Filter by:The purpose of this study is to observe the occurrence of adverse events, seroconversion rate and geometric mean titres(GMTs) of 2 doses of live attenuated varicella vaccine.
This study will evaluate the immunogenicity, safety, and tolerability of VARIVAX™ (Varicella Virus Vaccine Live) manufactured with a New Seed Process (NSP) compared with the VARIVAX™ 2007 process. The primary hypotheses being tested are that antibody response rate and mean antibody titer induced at 6 weeks after a single vaccination by VARIVAX™ NSP are non-inferior to those induced by VARIVAX™ 2007 process, and that antibody response rate induced by VARIVAX™ NSP is acceptable.
It is a clinicaltrial Phase III , randomized, double -blind , 4-arm (390 each one): This study will include 1560 children and will use 3 batches of vaccine produced by Bio - Manguinhos with viral bulk of GSK combined measles , mumps and rubella applied in healthy children 12-15 months of age, and 01 batch of MMR to reference( GSK ), applied in healthy children aged 12-15 months old . The vaccine is administered as MMR 1st dose. Two hypotheses are tested : 1. Consistency of production ( equivalence between batches )of 3 batches of vacines(TV1, TV2 , TV3 Bio- Manguinhos). Noninferiority vaccine Bio TV (Fiocruz, Rio de Janeiro), ie, the measles, mumps and rubella in Brazil is as immunogenic and safe as the measles, mumps and rubella reference, already used in routine NIP (production Bio-Manguinhos/FIOCRUZ with viral concentrate, bulk, GSK). The MMR vaccine (Bio-TV) will have the same composition (vaccine strains) and the same method of production of MMR (TV-GSK): Wistar RA27 / 3 rubella, Schwarz strain of measles vaccine, and strain RIT 4385 - derived from the Jeryl Lynn strain of mumps vaccine. As 2nd dose, children receive the vaccine tetraviral measles-mumps-rubella-varicella, aged 15-18 months, according to the guidance of the National Immunization Program. 2. Noninferiority vaccine Bio TV (Fiocruz, Rio de Janeiro):the measles, mumps and rubella vaccine in Brazil is as immunogenic and safe as the measles, mumps and rubella reference, already used in routine NIP (production Bio-Manguinhos/FIOCRUZ with viral concentrate, bulk, GSK). Returns for blood sampling will be scheduled for 51 days, ranging from 42 to 60 days after dose of MMR vaccine dose and after tetraviral. We will colect the firt blood sample before the first vaccination too. It will describe the major adverse events observed after vaccination , comparing their frequency in groups of MMR vaccine with the Brazilian reference vaccine .
This study will compare the safety, tolerability, and immunogenicity of measles, mumps, rubella, and varicella (MMRV) vaccine made with an alternative manufacturing process with those of the 2006 process
The purpose of this study is to assess the immunogenicity and safety of GSK Biologicals' investigational measles, mumps, rubella and varicella (MMRV) vaccine (GSK208136, PriorixTetra™) when co-administered along with conjugated Meningococcal C (MenC) vaccine (Meningitec®, Nuron Biotechs' Vaccine) in healthy children.
The purpose of this post-marketing surveillance study is to collect and assess information on safety and efficacy of valaciclovir in pediatric patients with chickenpox
The aim of the study is to investigate the memory immune response and the yearly persistence of the immunity against Japanese Encephalitis (JE) after vaccination with Japanese Encephalitis Chimeric Virus Vaccine (JE-CV) in participants previously vaccinated with JE-CV vaccine. Objectives: - To describe JE immune status before and after JE-CV vaccination in subjects previously vaccinated with JE-CV vaccine - To describe the immune status before and after JE-CV vaccination in JE-naïve control subjects. - To describe the safety (in terms of solicited and unsolicited adverse events) of a single dose of JE-CV vaccine up to 6 months after the last vaccination. - To describe all related serious adverse events (SAEs) and related deaths from 6 months to 5 years after vaccination in JE-CV-primed subjects.
The purpose of these continuing post-licensure studies is to evaluate the long-term effectiveness of VARIVAX® [Varicella Virus Vaccine Live (Oka/Merck)] and to assess the impact of the vaccine on the epidemiology of varicella and herpes zoster.
This survey is conducted for preparing application materials for re-examination under the Korean Pharmaceutical Affairs Laws and its Enforcement Regulation; its aim is to reconfirm the clinical usefulness of VARIVAX through collecting the safety information according to the Re-examination Regulation for New Drugs.
A Study comparing three different doses of ProQuad to concomitant administration of M-M-R II and PUVV (Process Upgrade Varicella Vaccine) vaccines.
