Safety and Immunogenicity of a Quadrivalent Meningococcal Polysaccharide Diphtheria Toxoid Conjugate Vaccine in Infants and Toddlers

Quadrivalent meningococcal conjugate vaccine (Menactra [MenACWY-D]), was licensed in the United States in 2005 to prevent meningococcal disease in adolescents and adults. The license was extended to children aged 2-10 years in 2007 and extended again in 2011 to infants aged 9 months and older based, in part, on results from 3 phase III studies presented herein. The safety and immunogenicity of 2 doses of MenACWY-D was assessed in study-eligible children: dose 1 was administered at 9 months of age and dose 2 was administered 3 months later with or without routine childhood vaccines. Thirty days after vaccination, protective serum bactericidal assay-human complement titers ≥1:8 for meningococcal serogroups A, C, Y and W-135 were achieved by 86-100% of children receiving 2 doses of MenACWY-D. When MenACWY-D was concomitantly administered with measles, mumps, rubella and varicella or heptavalent pneumococcal conjugate vaccine, 81-98% of participants achieved protective responses (serum bactericidal assay-human complement titers ≥1:8 for all serogroups). All seroprotection rates were >91% when the protective titer was defined as serum bactericidal assay-human complement ≥1:4. MenACWY-D did not interfere with measles, mumps, rubella or varicella vaccine responses (98-100% achieved protective titers). When heptavalent pneumococcal conjugate vaccine was given concomitantly with MenACWY-D, antipneumococcal antibody levels, although decreased, were protective for all serotypes by enzyme-linked immunosorbent assay (98-100% ≥ 0.35 μg/mL) and opsonophagocytic assay (99-100% ≥ 1:8). Adverse events were generally mild and similar across groups. Serious adverse events were uncommon. MenACWY-D was safe and immunogenic when given in 2 doses to infants and toddlers; this vaccine can be given with other common childhood immunizations.

Evolving epidemiology of invasive Haemophilus infections in the post-vaccination era: results from a long-term population-based study

Historically, Haemophilus influenzae (Hi) serotype b (Hib) caused most invasive Haemophilus infections worldwide, mainly in children. In 1989 routine childhood vaccination against Hib was initiated in Iceland. We conducted a population-based study of all patients in the country with Haemophilus spp. isolated from sterile sites (n = 202), from 1983 to 2008. Epidemiology, clinical characteristics of the infections and serotypes of the isolates were compared during the pre-vaccination (1983–1989) and post-vaccination era (1990–2008). Following the vaccination, the overall incidence of Hib decreased from 6.4 to 0.3/100 000 per year (p <0.05) whereas the incidence did not change significantly for infections caused by Haemophilus sensu lato not serotype b, hereafter referred to as non-type b Hi (0.9 vs 1.2, respectively). The most frequent diagnosis prior to 1990 was meningitis caused by Hib, which was subsequently replaced by pneumonia and bacteraemia caused by non-type b Hi. Most commonly, non-type b Hi were non-typeable (NTHi; 40/59), followed by Hi serotype f (14/59) and Hi serotype a (3/59). Pregnancy was associated with a markedly increased susceptibility to invasive Haemophilus infections (RR 25.7; 95% CI 8.0–95.9, p <0.0001) compared with non-pregnant women. The case fatality rate for Hib was 2.4% but 14% for non-type b Hi, highest at the extremes of age. Hib vaccination gives young children excellent protection and decreases incidence in the elderly due to herd effect in the community. Replacement with other species or serotypes has not been noted. Pregnant women are an overlooked risk group.

Varicella vaccines.

Varicella zoster virus infection (VZV) is widespread and clinically important as the cause of varicella pneumonitis and meningoencephalitis (a complication of primary infection/zoster) and post-herpetic neuralgia (a complication of zoster/secondary infection). The use of live-attenuated varicella vaccine to reduce the burden of these diseases has been established in many countries for a number of years. Original papers and review articles including guidelines and recommendations by the American Academy of Paediatrics Committee on Infectious Diseases, the Advisory Committee on Immunization Practices and EuroSurveillance. Immunoassay of VZV IgG by enzyme immunosorbent assay is used as a surrogate marker for previous primary infection or successful immunization. Patients who have had natural primary infection do not require vaccination against varicella. Live VZV vaccines are safe and effective at protecting against disease caused by VZV. To ensure long-term protection, a two-dose immunization regime is strongly recommended, due to significant waning of protection following a single dose. Universal two-dose immunization has been shown to be cost-effective in Western temperate countries. In many countries, routine vaccination of children is recommended but, due to cost, often not provided by universal programmes. Cost-effectiveness of a universal programme will be determined by the baseline rate of severe varicella disease. No international consensus exists: measurement of VZV immunity or cost-effectiveness of introducing VZV vaccination to a country. Decisive factors will include the pre-vaccination burden of VZV-associated disease.

