Shingles can occur at any age, including in children, but the risk rises sharply after 50 and keeps climbing with each decade. About 1 in 3 people in the United States will develop shingles at some point, and the vast majority of cases occur in adults over 50. That said, younger adults and even children can get it under certain circumstances.
How Age Affects Your Risk
Anyone who has had chickenpox (or the chickenpox vaccine) carries the dormant virus that causes shingles. The virus sits quietly in nerve tissue and can reactivate years or decades later. What keeps it in check is your immune system, and as your immune function naturally declines with age, the virus finds more opportunity to resurface.
Data on lifetime prevalence shows the steady climb. Among adults 54 to 59, about 9.7% have had shingles. That rises to 10.7% for those 60 to 64, 14.9% for those 70 to 74, and 22.9% for those 85 to 89. By age 90 and older, more than 1 in 4 people have experienced at least one episode. The risk doesn’t just increase a little each decade; it roughly doubles between your late 50s and late 80s.
Shingles in Children
Children can develop shingles, though it’s uncommon. A large study tracking over 6.3 million children from 2003 to 2014 found an overall rate of 74 cases per 100,000 children per year. The rate was significantly lower in children who received the chickenpox vaccine: 38 per 100,000, compared with 170 per 100,000 among unvaccinated children. That’s a 78% lower rate in vaccinated kids.
Children whose mothers had chickenpox very late in pregnancy face a higher risk, since the virus can pass to the baby before birth. Kids with weakened immune systems from illness or medication are also more vulnerable. Overall, though, pediatric shingles cases dropped 72% between 2003 and 2014 as childhood chickenpox vaccination became widespread.
Why Younger Adults Are Getting Shingles
While shingles is primarily associated with older adults, people in their 30s and 40s are not immune. Research has found that adults as young as 30 with certain chronic conditions develop shingles at rates higher than healthy adults in their 50s. Specifically, adults aged 30 to 39 with conditions like depression, chronic lung disease, diabetes, or high psychological stress had an 18% to 31% higher risk of shingles than immunocompetent adults aged 50 to 59. Adults in their 40s with chronic kidney disease had roughly the same shingles risk as otherwise healthy people a full decade older.
Several factors can lower the age at which shingles strikes:
- Immune-suppressing conditions. HIV, cancer, and organ transplantation all weaken the body’s ability to keep the virus dormant.
- Immune-suppressing medications. Drugs used for autoimmune diseases, chemotherapy, and post-transplant care reduce immune surveillance.
- Chronic diseases. Diabetes, chronic kidney disease, and lung disease are independently linked to higher shingles risk at younger ages.
- Prolonged stress. Periods of intense or sustained stress temporarily weaken immune function and can trigger reactivation.
Why Age Matters for Complications
Shingles at a younger age tends to be milder. The most feared complication is postherpetic neuralgia, a persistent burning or stabbing pain that lingers in the affected area long after the rash heals. No patient younger than 50 reported severe pain at any point during the course of shingles in clinical studies. Among patients older than 60, 6% still had severe pain a month after the rash appeared, and 4% had it at three months. Overall, somewhere between 9% and 14% of all shingles patients experience postherpetic neuralgia at the one-month mark, but the burden falls overwhelmingly on older adults.
This is the core reason age matters so much with shingles. It’s not just that older people are more likely to get it; they’re also more likely to suffer lasting pain from it.
When Vaccination Is Recommended
The CDC recommends the shingles vaccine (Shingrix) for all adults 50 and older, given as two doses separated by two to six months. That age threshold reflects the point where risk and complication severity both begin to climb meaningfully.
There is an important exception for younger adults. Anyone 19 or older with a weakened immune system, whether from a medical condition or medication, is also recommended to get vaccinated. For this group, the second dose can be given as early as one to two months after the first if needed. If you’re under 50, healthy, and have a functioning immune system, vaccination is not currently recommended, largely because your risk of both shingles and its serious complications remains low.
