A US vaccine expert attributes the surge in measles cases in Texas, the highest in over 30 years, to policy failures at both state and federal levels. Dr. Peter Hotez cited nonmedical exemptions in 18 states, potential federal limitations on vaccines, and a lack of effective vaccine advocacy as contributing factors. Texas health officials are urging parents to ensure children are vaccinated, while Hotez warns of a resurgence of preventable diseases if coverage does not improve and misinformation is not countered.
