we didn't do them because:
a) i don't trust aluminum adjuvants
b) i don't trust the CDC
c) i DO trust the body's immune system and our modern sanitation practices as a reasonable disease prevention mechanism
d) there is not a significant risk of contracting many of the VPDs, and the ones that are still in circulation are not typically life-threatening in healthy children. they can be treated, which is not something one can say about a vaccine reaction.
e) the immune system evolved in human beings over thousands of years, in response to the bacterial and viral organisms that naturally colonize our bodies. it did NOT evolve to accept industrially manipulated organisms suspended in fetal bovine serum. just as i don't consume aspartame or high fructose corn syrup, i don't inject FBS and aluminum into my body or into the body of anyone i'm responsible for.
my only son died about five weeks ago, at 20 months of age. he did not die from a VPD or from vaccine complications; it was a very rare brain tumor which, judging by the latest research into tumor etiology, most likely had its root causes in chromosomal abnormalities or spontaneous mutations in proteins responsible for the regulation of cell death. why were those abnormalities or mutations present? environmental factors, ambient radiation, lead exposure? those things have been tested exhaustively and the results are inconclusive. i do know that generations of messing around with our immune systems (and our genes) through vaccines, fertilizers, food additives, GMOs, and antibiotics are responsible for many abnormalities in the currently circulating version of the human genome, so by forgoing vaccines for myself and my family, i'm trying not to add to the phenomenon.
man, this post got long.
