Despite its proven efficacy, the hepatitis B vaccine requires improvements in immune enhancement and durability, especially in the elderly. Levamisole, an immune modulator, has been tested as an adjuvant to hepatitis B vaccine in several studies in immune-compromised populations. However, we aimed to evaluate the effect of levamisole on the immune response to hepatitis B vaccine in healthy subjects. In this randomized clinical trial, healthy family members of chronic hepatitis B patients were given twenty-microgram intramuscular injections of hepatitis B vaccine at 0, 1, and 6 months and 50 miligrams of oral  levamisole twice a day for two weeks with every vaccination dose...

REVIEW
Mansi Saxena, Nina Bhardwaj
Development of therapeutic cancer vaccines has been hindered by the many pro-tumorigenic mechanisms at play in cancer patients that serve to suppress both antigen presenting cells and T cells. In face of these obstacles, cancer vaccines are most likely to promote anti-tumorigenic immune responses only when formulated with strong adjuvants, and in combination with new immune interventions designed to reverse immune suppression and exhaustion of T cells in the tumor microenvironment. Dendritic cells (DCs) are often termed 'nature's adjuvant' due to their exceptional capacity for initiating both innate and adaptive immune responses...

Human enterovirus 71 (EV71) is a major causative pathogen of hand, foot and mouth disease (HFMD) and has caused outbreaks with significant mortality among young children in the Asia-Pacific region in recent years. Towards developing a vaccine for this disease, we have expressed and purified EV71 virus-like particles (VLPs), which resemble the authentic virus in appearance, capsid structure and protein sequence, from insect cells (Sf9) using a multistep chromatography process. We demonstrated intracellular localization of the VLPs in host cells by in situ immunogold detection, electron microscopy and immunofluorescence...

T-cell based vaccines have been considered as attractive candidates for prevention of hepatitis C virus (HCV) infections. In this study we compared the magnitude and phenotypic characteristics of CD8+ T-cells induced by three commonly used viral vectors, Adenovirus-5 (Ad5), Vaccinia virus (VV) and Modified Vaccinia Ankara (MVA) expressing the HCV NS3/4A protein. C57/BL6 mice were primed with DNA expressing NS3/4A and boosted with each of the viral vectors in individual groups of mice. We then tracked the vaccine-induced CD8+ T-cell responses using pentamer binding and cytokine production analysis...

The ability to control lentivirus replication may be determined, in part, by the extent to which individual viral proteins are targeted by the immune system. Consequently, defining the antigens that elicit the most protective immune responses may facilitate the design of effective HIV-1 vaccines. Here we vaccinated four groups of rhesus macaques with a heterologous vector prime/boost/boost/boost (PBBB) regimen expressing the following simian immunodeficiency virus (SIV) genes: env, gag, vif, rev, tat, and nef (Group 1); env, vif, rev, tat, and nef (Group 2); gag, vif, rev, tat, and nef (Group 3); or vif, rev, tat, and nef (Group 4)...

PURPOSE OF REVIEW: The review highlights the shift from prescribed length of stay (LOS) to mother-infant dyad readiness as the basis for making discharge decisions for healthy term newborns. We describe the components of readiness that should be considered in making the decision, focusing on infant clinical readiness, and maternal and familial readiness. RECENT FINDINGS: Although the Newborns' and Mothers' Health Protection Act of 1996 aimed to protect infants and mothers by establishing a minimum LOS, the American Academy of Pediatrics 2015 policy on newborn discharge acknowledges the shift from LOS-based to readiness-based discharge decision-making...

PURPOSE OF REVIEW: Great progress has been made in reducing malaria morbidity and mortality, yet the parasite continues to cause a startling 200 million infections and 500 000 deaths annually. Malaria vaccine development is pushing new boundaries by steady advancement toward a licensed product. RECENT FINDINGS: Despite 50 years of research, the complexity of Plasmoidum falciparum confounds all attempts to eradicate the organism. This very complexity has pushed the boundaries of vaccine development to new heights, yet it remains to be seen if an affordable vaccine can provide durable and high-level protection...

OBJECTIVE: Persistent infection with oncogenic high risk HPV (hrHPV) types causes virtually all cases of cervical cancer. HPV 16 and 18 have been targeted for individual genotyping and vaccination because of their presence in 71% of invasive cervical cancers worldwide. Montefiore Medical Center, Bronx, New York serves a population known for ethnic and racial diversity. Given this diversity it is possible that HPV genotypes not individually detected by current testing are causing significant disease...

Advances in the knowledge of various roles played by non-coding RNAs have stimulated the application of RNA molecules as therapeutics. Among these molecules, miRNA, siRNA, and CRISPR-Cas9 associated gRNA have been identified as the most potent RNA molecule classes with diverse therapeutic applications. One of the major limitations of RNA-based therapeutics is immunotoxicity of RNA molecules as it may induce the innate immune system. In contrast, RNA molecules that are potent immunostimulators are strong candidates for use in vaccine adjuvants...

Influenza vaccination is the best measure available to prevent seasonal influenza infection. The majority of studies on vaccine effectiveness in the 2015/16 season conducted in the European I-MOVE+ Project, show that a match between the circulating influenza strains in the general public and those included in the vaccine for the Northern Hemisphere was low to moderate. As part of I-MOVE+, Poland has implemented a case control negative study design and molecular biology methods, such as real time RT-PCR, to assess the vaccine match and effectiveness...

Pediatric patients suffering from cancer are at risk of hepatitis B virus (HBV) infection and its related complications even though it is considered a vaccine preventable disease. Little is known of the effects of chemotherapy, and even less is known regarding the impact of HBV booster on HBV antibody titers. It is the purpose of this study to investigate and measure the prevalence of the antihepatitis B surface antibodies (HBsAb) in childhood cancer survivors after completion of their chemotherapy treatment and to further evaluate survivors' response to a single booster dose of HBV vaccine...
