Hungarian-born scientist Katalin Karikó believed in the potential of messenger RNA — the genetic molecule at the heart of two new COVID-19 vaccines — even when almost no one else did. 

Karikó began working with RNA as a student in Hungary. When funding for her job there ran out, Kariko immigrated to Philadelphia in 1985. Over the years, she's been rejected for grant after grant, threatened with deportation and demoted from her faculty job by a university that saw her research as a dead end. 

Through it all, Karikó just kept working. 

If new COVID-19 vaccines help life in the U.S. get back to normal next year, the nation will have many immigrants like Karikó to thank. Scientists and investors born outside of the U.S. played crucial roles in the development of vaccines from Pfizer and Moderna. It's a remarkable vindication for the argument — often made by the biotech industry — that innovation depends on the free movement of people and ideas. 

Now Karikó is a senior vice president at BionNTech, the company that partnered with Pfizer to make the first COVID-19 vaccine to get emergency authorization in the U.S. BioNTech is a company based in Germany and led by immigrants from Turkey. 

Immigrants are playing key roles in nearly every aspect of the vaccine effort in the U.S. Even the chief adviser to Operation Warp Speed, the Trump administration's vaccine distribution program, is an immigrant — Moncef Slaoui, the former head of GlaxoSmithKline's vaccines department. 

President Trump often takes credit for the record-breaking speed of vaccine development — and for "unleashing America's scientific genius," as he puts it. 

But people in the biotech industry say that American genius depends on a pool of global talent.

"We are an intellectual magnet for the best of the best from around the world," said Jeremy Levin, CEO of Ovid Therapeutics and chairman of the Biotechnology Innovation Organization, the U.S. industry trade group. 

Levin, who was born in South Africa, says high-skilled immigrants are attracted to the U.S. for its great educational institutions — and for its biotech industry that's willing to take big risks. 

"We in America are willing to take a chance," Levin said. "It is the willingness to fail in the endeavour to find a medicine that could make the difference to millions of people around the world. And that characteristic is what's drawn so many from abroad ... who are just going to have a go at it."

Levin says nearly one-third of the biotech workforce here was born outside the U.S. If you also count the children of immigrants, he says, it's roughly half. But Levin worries it's gotten harder in recent years for those people to get here. 

The Trump administration has placed more restrictions on immigrants who want to study and work in the U.S. The president says he wants to protect American jobs, and often talks about immigrants as a threat and a burden. That's how he talks about the coronavirus, as well, referring to it as the "China virus."

"It's a very racist comment," said Dr. Victor Dzau, the president of the National Academy of Medicine, a nonprofit in Washington. He's an expert on global health who was born in China. 

"We all recognize this appears to be a blame game, right? To divert your responsibility by saying that somebody else gave it to us," Dzau said. "A virus does not see any borders."

The virus has spread around the world, killing at least 1.6 million people, including more than 300,000 in the United States. Now the U.S. has developed two vaccines, and doses are being shipped around the country. 

Both use the messenger RNA technology pioneered in part by Katalin Karikó at the University of Pennsylvania. At the time, Karikó says, she applied for dozens of grants to support her work. 

"I never get the grant. All of them were rejected," she said. "Nobody was really interested in messenger RNA therapy."

As the rejection letters piled up, Karikó was demoted from her faculty position. But she persisted. "When you do science, you know, the whole wide world just does not exist. So as long as you have an idea and some experiments to do, you know, it is fun," she said. 

Karikó and her colleagues at Penn eventually solved some of the key problems that were holding the technology back. 

This week, Moderna's vaccine became the second to win an FDA advisory panel's recommendation for emergency authorization. The company, which was started 10 years ago in Boston, is also led by immigrants. 

"This country has done amazing things. And I think that a big part of that is people who bring in their own capabilities, their own dreams, aspirations," said Noubar Afeyan, Moderna's chairman. He was an early investor in the company, and also runs his own venture capital firm, Flagship Pioneering. 

Afeyan was born in Lebanon, lived in Montreal, and trained at MIT. He thinks there's a link between the immigrant experience and innovation. 

"I think of innovation as a form of intellectual immigration," Afeyan said. "You leave your comforts behind you. You face unrecognizable challenges. You take nothing for granted. You don't feel like in your new country people owe you anything."

It took scientists at Moderna and BioNTech less than a year to bring these new vaccines to market. It was an unprecedented race against time — made possible by decades of work from some of the best minds in the world.
