Do you need chickenpox vaccination for children: detailed information about the vaccine and the opinions of doctors

Chickenpox, or chickenpox – is an acute infectious disease that causes a virus from the herpesvirus family (Latin Herpesviridae) varicella zoster (Varicella Zoster).

In most cases, the course of the disease is benign, but sometimes its development can lead to serious complications – encephalitis (inflammation of the brain), myocarditis (heart damage, which in most cases is also inflammatory), lymphadenitis (inflammation of the lymph nodes), pyoderma (purulent lesions of the skin).

In Japan, a study was conducted, which showed that even 20 years after it, a person is almost 100% resistant to chicken pox.
