Understanding the Increased Risk in Seniors
The varicella-zoster virus (VZV), which causes chickenpox, remains dormant in the body after recovery. As we age, our immunity to VZV weakens, which can lead to the virus reactivating and causing shingles. This age-related decline in immunity is the primary reason the chances of getting shingles after 70 are considerably higher.
While anyone who has had chickenpox can develop shingles, the risk is strongly linked to age. Around 50% of shingles cases occur in adults aged 60 and above, with the risk increasing with each decade. By age 70, the risk is notably greater, along with a higher chance of complications.
Symptoms of Shingles in Older Adults
Identifying shingles symptoms early is important for prompt treatment. In seniors, symptoms can be more intense and last longer. Key symptoms include:
- Pain, itching, or tingling where the rash will appear.
- A red rash, typically on one side of the body or face.
- Blisters that fill with fluid, then open and crust over.
- Fever, headache, chills, and stomach issues.
- Flu-like feelings before the rash appears.
The Threat of Complications, Especially Postherpetic Neuralgia
Older adults face a higher risk of not only getting shingles but also experiencing serious, long-term complications. Postherpetic neuralgia (PHN) is the most concerning, involving severe, lingering pain in the rash area after it heals, which can be disabling and persist for months or years. Other potential complications include bacterial skin infections, vision problems if the rash affects the eye, and neurological issues like facial paralysis or hearing loss.
Reducing the Chances of Getting Shingles After 70
The most effective method to lower the risk of shingles and its complications is vaccination. The CDC recommends two doses of the Shingrix vaccine for healthy adults aged 50 and older.
The Importance of Vaccination
The Shingrix vaccine is highly effective in preventing shingles. Studies have shown over 90% effectiveness in adults aged 50 and above, and it is also highly effective against PHN. This offers significant protection for older adults against a painful illness. Even if you've previously had shingles, vaccination is recommended to help prevent future episodes.
Comparison of Risk Factors for Shingles
| Factor | Impact on Shingles Risk | Why it Matters for Seniors |
|---|---|---|
| Age | Significantly increases risk with every decade over 50. | Cellular immunity naturally declines, allowing VZV to reactivate. |
| Weakened Immune System | Greatly increases the likelihood of reactivation. | Caused by conditions like cancer, HIV, or immunosuppressive medications. |
| Immunosuppressive Medications | Increases risk due to suppressed immune response. | Commonly used for conditions such as organ transplantation or autoimmune diseases. |
| Psychological Stress | Can trigger a reactivation of the dormant virus. | Seniors may face increased stress from life events or health concerns. |
| Gender | Women are slightly more at risk than men. | The exact reason is unclear, but statistics show a higher incidence in women. |
Strategies for Bolstering Overall Immune Health
Beyond vaccination, maintaining a robust immune system is vital for healthy aging and reducing shingles risk. Key strategies include:
- Maintain a Nutritious Diet: Consume a balanced diet rich in vitamins and minerals from fruits, vegetables, and lean proteins to support immune function.
- Get Regular Exercise: Moderate physical activity improves circulation and immune health. Discuss a suitable plan with your doctor.
- Manage Stress: Stress negatively impacts the immune system. Practice relaxation techniques like meditation or engaging in enjoyable hobbies.
- Prioritize Sleep: Aim for 7-9 hours of quality sleep per night, essential for bodily repair and immune health.
- Stay Hydrated: Adequate water intake supports overall bodily function, including immune responses.
Consulting a Healthcare Provider
If you are over 70 and concerned about shingles risk or suspect an infection, consult a healthcare professional. They can offer personalized advice, discuss vaccination, and provide appropriate antiviral treatment if needed. Early treatment can lessen the severity and duration of shingles and reduce PHN risk.

Conclusion
For individuals over 70, the risk of shingles is considerably higher due to age-related changes in immunity. However, effective preventative measures, particularly the Shingrix vaccine, are available. By staying informed, getting vaccinated, and maintaining overall health, older adults can significantly decrease their risk of shingles and its complications, contributing to a healthier life.
