Swiss researchers have suspended the
testing of one of the leading Ebola vaccine after some volunteers reported
unexpected side effects.
In a statement issued today, the Hopitaux
Universitaires de Geneve said the trial had been suspended "as a
precautionary measure."
The study which involved 59 people began
in November.
Researchers reported four cases of mild
joint pain in the hands and feet in people who got the shot 10 to 15 days
earlier. Officials will stop giving the vaccine next week to get more data and
liaise with others who are testing the vaccine in the U.S., Canada, Germany and
Gabon.
The vaccine was developed by the Canadian
government and is licensed to two U.S. companies, NewLink and Merck. The trial
is scheduled to resume in January in Geneva.
This is just one of several experimental vaccines currently being tested worldwide
to combat the deadly Ebola outbreak.
The U.S. National Institutes of Health
reported last month that a vaccine being tested in Bethesda, Maryland, appeared safe in an early study and elicited a promising
immune system response.
Since the outbreak began earlier this
year, Ebola has infected more than 17,800 people and killed more than 6,300,
mostly in Liberia, Guinea and Sierra Leone.
