The World Health Organization (WHO) has cautioned Donald Trump against altering childhood vaccination schedules, stating such changes fly in the face of established scientific consensus. The WHO warns that spacing out vaccines increases potential risks to children’s health. This concern arises from Trump's expressed belief that vaccines are linked to autism, a claim repeatedly debunked by medical professionals. Health officials emphasize the extensive research supporting current vaccination timetables, built over decades of study. The WHO argues that any deviation from these schedules could weaken herd immunity and leave children vulnerable to preventable diseases. This represents a direct challenge by the international health body to former President Trump’s position on vaccinations.