A fully liquid DTaP-IPV-Hep B-PRP-T hexavalent vaccine for primary and booster vaccination of healthy Mexican children

ObjectivesTo evaluate an investigational, fully liquid hexavalent diphtheria-tetanus-acellular pertussis-inactivated poliovirus-hepatitis B-Haemophilus influenzae type b (DTaP-IPV-Hep B-PRP-T: Hexaxim™) vaccine for primary and booster vaccination of healthy children in Mexico. MethodsInfants (N=1189) were randomized to receive one of three lots of the DTaP-IPV-Hep B-PRP-T vaccine or a licensed hexavalent control vaccine (Infanrix™ hexa) for primary vaccination at 2, 4 and 6 months. All participants who completed the primary series and agreed to participate in the booster part of the study received a dose of the investigational vaccine at 15–18 months of age. Validated serological assays and parental reports were used to assess immunogenicity and safety, respectively. ResultsPost-primary vaccination, ≥95.8% of participants in both the DTaP-IPV-Hep B-PRP-T and control groups were seroprotected (SP) against diphtheria, tetanus, poliovirus, hepatitis B and PRP, or had seroconverted (SC) to the pertussis toxin (PT) and filamentous hemagglutinin (FHA) pertussis antigens. The SP/SC rates induced by the three DTaP-IPV-Hep B-PRP-T lots were equivalent. No differences in SP/SC rates were observed between the pooled lots of investigational vaccine and the control vaccine. Antibody persistence at 15–18 months was comparable between groups, with strong increases in all antibody concentrations post-DTaP-IPV-Hep B-PRP-T booster. Both vaccines were well tolerated for primary vaccination, as was the booster dose of DTaP-IPV-Hep B-PRP-T. ConclusionThese study findings confirm the suitability of the combined, fully liquid DTaP-IPV-Hep B-PRP-T vaccine for inclusion in routine childhood vaccination schedules.

The perceptions on male circumcision as a preventive measure against HIV infection and considerations in scaling up of the services: a qualitative study among police officers in Dar es Salaam, Tanzania

BackgroundIn recent randomized controlled trials, male circumcision has been proven to complement the available biomedical interventions in decreasing HIV transmission from infected women to uninfected men. Consequently, Tanzania is striving to scale-up safe medical male circumcision to reduce HIV transmission. However, there is a need to investigate the perceptions of male circumcision in Tanzania using specific populations. The purpose of the present study was to assess the perceptions of male circumcision in a cohort of police officers that also served as a source of volunteers for a phase I/II HIV vaccine (HIVIS-03) trial in Dar es Salaam, Tanzania.MethodsIn-depth interviews with 24 men and 10 women were conducted. Content analysis informed by the socio-ecological model was used to analyze the data.ResultsInformants perceived male circumcision as a health-promoting practice that may prevent HIV transmission and other sexually transmitted infections. They reported male circumcision promotes sexual pleasure, confidence and hygiene or sexual cleanliness. They added that it is a religious ritual and a cultural practice that enhances the recognition of manhood in the community. However, informants were concerned about the cost involved in male circumcision and cleanliness of instruments used in medical and traditional male circumcision. They also expressed confusion about the shame of undergoing circumcision at an advanced age and pain that could emanate after circumcision. The participants advocated for health policies that promote medical male circumcision at childhood, specifically along with the vaccination program.ConclusionsThe perceived benefit of male circumcision as a preventive strategy to HIV and other sexually transmitted infections is important. However, there is a need to ensure that male circumcision is conducted under hygienic conditions. Integrating male circumcision service in the routine childhood vaccination program may increase its coverage at early childhood. The findings from this investigation provide contextual understanding that may assist in scaling-up male circumcision in Tanzania.

