"The worst comment below the piece" really touched a nerve for me as well. To me, the statement, ''Are you a doctor? No.'' case closed!" is nothing more than an admission that the people saying it have no logical argument to base their beliefs on. So to protect their feelings, they will grasp on to any trivial fact and "close" the case.

Take it from someone with an advanced degree is science (I admit, not an MD) that there are no phenomena in this universe (the risk of vaccines included) that cannot be explained to anyone with average intelligence or better within 5 to 10 minutes.

On a controversial topic such as vaccines where there is money and fuzzy concepts such as risk involved, you may need to talk to a couple of people from both sides and see what facts are common to both sides. Then you have to take the common facts and piece them together to find the "truth". You have to develop some judgement to do this but it is doable. And if something in someone argument does not make seance, then explore it further, its probably wrong. And above all, don't let someone with a degree dictate what you think. Most people are honest and well intentioned whether they have a degree or not but where there is money involved, people with degrees are hired to enforce the party line and intimidate dissenters into silence.

This many times takes the form of inducing fear followed by selling you a product to alleviate that fear. I hate to see people fall for this tactic.
