The Untold Journey of the Pfizer BioNTech COVID-19 Vaccine

Chapter 1: The Couple Behind the Vaccine
The remarkable journey of the COVID-19 vaccine can be traced back to two dedicated scientists whose love story began in a cancer research lab. Dr. Ugur Sahin and Dr. Özlem Tureci, both from Turkish immigrant backgrounds, united their passion for cancer research and opened a modest lab with limited resources. Their years of commitment to understanding cancer ultimately led to the groundbreaking development of a vaccine that has saved countless lives during the pandemic.
Many, including myself, were initially skeptical about how such an effective vaccine could emerge so rapidly. Were these vaccines merely a ploy by pharmaceutical companies to make profits? After diving into Joe Miller’s insightful book, "The Vaccine: Inside the Race to Conquer the Covid-19 Pandemic," my questions found clarity. This book is essential for those who harbor doubts about vaccines.
> The Couple Behind the Vaccine's Development
Research scientists, Dr. Ugur Sahin and Dr. Özlem Tureci, first crossed paths at a cancer research facility in Germany. Their shared upbringing in immigrant Turkish families forged a strong connection, further solidified by their mutual dedication to cancer research. For years, their tireless efforts went largely unnoticed until the pandemic thrust them into the limelight as the creators of the world’s first COVID-19 vaccine, raising the question—was this a spontaneous achievement or the result of years of groundwork?
Despite their monumental success with the mRNA vaccine in collaboration with Pfizer, the couple remains grounded. They continue to live in a modest two-bedroom apartment, opt for cycling over car ownership, and maintain a low-profile lifestyle. Their humility stands in stark contrast to the skepticism surrounding the vaccine's commercialization, showcasing a deep dedication to their work that has helped millions escape the pandemic's grip.
As of September 2022, over 5.35 billion people globally have received a COVID-19 vaccine—approximately 69.7% of the world's population.
What It Took to Create the Vaccine
Contrary to popular belief, mRNA technology isn't a recent innovation. Research involving mRNA dates back to the 1970s, primarily in the context of cancer therapies. In 1990, Jon Wolff, a pioneer in gene therapy, found that when mRNA was injected into mice, it could produce the intended proteins. Although this was a significant revelation, it didn't garner much attention from the scientific community due to the inherent instability of mRNA compared to DNA.
The fragile nature of the mRNA molecule posed significant challenges to researchers. When Ugur and Özlem began their work, they implemented rigorous measures to protect the mRNA's stability, knowing that even minor contaminants could compromise their efforts. Their quest for a protective shield to ensure the mRNA's safe delivery into cells was no easy feat.
After extensive experimentation, they discovered that encapsulating the mRNA in a lipid formulation provided the necessary protection during transport. This breakthrough was crucial for the mRNA’s stability, allowing it to avoid degradation within the body.
But how does mRNA function? Prior research indicated that once mRNA reaches the lymph nodes, dendritic cells activate the immune system. This realization inspired Ugur to pivot his lab's focus from cancer research to developing a COVID-19 vaccine when the pandemic emerged. This decision was met with initial skepticism from his team, as their lab had never commercialized a product before.
One of the immediate hurdles was addressing the mRNA's fragility. After countless trials, Ugur and Özlem determined the optimal mRNA-to-lipid ratio, which was pivotal for the vaccine's efficacy. With this breakthrough, Ugur felt confident in their ability to create a vaccine targeting the SARS-CoV-2 virus.
Their next challenge was finding a pharmaceutical partner capable of scaling the vaccine’s production and distribution.
Seeking Partnerships
Before the pandemic, Ugur had spent years presenting his lab's mRNA cancer research to potential investors, but the responses were often lukewarm. The couple faced significant obstacles in both Germany and the U.S., where immigrant-owned companies rarely received attention from investors.
When BioNTech recognized the potential of their mRNA technology for a COVID-19 vaccine, they initially approached Pfizer. However, Pfizer hesitated, doubting that a cancer research biotech with no commercial products could successfully deliver a vaccine. Disheartened, Sahin and Tureci sought partnerships with other pharmaceutical companies but faced similar rejections.
It wasn't until the pandemic intensified that Pfizer reconsidered its stance and reached out to BioNTech. After several weeks of discussions, they formed a partnership, with BioNTech leading the scientific development while Pfizer managed clinical trials and distribution.
The rest, as they say, is history.
Bottom Line
The rapid deployment of the COVID-19 vaccines was not mere luck; it was the culmination of decades of research and dedication. For those skeptical of the pandemic or the vaccines, it’s time to reevaluate your position and engage with the science that underpins these vital medical advancements.
Debunking Common Myths About the Pfizer BioNTech COVID-19 Vaccine
mRNA is a new technology — FALSE
This technology has been in development since the 1970s; its application in COVID-19 vaccines is what is novel.
mRNA alters your DNA — FALSE
mRNA does not contain any components that alter DNA.
mRNA vaccines skipped clinical trials — FALSE
Pfizer's phase three clinical trials began in July 2020, with results published in December 2020, involving over 46,000 participants globally.
mRNA has significant side effects — FALSE
The largest real-world study indicates that Pfizer/BioNTech's vaccine is safe and associated with fewer adverse effects than COVID-19 infection in unvaccinated individuals.
