What failed

Through the 1990s her grant applications for mRNA research were rejected repeatedly. With no funding coming in, the University of Pennsylvania demoted her and cut her pay, and she spent more than two decades in low-ranking non-tenured posts. In 2013 she was pushed out after 24 years.

What happened next

She kept doing the same work anyway — in her words, working like nothing happened — joined BioNTech, and the modified-mRNA method she developed with Drew Weissman became the basis of the COVID-19 vaccines. Nobel Prize in 2023.

The point

She did not persist because she was winning. She persisted because the experiment was still there to be done.

The sequence

3 documented failures, shown with the successes in between. Every entry carries its own source — the wins are part of the record, and leaving them out is how these stories get distorted.

  1. 1989

    Joins the University of Pennsylvania to work on messenger RNA.

  2. 1995

    Taken off the track to full professorship and demoted, after her grant applications are turned down again and again.

  3. 1995

    Her bosses judge the mRNA work unproductive. She keeps doing it.

    Meets the immunologist Drew Weissman, newly arrived at Penn.

  5. 2005

    The paper that would underpin the mRNA vaccines is desk-rejected by Nature.

    It runs in a smaller journal instead. Building synthetic mRNA with chemically modified bases almost abolishes the inflammatory reaction it had set off in immune cells.

  7. 2013

    Pushed out of Penn after twenty-four years. In her own words, kicked out and forced to retire.

  8. 2023

    The Nobel Prize in Physiology or Medicine, shared with Weissman, for the discovery the demotion was meant to stop.
