Herpes zoster (HZ), also known as "shingles", is caused by reactivation and multiplication of the ubiquitous varicella zoster virus (VZV) that remains latent in everyone's sensory neurons following varicella, or "chickenpox". Among individuals who live to age 85, the lifetime risk for HZ is 50%, and more than one in five individuals affected by zoster develop post-herpetic neuralgia, resulting in chronic pain. Other serious complications include encephalitis, permanent vision loss, or more rarely, dissemination and death. Fortunately, a live attenuated vaccine is available and can reduce HZ risk by up to 70%. For patients with rheumatoid arthritis (RA), this vaccine has great potential to provide improved quality of life by reducing the incidence and complications associated with zoster. Due to the underlying disease and/or treatments (e.g. steroids) for rheumatoid arthritis (RA), the risk of herpes zoster in RA patients is approximately double in the general population. This increased risk should make prevention of zoster and vaccination exceedingly important for RA patients. In fact, because of a higher overall absolute risk for zoster in RA, the vaccine yields a comparable or even greater absolute risk reduction to reduce the risk of shingles and post-herpetic neuralgia in an RA population as it does in the general population. However, the use of the zoster vaccine in RA patients is very low (< 5%), and less frequently used than for the general population.
National guidelines from the Centers for Disease Control's (CDC) Advisory Committee on Immunization Practices (ACIP) recommend a single dose of the zoster vaccine for all individuals age 60 or older, with the vaccine more recently gaining FDA-approval for administration to persons age 50 and older. While a large number of RA patients would otherwise be recommended to receive this vaccine on the basis of age, theoretical safety concerns related to vaccination likely explain the very low vaccination rates observed. Currently, the Federal Drug Administration (FDA), the ACIP, and the American College of Rheumatology (ACR) consider the live zoster vaccine contraindicated in patients receiving immunosuppressive medications, such as biologic therapies. Such contraindication stems from the theoretical safety concern that these individuals could develop a varicella-like infection from the vaccine virus strain. However, investigators hypothesize that this vaccine can safely be given in this setting, as no published data is available to suggest that these safety concerns are warranted. A growing body of observational data suggests that vaccinating RA patients receiving biologic therapies with this vaccine may in fact be safe. Moreover, and similarly with little or no evidence, the ACIP considers the vaccine safe and acceptable for patients using methotrexate at doses commonly used to treat RA (e.g. <= 25mg/week) and for patients using glucocorticoids at prednisone-equivalent doses of ≤ 20 mg/day.
In light of 1) a substantial elevated HZ risk among RA patients; 2) national data showing most RA patients are not vaccinated for HZ; and 3) the high effectiveness of this vaccine in the general population, the investigators propose to conduct the Varicella zostER VaccinE (VERVE) trial, a randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, and long-term effectiveness of the live herpes zoster vaccine. This study will recruit 1,000 individuals age 50 years or older currently receiving anti-TNF therapy for RA or other diseases. Within a relevant 6-week safety window, the investigators will collect serious adverse events (satisfying a regulatory definition of a SAE) including non-serious events of vaccine-strain varicella-like infection or herpes zoster. Beyond the key public health importance of the clinical question addressed, clinical trial methodological innovations anticipated for this unique large pragmatic trial. Additionally, the investigators will study vaccine tolerability and long-term effectiveness through a linkage to health plan data to allow for cost-effective follow-up while minimizing participant and study-site burden. Results from this study will facilitate the parent trial and change RA management by demonstrating the clinical safety and immunogenicity of the live zoster vaccine among current anti-TNF users. Rheumatologists and other providers will be able to improve the care, outcomes, and quality of life for patients using anti-TNF therapy, substantially decreasing the morbidity of herpes zoster and its complications over a lifetime.

Active Comparator: Zoster Vaccine Live (Zostavax)
Zostavax (zoster vaccine live) is used to prevent herpes zoster virus (shingles) in people age 50 and older. Patients randomized to this arm will receive active Herpes Zoster Vaccine. It is administered as a single 0.65 mL dose subcutaneously in the deltoid region of the upper arm.
Biological: Herpes Zoster Vaccine
Other Name: Zostavax
Placebo Comparator: Placebo Normal Saline
Saline injection: patients randomized to this arm will receive a single 0.65 mL dose subcutaneously in the deltoid region of the upper arm.
Other Name: Normal Saline
- Immunogenicity measured at 6 weeks. [ Time Frame: 6 weeks post vaccination ]The primary outcome will be a two-group t-test between the active and placebo group, comparing the difference in the frequency of VZV-specific T cell response using the Enzyme-Linked ImmunoSpot (ELISPOT) assay from baseline to week 6.
- The clinical effectiveness of the HZ vaccine in reducing longer-term HZ risk [ Time Frame: 2 years post vaccination ]Incident HZ cases occurring up to 2 years following vaccination and beyond will be ascertained among enrollees in Medicare and/or a large commercial health plan using a novel linkage to administrative health plan data. The investigators will examine longer-term reduction in risk for herpes zoster and the potential for decreased vaccine effectiveness over time to prevent HZ, which might suggest waning immunity and the need for re-vaccination. This outcome will be ascertained using administrative claims data among the majority of VERVE participants who are linkable to the health plan data sources available to the trial.
- Estimate vaccine safety [ Time Frame: 42 days post vaccination ]
Evaluate all serious adverse events (SAEs) AND non-serious vaccine-strain VZV events within 42 days of vaccination. Serious adverse events of interest will include all serious adverse events that satisfy the FDA-accepted definition of SAEs (results in death, life threatening, results in or prolongs hospitalization, and any Herpes Zoster event).
Adverse events (non-serious) will include rashes, blisters, fever of greater than 101, sickness/illness. Also, any redness, swelling, tenderness of the injection site or any other body part.
- Vaccine tolerability [ Time Frame: 42 days post vaccination ]Vaccine tolerability will be measured by injection site reactions and RA flares within 42 days following vaccination.
- Evaluate RA disease activity [ Time Frame: 42 days post vaccination ]RA Disease activity will be measured using the clinical disease activity index (CDAI) and the Rapid Assessment of Patient Data (RAPID3).
