Study announces a durable vaccine for Ebola

A new study shows the durability of a novel 'disseminating' cytomegalovirus (CMV)-based Ebola virus (Zaire ebolavirus; EBOV) vaccine strategy that may eventually have the potential to reduce ebolavirus infection in wild African ape species.

A cytomegalovirus (CMV)-based vaccine provides long-lasting protective immunity against Ebola virus, and has potential for development as a disseminating vaccine strategy to prevent ebolavirus infection of wild African ape populations.

The multi-institutional study is led by Dr Michael Jarvis at Plymouth University, and is published today, 25th March 2015, in Vaccine.

African apes serve as a main source of ebolavirus transmission into the human population. As a consequence, the prevention of ebolavirus infection in African apes could reduce the incidence of future human ebolavirus outbreaks. Ebola virus is also highly lethal to African apes, and is regarded as a major threat to the survival of these populations in the wild. Such a 'disseminating' vaccine offers hope for both stabilizing these endangered ape populations and protecting humans against the devastating effects of Ebola.
