A varicella vaccine was first developed by Michiaki Takahashi in 1974 derived from the Oka strain. It has been available in the U.S. since 1995 to inoculate against the disease. Some countries require the varicella vaccination or an exemption before entering elementary school. Protection is not lifelong and further vaccination is necessary five years after the initial immunization.
Varicella zoster virus (VZV) is one of eight herpes viruses known to infect humans Anybody who has not had chickenpox is at risk after exposure to an infected person. Although most people recover from chickenpox uneventfully or with a few minor scars, a small percentage suffer more serious complications. Each year in the United States, 4,000 to 9,000 persons are hospitalized with chickenpox, and up to 100 people die each year. Older children who have not had chickenpox should receive the vaccine before their 13th birthday. It takes from 10 to 21 days after contact with an infected person for someone to develop chickenpox. You will have a body temperature of 38 °C (100 °F) but may be as high as 42 °C (108 °F) in rare cases Historically, varicella has been a disease predominantly affecting preschool and school-aged children.
