Shingles (Zoster)

Introduction

Shingles is caused by the reactivation of the latent varicella–zoster virus (VZV) from previous infection with chickenpox and often occurs following waning VZV cellular immunity, which presents as a painful vesicular rash with a dermatomal distribution. Latency also occurs after chickenpox vaccination. Prodromal pain lasts 3–4 days, but it can extend to a week. A maculopapular rash develops into clusters of vesicles. In immunocompromised persons, multidermatomal disease may occur. Postherpetic neuralgia (PHN) is the most common complication of shingles. This pain can be extremely severe and may persist over years. Other complications include ophthalmic involvement, bacterial superinfection, cranial and peripheral nerve palsies, meningoencephalitis, pneumonitis, hepatitis, and acute retinal necrosis. Observational studies in older adults suggest that shingles is associated with increased risk of stroke and myocardial infarction, particularly in the first 6 months post-infection.

For further information on shingles in older adults, please refer to the ‘Malaysian Society of Geriatric Medicine Position Statement for Vaccine Preventable Diseases in Older Adults’ (www.msgm.com.my).

Implications for Healthcare Workers (HCWs)

There are no specific recommendations for RZV for HCWs.

Co-administration

Studies on co-administration of RZV with influenza, PPSV23, PCV13, and Tdap have found no evidence of interference in the immune response and no safety concerns.

Evidence of Safety & Effectiveness

Immunocompetent persons

  • Efficacy of the recombinant zoster vaccine (RZV) for prevention of herpes zoster in 3- year studies, was 97.2% in persons aged >50 years and 89.9% in participants aged >70 years.
  • Efficacy for prevention of postherpetic neuralgia was 91.2% in adults aged >50 years and 88.8% in those aged >70 years.
  • Humoral and cellular immune responses persisted for 10 years in older adults after the initial 2-dose RZV.
  • Humoral immune response to RZV post-2-dose was comparable in adults >65 years who were previously vaccinated with live attenuated zoster vaccine, Zostavax (ZVL), >5 years ago compared to ZVL-naïve adults. RZV was well tolerated in both study groups and no safety concerns were identified up to one month post dose 2.
  • Vaccination with RZV has been linked to a decreased incidence of major adverse cardiovascular events.
  • Recent, highly publicized, evidence confirms previous findings of a protective effect against dementia by demonstrating that RZV reduced the probability of a new dementia diagnosis by approximately one-fifth over a seven-year follow-up period.

Evidence for immunocompromised patients

  • The efficacy of RZV in prevention of shingles in immunocompromised autologous haematopoietic stem cell transplantation (HSCT) recipients was 68.2%.
  • Immunogenicity and safety studies on patients with haematological malignancies showed that humoral and cellular immune responses persisted above the baseline 13 months after vaccination. Post-hoc analysis showed vaccine efficacy of 87.2% against shingles in the population of immunocompromised adults, 18 years and older. The safety profile was acceptable in adults with haematological malignancies.
  • Recombinant zoster vaccines were immunogenic in patients with solid tumours receiving immunosuppressive therapy regimen. Immunogenicity persisted 12 months after vaccination regardless of timing of the first vaccination in relation to the start of chemotherapy.
  • Recombinant zoster vaccine was immunogenic in renal transplant patients > 18 years of age under chronic daily suppression and the immunogenicity persisted through one year after vaccination.
  • The most common solicited adverse reactions (grade1-3) following RZV vaccine were pain (78%), myalgia (45%), and fatigue (45%).
