ACIP Recommends Shingrix for Immunocompromised Adults 


At-risk adults aged 19 and older may soon be eligible

The CDC’s Advisory Committee on Immunization Practices (ACIP) has unanimously recommended the use of GlaxoSmithKline’s Shingrix vaccine in adults 19 years and older who are or will be immunodeficient or immunosuppressed due to disease or therapy.1 Currently recommended only for adults 50 and older, Shingrix helps to prevent shingles (herpes zoster) and its complications.

ACIP’s vote follows a decision earlier this year by the FDA that expanded its original approval of the vaccine to include immunocompromised adults 18 and older.2 Shingrix received FDA approval in 2017. 

The FDA and ACIP recommendations open up protection against shingles to millions of at-risk individuals in the United States who do not meet the current age requirement for the vaccine.

"The ACIP’s vote helps to address an existing unmet need as individuals who are immunocompromised are at an increased risk of the disease,” noted Sabine Luik, Chief Medical Officer & SVP Global Medical Regulatory & Quality at GSK, in a press release from the company.1

According to GSK, the ACIP recommendation is based on clinical studies examining the safety and efficacy of Shingrix in adults 18 and older who had undergone an autologous hematopoietic stem cell transplant and those undergoing treatment for hematological malignancies. Additional safety and immunogenicity data were generated in adults who were, or were anticipated to be, immunodeficient or immunosuppressed due to known disease or therapy. This includes patients with HIV, solid tumors, and renal transplants.

Shingrix combines a non-live antigen (to trigger a targeted immune response) with a specifically designed adjuvant system (to generate a varicella zoster virus-specific immune response). 

A primary infection by the varicella zoster virus (VZV) causes chickenpox (varicella). The virus then lies dormant in the nervous system, usually for decades, before reactivating as shingles (herpes zoster). Shingrix is not indicated for the prevention of chickenpox.

More than 99% of Americans over the age of 50 are infected with VZV from previous exposure, and 1 in 3 will develop shingles in their lifetime.3 The rate increases to 1 in 2 for adults 85 years and older. About 1 million Americans develop shingles annually.

In addition to a weakened immune system, other common risk factors for shingles include age, gender, race, and general health. 

In immunocompetent adults, Shingrix is administered in 2 doses delivered 2 to 6 months apart. In adults who are or will be immunodeficient or immunosuppressed and would benefit from a shorter vaccination schedule, the second dose can be administered 1 to 2 months after the first dose.

The ACIP recommendation has been forwarded to the director of the CDC and the U.S. Department of Health and Human Services for review and approval. Once approved, the final recommendations will be published in a future Morbidity and Mortality Weekly Report.
