Thanks for sharing Dreamcatcher. Haven't read yet, so can't comment on article. But re 'side effects' of vaccination, they can include some pretty nasty chemicals in vaccines(thimerosal, formalin, for eg), not to mention the diseases themselves - this is especially so for combo vaccines - like 'triple antigens' for humans. Not sure if they do that for horses, as aside from 10-yearly tetanus & strangles when they're young, it's not common for Aussies to vaccinate horses.
**FYI, I am NOT anti-vacc. Long story short(I'll try!), I knew there were side effects, so I started researching when I first got pregnant, in order to learn how I could counter those side effects in my baby when she was immunised. It was a very frustrating subject to study, because while there was HEAPS of info to be had, there was precious little *objective & unbiased* research/evidence. It seemed like there were the 'hippies'(nothing against hippies, just way to explain!) on one side, saying all vaccines and docs who proscribed them were evil, and the 'rednecks' on the other side saying any & all claims from 'hippies' were idiotic & totally unfounded. In addition, most people on either side that I asked(naturopaths, doctors for eg) would basically fob me off as a complete idiot for even asking the questions! I did find some good info though, and even some open minded medical doctors to help me learn better. I ended up not vaccinating my babies at all, until they were about 3yo, when they had most of the usual ones... one at a time.
