Abstract
Introduction: Combination vaccines reduce the number of injections received by children, hence improving timeliness and coverage, and general acceptability among caregivers and health-care providers. The most recent hexavalent vaccine, DTaP5-HBV-IPV-Hib, has been also approved by the FDA.Areas covered: DTaP5-HBV-IPV-Hib has demonstrated good immunogenic and safety profiles, not inferior to other hexavalent vaccines already in use in the European market. Either (2p+1/3p+1) immunization schedules can be used with no significant differences. A low incidence of severe adverse events has been shown, similar to other combination vaccines. No issues have arisen when concomitantly administered with other vaccines.Expert opinion: The inclusion of two additional acellular pertussis components (FIM2 and FIM3) might yield better protection against the disease, but this remains to be clinically proven. The new vaccine uses Hib with unique protein carrier (PRP-OMPC) which elicits higher earlier immune response without compromising safety. Compliance with the immunization schedules is expected to increase by decreasing the number of injections needed in combined vaccines for a single visit. In addition, the improvements on the ease-of-use by its liquid-formulation, makes the vaccine preparation more acceptable for use in clinics and may reduce the odds of administration errors.

Abstract
DTaP5-IPV-HB-Hib vaccine is a fully-liquid, combination hexavalent vaccine. This phase III, open-label, multicentre study conducted in Spain, evaluated the immune response to all DTaP5-IPV-HB-Hib antigens when the vaccine was used in a mixed hexa/penta/hexa primary series. Infants (who had received one dose of hepatitis B vaccine at birth) received a mixed schedule including DTaP5-IPV-HB-Hib (PRP-OMP conjugate) at 2 and 6months of age, DTaP5-IPV-Hib at 4months, meningococcal serogroup C conjugate (MCC) vaccine at 2 and 4months, and routine rotavirus and pneumococcal vaccination. One month post-dose 3 of the mixed schedule, response rates were considered acceptable if the lower bound of the two-sided 95% confidence interval around the post-vaccination response rate was >90% for hepatitis B and >80% for Haemophilus influenzae type b (Hib). Secondary immunogenicity objectives included description of the antibody response to all hexavalent antigens one month after completion of the mixed schedule, and to MCC antigen one month after the second MCC dose. The safety profile after each dose of study vaccine was described. Of 385 healthy infants enrolled, 384 completed the study. The primary objective was achieved for both hepatitis B and Hib; the lower bound of the 2-sided 95% CI of the response rates (97.2% and 99.0%, respectively) were greater than the pre-specified acceptability thresholds. One month post-dose 3 of the mixed schedule, all participants were seroprotected against diphtheria, tetanus and polio. The mixed schedule induced a robust immune response to all hexavalent antigens. The co-administration of the hexavalent vaccine in a mixed schedule with MCC vaccine did not reduce the immune response to vaccine antigens. Vaccines were well tolerated. In conclusion, the acceptability of response rates against Hib and hepatitis B were demonstrated one month post-dose 3 of the mixed schedule; robust immune responses against all other hexavalent antigens were observed. clinicaltrial.gov: NCT01839188; EudraCT: 2012-004221-25.

Abstract
UNLABELLED In 2011, the 7-valent conjugated pneumococcal vaccine (PCV7) was replaced by the 10-valent vaccine (PCV10) and universal hepatitis B vaccination has been introduced in the Netherlands. A questionnaire study was conducted to assess the tolerability of DTaP-IPV-Hib + PCV7 (PCV7-cohort), DTaP-IPV-Hib + PCV10 (PCV10-cohort), and DTaP-IPV-Hib-HepB + PCV10 (HepB-cohort). Parents were asked to report in questionnaires local reactions and systemic adverse events (AEs) before and after vaccination of their infant at 2, 3, 4, and 11 months of age. For 29.0 and 29.4% infants of the PCV7-cohort, at least one local reaction was reported in the week after the first dose of DTaP-IPV (left leg) and PCV-7 vaccination (right leg). Significantly more infants from the PCV10-cohort (45.1%, p < 0.001 and 44.6%, p < 0.001) and HepB-cohort (42.6%, p < 0.001 and 41.9%, p < 0.001) reported at least one local reaction. This effect was less pronounced after the successive doses. Most of the infants experienced at least one systemic AE, and after dose 4, this was higher for infants in the PCV10-cohort (65.9%, p = 0.047) and HepB-cohort (70.6%, p = 0.000) compared to the PCV7-cohort (62.3%). CONCLUSION Addition of antigens to a vaccine resulted in a higher reactogenicity, but the AEs were in general mild and transient. What is Known: • Assessment of adverse events is crucial for achieving the highest safety in immunization programs, in order to inform public health actions and maintain public confidence in immunization programs. What is New: • Newly introduced vaccines DTaP-IPV-Hib-HepB and PCV10 are generally safe and well tolerated in infants. • These results are useful for information purposes and for monitoring variations in rates of AEs in the general population or in the target group over time.

