Antibody Response to Live Attenuated Vaccines in Adults in Japan
نویسندگان
چکیده
The purpose of this study was to examine the efficacy rendered with a single dose of live attenuated measles, rubella, mumps, and varicella containing vaccine. We inoculated healthcare workers (HCWs) with a single dose of vaccine to a disease lacking in antibody titer for those not meeting the criteria of our hospital (measles: <16.0 (IgG enzyme immunoassay (EIA)), rubella: ≤1:32 (hemagglutination-inhibition), mumps: <4.0 (IgG EIA), and varicella: <4.0 (IgG EIA)). At 28-60 days after vaccination, the antibody titer was tested again. We included 48 HCWs. A total of 32, 15, 31, and 10 individuals were inoculated with a single dose of measles-containing, rubella-containing, mumps, or varicella vaccine, respectively, and showed significant antibody elevation (9.2 ± 12.3 to 27.6 ± 215.6, p<0.001; 8 ± 1.2 to 32 ± 65.5, p<0.001; 3.0 ± 1.0 to 13.1 ± 8.6, p<0.05; and 2.6 ± 1.3 to 11.8 ± 8.1, p<0.001, respectively). Major side effects were not observed. In a limited population, a single dose of live attenuated vaccine showed elevation of antibody titer without any severe adverse reactions. However, whether the post-vaccination response rate criteria of our university was fulfilled could not be determined owing to limited sample size.

In the present study, 360 male day-old broiler chicks were used to determine the effect of mixed livevaccines of Newcastle disease (ND) and infectious bronchitis (IB) on serum and local antibody responses toIB. Chicks were randomly divided into 12 treatment groups of 3 replicates and reared for 40 days on floorpens. Groups 1 to 5 received mixed ND and IB vaccine. Groups 7 to 11 received IB vacc...

Background and Aims: Prevention of Lumpy skin disease (LSD) in cattle is heavily dependent on vaccination. Since the genetic structure of LSD virus has the close relatedness with other Capri-pox virus (CaPV). Therefore, the use of vaccine strains of CaPV derived from sheep and goat would be useful to protect cattle against LSD. Materials and Methods: The susceptible calves of dairy farms were ...
