Temperature and hu- midity need to be monitored in real-time, with risk management systems and continuity plans in place in case of control failures. Preliminary measures to avoid temperature deviation, such as immediately re- sponsive 24/7 control centers that can access alterna- tive storage options in response to alarms, can further limit the impact of temperature excursions. Rising fill/finish and sterility needs As with most parenteral therapeutics, ensuring the sterility of the mRNA vaccines has been essential. Injectable products must be pure with no contami- nant particles that could ultimately impact patient safety. Manufacturers must carefully consider where potent ia l cont a m i nat ion cou ld ma n i fest—f rom raw materials to stoppers to other equipment—to minimize the risk. Ensuring sterility of biotherapeutics is most often achieved using sterile filtration, as this is often the only method that can suitably sterilize the product with- out affecting its stability. Typically, sterile filtration is achieved using two in-line filters during fill/finish that are placed in Grade A environments as close to the filling points (needles) as possible. In this way, the product is sterilized as it f lows through the lines to a container closure. Building technology understanding One of the biggest challenges in producing a global supply of COVID-19 mRNA vaccines was the fact that few in the biopharma industry, or those working to support development and manufacturing, had expe- rience with these types of molecules. Manufacturers that previously worked with drugs that were water-soluble had to quickly familiarize themselves with mRNA products that were encapsu- lated with lipid nanoparticles. As these technologies can be unpredictable, the potential for fill/finish con- ditions to change mRNA product characteristics had to be quickly determined. Having a thorough understanding of the poten- tial challenges likely to be encountered was vital to ensure the success of the mRNA projects. Achieving this understanding relied on the development of a strong relationship with clear communication be- tween the CDMO and the sponsor. With a relationship built on trust, important in- formation such as critical process parameters could be shared quick ly and easily between parties, en- abling rapid understanding and optimization of the processes involved. Additionally, by adopting an "own- ership mindset," many CDMOs were able to be proac- tive in deciding how the product should be processed and launched, offering advice based on their unique experience and expertise. With this approachand im- plementing dedication and discipline, critical mile- stones could be reached on time, ensuring essential vaccines reached the public at speed. Looking to the future In a feat of global research, development, and manu- facturing, the success of the COVID-19 mRNA vaccine rollout was remarkable. CDMOs quickly responded to offer their support in the production of these crit- ical products by expanding their capabilities and broadening their expertise into a new and rapidly expanding area. When examining the lessons from the early years of COVID-19's onset, it is clear that f lexibility and adapt- ability were essential for CDMOs to successfully pro- vide cold-chain and fill/finish capabilities for mRNA vaccine production. mRNA technologies will continue to expand into new therapeutic areas, further increas- ing production facility requirements. Additionally, the need for CDMOs with experience working with new and previously unfamiliar products will grow as more CGTs enter the space. By ref lecting on these lessons, manufacturers can be confident in their approach to supporting mRNA projects under pressure and be prepared for a variety of new challenges that could be predicted on the horizon.