Abstract
BACKGROUND The objective of this retrospective study was to assess protection against vaccine preventable diseases (VPDs) in children treated for acute lymphoblastic leukemia (ALL). PROCEDURE Clinical characteristics and vaccination records were collected. Antibodies against VPDs were measured after completion of chemotherapy and after a booster dose of vaccine. Immunization status of household members was evaluated. RESULTS Sixty children were included. Median interval between the end of chemotherapy and enrolment in the study was 13 months (range 1-145). At ALL diagnosis, 81.3% of the children were up to date with their vaccination schedule. This proportion decreased to 52.9% at enrolment. Among the parents, 21% were up to date with their immunization schedule and 42% had received seasonal influenza vaccination. After chemotherapy, less than 50% of the patients were seroprotected against tetanus, diphtheria, polio 3, Haemophilus influenzae type b (Hib), and mumps and no more than 80% were seroprotected against polio 1 and 2, measles, rubella, and varicella. After a booster dose of vaccine, the rate of protection increased to over 90% for each of the following antigens: TT, DT, polio 1, Hib, measles, and rubella. Nevertheless, polio 3, mumps, and varicella-zoster virus antibodies titers/concentrations remained below seroprotective thresholds in over 20% of the patients. CONCLUSIONS After chemotherapy for ALL, most of the children were not protected against VPDs. As the majority mounted a robust response to booster vaccines, efforts need to be done to improve protection against VPDs by implementing a systematic vaccine booster schedule. This could also be helped by reinforcing household members' immunization.

Abstract
Vaxelis® is a fully liquid, ready-to-use, hexavalent vaccine approved in the EU for primary and booster vaccination in infants and toddlers from the age of 6 weeks against diphtheria, tetanus, pertussis, hepatitis B, poliomyelitis, and invasive diseases caused by Haemophilus influenzae type b (Hib). It contains diphtheria and tetanus toxoids, five acellular pertussis antigens, recombinant hepatitis B virus surface antigen produced in the yeast, Saccharomyces cerevisiae, inactivated poliovirus, and the Hib polysaccharide (polyribosylribitol phosphate) conjugated to the outer membrane protein complex of Neisseria meningitidis. In pivotal clinical studies, Vaxelis® was highly immunogenic for all its component toxoids/antigens when administered by three different schedules. Primary endpoints of seroprotection or vaccine response rates with Vaxelis® met the predefined acceptability criteria and were noninferior to those with comparator vaccines (Infanrix® hexa or Pentacel® plus Recombivax HB®). Limited data indicate that immune responses to Vaxelis® in preterm infants were generally similar to those seen in the overall population. Vaxelis® can be coadministered with a number of common childhood vaccines. In clinical studies, Vaxelis® was generally well tolerated with a tolerability profile similar to that of the comparator vaccines. Available clinical data indicate that Vaxelis® is a new hexavalent vaccine option for immunization against several serious childhood infectious diseases.

Abstract
INTRODUCTION Combination vaccines reduce the 'shot burden' and simplify the childhood immunization schedule. Only 5-valent DTaP-based vaccines are licensed in the U.S. Areas covered: A new combination vaccine - DTaP5-IPV-Hib-HepB - is described, which induces antibody responses in infants (given in different schedules, including a 2, 4, and 6-month schedule) that are similar to the respective component vaccines. The vaccine appears to be safe and would be expected to protect against six diseases: diphtheria, tetanus, pertussis, hepatitis B, H influenzae type b, and polio. Administration is associated with higher rates of mild fever, but without significant safety signals. Expert commentary: Incorporation of this hexavalent vaccine into the U.S. schedule could improve coverage rates and timeliness, and addition to the E.U. market would add depth to the available repertoire of combination vaccines.

