In my opinion, if you vaccinate your children or your self, that is Bodhisattvic activity, serving the needs of other and relieving them from potential harm and suffering.
And if you do not vaccinate, unless it is due to medical reasons or lack of opportunity, you put others and your self at risk, potentially causing harm and suffering, and maybe nurturing self-centeredness and delusion. What self do you protect? How? What is protecting? How far or narrow is self? What is being the Bodhisattva you are?
Here is an article that gives some details regarding this matter:
"Almost 8,000 cases of pertussis, better known as whooping cough, have
been reported to California's Public Health Department so far this
year. More than 250 patients have been hospitalized, nearly all of them
infants and young children, and 58 have required intensive care. Why is
this preventable respiratory infection making a comeback?
In no small
part thanks to low vaccination rates...
The conversation about
vaccination has changed. In the 1990s, when new vaccines were
introduced, the news media were obsessed with the notion that vaccines
might be doing more harm than good. The measles-mumps-rubella (MMR)
vaccine might cause autism, we were told. Thimerosal, an ethyl-mercury
containing preservative in some vaccines, might cause developmental
delays. Too many vaccines given too soon, the stories went, might
overwhelm a child's immune system.
Then those stories
disappeared. One reason was that study after study showed that these
concerns were ill-founded. Another was that the famous 1998 report
claiming to show a link between vaccinations and autism was retracted by
The Lancet, the medical journal that had published it. The study was
not only spectacularly wrong, as more than a dozen studies have shown,
but also fraudulent. The author, British surgeon
Andrew Wakefield,
has since been stripped of his medical license.
But the
damage was done. Countless parents became afraid of vaccines. As a
consequence, many parents now choose to delay, withhold, separate or
space out vaccines. Some don't vaccinate their children at all. A 2006
study in the Journal of the American Medical Association showed that
between 1991 and 2004, the percentage of children whose parents had
chosen to opt out of vaccines increased by 6% a year, resulting in a
more than twofold increase.
Today the media are covering the
next part of this story, the inevitable outbreaks of vaccine-preventable
diseases, mostly among children who have not been vaccinated. Some of
the parents who chose not to vaccinate were influenced by the original,
inaccurate media coverage..."
