Vaccines and vaccines are 2 different things.
Most vaccines are good to take and to let your child have it. With some vaccines there is some doubt about if it's good to take or not.
Or if it's useful to have or to let your child have it.
Vaccines in general:
If you look back in time to when there were no vaccines. A lot of children became ill and died from diseases we no longer have to fear.
They say that some children do respond badly on a vaccine. This might be true, but difficult to prove as you can't turn back time and see what would have happened if that vaccine wasn't given to the child.
But if you look at how children are doing health wise these days and back in those days in which they weren't given vaccines.
Things are better for them now.
Some say that illnesses like ADHD and some others are caused by vaccines. Others say it's caused by all the crap they put these days in our food.
Something else that is good to be careful with, but is given very quickly is:
Antibiotics!
Because they are being given to often en to quickly we are now dealing with bacteria like:
MRSA
And that's something that is proven! Taking to quickly and to much antibiotics will make a bacteria resident to the antibiotics. That's why MRSA is so difficult to treat and we see more outbreaks of them. It's because the doctors give them to quickly.
Antibiotics will also have a negative influence on your bodies immune system. If you need them take them.
But doctors shouldn't give them as quick as they do these days.
