The first case of down syndrome wasn't recorded until the 1860's and I would argue that most deformities are caused by environmental toxins and other outside influences. Peanut allergies didn't exist until the latter part of the 20th century. Most allergies started popping up after we started pumping vaccines into people. I wasn't allergic to anything and was perfectly healthy until I was vaxxed up in the military and now I have autoimmune issues and joint pain regularly. Our bodies have always had the natural ability to protect us from outside threats since the dawn of time. We wouldn't be here otherwise.  Go take another booster.
