One of the most important inventions in human history is vaccines. Eradicating smallpox, preventing public health crises, and lowering mortality rates, vaccines have revolutionized global health. With the latest mRNA vaccine technology ushering in a new era of vaccinology, there has been a renewed interest in vaccine development for researchers.
Since the smallpox vaccine was first introduced in 1796, researchers have been innovating and updating vaccines to strengthen immunity. In recognition of National Immunization Month, we reviewed some of the key vaccine innovations throughout history that protected people of all ages against serious diseases.
