Yeah... and I have technically been vaccinated against anthrax (for real).
The problem with many vaccines is that they do not work practically. LOL
1. They often do not offer life long protection (short duration).
2. Some like the early forms of anthrax vaccines I received (the old 5 shot series) have serious side effects.
3. Many vaccines only have a “probability” of being effective, i.e. that your immune system actually begins providing the desired protection.
4. There are ~320,000 viruses that affect mammals, and many such as the flu alone is about 1,000 various viruses. They basically just guess what virus it will be and give you the vaccine, and they often guess wrong. With the flu they guess wrong about 30% of the time.
5. Often when the vaccine is administered, it’s to late, i.e. the person has already been exposed and will get it anyway.
There are many variables.
I know this is America and we believe in a technological solution to everything. We don’t want to fix ourselves or actually deal with the problems at hand and would rather just throw money at every problem. And of course there is always a politician and business offering a magic pill, may it be scanners at airports after 9-11, hardening our facilities after HRC sat on her hands in Benghazi, more computers and textbooks as our schools fail, pills for fat people that eat bad and don’t exercise (most diabetes, high blood pressure, cholesterol gout and gird)... America has ALWAYS had a snake oil salesman offering a solution. Reality don’t work like that and of course we still have Islamic terrorism right here in the US even with our idiotic body scanners at airports, the schools didn’t get any better even with massive spending on computers and new textbooks, and ultimately the obese will still fall apart and eventually end up with much more severe medical problems. The same is true with vaccines. Yes, they are good, they have a purpose and they can help, but they are no “magical fix.”
