People are skeptical of all the reports that children regressed shortly after receiving a vaccine. These oddly timed regressions have led many non-supporters to believe that vaccines cause children to develop disabilities. If I were a parent, I too would want the best for my child and be concerned about these regressions, but you have to look at both sides of the story and understand the medical outcomes. According to health professionals (Ethos) in the documentary Vaxxed, vaccines have in no way caused these regressions in children (Vaxxed). Overall, vaccines are a safe and important part of a child's treatment.
