SUMMARY:  

In October 2017, the FDA approved and ACIP recommended a new ‘recombinant herpes zoster’ (RZV) vaccine for adults ≥50 years of age. According to the CDC, this is the “preferred vaccine” to protect against shingles and postherpetic neuralgia when compared to the previously available ‘zoster vaccine live’ (ZVL).  ACIP has released a report that outlines recent recommendations as well as guidance for use of RZV and ZVL in adults.

Note: ZVL will no longer be sold in the United States starting July 1, 2020 | Some pharmacies and clinics may still have ZVL in stock after this date | The CDC states that “This vaccine is safe and may be used until the supply expires (before or by November 18, 2020).“

  • Special Populations

Herpes Zoster and Postherpetic Neuralgia 

  • Herpes zoster is a localized, painful, cutaneous eruption resulting from reactivation of latent varicella zoster virus (VZV) 
  • Approximately one million cases occur each year in the United States  
  • Incidence increases with age 
    • 50–59 years of age: 5 cases per 1,000  
    • ≥80 years: 11 cases per 1,000  
  • Postherpetic Neuralgia is the most common complication  
    • Defined as persistent pain for at least 90 days following the resolution of the herpes zoster rash 
    • Occurs in 10-13% of herpes zoster cases in persons aged >50 years and risk increases with age 

Herpes Zoster Vaccine Recommendations  

RZV is recommended for the prevention of herpes zoster and related complications for immunocompetent adults aged ≥50 years 

  • Two doses of Shingrix provides strong protection against shingles and postherpetic neuralgia (PHN), the most common complication of shingles
    • Shingles Prevention: In adults 50 to 69 years old who got two doses, RZV was 97% effective; among adults 70 years and older, RZV was 91% effective
    • Postherpetic Neuralgia: In adults 50 to 69 years old who got two doses, RZV was 91% effective; among adults 70 years and older, RZV was 89% effective
  • RZV protection remained high (more than 85%) in people 70 years and older throughout the four years following vaccination

RZV is recommended for the prevention of herpes zoster and related complications for immunocompetent adults who previously received ZVL 

  • ZVL effectiveness wanes substantially over time, leaving recipients with reduced protection against herpes zoster 
  • RZV elicited similar safety, reactogenicity, and immunogenicity profiles regardless of prior ZVL receipt 
  • RZV is preferred over ZVL for the prevention of herpes zoster and related complications  
    • In clinical trials, for all age categories, RZV estimates of efficacy were higher than those for ZVL 
    • ZVL efficacy wanes substantially during the 4 years following vaccination

Note: There is no maximum age for RZV 

Clinical Guidance 

  • Administer 2 doses (0.5 mL each) administered intramuscularly 2–6 months apart 
  • RZV may be used in adults aged ≥50 years, irrespective of prior receipt of varicella vaccine or ZVL  
  • Screening for a history of chickenpox (varicella) not required 
  • While RZV is now the preferred vaccine over ZVL, however, ZVL may still be used  in healthy adults ≥60 years in some situations such as an individual who
    • Is allergic to RZV
    • Prefers ZVL
    • Requests immediate vaccination and RZV is unavailable
  • Care should be taken not to confuse ZVL with RZV 
    • ZVL is stored in the freezer and administered subcutaneously 
    • RZV is stored in the refrigerator and administered intramuscularly 
  • Based on expert opinion, RZV should not be given <8 weeks after receipt of ZVL 
  • Coadministration with other vaccines 
    • Recombinant and adjuvanted vaccines, such as RZV, can be administered concomitantly, at different anatomic sites, with other adult vaccines 
    • Concomitant administration of RZV with quadrivalent influenza vaccine (QIV)  
      • No evidence for interference in the immune response to either vaccine or safety concerns  
    • Coadministration of RZV with 23-valent pneumococcal polysaccharide vaccine (PPSV23) and Tdap 
      • Studies are ongoing 
    • The safety and efficacy of administration of two adjuvanted vaccines (e.g., RZV and adjuvanted influenza, either concomitantly or at other intervals 
      • Not yet evaluated 
  • RZV is not a treatment for herpes zoster or postherpetic neuralgia  
  • Pregnancy and breastfeeding 
    • There are no available data to establish whether RZV is safe in pregnant or lactating women  
    • Currently, there is no ACIP recommendation in this population  
    • Consider delaying vaccination with RZV in such circumstance 

KEY POINTS:  

Counseling and Adverse Events  

  • Reactions to the first dose of RZV did not strongly predict reactions to the second dose 
  • Vaccine recipients should be encouraged to complete the series even if they experienced a grade 1–3 reaction to the first dose of RZV  
    • In studies, Grade 3 solicited symptoms were defined as “preventing normal everyday activity” (pain, headache, fatigue, gastrointestinal symptoms, myalgia, shivering) | surface diameter >100 mm (redness/swelling) | tympanic/oral/axillary temperature >39.0 °C (fever)  
    • Grade 3 unsolicited adverse events were also defined as “preventing normal, everyday activities 

Adverse Events

  • The impact of prophylactic analgesics in conjunction with RZV has not been studied 
  • Adverse local events are relatively common and include 
    • Pain  
    • Redness  
    • Swelling  
  • General adverse reactions include  
    • Myalgia  
    • Fatigue  
    • Headache  
    • Shivering  
    • Fever  
    • Gastrointestinal symptoms
  • Severe (rare) events include
    •  Difficulty breathing
    • Wheezing
    • Hives
    • Pale skin
    • Fast heartbeat
    • Dizziness 
  • Contraindications 
    • History of severe allergic reaction (e.g., anaphylaxis) to any component of the vaccine OR after previous dose  

Special Populations 

  • Persons with a history of herpes zoster 
    • Adults with a history of herpes zoster should receive RZV as herpes zoster can recur 
  • Persons experiencing an episode of herpes zoster 
    • Delay vaccination until the acute stage is over and symptoms abate 
      • Studies are ongoing 
  • Persons with chronic medical conditions (e.g., chronic renal failure, diabetes mellitus, rheumatoid arthritis, and chronic pulmonary disease) 
    • Should receive RZV 
  • Immunocompromised persons 
    • As with ZVL, RZV can be used in persons taking low-dose immunosuppressive therapy (e.g., <20 mg/day of prednisone or equivalent or using inhaled or topical steroids) and persons anticipating immunosuppression or who have recovered from an immunocompromising illness  
    • RZV is licensed for all persons aged ≥50 years however, immunocompromised persons and those on moderate to high doses of immunosuppressive therapy were excluded from the efficacy studies and therefore ACIP has not made recommendations regarding the use of RZV in these patients while awaiting further data 
  • Persons known to be VZV negative 
    • Screening for a history of varicella (either verbally or via laboratory serology) is not recommended 
    • However, in persons known to be VZV negative via serologic testing, ACIP guidelines for varicella vaccination should be followed 
      • All healthy adults should be assessed for varicella immunity, and those who do not have evidence of immunity should receive 2 doses of single-antigen varicella vaccine 4-8 weeks apart 
      • RZV has not been evaluated in persons who are VZV seronegative and the vaccine is not indicated for the prevention of chickenpox (varicella)
