Vaccinations have NEVER been proposed as a one size fits all solution! You’ve missed the implications of ‘herd immunity’. By immunizing the majority of those who can be appropriately vaccinated, you protect those who for various reasons cannot.
Many of the vaccinations that exist today, prevent what used to be devastatingly common when I first started in nursing. We used frequently care for children with H-flu type B, which (if the infant survives) causes severe brain damage. We always had a few in our PICU. The vaccination has eliminated this, or at least made it’s appearance less frequent. N. Meningococcimia, can truly kill before you even realize your child is ill. One of my high school classmates pitched in a varsity baseball game, went home, ate, went to bed at his usual time and was dead by morning. It is that quick. The children who become ill in the morning or afternoon have a better chance of survival, those who are vaccinated have little to worry about. Hygiene does little to protect against Polio, chickenpox, measles, mumps, ruebella, tetanus and pertussis.
Unless you know exactly who has been handling you food each step of the way, an scrupulously scrub every raw food you eat, you can also get any of the other water borne pathogens we routinely vaccinate against. In cases of disasters such as that caused by Katrina, you REALLY want your population vaccinated, because those are the pathogens that will come and visit your neighborhood causing a second round of devastation.
