Safety and efficacy results of simulated post-exposure prophylaxis with human immune globulin (HRIG; KEDRAB) co-administered with active vaccine in healthy subjects: a comparative phase 2/3 trial.

We conducted a clinical trial to assess the safety and putative efficacy of an additional human rabies immune globulin (HRIG; KEDRAB) versus an older product (Comparator, HyperRAB S/D® [Grifols]) and determine whether HRIG interferes with development of endogenous antibodies versus Comparator, when each is given with an active rabies vaccine. This was a prospective, double-blind, single-period, non-inferiority study in which subjects were randomized (1:1) to a single dose (20 IU/kg) of HRIG or Comparator o...


Final Analysis of a Trial of M72/AS01 Vaccine to Prevent Tuberculosis.

Results of an earlier analysis of a trial of the M72/AS01 candidate vaccine against showed that in infected adults, the vaccine provided 54.0% protection against active pulmonary tuberculosis disease, without evident safety concerns. We now report the results of the 3-year final analysis of efficacy, safety, and immunogenicity.

Efficacy, safety and immunogenicity of a pneumococcal protein-based vaccine co-administered with 13-valent pneumococcal conjugate vaccine against acute otitis media in young children: A phase IIb randomized study.

Native American populations experience a substantial burden of pneumococcal disease despite use of highly effective pneumococcal conjugate vaccines (PCVs). Protein-based pneumococcal vaccines may extend protection beyond the serotype-specific protection elicited by PCVs.


Partial cross-protection between Japanese encephalitis virus genotype I and III in mice.

Genotype III (GIII) Japanese encephalitis virus (JEV) predominance has gradually been replaced by genotype I (GI) over the last 20 years in many Asian countries. This genotype shift raises concerns about the protective efficacy of Japanese encephalitis (JE) vaccines, as all of the currently licensed JE vaccines are derived from GIII strains. In this study, we conducted vaccination-challenge protection assays to evaluate the cross-protective efficacy of GI- or GIII-derived vaccines against the challenge of a...

Consequence of Hapten Stereochemistry: An Efficacious Methamphetamine Vaccine.

Recent trends in methamphetamine (METH) misuse and overdose suggest society is inadvertently overlooking a brewing METH crisis. In the past decade, psychostimulant-related lethal overdoses and hospitalizations have skyrocketed 127 and 245%, respectively. Unlike the opioid crisis, no pharmaceutical interventions are available for treating METH use disorder or reversing overdose. Herein, we report the first active vaccine that offers protection from lethal (+)-METH challenge in male Swiss Webster mice. This v...

National Outbreak of Pertussis in England, 2011-2012: A Case-control Study Comparing 3-Component and 5-Component Acellular Vaccines With Whole-cell Pertussis Vaccines.

In England, acellular pertussis (aP) vaccines replaced whole-cell pertussis (wP) vaccine in the primary immunization course in October 2004. Despite sustained high vaccine coverage, 10 454 cases were confirmed in England in 2011-2012, including 1648 (16%) in those aged 10-19 years. These individuals had been primed with either 3-component (aP3) or 5-component (aP5) aP vaccines or wP vaccine due to temporary supply shortages. We aimed to compare protection provided by different pertussis vaccines.

Carbon nanotube-based DNA vaccine against koi herpesvirus given by intramuscular injection.

Koi herpesvirus (KHV) also named Cyprinid Herpesvirus 3 (CyHV-3) is one of the most threatening pathogens affecting common carp production as well as the valued ornamental koi carp. The current commercial vaccines available are costly and potentially cause severe stress caused by live virus. KHV ORF149 gene has been proved encoding one of the main immunogenic proteins for KHV. In this study, we coupled a plasmid expression vector for ORF149 to single walled carbon nanotubes (SWCNTs) for an anti-KHV vaccine....

Heterologous prime-boost vaccination against tuberculosis with recombinant Sendai virus and DNA vaccines.

In an earlier study, a novel Sendai virus-vectored anti-tuberculosis vaccine encoding Ag85A and Ag85B (SeV85AB) was constructed and shown to elicit antigen-specific T cell responses and protection against Mycobacterium tuberculosis (Mtb) infection in a murine model. In this study, we evaluate whether the immune responses induced by this novel vaccine might be elevated by a recombinant DNA vaccine expressing the same antigen in a heterologous prime-boost vaccination strategy. The results showed that both SeV...

Genotype-matched Newcastle disease virus vaccine confers improved protection against genotype XII challenge: The importance of cytoplasmic tails in viral replication and vaccine design.

