A person with shingles can pass the varicella-zoster virus to anyone who isn’t immune to chickenpox. This usually occurs through direct contact with the open sores of the shingles rash. Once infected, the person will develop chickenpox, however, not shingles.
If you’ve had chicken pox or the immunization for chicken pox, you already have varicella zoster in your nervous system. (Even if you’re in the same room with someone with the rash, there’s no risk of further transmission.)

Herpes zoster, commonly known as shingles, is caused by the Varicella-Zoster virus (VZV). Following a primary infection, VZ Venters the body via the respiratory tract, spreads via the blood to the skin, and typically results in chickenpox. This primary infection leads to lifelong immunity that almost always prevents further episodes of chickenpox due to repeat infections.
Do not scratch the skin where the rash is located. This may increase the risk of secondary bacterial infection and scarring. Over-the-counter (OTC) antihistamines (Benadryl) and topical creams (Lidocaine cream) can relieve the itching.
The Immunise Australia program also provides a free ‘catch-up’ vaccination for children between 10 to 13 years old who haven’t yet been vaccinated or had chickenpox. This free vaccination is available from local doctors and immunisation clinics. Talk to your GP for more information.
Avoid being around pregnant women. The herpes-zoster virus can cause serious health risks in both pregnant women and their babies. Risks include pneumonia and birth defects. If you realize that you exposed yourself to a pregnant woman, notify her right away so she can contact her OB/GYN for recommendations. Be especially careful to avoid pregnant women who haven’t had chickenpox or the vaccine for it.
Anyone who has ever had chickenpox can develop shingles. Most adults in the United States had chickenpox when they were children, before the advent of the routine childhood vaccination that now protects against chickenpox.
Shingles: An acute infection caused by the herpes zoster virus, the same virus as causes chickenpox. Shingles is most common after the age of 50 and the risk rises with advancing age. Shingles occurs because of exposure to chickenpox or reactivation of the herpes zoster virus. The virus remains latent (dormant) in nerve roots for many years following chickenpox.
So while the old vaccine will remain on the market, the C.D.C. committee voted to make Shingrix the preferred vaccine and recommended it for all adults over age 50 — a group younger by a decade than those earlier encouraged to get Zostavax.
The family name of all the herpesviridae derives from the Greek word herpein (“to creep”), referring to the latent, recurring infections typical of this group of viruses. Zoster comes from Greek zōstēr, meaning “belt” or “girdle”, after the characteristic belt-like dermatomal rash. The common name for the disease, shingles, derives from the Latin cingulus, a variant of Latin cingulum meaning “girdle”.
The antigen in Shingrix is a surface protein of the varicella zoster virus produced by culturing genetically engineered Chinese hamster ovary cells. Vaccination consists of two doses of vaccine, give at months 0 and 2-6. In some cases, people who want to take the vaccine will need to acquire it from a pharmacy if the healthcare provider does not stock it.
Previous Stanford University research had shown that macrophages — immune cells essential to tackling infections and repairing injured tissue — in patients with coronary artery disease have excessive numbers of molecules involved in the uptake of glucose, forcing accelerated metabolism of the sugar.
The disease results from virus particles in a single sensory ganglion switching from their latent lysogenic cycles to their active lytic cycles. In contrast to the herpes simplex virus, the latency of VZV is poorly understood. The virus has never been successfully recovered from human nerve cells by cell culture. The complete sequence of the viral genome was published in 1986. Virus-specific proteins continue to be made by the infected cells during the latent period, so true latency, as opposed to chronic, low-level, active infection, has not been proven to occur in VZV infections. Although VZV has been detected in autopsies of nervous tissue, there are no methods to find dormant virus in the ganglia of living people.
Reconstitute RZV using only the adjuvant solution provided. After reconstitution, administer RZV immediately by the intramuscular route or store the reconstituted vaccine refrigerated between 2° and 8°C (between 36° and 46°F) and use within 6 hours. Discard reconstituted vaccine if not used within 6 hours or if frozen. If vaccine reconstituted with other than the supplied adjuvant solution is administered it should repeated. The dose can be repeated immediately. There is no interval that must be met between these doses.
It is important to stay in the clinic for 15 minutes after getting any vaccine because there is an extremely rare possibility, less than 1 in a million, of a life-threatening allergic reaction called anaphylaxis. This may include hives, difficulty breathing, or swelling of the throat, tongue or lips. Should this reaction occur, your health care provider is prepared to treat it. Emergency treatment includes administration of epinephrine (adrenaline) and transfer by ambulance to the nearest emergency department. If symptoms develop after you leave the clinic, call 9-1-1 or the local emergency number.
Unfortunately, individuals can get shingles more than once, so recurrence is possible. Although more than two shingles outbreaks in a lifetime is rare, they are significant because they usually occur in people with multiple medical problems or increasingly weakened immune responses. This complication of shingles often indicates that the person has increasing medical problems that need to be diagnosed or aggressively treated (or both).

The U.S. Food and Drug Administration approved a live zoster vaccine, marketed under the name Zostavax, in 2006. A single dose of vaccine is recommended for most people 60 and older, whether or not they have already had shingles. In clinical trials, the vaccine cut the risk of shingles by half. The vaccine was even more effective in reducing the risk of postherpetic pain that lingers after shingles has disappeared.
Individuals should also receive care as soon as possible if they have a medical illness that decreases their ability to fight off infection; these people may be able to avoid complications if treated in the early stage of shingles.
