The Fastest Vaccine Developments in History

Comparing the record-breaking speed of modern vaccine creation against historical milestones.

The top 3

COVID-19 mRNA Vaccine Development Timeline: The BioNTech/Pfizer COVID-19 vaccine, 'Tozinameran', set a record by being approved for widespread use in just 337 days after the disease's identification, significantly faster than any previous vaccine. This rapid development leveraged decades of prior mRNA research and platform technology advancements.
Historic Mumps Vaccine Development Speed: Before COVID-19, the mumps vaccine held the record for fastest development, with an experimental inactivated vaccine licensed in 1948, just three years after the virus was isolated in 1945. A more effective live attenuated vaccine was licensed in 1967, completing its development in about four years.
Polio Vaccine's Rapid Public Health Impact: Jonas Salk's inactivated polio vaccine (IPV) was developed in the early 1950s, tested in 1954, and licensed on April 12, 1955, leading to a significant drop in annual U.S. polio cases from 58,000 to 5,600 by 1957. The subsequent Global Polio Eradication Initiative, launched in 1988, has reduced polio cases by over 99%.
