          解析：
          考查非謂語(yǔ)動(dòng)詞。break out爆發(fā)，不及物，故不用被動(dòng)。根據(jù)語(yǔ)境事情已經(jīng)發(fā)生，故用完成時(shí)，選B。

     Each year a million cows in Africa die from east coast fever.The disease is spread by 
          tick bites.Young cows are most at risk；they can die within days.Farmers and herders 
          can lose up to half or more of their calves to east coast fever.
                The disease is widespread in eleven countries.And experts say it now threatens ten 
          million more animals in new areas including southern Sudan.
                Researchers 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 keeps
          the disease 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 seven years.They used to lose threefourths of their newborn calves 
          each year.Now,most survive.As a result,many people have extra cattle to sell,and use the
          money 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 a
          shortage.The International Livestock Research Institute made one million doses at the request
          of 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 mobile
          phones have helped lower some barriers to distribution.
               HAMEED NURU:"Now,with the advent of cellular technology,most of the people we
          do 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 sell a bull 
          and use the money to vaccinate all their animals.They understand that they are getting value
          for their money:A cow is worth nearly twice as much if it is vaccinated.
                A goal is to have local people develop businesses supplying the vaccine.
                HAMEED NURU:"People are now seeing 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.
