阅读理解. Each year a million cows in Africa die from east coast fever.The dia is spread by tick bites.Young cows are most at risk；they can die within days.Farmers and herders can lo up to half or more of their calves to east coast fever.  The dia is widespread in eleven countries.And experts say it now threatens ten million more animals in new areas including southern Sudan.  Rearchers first developed an experimental vaccine against east coast fever thirty years ago.The vaccine works by a process called "infection and treatment"．The animals are infected with whole parasites and treated with antibiotics at the same time.This keepsthe dia from developing. Controlling east coast fever has meant a better life in areas that have gotten the vaccine.For example,the vaccine has been available for a group of Maasai herders in northern Tanzania for about ven years.They ud to lo threefourths of their newborn calves each year.Now,most survive.As a result,many people have extra cattle to ll,and u themoney to pay for school for their children. But making the vaccine more widely available-especially in rural areas-has been difficult.Farmers have been using supplies produced in the nineteen nineties.Recently there was ashortage.The International Livestock Rearch Institute made one million dos at the requestof African officials.But that supply is only temporary.Another problem is that the vaccine must be kept extremely cold.  Now,the nonprofit Global Alliance for Livestock Veterinary Medicines is trying to expand production and lower the cost.GALVmed spokesman Hameed Nuru says mobilephones have helped lower some barriers to distribution. HAMEED NURU:"Now,with the advent of cellular technology,most of the people wedo reach,such as the Maasai pastoralists,they all have cell phones.And they now call the delivery agent who can now come and meet them at a particular place and do the vaccination for them."  The vaccine is not cheap.But Hameed Nuru says the herders get together to ll a bull and u the money to vaccinate all their animals.They understand that they are getting valuefor their money:A cow is worth nearly twice as much if it is vaccinated.  A goal is to have local people develop business supplying the vaccine.  HAMEED NURU:"People are now eing that they can actually make a business from supplying this vaccine and getting out to the very rural areas where there is a market for this." The efforts are supported by the Bill and Melinda Gates Foundation and the British government.East Coast Fever Features of eastcoast fever  ◆Spread by tick bites ◆__1__young cows easily in a few days ◆Being a __2__to many animals  The measure to prevent the dia from __3__  Developing a__4__The difficultiesin__5__the vaccine  ◆For a__6__of the vaccine ◆Kept at a very low__7__  The__8__to making the vaccine available ◆Trying to expand production and make the vaccine__9__ ◆__10__the vaccine to farmers with the help of mobile phones 题型：未知难度：其他题型
