An experimental vaccine to treat Ebola, ZMapp, was grown in specifically modified leaves of tobacco through pharming techniques. The plants are infected with the virus and then after a week the vaccine is ready to harvest from the plant. However, the vaccine can not be used widescale yet as it hasn't gone through the formal drug approval process by the US FDA (Food and Drug Administration). They plan to go through that process in late 2014. The compound was only first formulated in January of 2014. They expect the first human trials of ZMapp to being in 2015.
