Progress in DNA Vaccine of Porcine Reproductive and Respiratory Syndrome
Progress in DNA Vaccine of Porcine Reproductive and Respiratory Syndrome
Porcine reproductive and respiratory syndrome is one of the most threatening important diseases, which causes serious economic loss of swine industry every year. There is not an effective measure to prevent PRRS today. Vaccine inoculation is the main method to prevent and control the disease. The focus of the vaccine research is genetic engineering vaccine. Especially, the DNA vaccine not only induces humoral immunity, but also stimulates high level of cellular immunity response. It is easy to manufacture and store up. Currently, preliminary results have been achieved in the research of DNA vaccine for PRRS. The progress in DNA vaccine of PRRS is summarized below.
