Abstract
Difference in antibody responses between varicella and herpes zoster was reconfirmed by complement fixation (CF) test and by platelet aggregation (PA) test. Rise in PA antibody level was observed only in patients with herpes zoster, but not in patients with varicella, while the increase in CF antibody was demonstrated in both types of the diseases. Among 235 healthy children, CF antibody was detected in 42 children and out of these 25 also had PA antibody. Sera of 116 individuals who were vaccinated with a live vaccine comprised of varicellaherpes zoster virus (VZV) were tested for CF and PA antibodies. Within six months after vaccination, 81.3 per cent of the vaccinees demonstrated the rise in CF antibody alone, and only one vaccinee possessed low level of PA antibody. Six months to 1 year after vaccination, CF antibody in 12 out of 13 vaccinees fell to undetectable level. Later than 1 year after vaccination, 9 out of 28 vaccinees possessed CF antibody. Two out of these 9 vaccinees also had PA antibody. The PA antigens prepared from viruses isolated either from a varicella patient or a herpes zoster patient responded similarly to the sera of herpes zoster patients, but no response was detected with sera of varicella patients. PA and CF antibody titers of herpes zoster patients showed a high degree of correlation.
