As former President Donald Trump hints at considering a ban on certain vaccines and removing fluoride from drinking water, pediatricians and health experts express significant concerns. Trump, endorsing Robert F. Kennedy Jr.'s anti-vaccine views, may influence vaccination rates and public health guidelines, leading to fears of outbreaks of preventable diseases. Despite decades of evidence supporting vaccines and fluoride's role in oral health, misinformation and politicization of these issues continue to threaten public health strategies, particularly for children. With public health recommendations at stake, experts warn of potentially dire consequences for child well-being.
