Resolution of Chlamydia trachomatis Infection Is Associated with a Distinct T Cell Response Profile.

Chlamydia trachomatis is the causative agent of the most frequently reported bacterial sexually transmitted infection, the total burden of which is underestimated due to the asymptomatic nature of the infection. Untreated C. trachomatis infections can cause significant morbidities, including pelvic inflammatory disease and tubal factor infertility (TFI).

Efficacy of a monovalent human-bovine (116E) rotavirus vaccine in Indian children in the second year of life.

Unlabelled: Rotavirus gastroenteritis is one of the leading causes of diarrhea in Indian children less than 2 years of age. The 116E rotavirus strain was developed as part of the Indo-US Vaccine Action Program and has undergone efficacy trials. This paper reports the efficacy and additional safety data in children up to 2 years of age.

Efficacy of a monovalent human-bovine (116E) rotavirus vaccine in Indian infants: a randomised, double-blind, placebo-controlled trial.

Background: Rotavirus is the most common cause of severe dehydrating gastroenteritis in developing countries. Safe, effective, and affordable rotavirus vaccines are needed in these countries. We aimed to assess the efficacy and tolerability of a monovalent human-bovine rotavirus vaccine for severe rotavirus gastroenteritis in low-resource urban and rural settings in India.

Evaluation of safety and immunogenicity of recombinant influenza hemagglutinin (H5/Indonesia/05/2005) formulated with and without a stable oil-in-water emulsion containing glucopyranosyl-lipid A (SE+GLA) adjuvant.

Background: Expression of recombinant hemagglutinin (rHA) in insect cells represents a technology with proven efficacy in seasonal influenza and with the potential for a rapid response to the emergence of new, pandemic strains. We evaluated the safety and immunogenicity of rHA vaccine (H5/Indonesia/5/05) produced in SF+ insect cells using a baculovirus expression vector system (BEVS). The rHA vaccine was tested with and without the adjuvant glucopyranosyl lipid A/stable emulsion (GLA/SE).

Anthrax vaccine-induced antibodies provide cross-species prediction of survival to aerosol challenge.

Because clinical trials to assess the efficacy of vaccines against anthrax are not ethical or feasible, licensure for new anthrax vaccines will likely involve the Food and Drug Administration's "Animal Rule," a set of regulations that allow approval of products based on efficacy data only in animals combined with immunogenicity and safety data in animals and humans.
