Core Viewpoint - The company, Reap Bio (300119.SZ), currently does not have a specific vaccine for the H5N5 avian influenza, but its existing H5+H7 vaccine theoretically offers good protection against the prevalent H5N5 strain due to its genetic components [1] Group 1 - The company and the domestic market currently lack a dedicated H5N5 avian influenza vaccine [1] - The H5N5 strain circulating abroad belongs to the clade 2.3.4.4b genetic branch, which is crucial for evaluating vaccine efficacy [1] - The existing H5+H7 vaccine contains components of the clade 2.3.4.4b strain, suggesting it can provide adequate protection [1]
