- Phase 3 trials to assess the safety and efficacy of the experimental Ebola vaccine co-developed by Merck (MRK +0.2%) and NewLink Genetics (NLNK +0.8%) will commence in two days in Guinea according to a statement by the World Health Organization (WHO). The trials will be conducted in the Basse Guinee region which dealt with the most Ebola cases.
- A "ring vaccination" strategy will be employed whereby everyone who has been in contact with a newly diagnosed Ebola patient will be vaccinated, an approach used to eradicate smallpox in the 1970s.
- Trials of two vaccine candidates, Merck/NewLink and GlaxoSmithKline (GSK +0.1%), in Liberia appear to be working. No new cases have been reported for 13 days.
- Trials for Glaxo's offering will begin in Guinea when supplies are available.
