They are good on paper but you never know when something other than the vaccine is injected into you.
For example there is reason to believe small pox vaccinations were responsible for the incredibly high and unnatural HIV infection rates in the 1980's
One just never knows. I am for vaccination but at the same time am weary of them.
That may be due to just reusing of the needles which, at that point in time, wasn't regulated as much as it is now. The nurses who would give you the injections were not as educated back then (we're talking highschool diploma or Associates Degree here). From that point on, we knew that needles are a very easy vehicle for any virus to travel.
It seems like simplicity, but hey, back in the middle ages, we had no idea that washing our hands would reduce the amount of infections and deaths in hospitals either.
Those who are against it are just being conspiracy nuts. It makes sense to be cautious though.
They see a correlation between autism and vaccines and assumes it means there's a causation. Obviously, as science and our medical practices progress, so does the usage of vaccines, and so does the ability to diagnose autism.
This was a very dark period in the 21st century. We get ONE study in a medical journal where they thought to have found a link. And that was thirty years ago.
Literally every other counter-study shown no verifiable link.
But that idiot celebrity found out about that fraud study, remembered that her son with autism was vaccinated, and put two-and-two together. The result was sheets of metaphorical paper in the internet about this crackpot idea that vaccines cause autism, and now many children are dead.
If there's any evidence that non-scientists have no place in deciding scientific policies of a country, it's this.
