Postherpetic neuralgia (PHN) is neuropathic pain that occurs due to damage to a peripheral nerve caused by the reactivation of the varicella zoster virus (herpes zoster, also known as shingles). PHN is defined as pain in a dermatomal distribution that lasts for at least 90 days after an outbreak of herpes zoster. [ 1 ]
The vaccine requires two doses and is over 90% effective at preventing shingles and postherpetic neuralgia (nerve pain) in adults 50 years and older with healthy immune systems.
While we’re talking vaccines this fall, this is what you should know about getting vaccinated against shingles. At vaccine time, don’t forget about shingles. Here’s who should get shots and ...
The vaccine reduced rates of persistent, severe pain after shingles by 66% in people who contracted shingles despite vaccination. [59] Vaccine efficacy was maintained through four years of follow-up. [59] It has been recommended that people with primary or acquired immunodeficiency should not receive the live vaccine. [59]

A zoster vaccine is a vaccine that reduces the incidence of herpes zoster (shingles), a disease caused by reactivation of the varicella zoster virus, which is also responsible for chickenpox. [8] Shingles provokes a painful rash with blisters, and can be followed by chronic pain ( postherpetic neuralgia ), as well as other complications.
Shingles can lead to serious problems such as deafness, long-lasting pain, and blindness.
Reactivation of the virus cause herpes zoster, commonly known as shingles, is seen in a dermatomal or cranial nerve distribution corresponding to the ganglion in which the latent virus resided. After the herpetic rash resolves, an additional period of postherpetic neuralgia may persist for weeks to months. [15]
