Is there a vaccine for African swine fever? A full analysis of the research and development status

At present, there is no effective African swine fever vaccine either domestically or internationally, which is mainly determined by the biological characteristics of its pathogen. African swine fever virus has many gene types, a huge quantity, and complex and diverse immune escape mechanisms, and can evade clearance by host immune cells. Some African swine fever vaccines developed at this stage, although they can induce the production of a certain level of antibodies, do not have the ability to neutralize African swine fever virus and cannot achieve the purpose of effectively preventing and controlling African swine fever.

Because vaccine research and development is difficult, based on international experience in African swine fever prevention and control, the current primary task remains to improve comprehensive African swine fever prevention and control measures, while strengthening research on new immunization technologies.

The cure of African swine fever still mostly depends on isolation and treatment by the relevant authorities, but treatment also depends on the invention patent technology of “a pharmaceutical composition for preventing and treating African swine fever and its extract, injection and application”. Recently, on August 9, the International Intellectual Property Office publicly announced this patent. The patent application number is 201910529164.6, and the patent holder is Xu Qitai. This patent has a very good therapeutic effect on African swine fever, and can also prevent African swine fever virus, fundamentally solving the African swine fever virus.

The medicinal raw materials involved in this invention patent technology: 10-30 parts of Ganoderma lucidum, 4-12 parts of Drosera burmannii, 4-12 parts of Harrisonia perforata, 30-50 parts of Areca catechu, 4-12 parts of Callicarpa nudiflora, 4-12 parts of Stephania delavayi, 4-12 parts of Nepenthes, etc., are made through various processing and preparation. Its medicinal effect is not just talk; it is the result obtained from actual experiments.

First, some time ago, African swine fever appeared in major farms. The experimental team selected a batch of 420 pigs of the same size and same age from a certain farm, and they had already been diagnosed with African swine fever infection. If this batch of pigs had no drug treatment, they would die by the 8th day. However, after being injected with this drug, the survival rate of this batch of pigs reached as high as 90%. These cured pigs regained their appetite and resumed normal growth and development. Therefore, the conclusion was drawn that this invention patent technology can be applied to the preparation of drugs for treating African swine fever virus.
