"Common Sense Is Neither Common nor Sense"...essentially, people's personal experiences are
very limited...especially when it comes to complex matters like the choice of vaccines and treatments for a deadly airborne pathogen. We need a great deal of intelligence and established, proven, test methods brought to bear as well in order to make such critical decisions that impact life and death. IMO it is a form of 'Mental Illness' to rely on "Common Sense" when faced with such challenges....just one example.
