Patient Education

Live Shingles (Zoster) Vaccine (ZVL)


Why get vaccinated? Live zoster (shingles) vaccine can prevent shingles. Shingles (also called herpes zoster, or just zoster) is a painful skin rash, usually with blisters. In addition to the rash, shingles can cause fever, headache, chills, or upset stomach. More rarely, shingles can lead to pneumonia, hearing problems, blindness, brain inflammation (encephalitis), or death. The most common complication of shingles is long-term nerve pain called postherpetic neuralgia (PHN). PHN occurs in the areas where the shingles rash was, even after the rash clears up. It can last for months or years after the rash goes away. The pain from PHN can be severe and debilitating. About 10 to 18% of people who get shingles will experience PHN. The risk of PHN increases with age. An older adult with shingles is more likely to develop PHN and have longer lasting and more severe pain than a younger person with shingles. Shingles is caused by the varicella zoster virus, the same virus that causes chickenpox. After you have chickenpox, the virus stays in your body and can cause shingles later in life. Shingles cannot be passed from one person to another, but the virus that causes shingles can spread and cause chickenpox in someone who had never had chickenpox or received chickenpox vaccine.

Varicella (Chickenpox) Vaccine


Why get vaccinated? Varicella (also called chicken pox) is a very contagious viral disease. It is caused by the varicella zoster virus. Chickenpox is usually mild, but it can be serious in infants under 12 months of age, adolescents, adults, pregnant women, and people with weakened immune systems. Chickenpox causes an itchy rash that usually lasts about a week. It can also cause: fever tiredness loss of appetite headache More serious complications can include the following: skin infections infection of the lungs (pneumonia) inflammation of blood vessels swelling of the brain and/or spinal cord coverings (encephalitis or meningitis) blood stream, bone, or joint infections Some people get so sick that they need to be hospitalized. It doesn't happen often, but people can die from chickenpox. Before varicella vaccine, almost everyone in the United States got chickenpox, an average of 4 million people each year. Children who get chickenpox usually miss at least 5 or 6 days of school or childcare. Some people who get chickenpox get a painful rash called shingles (also known as herpes zoster) years later. Chickenpox can spread easily from an infected person to anyone who has not had chickenpox and has not gotten chickenpox vaccine.
