Recently, chicken pox problems are more common in farms around the world. Many farmers have expressed that their chickens have been immunized with chicken pox vaccine, why are they still infected with chicken pox?
1.Only a single immunization
Some farmers think that the incidence of chicken pox is not high and it is easy to treat, so they relax their epidemic prevention. Generally, they are only vaccinated once in the breeding stage of chickens at the age of 40 to 60 days; and if the chickens are in a relatively harsh environment, such as Overcrowding, humidity, poor ventilation, poor sanitation, vitamin deficiency, and more pests and diseases such as mosquitoes and flies in the environment will significantly increase the incidence of chickenpox. Efficient protection.

2.The immune effect was not checked
Some farmers only pay attention to immunization, but do not pay attention to checking the effect of immunity. They think that as long as they are immunized with the vaccine, targeted protection can be produced, but they are unaware of the actual effect of immunity.
After 3 to 4 days after the chicken prickly pox, it can be seen that the chicken thorn is slightly red and swollen, and blisters and papules appear, indicating that the inoculation is successful, and then a scab is formed, which can fall off after 2 to 3 weeks. If the immune response rate is low, it needs to be replanted in time, otherwise it is easy to cause a decrease in the immune protection effect or immune failure.

3.Believing that vaccines are omnipotent
Some farmers think that the chickens will not get sick if they are vaccinated, but ignore the impact of environmental factors on chickenpox. A good environment can effectively reduce the spread and infection of fowlpox virus by blood-sucking insects in the environment, thereby effectively controlling the incidence of fowlpox. When there are more mosquitoes, the protection rate of the vaccine will decrease; therefore, effective control of mosquitoes and good biosecurity status is one of the important measures to reduce the incidence of chickenpox.