Abstract
BACKGROUND Combination diphtheria-tetanus-5 component acellular pertussis-inactivated poliovirus-Haemophilus influenzae b conjugate-hepatitis B vaccine (DTaP5-IPV-Hib-HepB) administered either concurrently with 7-valent pneumococcal conjugate vaccine (PCV7) or 1 month apart was generally safe and immunogenic at 2, 4 and 6 months of age. This study examined the effects of a booster dose at age 15 months. METHODS Participants were randomized to DTaP5-IPV-Hib-HepB plus PCV7, DTaP5-IPV-Hib-HepB with PCV7 administered 1 month later or a pentavalent DTaP5-IPV/Hib plus HepB plus PCV7 at 15 months of age in a randomized, open-label, phase IIb clinical trial. Immunogenicity endpoints were rates of seroresponse to pertussis toxoid, filamentous hemagglutinin, pertactin and fimbriae types 2 and 3; rates of seroprotection against (Hib) polyribosylribitol phosphate capsular polysaccharide, hepatitis B surface antigen, diphtheria toxoid, tetanus toxoid and poliovirus types 1, 2 and 3; and geometric mean titers to all vaccine antigens. Safety endpoints included solicited injection-site reactions and systemic and serious adverse events. RESULTS Seroresponse/seroprotection rates for all antigens exceeded prespecified criteria in both groups that received the hexavalent DTaP5-IPV-Hib-HepB; in the group that received the currently licensed pentavalent vaccine, seroresponse/seroprotection rates exceeded the criteria for all antigens except filamentous hemagglutinin. Seroresponse rates were ≥88.9% for pertussis antigens and seroprotection rates against polyribosylribitol phosphate capsular polysaccharide, hepatitis B surface antigen, diphtheria toxoid, tetanus toxoid and poliovirus antigens were ≥95.1% in recipients of DTaP5-IPV-Hib-HepB. CONCLUSIONS DTaP5-IPV-Hib-HepB administered concomitantly with PCV7 or 1 month apart at 15 months of age following the infant series was well-tolerated and elicited antibody responses to all vaccine antigens, with no significant interference from concomitant PCV7 administration (clinicaltrials.gov registration number NCT00362427).

Abstract
BACKGROUND DTaP₅-IPV-Hib-HepB, an investigational hexavalent combination vaccine, was evaluated for safety and immunogenicity, when administered to infants with heptavalent pneumococcal conjugate vaccine (PCV7). METHODS Infants were randomized to receive DTaP₅-IPV-Hib-HepB plus PCV7, DTaP₅-IPV-Hib-HepB with PCV7 administered 1 month later or DTaP₅-IPV/Hib plus HepB plus PCV7 at 2, 4 and 6 months of age in an open-label, phase IIb trial. Vaccine responses were assessed by pertussis toxoid, filamentous hemagglutinin, pertactin and fimbriae types 2/3 seroconversion rates, Haemophilus influenzae type b polyribosylribitol phosphate capsular polysaccharide, hepatitis B surface antigen, diphtheria toxoid, tetanus toxoid and poliovirus types 1, 2 and 3 seroprotection rates and geometric mean titers. Solicited injection site and systemic reactions, serious adverse events, and other safety outcomes were reported. RESULTS Seroprotection rates to polyribosylribitol phosphate, hepatitis B surface antigen, diphtheria toxoid, tetanus toxoid and poliovirus antigens across all groups met or exceeded predetermined acceptability criteria. Seroconversion rates to pertussis toxoid, pertactin and fimbriae types 2/3, but not filamentous hemagglutinin, met such criteria. Antidiphtheria antibodies were significantly lower when PCV7 was coadministered. Geometric mean titers to the other antigens of the hexavalent and PCV7 vaccines were all high and similar in the 2 groups. No safety signals were noted. CONCLUSIONS DTaP₅-IPV-Hib-HepB administered at 2, 4 and 6 months of age concomitantly with PCV7 was well tolerated and elicited robust antibody responses to all but the antidiphtheria antigens for which there may be evidence of immune interference. Only filamentous hemagglutinin did not meet seroconversion rate acceptability criteria.