Although typical Newcastle disease virus (NDV) vaccines can prevent mortality, they are not effective in preventing viral shedding. To overcome this, genotype-matched vaccines have been proposed. To date, this approach has never been tested against genotype XII strains. In this study, we generated and assessed the protection against genotype XII challenge of two chimeric NDV vaccine strains (rLS1-XII-1 and rLS1-XII-2). The rLS1-XII-1 virus has the complete fusion protein (F) and the hemagglutinin-neuraminid...

Is a Universal Influenza Virus Vaccine Possible?

Influenza viruses remain a severe burden to human health because of their contribution to overall morbidity and mortality. Current seasonal influenza virus vaccines do not provide sufficient protection to alleviate the annual impact of influenza and cannot confer protection against potentially pandemic influenza viruses. The lack of protection is due to rapid changes of the viral epitopes targeted by the vaccine and the often suboptimal immunogenicity of current immunization strategies. Major efforts to imp...

Beyond memory T cells: mechanisms of protective immunity to Tuberculosis infection.

Tuberculosis (TB) is a serious infectious disease caused by infection with Mycobacterium tuberculosis, and kills more people annually than any other single infectious agent. Although a vaccine is available, it is only moderately effective and an improved vaccine is urgently needed. The ability to develop a more effective vaccine has been thwarted by a lack of understanding of the mechanism of vaccine-induced immune protection. Over recent decades many novel TB vaccines have been developed and almost all hav...

CD4+ T cell cytokine responses to the DAR-901 booster vaccine in BCG-primed adults: A randomized, placebo-controlled trial.

DAR-901 is an inactivated whole cell tuberculosis booster vaccine, prepared using a new scalable, broth-grown method from the master cell bank of SRL172, a vaccine previously shown to prevent tuberculosis. This study examined whether DAR-901 (a) induces CD4+ T cell cytokine profiles previously proposed as correlates of protection and (b) has a specific vaccine-induced immunological signature compared to BCG or placebo.

Vaccine protection against Murid Herpesvirus-4 is maintained when the priming virus lacks known latency genes.

γ-herpesviruses establish latent infections of lymphocytes and drive their proliferation, causing cancers and motivating a search for vaccines. Effective vaccination against Murid Herpesvirus-4 (MuHV-4)-driven lymphoproliferation by latency-impaired mutant viruses suggests that lytic access to the latency reservoir is a viable target for control. However the vaccines retained the immunogenic MuHV-4 M2 latency gene. Here, a strong reduction in challenge virus load - was maintained when it lacked the main la...

A canine vaccine against Leptospira serovars Icterohaemorrhagiae, Canicola and Grippotyphosa provides cross protection against Leptospira serovar Copenhageni.

Efficacy of the Leptospira components of multivalent vaccine DAPPi-L was previously demonstrated against virulent challenge with three serovars of Leptospira interrogans (Canicola, Icterohaemorrhagiae and Grippotyphosa) carried out 14 days after primary vaccination. In this study we demonstrate that this vaccine provides, two weeks after vaccination, an additional protection (prevention of mortality, clinical signs, renal infection, bacterial excretion, renal carriage and renal lesions) against fatal leptos...

Prophylactic Paracetamol After Meningococcal B Vaccination Reduces Postvaccination Fever and Septic Screens in Hospitalized Preterm Infants.

Following the introduction of the 4CMenB (Bexsero, GlaxoSmithKline, Rixensart, Belgium) vaccine against Meningococcal B into the UK vaccination schedule, Public Health England advised paracetamol to be given prophylactically with the vaccine. This was based on observations of increased postvaccination febrile reactions in term infants. Evidence in preterm infants was lacking. We aimed to evaluate whether (i) 4CmenB is associated with an increase in adverse events (AEs) in the 48 hours after vaccination in p...

Enhanced safety and immunogenicity of a psaA mutant whole-cell inactivated pneumococcal vaccine.

Existing capsular polysaccharide-based vaccines against pneumococcal disease are highly effective against vaccine-included serotypes, but they are unable to combat serotype replacement. We have developed a novel pneumococcal vaccine that confers serotype-independent protection, and could therefore constitute a 'universal' vaccine formulation. This preparation is comprised of whole un-encapsulated pneumococci inactivated with gamma-irradiation (generating γ-PN), and we have previously reported induction of ...

Assessment of population immunity to measles in Ontario, Canada: A Canadian Immunization Research Network (CIRN) Study.

Canada eliminated measles in 1998. We conducted a sero-epidemiology study to estimate population immunity to measles in the province of Ontario, Canada and to identify groups at higher risk of outbreaks. We used a previously developed modified enzyme immunoassay to test 1,199 residual sera from patients aged 1-39 years. We re-tested negative and equivocal sera using a plaque reduction neutralization assay. We interpreted our results in the context of Ontario's immunization program and vaccine coverage data....

