Vaccine AND side effects

Hironori Nakagami, Ryuichi Morishita
PURPOSE OF REVIEW: Vaccines are commonly used as preventive methods, primarily against infectious diseases. The goal of our study is to develop the therapeutic vaccine for hypertension. RECENT FINDINGS: We and others recently reported that an angiotensin II (AngII) vaccine for hypertension successfully attenuated elevated blood pressures in an animal model without any immunogenic side effects. In this system, an immunogenic molecule (i.e., KLH) with adjuvants provides an antigen that supports the activation of helper T cells...

In Italy, the phenomenon of vaccine hesitancy has increased with time and represents a complex problem that requires a continuous monitoring. Misinformation on media and social media seems to be one of the determinants of the vaccine hesitancy since, for instance, 42.8 percent of Italian citizens used the internet to obtain vaccine information in 2016. This article reports a quantitative analysis of 560 YouTube videos related to the link between vaccines and autism or other serious side effects on children...

BACKGROUND: Clonorchiasis caused by Clonorchis sinensis has become increasingly prevalent in recent years. Effective prevention strategies are urgently needed to control this food-borne infectious disease. Previous studies indicated that paramyosin of C. sinensis (CsPmy) is a potential vaccine candidate. METHODS: We constructed a recombinant plasmid of PEB03-CotC-CsPmy, transformed it into Bacillus subtilis WB600 strain (B.s-CotC-CsPmy), and confirmed CsPmy expression on the spore surface by SDS-PAGE, Western blotting and immunofluorescence assay...

A key goal of a successful vaccine formulation is the strong induction of persistent protective immune responses without producing side-effects. Adjuvants have been proved to be successful in several species at inducing increased immune responses against poorly immunogenic antigens. Fish are not the exception and promising results of adjuvanted vaccine formulations in many species are needed. In this study, over a period of 300 days, we characterized the apparent damage and immune response in gilthead seabream immunized by intraperitoneal injection with the model antigen keyhole limpet hemocyanin (KLH) alone or formulated with Montanide ISA water-in-oil (761 or 763), or Imject™ aluminum hydroxide (aluminium), as adjuvants...

The Italian Parliament has recently introduced 10 mandatory immunisations, including the one against varicella. For this vaccination, the obligation starts with the birth cohort of 2017, but it is offered free of charge to subjects with a negative history and not previously vaccinated. This paper presents up-to-date evidence on this issue and illustrates a number of critical arguments that may question the opportunity of this choice. Particularly, while the disease is relatively mild in children aged between 1 and 9 years, the risk of worsening its consequences is progressive with age, becoming worst in the elderly, so the vaccination of children may increase the age of the cases...

Healthcare workers (HCWs) at an Australian cancer centre were evaluated using a voluntary declination form program to determine factors contributing to declination of annual influenza vaccination. Overall, 1835/2041 HCWs (89.9%) completed a consent or declination form; 1783 were vaccinated and 52 declined. Staff roles with minimal patient contact were significantly associated with lower vaccine uptake (adjusted odds ratio 0.48, 95% confidence interval 0.23-0.99). Reasons for vaccine refusal included personal choice (41%), previous side-effect/s (23...

BACKGROUND: The goal of this study was to apply the varicella zoster virus (VZV) vaccine to patients with pediatric rheumatic diseases (PRD) at risk for severe chickenpox, without interrupting their current immunosuppression, including biological agents, using an immunological-based pre-vaccination checklist to assure safety. A pre-vaccination checklist was implemented to ensure adequate immune competence prior to immunization. METHODS: This prospective study included seronegative patients (VZV-IgG ≤200 mIU/ml) and patients who had previously received only a single dose of VZV vaccine...

Drug delivery is a rapidly growing area of research motivated by the nanotechnology revolution, the ideal of personalized medicine, and the desire to reduce the side effects of toxic anti-cancer drugs. Amongst a bewildering array of different nanostructures and nanocarriers, those examples that are fundamentally bio-inspired and derived from natural sources are particularly preferred. Delivery of vaccines is also an active area of research in this field. Bacterial cells and their components that have been used for drug delivery, include the crystalline cell-surface layer known as "S-layer", bacterial ghosts, bacterial outer membrane vesicles, and bacterial products or derivatives (e...

