Risk aversion, or society aversion?

Saw one of my partner’s patients today, who had presented him with a vaccination schedule for her soon-to-be-newborn-baby.  Because she’s "concerned for her baby’s health" and she’s "unsure of the safety of these vaccines," the schedule started at one year of age (no vaccines prior to 12 months) and seemed to somewhat randomly choose the vaccinations, combinations and number of doses.
This situation prompts, as many do, a variety of reactions in me, but the one I’ll focus on is how much our penchant for total risk aversion has clouded our reason.  I want to believe that if there were some graphical depiction of the chance that vaccines will help her child vs. the chance that vaccines will harm her child she would come around.  However, it’s not all about underestimating perceived benefit…I worry that it’s more than that. 
I worry that vaccines are seen as something that we all do for each other, but the harm that can come from a vaccine reaction only affects a single individual.  I think these people are voting with their little individualist feet, and deciding to forgo society’s benefit to avoid harm to their child – without needing to consider the magnitude of the individual risks.  We increasingly don’t care about each other in our community (writ however large is appropriate) – we only care about our individual well-being and success.  I wonder if this is how it felt to live in the Roman Empire, just before the fall…