The Schistosoma mansoni cyclophilin A epitope 107-121 induces a protective immune response against schistosomiasis.

Great efforts have been made to identify promising antigens and vaccine formulations against schistosomiasis. Among the previously described Schistosoma vaccine candidates, cyclophilins comprise an interesting antigen that could be used for vaccine formulations. Cyclophilin A is the target for the cyclosporine A, a drug with schistosomicide activity, and its orthologue from Schistosoma japonicum induces a protective immune response in mice. Although Schistosoma mansoni cyclophilin A also represents a promis...

Serum IgG antibodies to Shigella lipopolysaccharide antigens - a correlate of protection against shigellosis.

Shigella is a leading cause of diarrhea among children globally and of diarrheal deaths among children under 5 years of age in low- and middle-income countries. To date, no licensed Shigella vaccine exists. We review evidence that serum IgG antibodies to Shigella LPS represent a good correlate of protection against shigellosis; this could support the process of development and evaluation of Shigella vaccine candidates. Case-control and cohort studies conducted among Israeli soldiers serving under field cond...

Increase of dose associated with decrease in protection against controlled human malaria infection by PfSPZ Vaccine in Tanzanian adults.

A vaccine would be an ideal tool for reducing malaria's impact. PfSPZ Vaccine (radiation attenuated, aseptic, purified, cryopreserved Plasmodium falciparum [Pf] sporozoites [SPZ]) has been well tolerated and safe in >1,526 malaria-naïve and experienced 6-month to 65-year-olds in the U.S., Europe, and Africa. When vaccine efficacy (VE) of 5 doses of 2.7x105 PfSPZ of PfSPZ Vaccine was assessed in adults against controlled human malaria infection (CHMI) in the U.S. and Tanzania and intense field transmission ...

New vaccines against tuberculosis.

With about 10 million active disease cases and 1.5 million deaths in 2018, tuberculosis (TB) remains one of the most threatening infectious diseases. Yet, the World Health Organization (WHO) aims to reduce morbidity and mortality by 90 and 95%, respectively, between 2015 and 2035. Although diagnostics, therapeutics, and a vaccine are available, it is beyond doubt that better intervention measures are needed to accomplish this ambitious goal. The vaccine bacille Calmette-Guérin (BCG) partially protects ...

Vaccines targeting Staphylococcus aureus skin and bloodstream infections require different composition.

Staphylococcus aureus infections represent a major public health threat, but previous attempts at developing a universal vaccine have been unsuccessful. We attempted to identify a vaccine that would be protective against both skin/soft tissue and bloodstream infections. We first tested a panel of staphylococcal antigens that are conserved across strains, combined with aluminum hydroxide as an adjuvant, for their ability to induce protective immunity in both skin and bacteremia infection models. Antigens wer...

Vaccination With a Single Consensus Envelope Protein Ectodomain Sequence Administered in a Heterologous Regimen Induces Tetravalent Immune Responses and Protection Against Dengue Viruses in Mice.

The development of a safe and effective tetravalent dengue vaccine that elicits protection against all dengue virus (DENV) serotypes is urgently needed. The consensus sequence of the ectodomain of envelope (E) protein of DENV (cE80) has been examined as an immunogen previously. In the current study, a cE80 DNA (D) vaccine was constructed and evaluated in conjunction with the cE80 protein (P) vaccine to examine whether both vaccines used together can further improve the immune responses. The cE80 DNA vaccine...

Vaccination with FAdV-8a induces protection against inclusion body hepatitis caused by homologous and heterologous strains.

Fowl aviadenoviruses (FAdV) are an important avian pathogen, responsible for several poultry diseases prevalent worldwide, including inclusion body hepatitis (IBH). FAdV intraspecies cross-protection has been clearly demonstrated, but there is little evidence that any interspecies cross-protection exists. The present study aimed to assess the inter- and intraspecies protection between three FAdV field isolates (FAdV-8a, FAdV-8b, FAdV-11) identified in association with severe IBH outbreaks. Inoculums prepare...

Restrained expansion of the recall germinal center response as biomarker of protection for influenza vaccination in mice.

Correlates of protection (CoP) are invaluable for iterative vaccine design studies, especially in pursuit of complex vaccines such as a universal influenza vaccine (UFV) where a single antigen is optimized to elicit broad protection against many viral antigenic variants. Since broadly protective antibodies against influenza virus often exhibit mutational evidence of prolonged diversification, we studied germinal center (GC) kinetics in hemagglutinin (HA) immunized mice. Here we report that as early as 4 day...
