OBJECTIVE To evaluate immune responses to neoantigen and recall antigens in healthy subjects treated with teriflunomide. METHODS This was a randomized, double-blind, placebo-controlled study. Subjects received oral teriflunomide (70 mg once daily for 5 days followed by 14 mg once daily for 25 days) or placebo for 30 days. Antibody responses were evaluated following rabies vaccination (neoanti...
INTRODUCTION Children in Singapore receive vaccination against hepatitis B virus (HBV) at 0, 1 and 5 or 6 months of age, and vaccination against pertussis, diphtheria, tetanus, and polio at 3, 4 and 5 months of age. Parents often choose to vaccinate with the combined acellular-pertussis-inactivated polio-Hib vaccine (DTPa-IPV/Hib). We investigated whether a combined hexavalent vaccine, DTPa-HBV...
BACKGROUND For healthcare workers, sometimes the conventional hepatitis-B virus (HBV) vaccination schedule might not provide seroconversion rapidly enough. The aim of this study was to compare the efficacy of conventional HBV vaccination with an accelerated schedule (days 0-1-21). MATERIALS AND METHODS In this randomized clinical trial, 161 healthcare workers were divided into two vaccination...
I read with interest the article by Stief et al. published in your journal recently1. It showed us that hepatitis B virus (HBV) infection remains a significant problem in prisons, and it was related with other published studies2,3. The finding on higher prevalence of HBV infection in the male gender and in prisoners with positive history of intravenous drug use and STD demonstrated a new strate...
BACKGROUND & OBJECTIVES MMR vaccine in a two dose schedule has successfully eliminated measles, mumps and rubella from many developed countries. In India, it is not a part of national immunization programme but is included in the State immunization programme of Delhi as a single dose between 15-18 months. This prospective study was carried out to assess the extent of seroprotection against thes...
Thimerosal, which is approximately 50% mercury by weight is a preservative widely used in vaccines since the 1930's. It meets the requirements for a preservative as set forth by Pharmacopeia challenge test and has been shown to be effective against a broad spectrum of pathogens. In July 1999, the Public Health Service agencies and vaccine manufacturers agreed that thimerosal should be reduced o...
BACKGROUND Little is known about duration of protection after the infant primary series of hepatitis B (HB) vaccine in settings of low HB endemicity. This study sought to determine the proportion of adolescents immunized as infants who had protective titers of antibody to hepatitis B surface antigen (anti-HBs) before and after a challenge dose of vaccine. METHODS US-born 16- through 19-year-o...
Background The live-attenuated Japanese encephalitis (JE) vaccine (JE-CV; IMOJEV) induces a protective response in children. A shift in circulating JE virus strains suggests that a genotype shift phenomenon may occur throughout Southeast Asia. We assessed the neutralization of wild-type (WT) JE virus isolates at distal time points after vaccination. Methods We analyzed serum samples from a su...
We aimed to compare the immune response induced by natural infection with 2009 pandemic influenza A/H1N1 (pH1N1) virus and by monovalent pH1N1 vaccination in children and adolescents. This cross-sectional clinical study was conducted at 3 hospitals in Korea from February to May 2010. A total of 266 healthy subjects aged from 6 months to 18 yr were tested for the presence of the antibody against...
AIM To assess the long-term effectiveness of hepatitis B virus vaccine and the need for a booster dose among children who received three doses of vaccine during infancy in Red Sea Governorate. METHODS A cross-sectional study was performed. Interviews with children (9 months to 16 years) and parents were done. Blood samples to assess Hepatitis B markers were tested. Children showing no seropro...
