This achievement is the culmination of a year of dedicated research by scientists at Razi's Mashhad branch, using state–of–the–art reverse genetics technology. Influenza, A virus, particularly strain H5, poses a serious threat to poultry and human health. The virus can cause extensive losses in poultry flocks and, in some cases, severe respiratory illness in humans.
Recognizing the urgent need for an effective vaccine, Razi's Mashhad branch embarked on a research project to develop a vaccine against H5 influenza. Razi scientists successfully designed and produced the H5 influenza vaccine seed, leveraging the power of reverse genetics technology. This marks a major milestone in Iran's fight against influenza, placing the country among the few nations with this valuable technology.
 Dr. HamidReza Farzin, the head of Razi Institute Mashhad branch, expressed his pride in the team's accomplishment, stating, "The tireless efforts of our researchers have finally borne fruit. This breakthrough not only safeguards our poultry industry but also strengthens our preparedness against potential influenza outbreaks that could pose a threat to public health." The development of the H5 influenza virus vaccine seed is a testament to Razi's commitment to innovation and its dedication to protecting human and animal health. The Institute is now working to formulate the vaccine and conduct clinical trials to pave the way for its licensure and widespread use.
