The Magic of mRNA Will Push Medical Advances for Everyone

mRNA is one of the first molecules of life. Although it was identified six decades ago as the carrier of the blueprint protein in living cells, its pharmaceutical potential was long underestimated. The mRNA looked unpromising: too unstable, too weak in potency, and too inflammatory.

the successful development of the first mRNA vaccines against Covid-19 in 2020 was an unprecedented achievement in the history of medicine. That success was built on iterative progress over decades, fueled by independent contributions from scientists around the world.

We fell in love with mRNA in the 1990s for its versatility, its ability to stimulate the immune system, and its safety profile: after fulfilling its biological task, the molecule is completely degraded, leaving no trace in the body. We discovered ways to exponentially improve the properties of mRNA, increasing its stability and efficacy, as well as the ability to deliver it to the right immune cells in the body. That progress has allowed us to create effective mRNA vaccines that, when administered in small amounts to humans, elicit powerful immune responses. In addition, we have established rapid and scalable processes to manufacture new vaccine candidates for clinical application in a matter of weeks. The result was the advancement of mRNA in the fight against Covid-19.

The potential of mRNA vaccines goes beyond the coronavirus. Now we want to use this technology to fight two of the world’s oldest and deadliest pathogens: malaria and tuberculosis. Worldwide, there are about 10 million new cases of tuberculosis each year. For malaria, the medical need is even greater: around 230 million malaria cases were reported in the WHO Africa region in 2020, with most deaths occurring among children under 5 years of age.

The convergence of medical advances, from next-generation sequencing to technologies for characterizing immune responses in large data sets, increases our ability to discover ideal vaccine targets. Science has also made progress in understanding how malaria and tuberculosis pathogens hide and evade the immune system, providing information on how to combat them.

The ongoing revolution in computational prediction of protein structures enables the modeling of three-dimensional protein structures. This is helping us to decipher regions in these proteins that are optimal targets for vaccine development.

One of the beauties of mRNA technology is that it allows us to rapidly test hundreds of vaccine targets. Furthermore, we can combine multiple mRNAs, each encoding a different pathogenic antigen, within a single vaccine. For the first time, it has become feasible for an mRNA-based vaccine to teach the human immune system to fight multiple vulnerable targets of a pathogen. In 2023, we plan to begin clinical trials for early malaria and tuberculosis mRNA vaccine candidates that combine known and novel targets. If successful, this effort may change the way we prevent these diseases and may contribute to their eradication.

Medical innovations can only make a difference to people around the world when they are available on a global scale. The production of mRNA is complex, involving tens of thousands of steps, making technology transfer resource-intensive, time-consuming, and error-prone. To overcome this bottleneck, we have developed a high-tech solution called the BioNTainer, a modular and transportable mRNA manufacturing facility. This innovation could support decentralized and scalable vaccine production worldwide by moving towards automated, digitized and scalable mRNA manufacturing capability. We expect the first installation to be operational in Rwanda in 2023.

We anticipate that 2023 will bring us these and other important milestones that could help shape a healthier future, one that can harness the potential of mRNA and its promise to democratize access to innovative medicines. Now is the time to drive that change.
