China can provide vaccines against African swine flu

According to Xinhua, Harbin Veterinary Research Institute, under the Chinese Academy of Agricultural Sciences, has achieved initial results in the study of ASF vaccine.

The institute's team on May 27 confirmed that they have achieved 5 steps in finding the way to produce vaccines, not the official vaccines.

Specifically, step one is that scientists have isolated the ASF virus , found the model to reproduce and the mechanism and infectious capacity.

Destroy infected pigs.

The second step is to create experimental vaccines, which have created two strains of vaccine, showing the effectiveness of biosecurity and the ability to create the immune system for pigs.

The third step is that these two strains of vaccine do not affect the external cell organization, nor cause excretion in pigs.

The fourth step is to determine the amount of vaccine needed to create an immune system with ASF.

The final step is that China has had 'preliminary successes' about clinical trials with new vaccines.

The above 5 steps are the processes for developing a new vaccine and this information deserves good news for Chinese and world farmers.

The Chinese Academy of Agricultural Sciences also claimed to have identified all of the basic elements of the ASF virus, finding many mechanisms for natural inhibition with the virus, completing a preliminary study of immunosuppressive mechanisms. of the virus, as well as identify the types of bugs transmitted from infected pigs to healthy pigs.

China insists that it will accelerate the next step to produce large-scale vaccines, but it has not been able to determine a specific time.

Finding new vaccines against African swine flu is a worldwide effort.

Veterinary staff from 182 countries of the World Organization for Animal Health (OIE) are meeting in Paris this week to focus on developing the most effective vaccine.

The cholera pig in Africa is devastating the swine industry in China, the country with the largest swine herd in the world. The Rabobank Bank of the Netherlands estimates that the size of pigs in China could be reduced by one-third in 2019, or 200 million, according to CNN.

This is almost equal to the total size of pigs in the US and Africa combined.

The virus has spread to all 31 provinces of China and is currently circulating or incubating in pig populations in Tibet and Xinjiang.

African cholera virus is harmless to humans but extremely dangerous to pigs, and so far there is no vaccine or treatment. Originating in Africa, the disease was recorded in Eastern Europe and Russia before it first appeared in China in August 2018.

The epidemic then spread to several other Asian countries, including Vietnam and Cambodia, Thailand and may even spread to Australia.

Veterinary director of the Australian Ministry of Agriculture and also the President of OIE, Mark Schipp said, Spanish veterinary scientists recently claimed to have identified a vaccine for the wild boar in Europe. Europe, but vaccines for domestic pigs have not yet been developed.
