Vietnam can produce swine flu vaccine

Due to the production of H5N1 influenza vaccine, Vietnam has the ability to create a vaccine against H1N1 swine flu, which is difficult to lack of recombinant gene sources.

Professor Nguyen Thu Van, Director of Vaccine and Biology Company No. 1, said: 'The vaccine production process is nearly the same, the study of successful production of influenza A H5N1 vaccine is the basis for conducting production. other flu vaccines'.

Just two months to produce

According to Professor Nguyen Thu Van, since 2007, the project has researched and developed the technological process of producing H5N1 vaccine in Vietnam, which has been carried out by scientists belonging to the Ministry of Health.

After the research process, the first vaccine products were produced in the laboratory and tested on volunteers. Human trials are continuing. This is the basis for the production of other flu vaccines because the vaccine production processes are nearly identical, Professor Van said. She said after the original strain was differentiated from the outbreak site, within one to two months, domestic units could produce flu vaccines.

Success in manufacturing vaccines against influenza A H5N1 is a premise for domestic scientific units to produce other vaccines.


Dr. Truong Nam Hai, Director of the Institute of Biotechnology, said that the Institute's staff had mastered the differentiation of the original virus anthropomorphic technology in chicken embryos (the original virus was sequenced to get the strain. poison). With this technology, scientists can extract the virus to process and create a flu vaccine.

Lack of recombinant gene sources

Although it is confirmed that Vietnam can actively produce flu vaccines (including swine flu), scientists also face difficulties if they want to produce a vaccine. Normally, after isolating, sequencing the original viral gene sequence, Institute of Standardization and Verification of probiotics (WHO) will send genetic samples to countries wishing to produce flu vaccines. Because of dependence on the source of this virus strain, time for vaccine production will be delayed.

Regarding swine flu, Professor Van said, scientists have discovered the mechanism of transmission of H1N1 flu from human to human. And prevention with Tamiflu medicine is only effective with regular flu.

Dr. Nguyen Van Kiem, Department of Animal Husbandry - Veterinary, Hanoi University of Agriculture 1, said the good news is that the H1N1 influenza virus is not spread to anyone, but depending on the location and physical condition of each person . For people with suitable conditions, when entering the body, influenza A virus will be isolated, developing into a series of disease-causing cells. While there is no flu vaccine available, the most effective preventive measure is to isolate the pathogen.
