…because this new entry into the vaccine research world is anything but convincing that it is helpful.  Here we look at the effectiveness of so-called “TDap” vaccine usually administered to children and teenagers roughly 6 times before they graduated from high school. This represents a tetanus, diphtheria, and “a cellular” pertussis vaccine against these illnesses.  Note that the incidence of pertussis in the school with the greatest amount of vaccine coverage, School A (65%), had almost 50% more cases of pertussis than School B (42%). Of course, the conclusions were that “Tdap was moderately effective in preventing disease him unvaccinated students.” Not only was it only “moderately effective” it was actually less effective than in a population of students who received a lot less of the vaccine.  I’m sure that this will be argued that it was not a large enough study or that the statistical power was inconclusive or some such other nonsense. However the study was significant enough to be published as a major entry in Vaccine, a mainstream pro-vaccine medical journal.

It is actually quite astonishing that more parents don’t actually read the package insert before allowing a near total stranger to inject a bunch of chemicals into their infants and toddlers. Say what she wants about “vaccine deniers”, but the think any parents ever read the package insert?  Deal actually think that there are any “Safety and Efficacy” data included in the package insert as is required by most FDA approved drugs? Lets take a look at Infanrix, the most common product used in most clinics in the United States for TDaP shots:

 About INFANRIX Vaccine in Brief

  • Ages: Infanrix is a 3 in 1 shot (diphtheria, tetanus, acellular pertussis vaccines) given to children under age 7 (see GlaxoSmithKline product insert for recommended schedule and other indications).
  • Estimated Efficacy: The mechanism of protection from B. petussis disease is not well understood. A serologic correlate of protection for pertussis has not been established. In clinical trails the efficacy of the acellular pertussis vaccine component was 86 to 89 percent.
  • Use With Other Vaccines: In clinical trials, Infanrix was given with HIB, pneumococcal, hepatitis B, inactivated polio or MMR vaccines. There is no information in the product insert about the safety or effectiveness of giving Infanrix simultaneously with inactivated or live influenza, rotavirus, varicella or hepatitis A vaccines.
  • Commonly Reported Adverse Events: Pain, redness, and swelling at the site of the injection; drowsiness; irritability/fussiness; loss of appetite.
  • Other Serious Reported Adverse Events: Hypotonic-hyporesponsive (collapse) episode; persistent cry for 3 or more hours; high fever, and convulsions (seizures). After licensure (post-marketing), reported adverse events included bronchitis, cellulitis, respiratory tract infection, lymphadenopathy, thrombocytopenia, anaphylactic reaction, encephalopathy, headache, hypotonia, ear pain, apnea, cough, angiodema, pruritis, rash, fatigue and Sudden Infant Death Syndrome (SIDS).

I wonder how many parents actually are aware of these considerations, how many times these things are discussed with parents before administering these aluminum and mercury containing substances into the bodies of humans who weigh less than 20 pounds, and whether or not any parent understands the real risk:benefit ratio?  If anything the debate is most definitely NOT settled re at least some of the vaccine practices especially as a result of studies like this.  Most people do not know that there is not one single randomized, controlled trial that confirms the efficacy of the tetanus vaccine. As with most medical controversies, all his not what it seems to be.  Neither side is completely right, but information is necessary to work things out. It’s never a good idea to suppress it.