The increased use of vaccination has led to a significant decrease or even to the disappearance of serious infectious diseases. Currently, vaccines are often evaluated by their potential side effects while ignoring the benefits. This happens because of memory loss. The memory of the damage caused by vaccine-preventable diseases has been lost. This paper illustrates the epidemiology of the major vaccine-preventable diseases and the risk of reintroduction of many pathologies in case the vaccine coverage continues to decrease...

OBJECTIVES: To improve information for patients and to facilitate a vaccination coverage that is in line with the EU and World Health Organization goals, we aimed to quantify how vaccination and patient characteristics impact on influenza vaccination uptake of elderly people. METHODS: An online discrete choice experiment (DCE) was conducted among 1261 representatives of the Dutch general population aged 60 years or older. In the DCE, we used influenza vaccination scenarios based on five vaccination characteristics: effectiveness, risk of severe side effects, risk of mild side effects, protection duration, and absorption time...

BACKGROUND: Human Immuno deficiency Virus (HIV) infection has attained pandemic level due to its complexity on both the HIV infection cycle and on the targets for drug delivery. This limits medication and consequently requires prominent and promising drug delivery systems to be invented. Notably, various nanomaterial have been studied to enhance effective delivery of the antiretroviral drugs for HIV prevention, diagnosis and cure. Some of these nanomaterials are liposomes, dendrimers, inorganic nanoparticles (NPs), polymeric micelles, natural and synthetic polymers...

Tumor microenvironment (TME) is characterized by multiple immune suppressive mechanisms able to suppress anti-tumor effector cell immunity. Combinatorial strategies, including vaccine and immunomodulatory drugs, need to be developed for improved immunotherapy efficacy. A novel combinatorial approach was assessed in C57BL/6 mice injected with mouse melanoma B16F10 cells. A multi-peptide vaccine (PEPT) was combined with a low dose metronomic chemotherapy (MCT) and an anti-PD-1 checkpoint inhibitor (CI). Statistical analysis were performed with the unpaired two-sided Student's t-test and ANOVA...

Dickkopf-1 (DKK1) is an ideal target for the immunotherapy of multiple myeloma. Heat Shock protein70 (HSP70) is a class of important molecular chaperone to promote antigen presentation. Homologous xenogeneic antigens can enhance immunogenicity and induce stronger anti-tumor immune response than that of allogeneic ones. Therefore, we constructed human DKK1 and human HSP70 DNA fusion vaccine (hDKK1-hHSP70), and then determined its anti-tumor immuno- genicity and anti-tumor effects on immunizing BALB/c mice already inoculated with NS-1 murine multiple myeloma cells in prophylactic and therapeutic models using cytotoxic T lymphocytes, enzyme-lined immunosorbent assay, flow cytometry, immunohistochemistry and Hochest staining...

Vaccines typically come with adjuvants that trigger the innate immune system in order to prepare best possible inflammatory conditions as to allow the adaptive immune system to become activated, generally for the induction of antibodies. The oldest approved and most abundant immunological adjuvants are salts of aluminium, which are also frequently used in animal models of immunisation and allergy desensitization. In rodents, the intraperitoneal administration of aluminium adjuvants is commonly performed and considered safe...

Herbal remedies were the first medicines used by humans due to the many pharmacologically active secondary metabolites produced by plants. Some of these metabolites inhibit cell division and can therefore be used for the treatment of cancer, e.g. the mitostatic drug paclitaxel (Taxol). The ability of plants to produce medicines targeting cancer has expanded due to the advent of genetic engineering, particularly in recent years because of the development of gene editing systems such as the CRISPR/Cas9 platform...

Overexpression of human epidermal growth factor receptor-2 (HER2) occurs in 20-30% of invasive breast cancers. Monoclonal antibody therapy is effective in treating HER2-driven mammary carcinomas, but its utility is limited by high costs, side effects and development of resistance. Active vaccination may represent a safer, more effective and cheaper alternative, although the induction of strong and durable autoantibody responses is hampered by immune-tolerogenic mechanisms. Using a novel virus-like particle (VLP) based vaccine platform we show that directional, high-density display of human HER2 on the surface of VLPs, allows induction of therapeutically potent anti-HER2 autoantibody responses...

Antitumor conventional treatments including chemo/radiotherapy result in several side effects and non-specificity. Therapies including the use of oncolytic viruses, particularly the Newcastle disease virus (NDV), have emerged as an attractive alternative due to their capacity to kill cancer cells directly or through stimulation of the immune system. In the present study, a commercial vaccine composed of a recombinant attenuated NDV strain P05 (rNDV-P05) was assessed for antitumor and immunostimulatory activity...
