Respiratory syncytial virus (RSV) is the most common cause of serious acute lower respiratory illness in infants and young children and a significant cause of disease burden in the elderly and immunocompromised. There are no licensed RSV vaccines to address this significant public health need. While advances in vaccine technologies have led to a recent resurgence in RSV vaccine development, the immune...
Respiratory viral infections in infants and young children frequently cause illness that can easily progress to hospitalization and death. There are currently no licensed vaccines to prevent respiratory viral disease in children younger than 6 months, reflecting safety concerns and the difficulty in inducing effective immune responses in infants. This review discusses vaccines that have been developed,...
The prevalence of antibodies to measles, mumps, and rubella in US military recruits is of importance to public health leaders. We performed ELISA testing using a commercially available product on samples from 537 recruits obtained in 1998, of which 437 were positive (81%). We then performed a validation study in a subsample of the population using plaque reduction neutralization (PRN) to assess misclassification...
Aerosol measles vaccination has been found to be more immunogenic than subcutaneous administration as a booster in school aged children, and immunogenic in 12-month-old children as a primary dose. The objective of the study was to evaluate immunogenicity to aerosol measles vaccine in 9-month-old children.Nine-months-old infants received Edmonston-Zagreb measles vaccine by aerosol (10 3.58 ...
A recombinant human antibody fragment, designated RSV Fab 19, efficiently neutralizes respiratory syncytial virus (RSV). Here we report the results of our sequence analysis of antibody escape mutants that identified F glycoprotein amino acids critical for binding of human or murine RSV F-neutralizing antibodies.
To study the kinetics of humoral as well as cellular immunity to measles and to test for associated immunosuppression 124 12 month old children were studied twice, before routine MMR and either 14, 22, 30, or 38 days after vaccination. Plaque reduction neutralization (PRN) titres were determined at these time points and lymphocytes were evaluated to identify changes in proportions of phenotype, their...
