Side effects halt Ebola 
vaccine tests

Have your say

Swiss researchers have suspended testing of one of the leading Ebola vaccine candidates after some volunteers reported unexpected side effects.

The Hopitaux Universitaires de Geneve said the trial had been suspended “as a precautionary measure”.

The study involving 59 people began in November.

Researchers reported four 
cases of mild joint pain in the hands and feet of people who 
had the injection 10 to 15 days earlier.

Officials will stop giving the vaccine next week to get more data and liaise with others who are testing it in the US, Canada, Germany and Gabon.

The vaccine was developed by the Canadian government and is licensed to two US companies, NewLink and Merck

The trial of the vaccine is scheduled to resume in January in Geneva.
