| rubella antibody persistence after immunization. | a comparative field trial of three live, attenuated rubella virus vaccines (cendehill, hpv 77 de-5, and hpv-77 dk-12) was initiated in 1969 on the islands of kauai and hawaii in the state of hawaii. following initial seroconversion rates of more than 98%, periodic serological testing of the study population was conducted to assess the durability of vaccine-induced immunity. in february 1980, ten years after the initiation of the study, 741 of the 5,153 original susceptible vaccinees were still e ... | 1982 | 7053457 |
| rubella immunization. persistence of antibody four years after a large-scale field trial. | a long-term comparative field trial of three live, attenuated rubella vaccines (hpv-77 de-5, hpv-77 dk-12, and cendehill) was initiated in 1969 on the islands of kauai and hawaii in the state of hawaii. rubella hemagglutination-inhibition (hi) tests on prevaccination serum specimens from 7,931 children in the two study areas indicated an overall susceptibility to rubella of nearly 70%. the rates of seroconversion of 5,153 seronegative subjects to hpv-77 de-5, hpv-77 dk-12, and cendehill vaccine ... | 1976 | 946844 |
| rubella antibody persistence after immunization. sixteen-year follow-up in the hawaiian islands. | a comparative field trial of three rubella virus vaccines (cendehill, hpv-77 de-5, and hpv-77 dk-12) was initiated in 1969 on the islands of kauai and hawaii in the state of hawaii. in 1985, follow-up was reinitiated to assess the long-term durability of vaccine-induced immunity. enzyme-linked immunosorbent assays of serum specimens from 1290 participants demonstrated seropositive rates of 92.4% and 96.4% at screening levels of 10 (protective level) and 7 (lowest detectable level) iu/ml, respect ... | 1988 | 3367488 |
