed/12880876 ,http://www.ncbi.nlm.nih.gov/pubmed/12949291). Reducing levels of thimerosal has not affected the rates of autism, since the rates of autism continue to rise http://www.ncbi.nlm.nih.gov/pubmed/18180424 ,http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3018252/. Surprisingly, a study in Canada reported that the rates of pervasive developmental disorders are higher among folks who are not exposed to thimerosal, once compared to people who get thimerosal inoculations http://www.ncbi.nlm.nih.gov/pubmed/16818529.
Before people move the goal post and claim that aluminum in vaccines increase the risk for autism, let's put it in perspective: "During the first 6 months of life, infants could receive about 4 milligrams of aluminum from vaccines. That’s not very much: a milligram is one-thousandth of a gram and a gram is the weight of one-fifth of a teaspoon of water. During the same period, babies will also receive about 10 milligrams of aluminum in breast milk, about 40 milligrams in infant formula, or about 120 milligrams in soy-based formula... About half of the aluminum in the bloodstream is eliminated in less than 24 hours and more than three-quarters is eliminated within two weeks. The ability of the body to rapidly eliminate aluminum accounts for its excellent record of safety" (http://www.chop.edu/export/download/pdfs/articles/vaccine-education-center/aluminum.pdf). Aluminum is present at such low levels in all vaccines, that no change in aluminum content is required (http://www.chop.edu/service/vaccine-education-center/vaccine-safety/vaccine-ingredients/aluminum.html).
Importantly, vaccines don't result in neuro-psychological/cognitive deficits (http://www.ncbi.nlm.nih.gov/pubmed/23588083 , , , , ,
Another myth is that vaccines cause diabetes. Obviously, vaccines do not increase your risk for diabetes (http://www.ncbi.nlm.nih.gov/m/pubmed/22075092/ , , , ,
And it's ridiculous to say that vaccines cause cancer. Exposure to SV40-contaminated vaccines is not associated with cancer incidence (http://jnci.oxfordjournals.org/content/95/7/532.long , , , If contaminated vaccines are not linked to cancer, it's safe to say that non-contaminated vaccines do not cause cancer. Surprisingly, Hib vaccination is associated with reduced risk of childhood leukemia (http://www.ncbi.nlm.nih.gov/pubmed/15951359 ,
Vaccinated folks actually have lower rates of asthma compared to non-vaccinated people (http://www.ncbi.nlm.nih.gov/pubmed/24461583). Most research finds that inactivated split-virus influenza vaccination does not exacerbate underlying respiratory diseases (http://www.ncbi.nlm.nih.gov/pubmed/24868213). And don't worry, most studies find that childhood vaccinations don't make people more likely to develop atopic disorders (http://www.ncbi.nlm.nih.gov/pubmed/23991838 , , , ,
Not to mention, pregnant women who are vaccinated have better birth outcomes compared to non-vaccinated mothers (http://www.ncbi.nlm.nih.gov/pubmed/24396098 , , ,
Vaccination for pregnant mothers can reduce their infection rate by 89% (http://www.ncbi.nlm.nih.gov/pubmed/22487092). Infection rates are higher among unvaccinated women, once compared to vaccinated women (http://www.ncbi.nlm.nih.gov/pubmed/21955086).
The same applies to children. Kids who receive vaccines are not at increased risk for infections (http://www.ncbi.nlm.nih.gov/pubmed/11023764 , A recent study found that kids who received the MMR vaccine were less likely to be admitted to the hospital for any infection treatment (http://www.ncbi.nlm.nih.gov/pubmed/24570246).
Children handle multiple vaccines given in one setting, in the same way they handle a single vaccine injection (http://pediatrics.aappublications.org/content/109/1/124.full).
Delaying vaccination is associated with higher risk for fevers and seizures following inoculation (http://www.ncbi.nlm.nih.gov/pubmed/24126936 , Any febrile seizure that follows incoluation is not serious and does not increase risk for neuro-developmental complications (http://www.scientificamerican.com/article/delaying-vaccines-increases-risks-with-no-added-benefits/ ,
What was that? Vaccines cause ear infections? That's not what the peer-reviewed data finds. As you can see, vaccination has fought against such infections (http://www.sciencedaily.com/releases/2013/11/131125164654.htm ,
While there are ineffective vaccines, the effective vaccines (especially the influenza vaccine) reduce mortality in the general population (http://www.ncbi.nlm.nih.gov/pubmed/24656243). Interestingly, a meta-analysis of randomized controlled trials found that influenza vaccines reduce your chances of experiencing adverse heart complications (http://www.ncbi.nlm.nih.gov/pubmed/24150467). Plus, the flu vaccines have prevented a few million cases of the flu (http://www.plosone.org/article/info:doi/10.1371/journal.pone.0066312).
Most side effects of vaccines are minor anyway (http://www.ncbi.nlm.nih.gov/pubmed/22612789). As shown in a 2014 systematic review, serious adverse events that follow vaccination are "extremely rare" (http://pediatrics.aappublications.org/content/early/2014/06/26/peds.2014-1079.abstract). Generally speaking, inoculations are safe (http://www.ncbi.nlm.nih.gov/pubmed/24265819 , , , , ,
And an analysis of reports submitted to the VAERS found that vaccines only caused a small percentage of harms - most of which were minor (http://www.ncbi.nlm.nih.gov/pubmed/?term=23063829). Keep in mind, folks, VAERS is a public database that anyone can post on. Just because someone submits a report about a possible vaccine injury, doesn't mean that the injury was caused by a vaccine.
Besides, any adverse event that occurs as a result of vaccination is overshadowed by the benefit of inoculations (http://www.phac-aspc.gc.ca/publicat/cig-gci/cedv-cemv-tab-eng.php). Why? Because vaccines reduce health-care costs substantially by largely preventing or nearly eliminating cases of diphtheria, pertussis, tetanus, poliomyelitis, measles, mumps, rubella (including congenital rubella syndrome), influenza, invasive Haemophilus influenzae type b (Hib), hepatitis B, hepatitis A, rotavirus, varicella, and herpes zoster (shingles) (http://www.ncbi.nlm.nih.gov/pubmed/18000199).
In fact, there have been double-blind, placebo-controlled trials on vaccines - proving their efficacy and safety (http://www.ncbi.nlm.nih.gov/pubmed/17602732 , , , , , , , , ,
The Institute of Medicine concludes that vaccines carry few risks (http://www.iom.edu/Reports/2011/Adverse-Effects-of-Vaccines-Evidence-and-Causality.aspx). It's not like vaccinated folks have higher rates of health issues compared to non-vaccinated individuals. To quote from a German study, "In addition to atopic disorders, we further compared diseases—such as obstructive bronchitis, pneumonia and otitis media, heart disease, anemia, epilepsy, and attention deficit hyperactivity disorder (ADHD)—in unvaccinated and vaccinated subjects. No relevant differences in the lifetime prevalences were found, neither for different age groups nor between girls and boys" (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3057555/).
Ultimately, nature's immune boosters=diseases. You can't get specific immunity without exposure to the pathogen itself, in one form or another - in a vaccine or as the wild-type disease. Vaccines come with fewer side-effects than diseases, by several orders of magnitude.
