Designing Vaccines: The Role of Artificial Intelligence and Digital Health, Part 1

According to the founder and executive chairman of the World Economic Forum, Klaus Schwab, the fourth industrial revolution began in the 21st century and is characterized by an unprecedented development and exponential growth of a high-technology industry transforming society at every level (1–4). In particular, healthcare systems are evolving rapidly to adapt to the new reality. According to Forbes, the main technologies currently shifting the paradigm of medical research are artificial intelligence (AI) and machine learning (ML) (5), both defined…

The Next COVID Challenge: Building an Arsenal of Vaccines

For months, international partners have pressured the United States about intellectual property (IP) concerns and access to SARS-CoV-2 vaccines. As the country emerges from the worst of the pandemic, President Joe Biden now has an opportunity to shift his administration’s focus to realizing its longstanding promise of making the United States “the arsenal of vaccines for the world” (1). However, the country cannot accomplish that goal just by exporting mRNA vaccines and waiving IP protections. The current generation of vaccines…

High Virus-Titer–Producing Cell Lines for Bioproduction

Antiviral vaccines are essential for preventing epidemic disease. However, production of them often is limited by low-yielding manufacturing processes. Similarly, the development of gene therapies is constrained during the production of adenoassociated virus (AAV) delivery platforms for gene transfer. To address the need for efficient viral synthesis to quicken the pace of bioproduction, ATCC used CRISPR/Cas9 genome-editing technology to develop STAT1 and BAX knockout (STAT1 BAX KO) cell lines to produce high-titer viral stocks. Three cell lines optimized for virus…

eBook: mRNA — Revisiting a Technology That Has Rocketed into Success

At the end of 2018, BPI published its first eBook about mRNA drug products — and quite a lot has happened since then! Our initial report highlighted companies working on mRNA therapeutics for cystic fibrosis, heart disease, and cancer, as well as vaccines. The latter approach took off in 2020 with the advent of SARS-CoV-2 and the COVID-19 pandemic, and in a stunningly short time, the biopharmaceutical industry has learned much about manufacture, formulation, product design, and distribution of mRNA…

How Capacitance Measurement Can Improve Viral Vector and Virus-Based Vaccine Production

With the increasing development of viral vector and virus-based vaccines, technologies that help to manufacture and scale up these types of vaccine quickly and cost-effectively have become more critical. By accessing this special report from Aditya Bhat, a capacitance technology expert at Aber Instruments, you will find out how in-line capacitance measurement can produce a detailed fingerprint of cell culture processes and how that can benefit vaccine production. From case studies involving baculovirus, AAV, and measles, you will discover why…

eBook: Vaccines — COVID-19 Invigorates a Stagnant Industry

The SARS-CoV-2 novel coronavirus has galvanized what was a stagnant and oligopoly-run vaccine industry. In this inaugural BioProcess Insider eBook, the first of four to be published in 2021, founding editor Dan Stanton explores economic and technical conditions that until now have hampered innovation in vaccine development and discouraged market entry for emerging biotechnology companies. Leveraging commentary from vaccine industry experts and analyzing the range of emerging vaccine modalities, Stanton surveys how industry responses to the COVID-19 pandemic are fostering…

Exciting Starts for New Players and Platforms: Nucleic-Acid Vaccines Prepare for Their Commercial Debut

Although vaccine platforms based on messenger RNA (mRNA) are enjoying the limelight in the wake of emergency authorizations of products from Pfizer–BioNTech and Moderna, DNA vaccines are poised to make their own commercial debuts soon. The World Health Organization (WHO) reports that six of the 48 candidate vaccines against SARS-CoV-2 that remain in clinical trials are DNA-based products, as are 14 others in preclinical study (1). I spoke with Hong Jiang (cofounder and chief operating officer of Aegis Life, Inc.)…

Cold-Chain Validation: Emerging Vaccines for COVID-19 and Beyond Require More Extensive Evaluation

In the wake of fast-track approvals for Pfizer’s and Moderna’s respective SARS-CoV-2 vaccines, now begins the largest immunization campaign in world history. Its success will depend not only on the products’ safety and efficacy, but also on several mass-distribution programs requiring significant cold-chain infrastructure. The public has become acutely aware of the Pfizer vaccine’s demanding cryostorage specifications, generating considerable anxiety about how mass distribution will happen. Behind the scenes, however, cold-chain engineering companies such as Modality Solutions have worked alongside…

Enhancing Vaccine Platforms: Computational Models Accelerate Development, Manufacturing, and Distribution

Pandemics such as the current COVID-19 outbreak pose tremendous healthcare and economic challenges. Vaccines hold promise for controlling pandemics; however, substantial challenges come with pandemic-response vaccine development, manufacturing, distribution, and administration. To address those now, many companies are using rapid-response vaccine-production platform technologies. Computational modeling tools could help further accelerate development of those technologies, increase production and distribution efficiencies, and reduce costs and risks once vaccine platforms are fully developed and validated. To those ends, a set of modeling methodologies…

Advanced Analytics to Accelerate Development of Genetic Vaccines

Biopharmaceutical companies are racing to develop vaccines that mitigate the COVID-19 pandemic, taking a wide range of vaccine-development approaches that include traditional modalities and cutting-edge technologies based on DNA and RNA. Vaccine developers are leveraging robust manufacturing concepts and integrated processes to shorten timelines. Advanced analytics also are playing a critical role in ensuring the safety and efficacy of those emerging vaccines. A New Wave of Vaccines Vaccines based on attenuated viruses entail development timelines ranging from four years to…
