Shingles, also known as herpes zoster, is a painful rash that results from the reactivation of the varicella zoster virus (VZV), the same virus responsible for chickenpox. After a person recovers from chickenpox, the virus remains dormant in the body, typically in nerve cells. However, as we age, our immune system weakens, and the virus can reactivate, leading to the painful condition known as shingles.

The shingles vaccine is a highly effective way to reduce the risk of developing shingles and its complications. The vaccine boosts your immune system, helping to prevent the varicella zoster virus from reactivating. The vaccine is recommended for all healthy adults aged 50 and older, even if you've previously had shingles or received the older shingles vaccine (Zostavax).

By receiving the shingles vaccine, you can reduce the likelihood of developing shingles and protect yourself from the debilitating pain and long-term complications like postherpetic neuralgia. The vaccine is administered in two doses, spaced 2 to 6 months apart, and provides strong protection for several years.
