Neutralizing antibodies (NAbs) are useful in identifying neutralizing epitopes of vaccine utility and for understanding the mechanism of potent and broad cross-neutralization thus providing a modality of preventive and therapeutic value. In this article we review the current understanding on the potential use of broadly neutralizing antibodies (bNAbs) in their full-length IgG structure, engineered domain antibody or bispecific versions towards preventive and therapeutic applications. The potential implications of NAbs are discussed in the light of the recent developments as key components in vaccination against HIV-1. The development of a vaccine immunogen which elicits bNAbs and confers protective immunity remains a real challenge. </p>","PeriodicalId":90371,"journal":{"name":"Therapeutic advances in vaccines","volume":"1 2","pages":"67-80"},"PeriodicalIF":0.0,"publicationDate":"2013-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2051013613494534","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32283309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, despite intensive vaccination of young children, pertussis remains a major public health problem in both developing and industrialized regions. Recent epidemics in California and Australia demonstrated that the agent of the disease is still circulating. They also revealed several aspects that must not be neglected concerning vaccine-preventable diseases. Indeed, pertussis is one of the oldest vaccine-preventable bacterial diseases, so can provide a good illustration of all of the aspects associated with the need for surveillance after the introduction of vaccination. (i) The type of vaccine: two types of pertussis vaccine, whole cell and acellular, inducing different types of immunity are now used around the world. (ii) The vaccine strategy, the vaccine coverage and the duration of vaccine immunity: pertussis epidemics provide evidence that 90% of the infants must be vaccinated, vaccination must be sufficiently early and both vaccine-induced immunity and natural infection-induced immunity to pertussis wane with time indicating that pertussis is not only a pediatric disease. (iii) The agents of the disease, Bordetella pertussis and Bordetella parapertussis: the intensive vaccination of young infants modified the herd immunity, controlled bacteria similar to the vaccine strains but not all, revealing polymorphism of the agents of the disease evidencing the importance of continuing their isolation and their surveillance as well as monitoring their antibiotic resistance. (iv) The diagnosis of the disease: the epidemics showed the importance of specific diagnostic techniques that are easy to use by medical laboratories and the availability of the reagents required. (v) Communication with the public, the health authorities and the health providers: any changes of vaccine type, vaccine strategy, characteristics of the disease, and biological diagnosis must be associated with appropriate communication with the public and training of healthcare workers. Currently, herd immunity needs to be increased by introducing vaccine boosters for adolescents and adults to protect the most vulnerable group: unvaccinated newborns.","PeriodicalId":90371,"journal":{"name":"Therapeutic advances in vaccines","volume":"1 2","pages":"59-66"},"PeriodicalIF":0.0,"publicationDate":"2013-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2051013613481348","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32282841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, despite this recommendation, vaccine coverage is generally unsatisfactory. The aim of this review is to analyze the impact of influenza on children at high risk of respiratory disease, and the immunogenicity, safety and efficacy of influenza vaccination in such children. The results show that there is a significant risk of influenza-related complications in preterm neonates and infants, in whom influenza vaccines are immunogenic and safe (although their efficacy has not been specifically studied). There are conflicting data concerning the effect of influenza infection on asthma morbidity in children, and whether or not influenza vaccination helps to prevent asthma exacerbations. Recent data provide no evidence that influenza is more frequent in patients with cystic fibrosis than in healthy subjects, or that it is responsible for increased lower respiratory tract morbidity. The lack of any clear correlate of protection suggests that future studies should also consider the efficacy of the different influenza vaccines and not only evaluate them in terms of immunogenicity. Furthermore, there is a need for clinical studies to assess the effectiveness of the available vaccines in patients with other rare CRDs and other chronic underlying diseases with possibly severe respiratory involvement. It is also important to determine whether children with recurrent respiratory tract infections should be included in the list of those for whom influenza vaccination is recommended. In the meantime, given the increasing evidence of the burden of influenza on the population as a whole and the benefits associated with vaccination, annual influenza vaccinations should be recommended for all children at high risk of respiratory disease and the members of their households. </p>","PeriodicalId":90371,"journal":{"name":"Therapeutic advances in vaccines","volume":"1 1","pages":"21-31"},"PeriodicalIF":0.0,"publicationDate":"2013-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3967668/pdf/10.1177_2051013613480770.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32282839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A major reason for this is that T cells specific for tumor self-antigens and neoantigens are eliminated or inactivated through mechanisms of tolerance. Antigen fusion strategies which increase the ability of vaccines to stimulate T cells that have escaped tolerance mechanisms, may have a particular potential as immunotherapies. This review highlights antigen fusion strategies that have been successful in stimulating the induction of T-cell immunity against cancer and counteracting tumor-associated tolerance. In preclinical studies, these strategies have shown to improve the potency of vectored vaccines through fusion of tumor antigen to proteins or protein domains that increase CD4+ T-cell help, CD8+ T-cell responses or both the CD4+ and CD8+ T-cell responses. However, in clinical trials such strategies seem to be less efficient when provided as a DNA vaccine. The first clinical trial using a viral vectored fusion-gene vaccine is expected to be tested as a partner in a heterologous prime-boost regimen directed against cervical cancer. </p>","PeriodicalId":90371,"journal":{"name":"Therapeutic advances in vaccines","volume":"1 1","pages":"33-47"},"PeriodicalIF":0.0,"publicationDate":"2013-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2051013613480446","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32282840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
