United States President Donald Trump has signed an executive order calling for revised childhood vaccine recommendations, including a proposal to administer routine childhood immunisations at separate medical appointments where possible. Trump has long advocated spacing out childhood vaccinations and separating the combined MMR vaccine into three individual shots. Childhood vaccines and their recommended schedules undergo extensive testing, while their safety continues to be monitored after approval. However, scientific consensus and decades of research have found no link between childhood vaccines and autism. This executive order is wrong,” Cassidy said, arguing that Trump does not have the medical expertise to make such changes.
