Can Vaccines Really Prevent Shingles?
The Big Picture
Shingles, a painful skin condition caused by the reactivation of a virus, can be prevented with vaccines. This article explores the available vaccines and their effectiveness in stopping shingles before it starts.

Understanding Shingles
Shingles is caused by the varicella-zoster virus, the same virus that causes chickenpox. After someone recovers from chickenpox, the virus can stay dormant in their body and reactivate later as shingles. Shingles are known for causing painful skin rashes and can lead to complications like postherpetic neuralgia, a persistent pain condition.
The Role of Vaccines
Vaccines are a powerful tool in preventing shingles and reducing its severity if it does occur. Two types of vaccines are available: the recombinant zoster vaccine (RZV) and the zoster vaccine live (ZVL). RZV is preferred for most individuals due to its higher efficacy and longer-lasting protection. ZVL, although less effective, is still used in countries where RZV is not available.
Who Should Get Vaccinated?
It's recommended that all adults over the age of 50 receive the shingles vaccine, particularly the RZV. For those who are immunocompromised or have specific health conditions, vaccination is advised even earlier, starting at age 19. This proactive step can significantly decrease the risk of developing shingles and its complications.
FAQs

It reduces the risk of shingles and its complications.
Key Takeaways
Vaccination is a crucial step in preventing shingles, especially in older adults and those with weakened immune systems.
