Let’s talk about herd immunity, since the concept is being used to pit parents against parents.
Herd immunity is, “The resistance by a group to attack by a disease by which a large proportion of members are immune, thus lessening the likelihood of a patient with a disease coming into contact with a susceptible individual.”
It is a theory (see Hamer, 1906 –http://courses.washington.edu/b578a/readings/fine1993.pdf).
The only gold standard for comparison is Natural Immunity.
Being “fully vaccinated” does not confer permanent immunity – results vary. The many boosters added over time to the schedule demonstrate this, and growing evidence shows that repeated vaccination may hamper natural immune response at least in the case of flu vaccines (http://www.ncbi.nlm.nih.gov/pubmed/21880755).
Vaccination is claimed “effective” if one (of the many) immune cells shows an increase after injection. That’s all. No scientific study / measurement is made of actual disease prevention. Just an increase in antibodies. What happens to the delicate balance of the immune system?
“If vaccination does not confer solid immunity against infection to all recipients, the threshold level of vaccination required to protect a population increases.”http://cid.oxfordjournals.org/content/52/7/911.full
Herd immunity is being used to push the widespread, universal human consumption of vaccines. The overall summary of marketing strategy goes something like this: If the product does not work, add more (boosters). And if that does not work, ask more people to use the product. If that does not work, try to guilt individuals into taking the injection for the betterment of society.
A very important point of clarification before this is taken out of context. We have stated that, “Vaccination is claimed “effective” if one (of the many) immune cells shows an increase after injection. That’s all. No scientific study / measurement is made of actual disease prevention”… I want to be sure to clarify that I meant that no scientific study is made of actual disease prevention AS PART OF CLINICAL TRIALS TO GET PRODUCTS TO FDA APPROVAL/MARKET. Clinical trials use only surrogate markers (usually the induction of a chosen antibody in healthy volunteers as compared to another vaccine as placebo). THERE ARE MANY SCIENTIFIC VACCINE EFFICACY STUDIES, of variable quality, that have been performed over the years after vaccines enter the market.
