Shingles Vaccination for Individuals Who Have Never Had Chickenpox
Individuals who have never had chickenpox (varicella) should receive the recombinant zoster vaccine (Shingrix) rather than the live zoster vaccine (Zostavax) if they are eligible for shingles vaccination based on age or risk factors.
Understanding Varicella-Zoster Virus (VZV)
- Varicella-zoster virus causes two distinct clinical manifestations: chickenpox (varicella) as the primary infection and shingles (herpes zoster) as a reactivation of latent virus 1, 2
- After primary infection, VZV remains dormant in the sensory nerve ganglia and can reactivate later in life, causing shingles 1, 3
- Shingles typically affects older adults and immunocompromised individuals 2
Vaccination Options for Shingles Prevention
There are two types of shingles vaccines:
Recombinant Zoster Vaccine (RZV, Shingrix)
Live Zoster Vaccine (ZVL, Zostavax)
Recommendations for Individuals Without Prior Chickenpox
- For individuals with no history of chickenpox, antibody testing can determine VZV immunity status 4
- If seronegative (no VZV antibodies):
Special Considerations
- Immunocompromised patients: Recombinant zoster vaccine (Shingrix) is recommended for immunocompromised patients aged 18 and over, particularly those starting JAK inhibitors 4
- Age considerations: Shingrix is recommended for all adults aged 50 years and over regardless of prior chickenpox history 4, 2
- Safety profile: The recombinant vaccine has demonstrated excellent safety and efficacy 2
Potential Risks of Live Vaccine in VZV-Naïve Individuals
- Individuals who have never had chickenpox are at risk of developing vaccine-strain varicella infection if given the live zoster vaccine 4
- A documented case showed cutaneous vaccine dissemination in a patient lacking primary immunity to varicella who received the live zoster vaccine 4
Conclusion
For individuals who have never had chickenpox but are eligible for shingles vaccination based on age or risk factors, the recombinant zoster vaccine (Shingrix) is the appropriate choice. It provides protection against shingles without the risk of causing primary varicella infection that exists with the live vaccine 4, 2.
