The development of a universal influenza vaccine with a wide spectrum and duration of action is one of the serious public health problems. This study is dedicated to optimization of an immunogen covering the M2e epitopes of influenza A viruses circulating in the natural reservoir, as well as the creation of a prototype of a universal influenza vaccine with subsequent quantitative and qualitative assessment of the induced anti-M2e responses in ferrets.