Acceptance of and attitudes towards human papillomavirus vaccination in Japanese mothers of adolescent girls

To better understand how to achieve high uptake rates of human papillomavirus (HPV) vaccination in Japan, we investigated acceptance of and attitudes towards HPV vaccination in 2192 mothers of girls aged 11–14yrs. A school-based survey was conducted in five elementary and fourteen junior high schools in Sapporo, Japan. Responses from 862 participants were analyzed. Ninety-three percent of mothers would accept the vaccine for their daughter if free, but only 1.5% was willing to pay the minimum recommended price of ¥40,000. Vaccine acceptance was higher in mothers who had heard of HPV vaccine (adjusted odds ratio, aOR=2.58, confidence interval, CI=1.47–4.53), and who believed susceptibility to (aOR=2.30, CI=1.34–3.92) and severity of (aOR=3.73, CI=1.41–9.88) HPV to be high. Recommendations from a doctor (aOR=12.60, CI=7.06–21.48) and local health board (aOR=27.80, CI=13.88–55.86) were also positively associated with increased HPV vaccine acceptance. Concerns about side effects of both the HPV vaccine (aOR=0.03, CI=0.01–0.08) and routine childhood vaccines in general (aOR=0.11, CI=0.02–0.78) emerged as barriers to vaccination. Not participating in routine cervical screening also emerged as a deterrent (aOR=0.49, CI=0.27–0.91). While most mothers (66.8%) agreed that 10–14yr was an appropriate age for vaccination, a further 30.6% believed >15yr to be more appropriate.In conclusion, attitudes of Japanese mothers toward HPV vaccination are encouraging. While lower vaccine acceptance in mothers who do not undergo regular cervical screening needs further investigation, this study indicates that high uptake may be possible in a publically funded HPV vaccination program if physicians actively address safety concerns and justify why the vaccine is needed at a particular age.

Immunogenicity and safety of 10-valent pneumococcal non-typeable Haemophilus influenzae protein D-conjugate vaccine (PHiD-CV) co-administered with routine childhood vaccines in Taiwan

The immunogenicity and safety of the 10-valent pneumococcal nontypeable Haemophilus influenzae (H. Influenzae) protein D conjugate vaccine (PHiD-CV), co-administered with routine childhood vaccines, were assessed in Taiwanese infants. In this open study, 230 healthy infants were primed with three doses of PHiD-CV (Synflorix) and diphtheria, tetanus, acellular pertussis, hepatitis B (HBV), inactivated poliomyelitis and Haemophilus influenzae type b (Hib) conjugate vaccine (DTPa-HBV-IPV/Hib vaccine) at 1.5, 3 and 6 months of age and two doses of oral human rotavirus vaccine at 1.5 and 3 months. Pneumococcal immune responses were assessed 1 month post-dose three, by 22F-inhibition ELISA and opsonophagocytic activity (OPA) assay. Local and general solicited/unsolicited symptoms and serious adverse events (SAEs) were recorded. At least 95.4% of participants had an antibody concentration ≥ 0.2 μg/mL against each vaccine serotype. At least 96.1% of participants had an OPA titer ≥ 8 against each vaccine serotype except 6B (87.3%). All infants, but one, were seropositive for antibodies against nontypeable H. influenzae protein D. Immune responses to the co-administered vaccines were good and in line with previous reports. PHiD-CV was well tolerated, with low (≤ 6.3%) incidences of grade 3 solicited local symptoms. The frequencies of general symptoms were in line with other pneumococcal conjugate vaccine studies. There were no systematic increases in incidences of solicited general or local symptoms with successive doses. There were no reports of grade 3 fever (rectal temperature > 40 °C) or SAEs considered to be causally related to vaccination. PHiD-CV co-administered with routine childhood vaccines within the first 6 months of life, was highly immunogenic, and well tolerated in Taiwanese infants.

