  4. A BREAKTHROUGH IN SCIENCE Jonas Salk developed inactivated (killed-virus) vaccine Formalin preserved virus shape for immune training Safety-first design → minimized vaccine-caused illness Vaccine production = science + industrial discipline

  5. TRIALS, TRUST & CIVIC COOPERATION 1954: largest field trial in history (1M+ children) Independent evaluation separated science from hype March of Dimes funded labs & logistics Nurses, schools, and parents became partners in progress

  6. LESSONS IN SAFETY & OVERSIGHT Early manufacturing error caused outbreaks → program paused Transparent investigation rebuilt trust Led to stricter biologics regulation & quality control Proved: safety is structure, not a promise

  7. LEGACY & GLOBAL IMPACT Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis vel dolor ante. Nullam feugiat egestas elit et vehicula.
