My oldest is 17. When I first looked into vaccine he was around 1 year (he was vaxxed at a year). I started to look into vaccine because there had been a change in the schedule (added a second MMR) and I wanted to know why. I also wanted to know how common measles, mumps and rubella were. The public health nurse who administered the vaccines could not answer. My doctor could not answer. I called the Canadian Pediatric Society and all they could say was the vaccine was safer than the disease, they could not give me prevalence figures.
That was sort of that. I had tried reasonably hard to get answers to basic questions, and health care providers had failed. I decided I was not going to vax until I could get the answers, as I could not weigh the risks/benefits. I then went about my life and did not give vaccines much thought. Oh, I would read articles and books occasionally, but nothing major. I did not have the Internet, I am not sure it even existed in 1997. I had another child in 98 - same deal. Last baby in 2002 - the Internet did exist, but I was pretty comfortable with non-vaxxing by then. I still got most info from print, and was on dial up until about 2007.
In some ways I think I had it easier.
The lack of Internet meant I couldn't research until my eyes glazed over. The lack of Internet meant there really wasn't this hatred of non-vaxxers that we see now - there wasn't a medium in which to polarize and build people up into a nasty frenzy.
I think parents now have more of an opportunity to make an informed choice, research laws, be activists if they choose - but I don't think they have it easier.
