Background: Meningococcal disease remains an important public health problem globally. We assessed the non-inferiority and the lot-to-lot consistency of a pentavalent meningococcal ACYWX conjugate vaccine (NmCV-5; Serum Institute of India, Pune, India) versus a quadrivalent meningococcal ACWY conjugate vaccine (MenACWY-D) in healthy adults.

Methods: In this observer-blind, randomised, active-controlled, phase 2/3 study, healthy adults aged 18-85 years were recruited from nine hospitals across seven cities in India.

Article Synopsis
  • The Rapid Fluorescence Focus Inhibition Test (RFFIT) measures the potency of rabies monoclonal antibodies, but is time-consuming and requires specialized facilities and trained personnel.
  • The World Health Organization has encouraged the development of alternative methods, leading to the creation of an In-vitro ELISA test that uses inactivated rabies vaccine to quantify antibody potency.
  • This new ELISA test is validated for accuracy and sensitivity, easy to perform, cost-effective, and can be conducted without the need for specialized labs, providing results in just a few hours.

Current postexposure prophylaxis of rabies includes vaccines, human rabies immunoglobulin (RIG), equine RIG, and recombinant monoclonal antibodies (mAb). In the manufacturing of rabies recombinant mAb, charge variants are the most common source of heterogeneity. Charge variants of rabies mAb were isolated by salt gradient cation exchange chromatography (CEX) to separate acidic and basic and main charge variants.

Background: Enteric fever caused by Salmonella enterica Typhi and Salmonella Paratyphi A is an important public health problem, especially in low-income and middle-income countries with limited access to safe water and sanitation. We present results from, to our knowledge, the first ever human study of a bivalent paratyphoid A-typhoid conjugate vaccine (Sii-PTCV).

Methods: In this double-blind phase 1 study, 60 healthy Indian adults were randomly assigned (1:1) to receive a single intramuscular dose of either Sii-PTCV or typhoid conjugate vaccine (Typbar-TCV).

Background: Dengue is highly prevalent in Asia and Latin America and has no specific dengue antiviral treatment. A recombinant monoclonal antibody (VIS513) that neutralises all four serotypes of the dengue virus has been developed in India. After confirmation of safety and efficacy in preclinical studies, it was tested in a first-in-human study to assess the safety and pharmacokinetics.
