The blood samples were kept cold and transported within a couple of hours to the Matlab hospital laboratory, where plasma was immediately separated and stored at -70[degrees] C until transported frozen to the Dhaka laboratory for the analysis of total immunoglobulins (IgG, IgE, and IgA) and C-reactive protein in preimmunization
plasma and MMR vaccine-specific plasma IgG in preand postimmunization plasma.
Among persons with preimmunization
titers of <1:4, most had hSBA titers of [greater than or equal to]1:4 at 1 month after the second dose (13/13 for Bexsero  and 9/10 for Trumenba).
Evaluation of the protective capacity of new mild Citrus tristeza virus (CTV) isolates selected for a preimmunization
epidemiology of hepatitis B virus infection in South African children.
Compared with individuals born in the preimmunization
era, children who develop hepatitis B infection despite immunization are at higher risk of developing hepatocellular carcinoma, the investigators noted.
Blood samples were obtained from each bird preimmunization
, at 7 d after primary immunization, and at 4, 7, 10, 18, 32, and 63 d after secondary immunization.
(immediately before vaccination) and post-immunization (up to 24 hours after delivery) blood samples, with a minimum interval of three weeks between pre and post-immunization samples, were collected from 57 pregnant women (28 MN and 29 C).
3 mg/L or a 4-fold increase above the preimmunization
concentration for at least 5 of the 9 serotypes (7).
In all dilutions used, the absorbances obtained for post-immunization IgY exceeded that of preimmunization
The definitive method is immunizing with specific antigens and assessing preimmunization
Since many of the exposures in this review were attributed to domestic animals, strong local animal control activities should be supported, including removal of strays and adherence to leash laws (for cats as well as dogs), animal bite prevention education, and preimmunization
of persons at high risk for rabies exposure.
In the late 1980s there was a partial resurgence, but at a much lower incidence level than had characterized the preimmunization
