Their story
Why Drew Weissman matters
Weissman and Katalin Kariko discovered how to reduce unwanted immune reactions to laboratory-made mRNA.
Drew Weissman worked in United States during the Contemporary era. Today's researchers can combine powerful computers, international teams and extremely precise instruments, while also considering how discoveries affect society and the planet.
Work in immunology depends on close attention to living systems and evidence that can be compared. Drew Weissman's story shows how careful records and testable explanations can gradually improve what people know about life and health.
Key discovery or invention
Nucleoside-modified mRNA for vaccines.
Drew Weissman's central contribution was nucleoside-modified mRNA for vaccines.
The breakthrough connected observations of living things with a clearer explanation of how a body, organism or ecosystem works. Evidence could then guide better questions, comparisons and, in some cases, treatments.
Why it still matters: Modern biology and medicine continue this cycle of observation, testing, revision and careful use of evidence. Drew Weissman's work is one chapter in that continuing story rather than the final word.
Their breakthrough enabled mRNA to deliver temporary biological instructions.
