Cholera vaccine faces major test in Yemen
On 15 June, a group managing the modest global reserve of cholera vaccine decided to dispatch 1 million doses to war-torn Yemen, which is suffering from a massive cholera outbreak. Cases began rising sharply in April and have already reached an estimated 200,000, causing 1300 deaths, most of them in the west of the country. There are now 5000 new cases every day, on both sides of the front lines. The vaccination campaign will be one of the biggest tests yet for the vaccine; the global stockpile was created only 4 years ago and has been used mostly for smaller campaigns. But where to deploy it within Yemen is still under debate.
