Shingrix, otherwise known as recombinant zoster vaccine (RZV), is an immunization to prevent reactivation of the varicella-zoster virus which causes shingles, as well as its related complications.

What is Shingrix used for?

Shingrix is used for the prevention of the virus which causes shingles, the varicella zoster virus (VZV). VZV is the same virus that causes chickenpox. A person infected with chickenpox continues to carry the virus in their body in a dormant, or inactive, state. The virus can reactivate many years later after a chickenpox infection and cause shingles, which can result in serious complications.

Expert tips for using Shingrix

  • Shingles vaccination with Shingrix is the only way to protect against shingles and postherpetic neuralgia (PHN), a common and serious complication of the herpes zoster virus.

  • Adults aged 50 years or older should receive two doses of Shingrix to prevent shingles and its complications.

  • Adults aged 19 years or older with weakened immune systems should also receive two doses of Shingrix.

  • Even if you had shingles in the past, you should still get Shingrix injections since it can help prevent future recurrences.

  • Shingrix should be administered even to those who do not remember having had chickenpox.
