Neglected tropical diseases, such as cysticercosis and echinococcosis (larval tapeworm infections), can be essential veterinary and public health issues. Zoonotic infections, such as human African trypanosomiasis and a form of human schistosomiasis, are major concerns as they have natural reservoirs in animals. For such diseases, it may be more effective to vaccinate the animal population that are natural reservoirs for certain NTDs. These NTDs negatively impact animal populations, such as livestock, producing a commercial market for these vaccines. Expanded usage of NTD vaccines could impede transmission from an infected animal to a human host. There are ag-vet companies that could develop and test these vaccines that would be administered to animal populations.
