George Bernard Shaw said this quote

“ Nothing but the natural ignorance of the public, countenanced by the inoculated erroneousness of the ordinary general medical practitioners, makes such a barbarism as vaccination possible.......Recent developments have shown that an inoculation made in the usual general practitioner's light-hearted way, without previous highly skilled examination of the state of the patient's blood, is just as likely to be a simple manslaughter as a cure or preventive. But vaccination is nothing short of attempted murder. A skilled bacteriologist would just as soon think of cutting his child's arm and rubbing the contents of the dustpan into the wound, as vaccinating it in the same. ”
