Scientists' egos are key barrier to progress, says Covid vaccine pioneer

Scientists would make swifter progress in solving the world’s problems if they learned to put their egos aside and collaborate better, according to the leading researcher behind the Pfizer/BioNTech Covid vaccine. Prof Katalin Karikó, the senior vice-president for RNA protein replacement therapies at BioNTech in Germany, endured decades of scepticism over her work and was demoted and finally kicked out of her lab while developing the technology that made the Pfizer and Moderna vaccines possible.
