Shingles Hard to Bear, Vaccine Hard to Get

And while the majority of cases occur in people older than 60, anyone who has had chickenpox is at risk because the triggering virus, "herpes zoster," is the same.

"The chickenpox virus hibernates in the nerve cells of the spinal cord," said Dr. William Schaffner, chairman of preventative medicine at Vanderbilt University Medical Center. "And when it comes out of hibernation, it travels along those nerves to the surface of the body, causing a stripe of blisters that looks like shingles on a roof."

The rash usually forms in a single stripe curling around the left or the right side of the body. But it can occur on the face where, in severe cases, can leave disfiguring scars and even threaten vision.

Underneath the skin, the virus can damage and even destroy the nerve endings, causing postherpetic neuralgia, also known as post-shingles pain.

Even the slightest irritation -- like a breeze through a T-shirt -- can trigger pain so severe that some people with post-shingles pain even consider suicide, Schaffner said.

The Food and Drug Administration approved Zostavax for people older than 60 who've had chickenpox in 2006. The single shot decreases the risk of shingles by 55 percent, according to a Jan. 12 study in the Journal of the American Medical Association.

But only 10 percent of the 52 million people in the United States older than 60 have had the vaccine.

"Many people don't know that there is such a thing as a shingles vaccine and, frankly, not every doctor knows about it yet either," Schaffner said. "And even the doctors that do know about it may not be promoting it because it's very difficult for people on Medicare to get the vaccine."

Medicare covers the shot, which now runs about $160, for those older than 65 under its Plan D. But the reimbursement process is complicated. Unlike the flu shot -- which doctors can stock, administer and charge for -- doctors have to prescribe Zostavax and send patients to the pharmacy to get it.

Some pharmacies administer the shot. But ones that don't can leave patients "brown bagging" the temperature-sensitive vaccine back to the doctor's office.

There's also a problem on the manufacturing end. Merck -- the maker of Zostavax -- has reported a shortage of the essential ingredient: live but weakened chickenpox virus. But Merck has asked the FDA to broaden the recommendations to include people aged 50 to 59.

Shingles is rare in people under 50, but not unheard of. It tends to only affect younger people with weakened immune system, for whom live vaccines aren't recommended because of the potential to wake the dormant virus, according to the FDA.
