About this trial

This research is designed to determine if the adjuvanted recombinant glycoprotein E (gE) herpes zoster (HZ) vaccine (Shingrix) has acceptable immunogenicity and safety in people who have undergone allogeneic stem cell transplant (allo-SCT). Specifically, it will determine the effect of the interval after transplantation on the immune response and if an additional dose of vaccine is needed to improve the vaccine-induced responses.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Allo-SCT recipients being age 18 - 79 years at time of allo-SCT.

Written informed consent being obtained from the subject

Two doses of RZV, separated by 2 to 6 months, administered at least 1 year after allo-SCT.

Enrollment at >/= 18 months after second dose of Shingrix.

Disqualifiers

Active Graft Versus Host Disease (aGVHD) at the time of enrollment and receipt of the third dose of RZV

Having received ≥20 mg prednisone for more than 2 weeks (or equivalent) in the 8 weeks preceding enrollment.

Receiving any significant immunosuppressive therapy other than for graft maintenance, in the opinion of the investigator.

Having received a live attenuated vaccine within the last 4 weeks, or inactivated vaccine in the last 2 weeks, prior to enrollment.

Trial outcomes

Primary outcomes

1

Compare the immune response via blood draw of Cohort 1 prior to enrollment to ≥1 year post-transplant

To compare gE-specific CMI immune response of Cohort 1 in allo-SCT who received 2 doses of Shingrix ≥1 years post-transplantation and 18-30 months prior to enrollment across 3 groups defined by the time of vaccination after transplantation.

Time frame
1 Year
2

Compare the immune response via blood draw of Cohort 1 prior to enrollment to ≥1 year post-transplant to immune-competent older recipients

To compare gE-specific CMI immune response of Cohort 1 in allo-SCT who received 2 doses of Shingrix ≥1 years post-transplantation and 18-30 months prior to enrollment to immunologic data previously determined in prior studies of immune-competent older recipients of RZV (age ≥50 years).

Time frame
1 Year