Abstract
BACKGROUND Advantages to combining childhood vaccines include reducing the number of visits, injections and patient discomfort, increasing compliance and optimising prevention. The World Health Organization (WHO) recommends that routine infant immunisation programmes include a vaccination against Haemophilus influenzae (H. influenzae) type B (HIB) in the combined diphtheria-tetanus-pertussis (DTP)-hepatitis B virus (HBV) vaccination. The effectiveness and safety of the combined vaccine should be carefully and systematically assessed to ensure its acceptability by the community. OBJECTIVES To compare the effectiveness of combined DTP-HBV-HIB vaccines versus combined DTP-HBV and separate HIB vaccinations. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 4), which contains the Cochrane Acute Respiratory Infections Group's Specialised Register, MEDLINE (January 1966 to week 1, November 2011), EMBASE (January 1990 to November 2011) and www.clinicaltrials.gov (up to April 2011). SELECTION CRITERIA Randomised controlled trials (RCTs) or quasi-RCTs comparing vaccination with any combined DTP-HBV-HIB vaccine, with or without three types of inactivated polio virus (IPV) or concomitant oral polio vaccine (OPV) in any dose, preparation or time schedule, compared with separate vaccines or placebo, administered to infants up to two years old. DATA COLLECTION AND ANALYSIS Two review authors independently inspected references identified by the searches and evaluated them against the inclusion criteria, extracted data and assessed the methodological quality of included trials. MAIN RESULTS Data for the primary outcome (prevention of disease) were lacking. We performed a meta-analysis to pool the results of 20 studies with 5874 participants in an immunogenicity analysis and 5232 participants in the reactogenicity analysis. There were no data on clinical outcomes for the primary outcome (prevention of disease) and all studies used immunogenicity and reactogenicity (adverse events). The number of vaccine doses differed significantly between the studies. Heterogeneous interventions, study location, healthcare environment and combining research across disparate geographical locations, may have lead to bias. The risk of bias was unclear across most of the included studies. Comparisons found little heterogeneity. In two immunological responses the combined vaccine achieved lower responses than the separate vaccines for HIB and tetanus. No significant differences in immunogenicity were found for pertussis, diphtheria, polio and hepatitis B. Serious adverse events were comparable with mainly hospitalisation and acute bronchiolitis cases. Minor adverse events such as pain and redness were more common in children given the combined vaccine. Overall, the direction shown by the results is in favour of the DTPw (diptheria-tetanus-whole cell pertussis)-HBV-HIB vaccine rather than the DTPa (diptheria-tetanus-acellular pertussis)-HBV-HIB vaccine when compared to the separate vaccines (size of effect: risk ratio (RR) 1.43; 95% confidence interval (CI) 0.98 to 2.10, for 5269 participants). AUTHORS' CONCLUSIONS We could not conclude that the immune responses elicited by the combined vaccine were different from or equivalent to the separate vaccines. There was significantly less immunological response for HIB and tetanus and more local reactions in the combined injections. However, these differences rely mostly on one study each. Studies did not use an intention-to-treat (ITT) analysis and we were uncertain about the risk of bias in many of the studies. These results are therefore inconclusive. Studies addressing clinical end points whenever possible, using correct methodology and a large enough sample size should be conducted.

Abstract
Diphtheria, tetanus and pertussis vaccines have formed the cornerstone of childhood immunization programs for decades. Historically, these have comprised diphtheria and tetanus toxoids combined with inactivated whole-cell pertussis. More recently, advances have been made with the development of purified acellular pertussis vaccines, with improved reactogenicity profiles, and formulation with additional vaccines such as Haemophilus influenzae type b, hepatitis B virus and inactivated poliovirus. Development is currently focused on maximizing the number of vaccines that can be combined in a single formulation and strategies to provide protection against pertussis before the commencement of routine infant immunization.

Abstract
BACKGROUND AND AIMS Assessment of a new, fully liquid, investigational hexavalent DTaP-IPV-Hep B-PRP-T vaccine (Hexaxim, Sanofi Pasteur), containing the same active ingredients as Pentaxim (DTaP-IPV//PRT-T) and 10 μg Hansenula polymorpha-derived recombinant hepatitis B (Hep B) surface antigen, Sanofi Pasteur, in Argentinean infants. METHODS Infants born to Hep B surface antigen seronegative mothers were randomized to receive the DTaP-IPV-Hep B-PRP-T vaccine or Pentaxim and Engerix B Pediatrico (Hep B monovalent) vaccines at 2, 4, 6 months of age. Antibody titers were measured before and 1 month after 3-month primary vaccination. Noninferiority analyses were performed on seroprotection/seroconversion rates. Safety was evaluated descriptively up to 1 month after primary vaccination. RESULTS A total of 624 participants were enrolled, 312 participants were randomized to each group, and 604 participants completed the trial. The DTaP-IPV-Hep B-PRP-T vaccine was demonstrated as noninferior to the Pentaxim and Hep B monovalent vaccines with seroprotection/seroconversion rates 1 month postdose 3 for each valence. The anti-Hep B geometric mean titer 1-month postdose 3 for the investigational DTaP-IPV-Hep B-PRP-T primary series was similar to the monovalent Hep B control. The overall incidence of adverse events was similar among the 2 groups. CONCLUSIONS The new, fully liquid, investigational DTaP-IPV-Hep B-PRP-T vaccine (Hexaxim) is highly immunogenic and safe when compared with licensed comparators, warranting further development.
