It is also possible to get chickenpox after receiving the chickenpox vaccine. After vaccination, the body will produce antibodies accordingly, but it is not 100% effective, and there are a small number of people who do not produce antibodies. If this group of people are exposed to chickenpox patients and at the same time the patients’ resistance is poor, they may get chickenpox. So, whether or not you get the chickenpox vaccine, whether or not you produce antibodies, you should usually stay away from people with chickenpox. This is because chicken pox is extremely contagious, not only contact with the patient’s herpes fluid will be contagious, but also through the air droplet transmission, must be well protected. The best way to protect yourself is to get the chickenpox vaccine, which is generally recommended for children over the age of one.
