Human Vaccines

Varicela Biken [Live varicella Biken vaccine (strain Oka)] is an effective and safe vaccine for the prevention of varicella infection. Although the recommended schedule in all age groups (children, adolescents and adults) is a single dose, physicians in some countries follow the 2007 recommendation of the US Advisory Committee on Immunization Practices (ACIP) which recommends "implementation of a routine 2-dose varicella vaccination program for children, with the first dose administered at age 12--15 months and the second dose at age 4--6 years...

We are very pleased to broaden the scope and accordingly the name of our journal to Human Vaccines & Immunotherapeutics as of January. This broadening is a natural outgrowth of the evolution of technologies and approaches in our field, and acknowledges the increasing confluence and synergies between the fields of vaccines and immunotherapeutics.

During the 2009 influenza pandemic, children aged 6 months up to and including 4 years, without chronic illness, were vaccinated with two doses of Pandemrix(®) through mass vaccination in the Netherlands. During the vaccination campaign a warning was issued about fever after the second dose of Pandemrix(®). Therefore, we investigated the tolerability of both doses Pandemrix(®) in these children. Among parents of children eligible for vaccination, 1500 questionnaires were distributed during both, the first and second mass vaccination session...

Cancer vaccine targeting cancer stem cells is proposed to serve as a potent immunotherapy. Thus, it would be useful to examine the main trends in stem cell patenting activity as a guide for those seeking to develop such cancer vaccines. We found that a substantial number of stem cell patents were granted up to the end of 2010, including ~2000 issued in the US. Many of these have been filed since 2001, including 7,551 applications in the US. Stem cell development, as evidenced by the numbers of PubMed articles, has matured steadily in recent years...

The approval of Provenge (Dendreon) in 2010 signaled the dawn of a new era in the development of active immunotherapeutics. For cancer treatment, the approval of Provenge® demonstrates that the immune system can effectively be harnessed to combat cancer. The outlook for active immunotherapies looks bright in terms of promising new approaches and candidates, as well as novel adjuvants and treatment regimens for therapy development.

The thirteen valent pneumococcal conjugate vaccine (PCV13, Prevenar 13(TM)) is the broader coverage successor to the highly effective seven valent vaccine (PCV7, Prevenar(TM)) which has reduced rates of pneumococcal disease in many countries. Despite the success of PCV7, pneumococcal disease due to non-PCV7 serotypes remains a threat in many settings, in particular many developing countries with a high burden of pneumococcal disease where serotype 1 and 5 are among the most common serotypes. Disease due to certain non-PCV7 serotypes, in particular serotype 19A has also begun to increase in incidence in countries with widespread use of PCV7...

Vaccines are a cornerstone in any pandemic influenza preparedness plan. Successful supplementary mass vaccination programs require proper advance planning. We aimed to identify general, and Israeli specific, challenges and opportunities before initiating the Israeli pandemic influenza vaccination program in order to better plan implementation of the program. Following the vaccination campaign the analysis was retrospectively examined in order to determine whether the challenges were properly identified and whether the opportunities were indeed realized...

Malaria is a leading cause of morbidity and mortality in Kenya. To confront malaria, the Government of Kenya has been implementing and coordinating three approaches - vector control by distributing insecticide-treated bed nets and indoor residual spraying, case management, and the management of malaria during pregnancy. Immunization is recognized as one of the most cost-effective public health interventions. Efforts are underway to develop a malaria vaccine. The most advanced (RTS,S), is currently going through phase 3 trials...

We analyzed seasonal flu vaccination rates among the Italian population suffering from Chronic Obstructive Pulmonary Disease (COPD) in order to identify socio-demographic and clinical determinants for vaccination. We used data from the survey "Health and health care use in Italy", which interviewed 5,935 persons (age 15 - 102 years) suffering from COPD in the period 2004-2005. For each respondent, information on socioeconomic and health conditions, smoking status and patterns of health care utilization were retrieved...

In the present study, we explored and compared the binding activity and immunogenic characterization of the most effective part corresponding to C-terminal quarter of heavy chain of botulinum neurotoxin serotype A (AHc-C) with C-terminal half of heavy chain of botulinum neurotoxin serotype A (AHc). Firstly, the fully soluble AHc-C protein successfully expressed in Escherichia coli by co-expression with thioredoxin (Trx) was shown to bind with ganglioside as the AHc, indicating that the recombinant AHc-C protein retains a functionally active conformation...

