RAHWAY, N.J., Oct. 25, 2022 – MSD (tradename of Merck & Co., Inc., Rahway, N.J., USA (NYSE: MRK)announced today that in response to the health and humanitarian crisis of the Sudan ebolavirus outbreak in Uganda, the company plans to produce and donate vials of investigational candidate Sudan ebolavirus vaccine to IAVI, a global nonprofit scientific research organization, for further clinical research use. IAVI plans to use these vials for its ongoing Sudan ebolavirus vaccine development program. The vials will be produced from existing investigational bulk drug substance previously manufactured by MSD and are intended to be used as part of the World Health Organization’s (WHO’s) efforts to fight the outbreak in Uganda. MSD and IAVI are working toward a formal agreement and are collaborating now to accelerate this effort.

“We are proud to work together with IAVI in support of the World Health Organization’s response to address the Sudan Ebola outbreak in Uganda,” said Beth-Ann Coller, executive director, Global Clinical Development Vaccines, MSD Research Laboratories. “We are moving with urgency to prepare these vials and donate them to IAVI as quickly as possible to help support the efforts of the WHO and the people of Uganda as they grapple with this outbreak.”

MSD anticipates that it will fill approximately 50,000 doses for IAVI from the existing bulk drug substance by the end of 2022. Further use in the response to the outbreak will be subject to authorization by applicable health authorities.

Dr. Mark Feinberg, president and CEO of IAVI, said, “We are very grateful to MSD for supplying the investigational vaccine for IAVI, which will help accelerate IAVI’s program. IAVI looks forward to working with partners responding to the ongoing Sudan Ebola outbreak to evaluate vaccine effectiveness and safety. We hope that our efforts may contribute to the response in Uganda should the outbreak persist, and also enable the world to be better prepared for future Sudan Ebola outbreaks.”
