New biological agents developed in China can prevent SARS virus and avian influenza

Introduction: SARS virus haunts us, influenza virus threatens us Chinese scientists have recently developed a new preventive biological agent called recombinant human interferon alpha 2b spray, which is expected to be used to prevent SARS coronavirus infection If we spray this drug into the nose, we may build a "protective wall" to prevent virus invasion The State Food and Drug Administration recently issued a notice that the recombinant human interferon alpha 2b sprays developed by Beijing yuan Pharmaceutical Co., Ltd and other units can be used as a technology reserve as one of the SARS control and emergency use drugs, which can be used for emergency prevention in the outbreak of SARS epidemic, and can now be produced and sold to the national disease control agency The recombinant human interferon alpha 2b spray, which prevents SARS coronavirus infection, was approved by the State Food and Drug Administration on April 2003 24, and entered the clinical trial stage by easy access It was also included in the key technology and product development special program for national atypical pneumonia organized by the Ministry of science and technology On September 17, 2003, it was approved to increase its clinical trial of preventing acute respiratory virus infection such as influenza In the past two and a half years, with the support of relevant departments, hundreds of researchers have worked hard to complete laboratory research, monkey body test and large-scale epidemiological research, and obtained a large number of data It is not only proved that recombinant human interferon alpha 2b spray has significant effect in preventing SARS coronavirus infection, but also has some epidemiological effects on some parainfluenza virus and influenza B virus infection At present, the National Institutes of health of the United States has listed SARS coronavirus as the priority virus of biological defense class C, and vigorously carried out the research of prevention and control agents and product reserves Experts pointed out that the success of the development of new biological agents has a certain effect on the prevention of SARS virus, the safety of medical staff in the face of patients with unknown fever, and the prevention and control of sudden acute respiratory virus epidemic Scientists have also successfully proved that interferon can significantly protect the attack of avian influenza in chickens, suggesting that interferon has a certain role in the prevention of avian influenza Chinese scientists have accumulated considerable strength in interferon research In recent years, scientists have found that four kinds of interferon, such as recombinant human interferon α 2B, have obvious inhibitory effect on the reproduction of SARS virus, and have applied for patent at the earliest time in the world.
