Title: Identification of rubella virus T-cell epitopes recognized in anamnestic response to RA27/3 vaccine: associations with boost in neutralizing antibody titer. Author: Mitchell LA, Tingle AJ, Décarie D, Shukin R. Journal: Vaccine; 1999 May 14; 17(19):2356-65. PubMed ID: 10392617. Abstract: Rubella virus (RV)-specific cell-mediated immunity (CMI) and antibodies were measured in healthy adolescents reimmunized with measles-mumps-rubella (MMR) vaccine. Lymphocyte proliferation to RV synthetic peptides was determined before and at 2, 4 and 10 weeks after, MMR. After MMR, increased CMI was observed with 16 peptides, including six containing antibody neutralization (NT) domains. Positive CMI (stimulation index > or =2.0) to E1(254-285) and C(1-29) before vaccination was significantly associated with a boost in NT titers, while positive CMI at weeks 2 or 4 to E1(254-285), E1(301-314), E1(389-408), E1(462-481), E2(134-150), E2(140-156), E2(168-179), C(1-29) and C(88-111) showed the same association.[Abstract] [Full Text] [Related] [New Search]
