Shingles (herpes zoster) is caused by the reactivation of a latent varicella zoster virus (VZV) infection, generally decades after the primary infection. Primary VZV infection typically occurs during childhood and causes chickenpox (varicella).
Following primary VZV infection, the virus enters the sensory nerves and travels along the nerve to the sensory dorsal root ganglia and establishes a permanent latent infection. Reactivation of the latent virus causes a localised blistering rash which may be associated with local pain. The vesicle fluid is infectious and can cause chickenpox in non-immune individuals.
The acute phase of shingles pain may be followed by a lengthy period of post herpetic neuralgia (PHN), which is also more common in the elderly.
Shingles can occur at any age and can occur more than once. Risk increases with age with a lifetime risk of one in four. Risk is increased in those who are immunosuppressed.
On 1 September 2013 a shingles vaccination programme for people aged 70-79 years was introduced in Wales. The introduction was phased, with those aged 70 and 79 years eligible in the first year.
From 1st April 2019 individuals who reach their 70th birthday and have not had a shingles vaccine before can have a free shingles vaccine. They will remain eligible until their 80th birthday.
There are two vaccines available:
More information about the vaccine can be found in the Green Book Chapter 28a Shingles.
Guidance in the Green Book Chapter 28a Shingles supersedes the SmPC.
The Complete Routine Immunisation Schedule (PDF) includes information about routine and non-routine vaccinations.
