Scientists have published a scientific article that reveals the causes of the absence of a universal influenza vaccine in the field of medicine.
Experts point out that the constant mutation of the virus, which causes changes in its structure and behavior in the human body, complicates the task of creating a universal drug. Despite the fact that the vaccination is improved every year, the development of universal drugs remains a big challenge.
Scientists emphasize that sometimes due to mutations, the virus can bypass antibodies that act as protection against infections, having a vaccine with the effect of antibody production ineffective.
Currently, the most common influenza subtype is H3N2, which has been most prone to mutations, which easily avoids antibodies, represented by an absolute majority of influenza strains. Dr. Jan Wilson emphasizes that before you start developing the vaccine, it is necessary to understand how to effectively slow or eliminate genome mutations. This will make the infection less resistant to vaccinations and medicines and, in the end, will help to develop a universal drug.