Inequity in childhood immunization in India: A systematic review

Despite a reduction in disease burden of vaccine preventable diseases through childhood immunization, considerable progress needs to be made in terms of ensuring efficiency and equity of vaccination coverage. To conduct a systematic review to identify and explore factors associated with inequities in routine vaccination of children in India. Publications reporting vaccination inequity were retrieved through a systematic search of Medline and websites of the WHO, UNICEF and demographic health surveys in India. No restrictions were applied in terms of study designs. The primary outcome measure was complete vaccination or immunization defined as per the standard WHO definition. There were three nationwide data sets viz. the three National Family Health Surveys (NFHS), a research study conducted by the Indian Council of Medical Research (ICMR) and a UNICEF coverage evaluation survey. In addition, several publications representing different population groups or geographic regions were available. A small number of publications were reanalyses of data from the NFHS series. There is considerable inequity in vaccination coverage in different states. Within states, traditionally poor performing states have greater inequities, although there are significant inequities even within better performing states. There are significant inequities in childhood vaccination based on various factors related to individual (gender, birth order), family (area of residence, wealth, parental education), demography (religion, caste), and the society (access to health-care, community literacy level) characteristics. Girls fare uniformly worse than boys and higher birth order infants have lower vaccination coverage. Urban infants have higher coverage than rural infants and those living in urban slums. There is an almost direct relationship between household wealth and vaccination rates. The vaccination rates are lower among infants with mothers having no or low literacy, and families with insufficient empowerment of women. Paternal literacy has an inconsistent positive relationship with infant vaccination. There is a relationship between religion and caste and childhood vaccination. Access to health services and other infrastructure, is associated with better vaccination coverage of infants. The precise impact of specific risk factors operating singly or in combination cannot be calculated from this systematic review. This systematic review identifies and explores factors associated with inequity in childhood immunization in India; and provides information for urgent action to redress the imbalances.

Building on Success--Potential to Improve Coverage of Multiple Health Interventions Through Integrated Delivery With Routine Childhood Vaccination

Integrating delivery of nonvaccine interventions with childhood vaccinations has been suggested as a mechanism to accelerate progress toward Millennium Development Goals. Demographic health surveys from 28 sub-Saharan African countries were analyzed to determine potential coverage with 5 nonvaccine interventions that could be delivered to children, mothers, and families during routine infant vaccinations. Potential coverage levels were calculated among households with children aged 12-23 months, based on existing coverage of interventions and vaccinations. Most (>60%) children in families that had not received nonvaccine interventions had been vaccinated. If nonvaccine interventions could be delivered with vaccinations, the median percentage of households owning a bed net could increase from 46% to 92% and those with improved or treated sources of water from 55% to 91%. The median percentage of children who had received vitamin A supplementation could increase from 66% to 90%. Mothers who have been tested for human immunodeficiency virus could increase from 16% to 86%. In Africa, vaccination programs could provide a platform to substantially increase coverage of nonvaccine interventions. Studies are needed to investigate programmatic approaches to optimize the selection, adoption, and long-term utilization of these interventions and to assess the impact on vaccination and other intervention coverage.

Immunogenicity and Safety of an Inactivated Hepatitis A Vaccine Given with Measles-Mumps-Rubella Vaccine to 12-13 Month Old Turkish Children

Background: The epidemiology of hepatitis A in Turkey favor routine vaccination of children. This study assessed compatibility of a monovalent hepatitis A vaccine with the measles-mumps-rubella (MMR) combination vaccine used in the national immunization calendar at 12-15 months of age. Methods: Hepatitis A seronegative participants were randomized equally to hepatitis A vaccine followed by MMR vaccine 28 days later (Group A), MMR vaccine followed by hepatitis A vaccine 28 days later (Group B), or one dose each of hepatitis A and MMR vaccines given on Day 0 (Group C). All participants received a hepatitis A booster dose 6 months later. Results: A total of 470 seronegative (anti-hepatitis A concentration ≥20 mIU/mL) participants were randomized: 188 to Group A, 94 to Group B and 188 to Group C. The hepatitis A seroprotection rates (≥20 mIU/mL), 1 month after the first vaccination were 93.6% (Group A) and 92.7% (Group C) by a microparticle enzyme immunoassay (MEIA). Using a more sensitive electrochemiluminescence immunoassay (ECLIA), the corresponding seropositivity rates were 100 and 99.4%. Non-inferiority of seroprotection against hepatitis A was demonstrated for concomitant versus non-concomitant vaccination using ECLIA, but not MEIA. After booster, all participants had anti-hepatitis titers ≥20 mIU/mL and anti-hepatitis geometric mean concentrations of 5,078 mIU/mL (Group A), 3,271 mIU/mL (Group B) and 4,314 mIU/mL (Group C). Following primary vaccination, measles (≥120 mIU/mL) and mumps (≥ 10 AU/mL) seroprotection rates were 96.5% with both separate and concomitant vaccination. The rubella seroprotection (≥ 10 AU/mL) rates were 97.6 and 96.7% following separate and concomitant vaccination, respectively. Reactogenicity increased slightly with concomitant administration; both vaccines were well tolerated. Conclusions: The immune response to the hepatitis A vaccine was not impaired by concomitant administration with MMR vaccine. Non-inferiority of seroprotection was demonstrated with the more sensitive of two assays used to evaluate anti-hepatitis A antibody.

