Scientists suggest that it is very much possible for autism to develop in the womb during pregnancy. However, most of the symptoms of autism start to appear after birth. As a result, it becomes hard to diagnose autism from a very early age.

#25 There’s No Link Between Autism and Vaccines

Reportedly, 20 percent of the population of the USA believe that vaccines are one of the main causes of ASD or Autism Spectrum Disorder. However, this claim is totally incorrect. There is no relation between vaccines and autism. Matter of fact, over dozens of researches on this topic, have suggested that vaccines are safe, effective, and vital to fight against particular diseases.

On top of that, vaccines don’t cause autism or any type of disorder. In fact, we don’t even know what the main reason behind autism is. Right now, we know that there is no single factor that is responsible for autism. Rather, a combination of various genetic, non-genetic, and environmental factors can influence in autism. So, you should vaccinate your kids.


As from the information above, it is clear that autism has no cure as of right now. However, if early diagnosis is possible, then it can greatly improve the condition of the individuals identified with ASD.
