How about two: http://www.ncbi.nlm.nih.gov/entrez/q...&dopt=Citation J Infect Dis. 1996 Nov;174 Suppl 3:S330-4. Efficacy of high-titer live attenuated varicella vaccine in healthy young children. Varis T, Vesikari T. Department of Virology, University of Tampere Medical School, Finland. The efficacy of a high-titer, reformulated varicella vaccine was studied in 513 10- to 30-month-old children. Vaccinees were randomly allocated to 5 groups to receive one of two lots of an original high-titer vaccine, one of two lots of a partially heat-inactivated vaccine, or placebo. Both vaccines were well tolerated. Seroconversion was detected in 100% and 99% of children immunized with the high- and low-titer vaccines, respectively. Sixty-five cases of serologically confirmed varicella-like disease were discovered during follow-up (mean, 29.3 months): 5 in the high-titer vaccine group, 19 in the low-titer vaccine group, and 41 in the placebo group (P or = .005 for each difference). Thus, the protective efficacy http://www.ncbi.nlm.nih.gov/entrez/q...&dopt=Citation Vaccine. 1991 Sep;9(9):643-7. Oka/Merck varicella vaccine in healthy children: final report of a 2-year efficacy study and 7-year follow-up studies. Kuter BJ, Weibel RE, Guess HA, Matthews H, Morton DH, Neff BJ, Provost PJ, Watson BA, Starr SE, Plotkin SA. Department of Clinical Research, Merck Sharp & Dohme Research Laboratories, West Point, PA 19486. A large double-blind, randomized, placebo-controlled trial of live attenuated Oka/Merck varicella vaccine was conducted among healthy children, 1-14 years of age. During the first varicella season, the efficacy of the vaccine among susceptible children was 100%1. During the second varicella season, 22 children were diagnosed with varicella; 21 cases in placebo recipients and one in a vaccine recipient. The overall efficacy of the vaccine through two varicella seasons was 98%. After the code for the study was broken, the original group of vaccine recipients continued to be followed for development of varicella. The estimated proportion of vaccine recipients who remained varicella-free at the end of 7 years was 95%. The 23 cases of varicella that occurred in vaccine recipients over the 7-year period were considerably milder than natural varicella. The average number of lesions was 53, 50% of the children had non-vesicular rashes, and 14% of the children had a temperature greater than or equal to 38.9 degrees C (102 degrees F), oral. The persistence of antibody in a subset of vaccine recipients followed for 6 years was 100%. |
