'Karikó’s career, however, is a story of snakes and ladders. The first snake was the late Robert Suhadolnik, who had invited her to join his biochemistry team at Temple.

When Karikó was offered a job at Johns Hopkins University, an enraged Suhadolnik sabotaged the move and reported her to the US immigration authorities for visa violation.
