Katalin Karikó

A butcher's daughter who was demoted and defunded for decades; her mRNA work underpinned the COVID vaccines.

Katalin Karikó was born in 1955 in Szolnok, Hungary (raised in Kisújszállás). Katalin Karikó's background is described as Hungarian; emigrated to the US at 30. Growing up, the family was working class — butcher father; childhood home was a one-room adobe house without running water.

    PhD track in Szeged

    First in her family to attend university.

  2. 1985 · age 30
    Lab loses funding; emigrates~$1,000

    Flies to Philadelphia with her husband and two-year-old daughter — savings hidden in a teddy bear.

  3. 1989 · age 34
    University of Pennsylvania

    Research faculty, working on messenger RNA.
