President Trump has announced a plan to recommend that certain childhood immunizations be divided into five separate doses, each containing a small amount of the vaccine, which he claims would lead to a massive reduction in autism. During a news conference, he signed an executive order aimed at reshaping the federal government's approach toward childhood vaccines, suggesting that this new method would prevent children from receiving a tremendous amount of different vaccines at once. The proposed doses would be administered in six-month intervals, with the MMR vaccine specifically advised to be separated into three individual shots.