AIMS: In this study, the immune-modulatory and protective efficacy of using an interleukin-2 (IL-2) expression plasmid as a genetic adjuvant and chitosan (CS) nanoparticles as vectors to enhance a Tp92 DNA vaccine candidate were investigated in a Treponema pallidum (Tp) rabbit challenge model. RESULTS: CS vectoring of pTp92 or pIL-2 were both demonstrated to augment anti-Tp92 antibody levels induced by pTp92 DNA vaccines. Interestingly, the combination of CS vectored Tp92 and pIL-2 led to the greatest enhancements of anti-Tp92 antibodies and T-cell proliferation (p < 0...

BACKGROUND: Age is a major risk factor for herpes zoster (HZ) and its potential long-term complication post-herpetic neuralgia (PHN). Due to the significant burden of HZ and PHN on patients' quality of life, it is vital that effective and well-tolerated vaccines are available to prevent HZ in older adults. ZOSTAVAX(®) vaccine was developed to prevent HZ and PHN in individuals ≥50 years (y) of age, and its clinical efficacy and safety have been demonstrated. AIMS AND METHODS: This phase 4, open-label, multicenter study was undertaken to assess the immunogenicity and safety of a single dose of ZOSTAVAX (refrigerator-stable formulation) given within 6 mo of its expiry date in individuals ≥50 y of age...

Infections with Pseudomonas aeruginosa are a major health problem for immune-compromised patients and individuals with cystic fibrosis. A vaccine against: P. aeruginosa has long been sought after, but is so far not available. Several vaccine candidates have been assessed in experimental animals and humans, which include sub-cellular fractions, capsule components, purified and recombinant proteins. Unique characteristics of the host and the pathogen have complicated the vaccine development. This review summarizes the current state of vaccine development for this ubiquitous pathogen, in particular to provide mucosal immunity against infections of the respiratory tract in susceptible individuals with cystic fibrosis...

A post-marketing, double blind, randomised, controlled clinical trial to assess the immunogenicity and safety profiles of four commercially available recombinant hepatitis B vaccines was performed. The vaccines included in this study were Heberbiovac-HB (®) (Heber Biotec S.A., Havana, Cuba), Euvax-B (®) (LG Chemical Ltd., Seoul, Korea), Hepavax-Gene (®)   (Greencross Vaccine Corp., Seoul, Korea), and Engerix-B (®) (GlaxoSmithKline Biologicals, Rixensart, Belgium). Vaccines were administered intramuscularly to healthy adults in three 20mg doses at monthly intervals (0 - 1 -  2 months)...

Vaccination of adults aged 60 years and older against Streptococcus pneumonia is not recommended in Brazil. The 23-valent polysaccharide pneumococcal vaccine (PPV23) is only available for institutionalized persons or with underlying diseases despite the substantial medical and economic burden related to pneumococcal infections in adults over than 59 years. The study aimed at evaluating the cost effectiveness of implementing a large PPV program in this population. This analysis was performed using a static decision tree model...

We characterized parental attitudes regarding school HPV vaccination requirements for adolescent girls. Study participants were 866 parents of 10–18 y-old girls in areas of North Carolina with elevated cervical cancer incidence. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) by logistic regression. Approximately half (47%) of parents agreed that laws requiring HPV immunization for school attendance "are a good idea" when opt-out provisions were not mentioned. Far more agreed that "these laws are okay only if parents can opt out if they want to" (84%)...

AIM: Because of the high mother-to-infant transmissibility of hepatitis B (HB) infection, neonatal vaccination is necessary, but the further doses of HB vaccines can be combined with conventional diphtheria-tetanus-whole cell pertussis (DTPw) vaccines. We compared immunogenicity and reactogenicity of two tetravalent vaccines in Indian children, who after neonatal HB immunization, were vaccinated thrice with one of these vaccines. METHODS: In this open-label randomized study, 287 infants received a dose of an Indian- (Q-Vac (TM )) or European-made (Tritanrix-HB (TM )) tetravalent vaccine at age 6, 10, and 14 weeks...
