8. 1961 Albert Sabin, a Polish-American medical researcher, introduced a live attenuated oral poliovirus vaccine, which provided a more practical and effective immunization against polio. This oral vaccine became widely used and contributed to nearly eradicating polio globally. Other live attenuated vaccines followed, including those for measles (1963), mumps (1967), rubella (1969), varicella (1995), and rotavirus (2008).