Safety and Immunogenicity of a 13-valent Pneumococcal Conjugate Vaccine in Healthy Infants and Toddlers Given With Routine Pediatric Vaccinations in Canada

The global distribution of pneumococcal disease and emergence of nonvaccine pneumococcal serotypes prompted the development of a 13-valent pneumococcal conjugate vaccine (PCV13), with broader coverage than 7-valent PCV (PCV7). This study compared compatibility of PCV13 and PCV7 with concurrently administered diphtheria, tetanus, acellular pertussis, inactivated poliovirus, Haemophilus influenzae type b vaccine, and meningococcal C conjugate vaccine (menC), and assessed the safety and immunogenicity of PCV13. In this double-blind, randomized trial, children received PCV7 or PCV13 at 2, 4, 6, and 12 months with routine vaccinations. One month following the infant series and toddler dose, the responses to Hib, pertussis, menC, and specific pneumococcal serotypes were measured. Safety and tolerability were assessed daily for 4 days by parents. Subjects received PCV13 (n = 300) or PCV7 (n = 303); immunogenicity assessment was completed in 265 and 268 subjects, respectively. There were no statistically significant differences between the groups in responses to Hib, pertussis, or menC after primary or booster vaccinations. More than 95% of subjects in the PCV13 group produced >0.35 μg/mL antibody to each pneumococcal serotype 1 month after the third dose, except with serotypes 23F (90%), 3 (80%), and 5 (87%). After the fourth dose, 98% to 100% of subjects achieved serotype-specific antibody concentrations >0.35 μg/mL, except for serotype 3 (85%). Safety and tolerability did not differ between groups with respect to local or systemic side effects. Responses to routine childhood vaccines did not differ with PCV7 or PCV13 coadministration. Serotype-specific pneumococcal antibody concentrations were protective. The safety profile of PCV13 was favorable.

Assessment of safety and immunogenicity of two different lots of diphtheria, tetanus, pertussis, hepatitis B and Haemophilus influenzae type b vaccine manufactured using small and large scale manufacturing process

Hib vaccine can be easily incorporated in EPI vaccination schedule as the immunization schedule of Hib is similar to that of DTP vaccine. To meet the global demand of Hib vaccine, SIIL scaled up the Hib conjugate manufacturing process. This study was conducted in Indian infants to assess and compare the immunogenicity and safety of DTwP-HB+Hib (Pentavac(®)) vaccine of SIIL manufactured at large scale with the 'same vaccine' manufactured at a smaller scale. 720 infants aged 6-8 weeks were randomized (2:1 ratio) to receive 0.5 ml of Pentavac(®) vaccine from two different lots one produced at scaled up process and the other at a small scale process. Serum samples obtained before and at one month after the 3rd dose of vaccine from both the groups were tested for IgG antibody response by ELISA and compared to assess non-inferiority. Neither immunological interference nor increased reactogenicity was observed in either of the vaccine groups. All infants developed protective antibody titres to diphtheria, tetanus and Hib disease. For hepatitis B antigen, one child from each group remained sero-negative. The response to pertussis was 88% in large scale group vis-à-vis 87% in small scale group. Non-inferiority was concluded for all five components of the vaccine. No serious adverse event was reported in the study. The scale up vaccine achieved comparable response in terms of the safety and immunogenicity to small scale vaccine and therefore can be easily incorporated in the routine childhood vaccination programme.

