Merck Supports Jenner Institute to Reach First Milestone in Covid-19 Vaccine Manufacturing

- Recently developed manufacturing platform allows large-scale manufacturing

- Joint team reduced process development time to two months from a year – a critical step to manufacturing Covid-19 vaccine at scale

- "We have brought the future of vaccine manufacturing to the present," says Udit Batra,member of the Merck Executive Board and CEO,Life Science

DARMSTADT,Germany,April 14,2020 -- Merck,a leading science and technology company,and The Jenner Institutetoday announced that the Jenner Institute has laid the foundation for large-scale production of its Covid-19 vaccine candidate,ChAdOx1 nCoV-19.

Merck is partnering with The Jenner Institute in the institute's efforts to develop a safe and effective vaccine for Covid-19

With patients enrolled for clinical trials for this vaccine,rapid development of the large-scale manufacturing process is a critical step in quickly and safely delivering it from the lab to patients.

"We have brought the future of vaccine manufacturing to the present," said Udit Batra,Life Science. "This is an important step in treating Covid-19 and other diseases that impact global public health. This work marks a milestone in the vaccine manufacturing development journey,as clinical testing continues to advance."

Tapping into Merck's previous work provided a solid head start for plans to scale-up the manufacture of Jenner's Covid-19 vaccine candidate. Developing the manufacturing process itself would normally take at least six months to a year,but in just two months' time,Merck supported the Jenner team and their collaborators to evaluate the existing manufacturing platform for use with the new vaccine candidate,and improved critical process steps.

Over the last two years,Merck's collaboration with The Jenner Institute has led to the development of a rapid,scalable platform following good manufacturing practices and using disposable technologies for the Institute's adenovirus platform. While the initial work was developed with a rabies vaccine candidate,the platform was then validated with different adenovirus constructs aiming at accelerating future vaccine development and manufacturing. Speed is a major challenge when facing a new outbreak such as this unprecedented Covid-19 pandemic. The organizations first announced their partnership to develop more robust and scalable vaccine manufacturing processes in April 2018.

"In an unprecedented time period,The Jenner Institute's team was able to develop the 10-liter manufacturing scale process based on the previously generated platform with Merck,preparing us for the next round of scale-up efforts," said Dr. Sandy Douglas,vaccine manufacturing scale-up project lead at The Jenner Institute. "Industry collaborations,such as ours with Merck,showcase the value that these efforts have in accelerating our response to outbreaks and pandemics and quickly delivering lifesaving vaccines to benefit the global population."

About the Jenner Institute

TheJenner Institute was founded in November 2005 to develop innovative vaccines against major global diseases. Uniquely it focuses both on diseases of humans and livestock and tests new vaccine approaches in parallel in different species. A major theme is translational research involving the rapid early-stage development and assessment of new vaccines in clinical trials.

The Institute comprises the research activities of more than30 Jenner Investigatorswho head leading research groups spanning human and veterinary vaccine research and development. Together the Institute Investigators comprise one of the largest non-profit sector research and development activities in vaccinology.

Jenner Institute Investigators,through the support of many funders,are developing new vaccine candidates against major global infectious diseases. New vaccines against malaria,tuberculosis and HIV are currently in field trials in the developing world. Research is also underway on livestock vaccines against foot and mouth disease,avian influenza,bovine tuberculosis and other major causes of economic loss.

The Institute is a partnership between the University of Oxfordand The Pirbright Instituteand is the successor to the former Edward Jenner Institute for Vaccine Research. The Institute is supported by the Jenner Vaccine Foundation,a UK registered charity and advised by the Jenner Institute Scientific Advisory Board.
