As Ebola outbreak spreads in Congo, concern grows over supplies of experimental vaccine

Should the outbreak spread more widely in cities, the scale of the outbreak could tax the available supplies of an experimental vaccine being used to help contain spread, said Peter Salama, who heads the World Health Organization’s (WHO) emergencies program.

Ebola vaccine technology could speed up development of other vaccines

In addition to an Ebola vaccine, the Coalition for Epidemic Preparedness Innovations is currently funding the development of vaccines for Lassa fever, Middle East respiratory syndrome, Nipah virus, and coronavirus at the Jenner Institute; and by using the same technology as the Ebola vaccine — called viral vectors — researchers can significantly reduce the time it takes to develop vaccines.

Intradermal immunization by Ebola virus GP subunit vaccines using microneedle patches protects mice against lethal EBOV challenge

Researechers compared immune responses induced by Ebola virus glycoprotein subunit vaccines via intradermal immunization with microneedle (MN) patches and the conventional intramuscular injection in mice.

Crucial test of Ebola vaccine raises hopes, doubts in Congo

Even if the vaccine helps, there are serious hurdles. The shots must be transported deep into forests with few paved roads without it spoiling in the heat, and health workers must identify and track down anyone who's had contact with a sick person and persuade them that shots pushed by foreigners could save their lives.
