LONDON, May 21 (Reuters) - A vaccination campaign aimed at beating an outbreak of Ebola in Congo began on Monday in the port city of Mbandaka, where four cases of the deadly disease have been confirmed.
Use of the VSV-EBOV shot - an experimental vaccine developed by Merck - marks a "paradigm shift" in how to fight Ebola, said the World Health Organization's head of emergency response, and means regions with Ebola outbreaks can in future expect more than just containment of an outbreak with basic public health measures such as isolation and hygiene.
