because flu viruses change frequently, people often need to get different flu vaccines every year. A new study that could allow human immune cells to identify the same parts of various influenza viruses could be used to develop a broad-spectrum vaccine that does not need to be injected annually.
at the University of Melbourne in Australia and international peers reported the results in a new issue of the British journal Nature Immunology. They found the same parts of influenza A, B and C viruses, confirming that an immune cell called "CD8
T cells" could attack all of them.
researchers developed an experimental vaccine that was injected into laboratory mice, and the results showed that the cells in the mice's immune system were activated to significantly kill various influenza viruses.
, lead author of the study and a professor at the University of Melbourne, said that because influenza viruses have been changing, it has been difficult to predict the types of influenza viruses that will be prevalent in the past and to develop vaccines accordingly. Since such immune cells also exist in the human body, it is expected that a broad-spectrum vaccine will be developed on this basis that is effective against all influenza viruses.
