The Basics
What Causes Shingles?
Shingles is caused by the Varicella-Soster Virus (VSV)—the same virus that causes chickenpox. After you recover from chickenpox, the virus stays dormant (inactive) in your nerve tissues. Years or even decades later, the virus can “reactivate” as Shingles. It is characterised by a painful, blistering rash that usually appears on one side of the face or body. You cannot “catch” Shingles from someone else, but you can catch chickenpox from someone with Shingles if you haven’t been vaccinated or previously infected.

| Feature | Details |
| Name of Vaccine | Shingrix (non-live, recombinant vaccine). |
| Number of Doses | A two-dose series. |

| Efficacy | Provides over 90% protection against shingles and post-herpetic neuralgia. |
| How it is given | Administered as an intramuscular injection into the upper arm. |
| Suitable Age | Typically recommended for adults 50 years of age and older, or adults 18+ with weakened immune systems. |
Safety & Side Effects
What to Expect After Vaccination
Because Shingrix is a very strong vaccine (designed to wake up an older immune system), it is common to have a reaction. These are signs the vaccine is working:
Local Reaction: Significant soreness, redness, or swelling in the arm (most common side effect).
General: Muscle pain, tiredness, headache, and shivering/fever.
Duration: Symptoms usually last 2 to 3 days. It is recommended to plan a “quiet” couple of days following your injection.
Recognising Symptoms
Symptoms of Shingles
Shingles is unique because it follows the path of a nerve, meaning the rash usually stays on one side of the body.
The “Warning” Phase: Tingling, itching, or intense burning pain in a specific area of skin before any rash appears.
The Rash: Clusters of fluid-filled blisters that look like chickenpox but are concentrated in one “stripe” or area.
Intense Pain: Often described as stabbing, burning, or throbbing.
Systemic Signs: Fever, headache, and light sensitivity.
Post-Herpetic Neuralgia (PHN): Long-term nerve pain that lasts for months or years after the rash has healed (the main complication the vaccine prevents).
Additional Precautions
Managing Shingles Safely
Keep it Covered: To prevent spreading the virus to people who haven’t had chickenpox (especially babies or pregnant women), keep the shingles rash covered with loose clothing or a bandage.
Early Antivirals: If you suspect you have shingles, see a doctor within 72 hours. Antiviral medication is most effective when started immediately.
Avoid High-Risk Contact: Stay away from newborns, pregnant women, and the immunocompromised until your blisters have completely scabbed over.
Hand Hygiene: Wash hands frequently to avoid transferring the virus from the blister fluid to other surfaces.

FAQ
I’ve already had Shingles; do I still need the vaccine?
Yes. You can get shingles more than once. The vaccine significantly reduces the risk of a repeat outbreak and the severity of future nerve pain.
Can the Shingrix vaccine give me Shingles?
No. Shingrix is a non-live vaccine. It contains only a small piece of the virus, making it impossible to cause the disease.
