Introducing VDEC: Unraveling the Mysteries of Disease X and Advancing Vaccine Research

The Search for Disease X: U.K. Establishes Vaccine Research Center

Introduction

On August 7, 2023, the term “Disease X” started trending on social media, causing some concern among the public. However, Disease X does not refer to a specific virus or pathogen but instead represents the unknown threat of a future pandemic. The United Kingdom has taken a proactive approach to tackle this potential threat by establishing the Vaccine Development and Evaluation Centre (VDEC), located at the U.K. Health and Security Agency (UKHSA) Porton Down campus in Wiltshire. The goal of VDEC is to develop vaccines that can save lives and mitigate harm from vaccine-preventable diseases, including emerging pathogens with pandemic potential.

The Significance of Disease X

The concept of Disease X is not new. The World Health Organization (WHO) added Disease X to its Blueprint list of priority diseases in 2018, long before the onset of the Covid-19 pandemic. The inclusion of Disease X highlighted the need for accelerated research and development to address new and unknown infectious threats. The WHO’s foresight was evident, as both the Middle East respiratory syndrome coronavirus (MERS-CoV) and severe acute respiratory syndrome (SARS) were already outbreak-causing diseases belonging to the same family as the current Covid-19 virus.

Preparing for Future Outbreaks

The politicization of the origins of SARS-CoV-2 has obscured the fact that viruses and other pathogens frequently jump from animals to humans, leading to outbreaks and pandemics. Examples include the original SARS and MERS-CoV outbreaks, as well as the H1N1 influenza pandemic in 2009. The origins of SARS-CoV-2 are still under investigation, but scientific evidence suggests it originated from an animal source before spreading to humans.

To prevent and prepare for future outbreaks, it is crucial for society to enhance its surveillance systems, track viral activity, and understand the impact of climate change on the movement and habitat of animals. Additionally, research efforts must be prioritized to develop vaccines and treatments for known pathogens, such as avian influenza. This proactive approach will not only provide potential solutions for existing threats but also better prepare for the emergence of unknown pathogens.

The Role of VDEC

The newly established VDEC in the UK will play a vital role in advancing vaccine research and development capabilities. With over 2,800 square meters of laboratory space at Porton Down, VDEC will bring together more than 200 scientists working on approximately 100 different projects. The center will focus on various areas, including testing vaccine efficacy, developing a vaccine against Crimean-Congo haemorrhagic fever, and researching vaccines against influenza.

In addition, VDEC will dedicate efforts to prepare for Disease X scenarios by developing immunological assays to rapidly screen potential treatment candidates when faced with a newly emerging pathogen. The center’s collaboration with the Defense Science and Technology Laboratory facilities highlights the importance of aligning national security and public health objectives.

The Road to Preparedness

Although VDEC is a significant step towards addressing unknown pathogens, it is not the sole solution. Society must continue to invest in surveillance systems, research capacity, and manufacturing infrastructure to enhance outbreak preparedness. Furthermore, ongoing research on known and existing pathogens will contribute to broader discoveries and a better understanding of potential future threats. It is imperative that political and business leaders take responsibility and prioritize proactive measures rather than resorting to blame and excuses after an outbreak occurs.

Conclusion

The establishment of VDEC is a commendable effort by the United Kingdom to prepare for the unknown threat of Disease X. The center’s focus on vaccine development and evaluation, as well as its collaboration with national and international partners, demonstrates a commitment to mitigating the potential harm of emerging pathogens. However, it is essential for society as a whole to invest in enhancing surveillance, research, and manufacturing capacity to effectively address both known and unknown infectious threats. Proactive measures and preparedness are key to averting future pandemics and ensuring the health and safety of humanity.
