Prior clinical studies of zoster vaccine enrolled subjects without a history of herpes zoster (HZ), so there are limited data on safety and immunogenicity in vaccinees with a prior history of HZ. This study was conducted to evaluate the safety and immunogenicity of zoster vaccine recipients who had a prior episode of HZ.
A total of 101 subjects > or = 50 years of age with a prior history of HZ were enrolled. They were stratified by number of years since their HZ (5 to 9 years and > or = 10 years, in an approximate 2:1 ratio), and randomized 1:1 to one of two vaccination groups. On day 1, Group I was administered zoster vaccine and Group II received placebo. At week 4, Group I received placebo and Group II received zoster vaccine. Subjects were followed for adverse experiences (AEs), exposure to varicella or HZ, and development of any varicella/varicella-like or HZ/HZ-like rashes, for 28 days after each injection. Blood samples were obtained prior to study injection on day 1 and week 4, and at week 8. Serum was assessed for varicella-zoster virus (VZV) antibody concentration by glycoprotein enzyme-linked immunosorbent assay.
No serious AEs were reported within the 28-day safety follow-up period following any vaccination. Although a higher percentage of subjects reported injection-site AEs after receiving zoster vaccine than did placebo recipients, the proportion of subjects reporting systemic clinical AEs was similar in both groups. Zoster vaccine induced a VZV antibody response at 4 weeks post-vaccination. The estimated geometric mean titer (GMT) ratio (vaccine/placebo) was 2.07 (95% CI: 1.48, 2.88). The geometric mean fold-rise (GMFR) from prevaccination to week 4 post-vaccination was 2.1 in zoster vaccine recipients, versus 1.0 in placebo recipients.
In HZ history-positive adults > or = 50 years of age, zoster vaccine: (1) was well tolerated; and (2) significantly boosted the level of VZV antibody from baseline to 4 weeks post-vaccination as measured by GMT and GMFR. These data support the Advisory Committee on Immunization Practices' recommendation for routine zoster vaccination for all immunocompetent persons >/=60 years of age irrespective of HZ history.

- "US Center for Disease Control and Prevention (US CDC) recommended to inoculate herpes zoster vaccine regardless of past history of herpes zoster, because there is risk of recurrence although it is rare, because it is not clear up to when the incidence risk is reduced, and because there is possibility that the patient does not know about the past disease history. In a study which evaluated the safety and the immunogenicity of ZOSTAVAX on those who were over 50 in 2010, there were no major reactions when ZOSTAVAX was inoculated to those who had herpes zoster in the past, and other local or systemic reactions were similar to the results of SPS . Additionally, the antibody titer measured 4 weeks after the vaccination, those who had ZOSTAVAX showed 2.1 times higher before the vaccination and 2.07 times higher than those who had placebo. "

ABSTRACT: Herpes zoster and post-herpetic neuralgia deteriorate the quality of life because of severe pain and complications, and cause considerable social and economic burden of disease. In 2012, herpes zoster vaccine was released in Korea. The efficacy of herpes zoster vaccine is known to be 51.3-66.5% among the aged over 60 and 69.8-72.4% among adults between 50 and 59. It is also known that preventive efficacy is maintained for at least 5 years. Although there can be local reactions such as redness, pain and swelling at the site of injection and systemic reaction such as headache and eruption after herpes zoster vaccination, most of the adverse reactions are minor and disappear within days by themselves. As it is a live vaccine, persons with severe immune-suppression and pregnant women should not be vaccinated with the vaccine. Currently, Korean Society of Infectious Diseases recommended for the aged over 60 to be vaccinated with herpes zoster vaccine by subcutaneous route. In this article, clinical aspects and burden of disease of herpes zoster, efficacy and effects of herpes zoster vaccine, and herpes zoster vaccine recommendation by Korean Society of Infectious Diseases are discussed.

- "They range from the chronically ill residents of nursing home/assisted-living institutions, to the communitydwellers who are highly functional despite history of chronic diseases and/or concurrent clinical conditions  . Many older adults retain the capacity to mount vigorous immune responses as exemplified by their protection from the 2009 pandemic H1N1 influenza [18- 20], and by the indicated efficacy of the varicella zoster vaccine  . There is also mounting evidence that age may no longer be considered a barrier for organ transplantation from the perspective of either the recipient or the donor   . "

ABSTRACT: Studies comparing chronologically "young" versus "old" humans document age-related decline of classical immunological functions. However, older adults aged ≥65 years have very heterogeneous health phenotypes. A significant number of them are functionally independent and are surviving well into their 8(th)-11(th) decade life, observations indicating that aging or old age is not synonymous with immune incompetence. While there are dramatic age-related changes in the immune system, not all of these changes may be considered detrimental. Here, we review evidences for novel immunologic processes that become elaborated with advancing age that complement preserved classical immune functions and promote immune homeostasis later in life. We propose that elaboration such of late life immunologic properties is indicative of beneficial immune remodeling that is an integral component of successful aging, an emerging physiologic construct associated with similar age-related physiologic adaptations underlying maintenance of physical and cognitive function. We suggest that a systems approach integrating immune, physical, and cognitive functions, rather than a strict immunodeficiency-minded approach, will be key towards innovations in clinical interventions to better promote protective immunity and functional independence among the elderly.
