Here is a big problem with anti-vax. If you believe that vaccination cause autism then you must explain why some who have never had a vaccination still have autism.
In my lifetime I have known those who had polio and have saw the deformity of it. Through vaccination I have also seen polio be cast to the sideline. I no longer see people who had polio as a child or those who have it today as an adult.
Research has proven that autism happens during gestation, but the anti-vaxxers choose to ignore that fact. It’s sad that they’d rather have a dead child than an autistic one, by their logic. Rather others be dead or disabled, too.
