Trump's vaccine plan would require millions of individual shots last used decades ago

President Donald Trump has issued an executive order aimed at upending childhood vaccinations in the United States. The plan would require millions of individual shots that were last used decades ago, creating significant hurdles for implementation.

Public health experts have quickly condemned the executive order. According to reports from Washington, the most formidable obstacles to the plan involve unprecedented financial and logistical challenges that would be imposed on parents and the healthcare system.
