When did the Marburg virus start?

Marburg virus was first recognized in 1967, when outbreaks of hemorrhagic fever occurred simultaneously in laboratories in Marburg and Frankfurt, Germany and in Belgrade, Yugoslavia (now Serbia).

Is there a vaccine against Ebola?

Recent research advances have produced some effective tools against EVD. These include two vaccines against Ebola virus that have recently received regulatory approval: rVSV-ZEBOV, a single-dose vaccine, made by Merck; and the two-dose Ad26. ZEBOV/MVA-BN-Filo, made by Janssen Vaccines and Prevention5.
