Is There a Vaccine for Bird Flu?
Human avian influenza virus may be a genetic recombination produced by human and avian influenza viruses. Preventing influenza can reduce the occurrence of human avian influenza to a certain extent. Influenza vaccination can greatly reduce the probability of this genetic recombination. Avian influenza is a type A influenza virus that is polymorphic, with a spherical diameter of 80 to 120 nm and a capsule. According to the antigenicity of the outer membrane hemagglutinin (H) and neuraminidase (N) proteins, it can be divided into 15 H subtypes (H1 to H15) and 9 N subtypes (N1 to N9). In addition to infecting humans, influenza A virus can also infect pigs, horses, marine mammals, and poultry. The main subtypes of avian influenza virus that infect humans are H5N1, H9N2, and H7N7. Among them, patients infected with H5N1 are seriously ill and have a high mortality rate.

- The first is to exercise, improve physical fitness and immunity; the second is not to promote illness and persist in work.
- Main experience
- Genetically engineered vaccines are the development direction of human avian influenza vaccines, but there are still some problems in the process of vaccines from laboratory to use. In order to safely, effectively and quickly respond to the next epidemic, the vaccine safety should be comprehensively evaluated and the costs must be correctly faced -Benefit issues, support vaccine research, production from the legal, human, material, financial and technical levels, improve vaccine productivity, and correctly evaluate the vaccine population.
