British scientists are at the forefront of developing a vaccine against future deadly pandemics, aiming to have it ready within 100 days of an outbreak. The new state-of-the-art facility, located in Porton Down, will enhance pandemic preparedness and create prototype vaccines to combat “Disease X” when it emerges. Collaborating with academia and industry, this site is the only research facility in the UK equipped to develop a vaccine from start to finish. So, what exactly is Disease X, and why are British scientists focusing on an unknown disease? Here’s everything you need to know.
Disease X is a hypothetical pathogen that is currently unidentified. It was named by the World Health Organization (WHO) in 2018 to ensure their planning could adapt to any potential disease. In their list of nine priority diseases, the WHO states that Disease X represents the understanding that a severe global epidemic could be triggered by a pathogen currently unknown to affect humans. Professor Dame Jenny Harries, the head of the UK Health Security Agency (UKHSA), stated that the goal is to prepare for the unknown. By conducting the necessary research and development in advance, they aim to prevent or respond swiftly to a potential pandemic.
The top-secret Porton Down laboratory, situated within the Wiltshire countryside near Salisbury, has a controversial history. It gained attention when a nerve agent was used in the attempted assassination of Sergei Skripal, a former Russian intelligence officer turned British double agent. Established in 1916 after Germany’s use of chlorine gas, the facility initially focused on chemical research and later expanded to biological weapons. However, today the lab has shifted its focus to developing vaccines and therapeutics to tackle emerging diseases like Disease X.
As scientists have consistently warned, bird flu is the most likely candidate to trigger the next pandemic. The threat of recombination, where a human is co-infected with both avian flu and human flu, poses a significant risk. Zoonotic transmission, where an animal virus or bacteria jumps to humans, has also been a concern in disease emergence. Additionally, some have suggested that Disease X could arise from biological mutations, accidents, or even terror attacks, catching the world off guard and spreading rapidly. Furthermore, increasing antibiotic resistance among bacteria could potentially lead to Disease X.
To prepare for Disease X, countries worldwide have pledged $1.5 billion, with the UK government contributing £160 million. The Gates Foundation and the Wellcome Trust have also invested in research targeting Disease X. The expansion of laboratory space at Porton Down has allowed for increased capacity and resources to focus on the most dangerous viruses. The number of scientists working on vaccines has grown by 50% since 2020, with greater technological investment. UK scientists can now test 3,000 samples weekly, compared to just 100 before the Covid-19 pandemic.
The collaboration at Porton Down is crucial because global migration and climate change are increasing the threat of disease emergence. As humans and animals move closer together, the risk of pathogen transmission grows. Global warming also enables pathogens carried by vectors like mosquitoes and ticks to appear in new locations, including the UK. Professor Sir Andrew Pollard, chairman of the Joint Committee on Vaccination and Immunisation, highlights the impact of climate change and urbanization on disease transmission. By expanding research facilities like Porton Down, scientists can study potent viruses and bacteria and develop vaccines to combat diseases like Crimean-Congo haemorrhagic fever.
In conclusion, British scientists are leading the charge in vaccine development to combat future deadly pandemics. With the new super lab in Porton Down, they aim to be prepared for Disease X and other emerging diseases. The research conducted will help prevent and respond to potential pandemics swiftly. By investing in advancements and resources, scientists are working towards a safer and healthier future for all.
