The difference between a pro-vaccine person and a anti-vaccine person.
Pro-vaccine person believes a drug can counteract the bad bacteria that has caused the infection. This has been going on for the last 200 years.
Anti-vaccine person believes good bacteria that counteracts the bad bacteria prevents infection in the first place. This has been going on for the last 5000 years.
That's the dilemma in a nutshell not an argument. As time has evolved the chemical/physical/emotional stress has built slowly, century after century.
Don't forget the gut has trillions of bad bacteria at any one time and your gut is 80% of your immune system. The way you counteract that bacteria is your business
and no one else's.
