Dr. Katalin Karikó, a Hungarian biochemist, and Dr. Drew Weissman, an American physician-scientist, have been honored with the prestigious 2023 Nobel Prize in Physiology or Medicine. The Royal Swedish Academy of Science recognized their groundbreaking contributions to the field of nucleoside base modification, which enabled the development of highly effective mRNA vaccines against COVID-19. Dr. Karikó’s win is particularly significant as she is only the thirteenth woman to receive this prestigious award. This acknowledgment sheds light on the pivotal role mRNA vaccines played during the pandemic, showcasing their vast potential in transforming the future of healthcare.

Messenger RNA (mRNA) is a type of molecule responsible for relaying instructions from DNA to a cell’s cytoplasm, where proteins are synthesized. In the late 1980s, scientists realized that mRNA could revolutionize vaccine development if certain challenges could be overcome. The concept involved injecting modified mRNA into the body, which would instruct cells to produce specific proteins. By doing so, the immune system would recognize these proteins as foreign and mount an immune response, preparing the body to combat future encounters with the same protein. This approach was especially relevant in targeting viral proteins, such as the spike protein found in SARS-CoV-2.

However, for this idea to be successful, the mRNA would need to survive and reach cells within the body. Dr. Karikó and Dr. Weissman commenced their collaboration in the late 1990s, setting out to unravel the complexities associated with delivering mRNA into living organisms and achieving an optimal immune response. Numerous studies were published by them and their scientific counterparts up until 2004, shedding light on the necessary steps involved in this process. However, a significant obstacle remained: the immune system recognized synthetic mRNA as a foreign substance, triggering its elimination response. That is when Dr. Karikó, Dr. Weissman, along with Michael Buckstein and Houping Ni, published a seminal study in 2005, offering an explanation. They discovered that while synthetic mRNA remained unchanged, the cells’ mRNA underwent chemical modifications, making it indistinguishable from the body’s own mRNA. This breakthrough opened the doors to unlocking how foreign mRNA could enter the body’s cells without raising alarm bells.

Further studies published by the duo set the foundation for utilizing mRNA as a platform to develop a new kind of vaccine. Then, in 2020, the world was struck by the COVID-19 pandemic, and mRNA vaccines emerged as a game-changer, significantly lowering the death toll. However, the humanitarian triumph of these vaccines was, unfortunately, overshadowed by the rise of vaccine nationalism, which hindered global cooperation and distribution efforts.

The advantages of mRNA vaccines are manifold. The manufacturing process is swift, with scientists being able to begin production in the morning and yield enough vaccines for testing by evening. This efficiency expedites the development and distribution of vaccines, contributing to the punctual response during critical times. Additionally, scientists are currently exploring the potential use of mRNA vaccines to combat influenza, dengue, as well as certain cancers and autoimmune diseases. The transformative power of mRNA in tackling these diseases is still being researched and holds immense promise for the future of medicine.

The awarded Nobel Prize in Physiology or Medicine to Dr. Karikó and Dr. Weissman underscores the significance of their discoveries concerning nucleoside base modification, enabling the development of highly effective mRNA vaccines against COVID-19. This groundbreaking research, pioneered in the 1980s and brought to fruition during the pandemic, has revolutionized the field of vaccine development. As we look towards the future, we can anticipate the continued advancements in mRNA technology, which will lead to even more innovative solutions in the fight against diseases that have plagued humanity for centuries.
