Advancements in Health

Progress in health often goes unnoticed because it is measured by events that did not happen, like smallpox infections due to vaccinations. The extension of human lifespan, doubling in the past century, has largely been a result of incremental innovations such as vaccines. Childhood mortality rates have significantly decreased, with more children surviving into adulthood. Innovations like pasteurization and clean drinking water have played crucial roles in improving overall health.
