The first approved and released COVID-19 vaccine created by Pfeizer/BioNTech has a 90 percent efficacy rate, and it was created by an immigrant couple. The vaccine was pioneered by an immigrant couple in Germany, Dr. Ugur Sahin and Dr. Ӧzlem Tϋreci. Dr. Sahin is a Turkish immigrant that moved to Cologne, Germany from Iskenderum, Turkey with his family when he was 4. His parents worked at the Ford factory and he went on to study cancer research at a local university. Dr. Tϋreci was born in Germany, but her parents were Turkish immigrants. Her father became a doctor and used to take her everywhere with him, sparking her interest in the medical field. Together, Dr. Sahin and Dr. Tϋreci formed a pharmaceutical company, BioNTech that focused on using Messenger RNA in cancer treatment. It was this Messenger RNA technology that they used to develop the Pfizer/BioNTech vaccine in late 2020. BioNTech being a small company, they were unable to push the vaccine onto the market on their own. They ended up working with Pfizer to make the current COVID-19 vaccine a reality. The Chief Executive Officer of Pfizer, Albert Bourla, is a Greek immigrant, and Dr. Sahin and Bourla bonded quickly over their immigrant backgrounds and passion for medicine. With the assistance of Pfizer, BioNTech was able to test and develop their vaccine in time to hit the U.S. market in December 2020.  This couple of outstanding researchers is an excellent example of how much immigrants have to offer to the countries they move to!
