A highly sensitive online search was run using the terms 'Haemophilus Vaccines' or 'Haemophilus influenzae type b' and 'conjugate vaccine', and Medline (Ovid), PubMed, Embase, CENTRAL and Scopus were explored for prospective randomized controlled studies.

Novartis has developed a serogroup B meningococcal vaccine, 4CMenB, to meet this need. We reviewed all 4CMenB studies. The studies found 4CMenB to be highly immunogenic when administered in all schedules, with protective antibody levels (serum bactericidal antibody titres ≥4 or ≥5 with human complement, hSBA) against serogroup B strains expressing vaccine antigens in >95% of vaccinated cohorts. When antibody levels waned, all tested groups demonstrated booster responses. Although possibly an underestimation, the Meningococcal Antigen Typing System (MATS) technique predicts that global coverage of 4CMenB against all serogroup B strains is in the range 66% (Canada) to 91% (USA). The vaccine was found to be generally well tolerated, although local and systemic reactions, notably fever in infants, typical of many vaccines, were increased following concomitant administration of 4CMenB with routine vaccines. When tested, prophylactic paracetamol significantly decreased the frequency and severity of reactions in infants, with no clinically significant impact on immunogenicity of 4CMenB or concomitant routine vaccines. The vaccine is approved for use in the following age groups in the European Union (2 months+), Canada (2 months through 17 years), Australia (2 months+) and Chile (2 months+), following clinical evaluation in 4843 infants and toddlers, and 1712 adolescents and adults, in schedules including a three-dose (2, 3, 4 or 2, 4, 6 months) and a two-dose (6-11 months) infant series with a booster in the second year of life, a two-dose series in toddlers (12-23 months) and children (2-10 years) given 2 months apart (with a booster at least in the EU), and a two-dose series in adolescents (11-17 years) given 1-6 months apart. 4CMenB presents a solution to the unmet medical need of offering protection against serogroup B invasive meningococcal disease in all age groups above 2 months. </p>","PeriodicalId":90371,"journal":{"name":"Therapeutic advances in vaccines","volume":"3 1","pages":"13-23"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2051013614557477","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32945794","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 key advantage of liposomes, archaeosomes and virosomes in general, and liposome-based vaccine delivery systems in particular, is their versatility and plasticity. Liposome composition and preparation can be chosen to achieve desired features such as selection of lipid, charge, size, size distribution, entrapment and location of antigens or adjuvants. Depending on the chemical properties, water-soluble antigens (proteins, peptides, nucleic acids, carbohydrates, haptens) are entrapped within the aqueous inner space of liposomes, whereas lipophilic compounds (lipopeptides, antigens, adjuvants, linker molecules) are intercalated into the lipid bilayer and antigens or adjuvants can be attached to the liposome surface either by adsorption or stable chemical linking. Coformulations containing different types of antigens or adjuvants can be combined with the parameters mentioned to tailor liposomal vaccines for individual applications. Special emphasis is given in this review to cationic adjuvant liposome vaccine formulations. Examples of vaccines made with CAF01, an adjuvant composed of the synthetic immune-stimulating mycobacterial cordfactor glycolipid trehalose dibehenate as immunomodulator and the cationic membrane forming molecule dimethyl dioctadecylammonium are presented. Other vaccines such as cationic liposome-DNA complexes (CLDCs) and other adjuvants like muramyl dipeptide, monophosphoryl lipid A and listeriolysin O are mentioned as well. The field of liposomes and liposome-based vaccines is vast. Therefore, this review concentrates on recent and relevant studies emphasizing current reports dealing with the most studied antigens and adjuvants, and pertinent examples of vaccines. Studies on liposome-based veterinary vaccines and experimental therapeutic cancer vaccines are also summarized. </p>","PeriodicalId":90371,"journal":{"name":"Therapeutic advances in vaccines","volume":"2 6","pages":"159-82"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2051013614541440","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32788242","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}

The newer-generation oral killed cholera vaccines have been shown to be safe and effective in field trials conducted in cholera endemic areas. Likewise, they have been shown to be protective when used during outbreak settings. Aside from providing direct protection to vaccinated individuals, recent studies have demonstrated that these killed oral vaccines also confer indirect protection through herd immunity. Although new-generation oral cholera vaccines should not be considered in isolation from other preventive approaches in countries where they are most needed, especially improved water quality and sanitation, these vaccines serve as immediately available public health tools for preventing further morbidity and mortality from cholera. However, despite its availability for more than two decades, use of these vaccines has not been optimized. Although there are limitations of the currently available oral cholera vaccines, recent data show that the vaccines are safe, feasible to use even in difficult circumstances and able to provide protection in various settings.

Specifically in prostate cancer, immunotherapy has emerged as a viable and attractive treatment strategy. To date, therapeutic cancer vaccines and immune checkpoint inhibitors are the two classes of immunotherapy that have demonstrated improvements in overall survival in patients with advanced tumors. The 2010 Food and Drug Administration approval of sipuleucel-T for asymptomatic or minimally symptomatic metastatic prostate cancer set the stage for ongoing phase III trials with the cancer vaccine PSA-TRICOM and the immune checkpoint inhibitor ipilimumab. A class effect of these approved immune-based therapies is a benefit in overall survival without short-term changes in disease progression, apparently due to modulation of tumor growth rate kinetics, in which the activated immune system exerts constant immunologic pressure that slows net tumor growth. A growing body of evidence suggests that the ideal population for clinical trials of cancer vaccines as monotherapy is patients with lower tumor volume and less aggressive disease. Combination strategies include immunotherapy with standard therapies or with other immunotherapies.
