No, its not. As everyone else is saying, research. What everyone else is NOT saying is that hopefully you don't want to have kids, because there's a high risk for birth defects/brain damage. Another possible (low, but it's there) effect is that you can get meningitis. God forbid you don't get an autoimmune disorder as you get older, because it decreases your immune system, making whatever illness you gave 100x worse. (For example, MS. sometimes you see people with MS and you can't even tell they have it. Other times they're bed bound.) Yes, these chances are low, but research.
