Vaccine safety is one of the major areas of  concern of the anti-vaccination crowd.  Guillan-Barre syndrome is a subset of said concern; it is feared that some vaccines might increase the incidence rate. It appears the science-based evidence is a bit unclear on the issue. Luckily this is being followed closely by scientists all over the world. One such group of scientists recently published a study in the New England Journal of Medicine which addresses the concern.

The vaccinated vs unvaccinated study - a.k.a. The German Study

I have previously reported on a newish trend in anti-vaccine propaganda, the “vaccinated vs. unvaccinated study” gambit. The anti-vaccine proponents have retreated to this new position after the thimerosal, MMR-autism and other hypotheses of theirs were shown to be worthless. This …..strategy is well known to anyone with a basic understanding of logic as moving the goal post. Superficially, the request does not sound unreasonable. Why not compare the non-vaccinated with the vaccinated and see if there is any increased risks with vaccination? To be clear, I am not against such research being done, to the limit it can practically ———->FULL ARTICLE

READ THE FULL ENTRY AT SCIENCE BASED MEDICINE Last year it was reported that there was a possible increase in narcolepsy, a sleep disorder characterized by excessive sleepiness, in children who had received the Pandemrix brand of H1N1 flu vaccine in Sweden, Finland, and Iceland. However a review of the data did not find a convincing connection, although concluded there was insufficient data at present and recommended further surveillance. A narcolepsy task force was formed in Finland, and now we have their preliminary report. They conclude that the evidence suggests there is a connection: Based on the preliminary analyses, the ———->FULL ARTICLE

A recent study, published in the journal Pediatrics in December 2010, provides further evidence that the pentavalent rotavirus vaccine is effective in reducing hospitalization and emergency visits attributable to rotavirus gastroenteritis, without increased risk of intussusception or other serious adverse events, among infants aged 6-12 weeks of age.

Journal Club Debunks Anti-Vaccine Myths

READ THE REST OF THIS ENTRY AT SCIENCE BASED MEDICINE American Family Physician, the journal of the American Academy of Family Physicians, has a feature called AFP Journal Club, where physicians analyze a journal article that either involves a hot topic affecting family physicians or busts a commonly held medical myth. In the September 15, 2010 issue they discussed “Vaccines and autism: a tale of shifting hypotheses,” by Gerber and Offit, published in Clinical Infectious Diseasesin 2009. The article presented convincing evidence to debunk 3 myths: MMR causes autism. Thimerosal (mercury) causes autism. Simultaneous administration of multiple vaccines overwhelms and weakens ———->FULL ARTICLE

Today we will look at the recent recommendation by the CDC, the American College of Obstetricians and Gynecologists,  that, all people over 6 months of age, including pregnant women receive the flu vaccine. Anti-vaccination groups have already come out,  insinuating that the safety of the flu vaccine given during a woman’s pregnancy has not been established. Is that true? Are there any studies that have looked at the safety of the influenza vaccine for pregnant women? The answer is yes, at the very least there is one that I was able to find, using simply Google. Safety of influenza vaccination ———->FULL ARTICLE

A recent study published in the Journal of the American Medical Association (JAMA) has found an association between the 7-valent pneumococcal vaccine (PCV-7) and an increase in nasopharyngeal (in the nose and throat) acquisition of pneumococcal serotype 19A strain, which is not one of the 7 strains the PCV-7 protects from. According to the authors of the study, a possible association had been observed between the use of PCV-7 vaccine and a rapid increase in serotype 19A strain acquisition, but studies had never been done to confirm this association, and the current study is the first one to address that ———->FULL ARTICLE

READ THE FULL ARTICLE AT DOTmed.COM Common vaccinations don’t raise risk of rheumatoid arthritis, easing fears that they’re linked to the inflammatory disease, according to a new study. Case reports have suggested vaccines, possibly because of their immune-activating adjuvants, could trigger rheumatoid arthritis, a painful autoimmune disease caused by the body’s natural defenses attacking and inflaming joints. But a study published online Tuesday in the Annals of the Rheumatic Diseases found no link between common vaccinations for flu, hepatitis, diphtheria and other illnesses and an increased risk for rheumatoid arthritis. The study also found no increased risk for patients getting ———->FULL ARTICLE
