I'm certainly not speaking for every non vaccer. I think everyone has very individual reasons and put alot of though into why/why not.

Hep B - pfft. Babies aren't sexually active, not use iv drugs. I don't live in a high risk area either.
Tetanus - nope, don't live on a farm.
Polio - there isn't any to catch.

I don't like their bodies being LOADED with foreign stuff, especially when they are so small.

My son may or may not be on the spectrum, I'm unsure about any correlation with a particular vac and autism. It was just another reason though, not the primary one.

Other stuff I consider normal childhood illnesses and treatable. I am conscientious about keeping my kids out of general population when they aren't well. I wish other people would do the same and stop blaming non vaccers for the spread of disease.

I'm not wearing a foil hat but tbh, in the past the govt (and other govts) have been negligent and sometimes reprehensible in their actions re: immunisations.

If it wasn't for the crappy science back then HIV wouldn't have spread through the world. No foil hat - FACT.

I'm in the middle of trying to finish this housework so it's a bit disjointed. You would probably have better luck trying to understand it if you had a look in some of the past threads about this.
