We don't want to risk any harm to our children by having them receive vaccines they don't need. Therefore it behooves us to perform a risk-benefit analysis for each vaccine, to decide if it's needed. How common and deadly is a disease and how dangerous is the vaccine?
Clearly, these things are contended and that's where the trouble lies.
Establishment medicine has its own formula for success, but is it in the best interests of the child, or is it to suit themselves? They claim honourable selflessness, but is that really true, or just a sales pitch?
In any case, the wise man finds out for himself, rather than being content with received wisdom. This is due diligence- looking deeply into a matter, rather than accepting a consensus that may be based on public relations rather than facts.
