Fifteen infants with pneumonia caused by respiratory syncytial virus (RSV) and 19 infants with bronchiolitis caused by RSV were studied for the influence of homologous, circulating neutralizing antibody on the severity of their illness. All infants were under nine months of age. Although maternal neutralizing antibody did not prevent infection with RSV and(More)
Three variants of the immunoenzymometric assay of human lysozyme with HRP-labeled antibodies were compared. The highest sensitivity (with a detection limit of 0.2 micrograms lysozyme/L) was achieved by a one-step assay lasting 2 h. Between-batch precision for the techniques was 6-11%. Lysozyme reference values were determined in serum, cerebrospinal fluid(More)
Thirty-seven healthy volunteers who received a pneumococcal polysaccharide vaccine were tested 4, 5, or 6 years after immunization for circulating type-specific pneumococcal antibody by radioimmunoassay of their sera. Each volunteer was immunized with one of four different pneumococcal vaccines containing 50 micrograms of each of 6, 8, 9, or 13 capsular(More)
Pneumococcal antibody responses and adverse reactions were assessed in 12 healthy volunteers who received either two (10 volunteers) or three (2 volunteers) doses of pneumococcal polysaccharide vaccines at 1 or 2 year intervals. The volunteers were given hexavalent (types 1, 3, 4, 7F, 8, 12F) octavalent (types 14, 19F added) nonavalent (type 5 added), and(More)
The authors investigated the persistence of anticapsular pneumococcal antibodies in 21 subjects one decade after administration of a single dose of a polyvalent pneumococcal polysaccharide vaccine. Fourteen vaccinees received a hexavalent vaccine composed of the polysaccharides of capsular types 1, 3, 4, 7F, 8, and 12F; four vaccinees received an octavalent(More)
