Unique drug against influenza was created Novosibirsk scientists. According to experts, for the immune system it is more secure than produced in chicken or quail embryos. In addition, the vaccine is stored much longer than usual, the correspondent of “MIR 24” Olga Zhemchugova.

In the lab mistake: this is a scientific breakthrough. With the help of the new vaccine was able to cope with two influenza viruses under the name “California” and “Aichi”. While the experiments conducted only on mice.

“We have received preliminary results showed that indeed such artificial antigens able to induce both the cellular immune response and humoral immunity against influenza virus”, – said head of the theoretical Department state research center of Virology and biotechnology “Vector” Sergey Bazhan.

The discovery belongs to scientists from Novosibirsk state research center of Virology and biotechnology “Vector”. A new vaccine is alive. It was created based on the culture of attenuated microorganisms – pathogens viruses. Previously, vaccines were produced using chicken and quail embryos. These drugs is contraindicated in those allergic to chicken protein. Another advantage is a long service life. But immunologists warn that while they are talking about the shelf life of the vaccine, not the period.

“There are literature data about the fact that live vaccines prolong longer immunity than inactivated vaccines. But so we can talk about specific data about the duration of the immune response, then these data we still do not have”, – says Deputy General Director for scientific and production work of the scientific center “Vector” Elena Nechaeva.

Now the vaccine is stored in special containers at minus 196 degrees and waiting in the wings. However, prior to registration of the drug should be about two years. Novosibirsk scientists are planning to develop other vaccines against coronaviruses, which cause about 30% of all respiratory infections.
