Why Have Vaccines Become a Religion

As more people awaken to the dangers of vaccines, they discover a persistent problem vaccine safety advocates have faced for decades: talking to vaccine zealots is like speaking to a brick wall. Regardless of the evidence presented, you cannot reach them — sometimes it feels like speaking to religious fanatics unwilling to consider the "blasphemy you're spewing forth" This is deliberate, as vaccines have been enshrined as the holy water which baptizes you into the faith of Western medicine and b...
