Oxford Scientists Initiates First Human Trials For Deadly Nipah Virus Vaccine


In a groundbreaking initiative, researchers at the University of Oxford in the United Kingdom have commenced the first-in-human vaccine trials for the deadly Nipah virus. This initiative is a significant step forward in addressing the severe impact of the virus on various Asian countries, including India. The trials will be conducted on 51 individuals aged 18 to 55 and are led by the Oxford Vaccine Group.

The ChAdOx1 NipahB Vaccine: A Ray of Hope

The experimental vaccine, named ChAdOx1 NipahB, aims to combat the Nipah virus, a highly lethal disease with a fatality rate of approximately 75%. The Nipah virus has been responsible for outbreaks in several Asian countries, such as Singapore, Malaysia, Bangladesh, and India. Notably, a recent outbreak occurred in Kerala in September of the previous year.

Understanding Nipah Virus Transmission

Scientists have identified fruit bats as carriers of the Nipah virus. Transmission can also occur through contact with infected animals, such as pigs, or from person-to-person through close contact. Given the severity and rapid transmission of the virus, urgent research is deemed necessary.

Nipah Virus: A Priority Disease Recognized by WHO

Belonging to the paramyxovirus family, similar to measles, the Nipah virus is classified by the World Health Organization (WHO) as a priority disease requiring immediate attention and research. Despite the first outbreaks occurring 25 years ago in Malaysia and Singapore, there are currently no approved vaccines or treatments for Nipah virus.

Nipah Virus: A Priority Pandemic Pathogen

Due to its high mortality rate and mode of transmission, Nipah virus is identified as a priority pandemic pathogen. The vaccine trial marks a crucial milestone in the quest for a preventive solution, not only to thwart local outbreaks but also to prepare for potential global pandemics.

CEPI’s Role in Funding the Trial

In-Kyu Yoon, acting executive director of vaccine research & development at the Coalition for Epidemic Preparedness Innovations (CEPI), the funders of the trial, highlighted Nipah’s epidemic potential. He emphasized the importance of the trial as a step forward in developing tools to protect against this lethal virus and potentially informing the development of countermeasures for other paramyxoviruses.

Leveraging the ChAdOx1 Platform

The experimental vaccine utilizes the ChAdOx1 platform, the same viral vector vaccine platform that proved successful in the development of the Oxford/AstraZeneca COVID-19 vaccine. This strategic approach leverages previous success to tackle a new and challenging viral threat.

The Road Ahead: 18 Months of Research

The Nipah vaccine project is expected to run over the next 18 months, with researchers anticipating further trials in a Nipah-affected country. The outcome of these trials holds the promise of providing a much-needed defense against Nipah virus, offering hope for communities vulnerable to this deadly pathogen.
