mRNA Vaccines Receive Record Number of FDA Review Designations in 2023, Highlighting Expanding Role

The success of COVID-19 mRNA vaccines has underscored the significant advantages of mRNA technology in vaccine development, leading to a surge in the U.S. Food and Drug Administration (FDA) review designations for these vaccines. In 2023, the FDA granted a record nine review designations to mRNA vaccines covering eight different conditions, reflecting the agency’s commitment to advancing these products across a wider range of indications, according to GlobalData, a leading data and analytics firm.

Pfizer’s Comirnaty, approved by the FDA in August 2021, became the first mRNA vaccine on the global market, followed by Moderna’s Spikevax in January 2022. These vaccines utilize mRNA to encode a disease-specific antigen, which prompts cells to display the antigen and stimulate an immune response. This technology is estimated to have prevented 14.4 million deaths from COVID-19 globally, according to a study published in The Lancet in 2022, demonstrating the utility of mRNA vaccines in controlling pandemics.

Jasper Morley, Pharma Analyst at GlobalData, noted that since the first FDA review designation for an mRNA vaccine in 2018, a total of 25 such designations have been awarded. The pandemic spurred increased FDA activity, with five designations for mRNA vaccines across three indications in 2021. The number surged in 2023, with the FDA awarding a record nine review designations, an 80% increase from 2021, covering eight indications including human metapneumovirus, various influenza A and B subtypes, metastatic melanoma, and paramyxoviridae infections.

mRNA Vaccines Gain Increased FDA Support in 2023, Expanding Beyond COVID-19 Applications

Morley highlighted that 2023 saw nearly double the number of review designations compared to the previous peak in 2021, along with a substantial increase in the variety of associated indications. This trend indicates the FDA’s focus on promoting mRNA vaccine development beyond COVID-19. This was further confirmed by the FDA approval of Moderna’s mRESVIA, an mRNA vaccine for respiratory syncytial virus (RSV), in May 2024—the first non-COVID-19 mRNA vaccine approval. Additionally, in 2023, Moderna’s mRNA-1083 received four fast-track designations for its Phase III indications, including Influenza A and B infections and COVID-19, making it the most reviewed mRNA vaccine and expected to launch commercially before the end of 2025.

The increasing number of review designations for mRNA vaccines is a clear indicator of the FDA’s confidence in this technology. The mRNA platform offers several advantages over traditional vaccine development methods, including faster development times, higher efficacy rates, and the ability to rapidly adapt to new pathogens. These benefits were dramatically showcased during the COVID-19 pandemic, where mRNA vaccines played a pivotal role in controlling the spread of the virus and saving millions of lives.

Morley concluded that mRNA vaccines have proven their viability by successfully combating COVID-19, leading the FDA to award increasing levels of review designations since 2021. This suggests a regulatory push to develop mRNA vaccines for a variety of indications beyond COVID-19. As the FDA continues to recognize the potential of mRNA technology, we will likely see more mRNA vaccines entering the market for a wide range of diseases.

Advancements in mRNA Technology Expected to Drive Pharmaceutical Innovation and Industry Investment

The impact of these developments extends beyond public health. The rapid advancement of mRNA technology is also likely to influence the broader pharmaceutical industry, encouraging more investment in innovative research and development. Companies are expected to explore new applications for mRNA technology, potentially leading to breakthroughs in the treatment of cancers, genetic disorders, and other complex diseases.

The collaboration between pharmaceutical companies and regulatory bodies has been a crucial factor in the success of mRNA vaccines. The FDA’s proactive approach in awarding review designations and fast-tracking approvals has facilitated the rapid development and deployment of these vaccines. This collaborative model is expected to continue, fostering an environment where innovative treatments can be developed and brought to market more efficiently.
