Indications
- prevention of shingles in the elderly
- recombinant adjuvanted Herpes zoster vaccine (Shingrix) recommended for all adults >= 50 years[9]*
- FDA-approved for immunodeficient & immunocompromised[2]
- may lower risk of postherpetic neuralgia in elderly
* regardless of previous immunization or prior infection[13]
Contraindications
- pregnancy & breast feeding (relative contraindications)
- not indicated for prevention of primary varicella virus infection (chickenpox)[14]*
- does not reduce risk of dementia
- may lower risk or delay onset of dementia[18]
- 164 additional days at end of life without a diagnosis of dementia
* safe for patients regardless of history of prior vaccination or infection[13]
Benefit/risk
- Shingrix superior to Zostavax
- number needed to treat (NNT) to prevent one episode of shingles
- 11 when vaccinated at age 60 (Shingrix)[6]
- number needed to treat (NNT) to prevent one episode of shingles
Dosage
* Shingrix also recommended (1 dose) after Zostvax[6][9]
- immunogenicity & safety profile of Shingrix similar in those previously vaccinated with Zostavax & vaccine-naive patients[8]
- Shigrex more effective than Zostavax[10]
- Shigrex more cost effective than Zostavax even when only 1 of 2 doses given[11]
- GRS11[14] recommends two doses IM 2-6 months apart regardless of prior immunization with Zostvax, failing to recognize refs[6][9]
Keep frozen (< -15 degrees C), reconstitute & use immediately. 19,400 plaque forming units per dose
Pharmacokinetics
Adverse effects
- local reactions, most mild to moderate (75%)
- mild systemic reactions (fatigue) 50%
- adverse effects with Shingrix not greater than Zostavax
- 3% of adverse effects with Shingrix serious (hospitalization, life-threatening illness)
- rate of 4.0 serious events per 100,000 doses (Shingrix)
- rate of 4.4 serious events per 100,000 doses (Zostavax)
- most commonly reported adverse events with Shingrix were fever (24%), injection site pain, & chills 4]
- risk of Guillain-Barre syndrome is low (10 excess cases per 1 million vaccinations in one analysis)[5]
Mechanism of action
- contains recombinant varicella zoster virus glycoprotein E with a potent adjuvant
Notes
- covered under Medicare part D of[14]
- two-dose, adjuvanted herpes zoster subunit vaccine (Shingrix) is cost effective[3]
