Do recovered pigs from African swine fever have antibodies?

Due to African swine fever, farmers in many areas have become very cautious. Some farmers could not bear the losses and began to move into other industries. So do recovered pigs from African swine fever have antibodies? Let's take a look at this question together!

1. Do recovered pigs from African swine fever have antibodies?

Recovered pigs from African swine fever carry the virus for a long time. Although they have antibodies, the immunity does not last long, so prevention and control work against African swine fever should still be strengthened for recovered pigs.

2. Why is there no vaccine for African swine fever?

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

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