Covid-19: How BioNTech Used Its Cancer Research To Create A Vaccine (CNBC)

Over a month and a half before the World Health Organization officially declared a pandemic, BioNTech CEO Uğur Şahin met with his wife, BioNTech’s co-founder and chief medical officer Özlem Türeci, and together they agreed to redirect most of the company’s resources to developing a vaccine. Up until that point, BioNTech was little-known internationally and primarily focused on developing novel cancer treatments. The founders were confident in the potential of their mRNA technology, which they knew could trigger a powerful immune response. That confidence wasn’t necessarily shared by the broader medical community. No mRNA vaccine or treatment had ever been approved before. But the couple’s timely breakthrough was actually decades in the making. CNBC spoke with Şahin and Türeci about how they, along with Pfizer, created a Covid-19 vaccine using mRNA.