Assessment of hepatitis B immunization status after antineoplastic therapy in children with cancer

BACKGROUND AND OBJECTIVES:Hepatitis B is a disease that is preventable with vaccination. Antibody levels after vaccination may be affected by suppression of the immune system due to cancer therapy. Children with cancer have a high risk of hepatitis B virus (HBV) infection. We aimed to assess the pretreatment immunization status against HBV infection and the rate of continuity of immunization after therapy in children with cancer.DESIGN AND SETTING:Retrospective case review of patients treated from 2004 to 2008.PATIENTS AND METHODS:We reviewed the medical records of patients treated in the departments of pediatric hematology and oncology and collected data on immunization history and hepatitis B serology. Anti-HBs antibody titers were compared before and after treatment.RESULTS:This study included 159 (99 males, 60 females) children who had a serologic examination. Antineoplastic therapy had been given for acute leukemia (n=66), non-Hodgkin lymphoma (n=27), Hodgkin lymphoma (n=20), and solid tumors (n=46). Fifty-one patients had not been immunized against HBV prior to the therapy; HBV serology was negative in 49 of these patients and HBsAg was positive in 2 patients. Anti-HBs antibody positivity was present in 99 of 108 patients with an immunization history, whereas no vaccination response was present in 9 patients. The titer of anti-HBs antibody was decreased below the protection level in 33 (33%) patients with positive anti-HBs antibody, whereas the protection level was found to be maintained in 66 (67%) patients. The most significant decrease (63.6%) was observed in leukemia patients. Posttreatment HBsAg and HBV DNA positivity was detected in two of the patients with negative pretreatment serology, whereas no HBV infection developed in the group with positive anti-HBs antibody.CONCLUSIONS:This study demonstrated the importance of routine childhood vaccination in reducing the risk of HBV infection in patients with cancer.

Changes in serotype distribution of Haemophilus influenzae meningitis isolates identified through laboratory-based surveillance following routine childhood vaccination against H. influenzae type b in Brazil

Following routine childhood vaccination against Haemophilus influenzae type b (Hib) disease in Brazil in 1999, passive laboratory surveillance reported increasing numbers of non-b serotypes and nontypeable H. influenzae (NTHi) from meningitis cases. To characterize this increase, we analyzed data on 3910 H. influenzae isolated from cerebrospinal fluid or blood from meningitis cases that were sent to the national reference laboratory for serotyping from 1990 to 2008. Hib accounted for 98% of H. influenzae meningitis isolates received during 1990-1999 versus 59% during 2000-2008, while non-b serotypes increased from 1% to 19% and NTHi increased from 2% to 22% of H. influenzae isolates received during the two periods. Higher proportions of non-b serotypes and NTHi than Hib were isolated from blood rather than cerebrospinal fluid. Estimated incidence rates for H. influenzae meningitis for Sao Paulo state remained below 1 case per million population during 2000-2008, although annual incidence of NTHi meningitis (mean, 0.03 cases per 100,000 population) increased in several age groups. Changes in surveillance for H. influenzae following introduction of Hib conjugate vaccine likely contributed to increased numbers of non-b and nontypeable H. influenzae meningitis isolates received at the national reference laboratory.

An australian audit of vaccination status in children and adolescents with inflammatory bowel disease

BackgroundChildren and adolescents with inflammatory bowel disease (IBD) are at increased risk of vaccine preventable diseases (VPD). This includes invasive pneumococcal disease and influenza. The primary aim of this study was to describe compliance with current Australian guidelines for vaccination of children and adolescents diagnosed with IBD. A secondary aim was to review the serological screening for VPD.MethodsA random sample of patients (0-18 years at diagnosis), were selected from the Victoria Australia state based Pediatric Inflammatory Bowel Disease Register. A multi-faceted retrospective review of immunization status was undertaken, with hospital records audited, a telephone interview survey conducted with consenting parents and the vaccination history was checked against the primary care physician and Australian Childhood Immunization Register (ACIR) records. The routine primary childhood vaccinations and administration of the recommended additional influenza and pneumococcal vaccines was clarified.ResultsThis 2007 audit reviewed the immunization status of 101individuals on the Victorian Pediatric IBD database. Median age at diagnosis was 12.1 years, 50% were on active immunosuppressive therapy. 90% (38/42) [95% confidence intervals (CI) 77%; 97%] with complete immunization information were up-to-date with routine primary immunizations. Only 5% (5/101) [95% CI 2%; 11%] received a recommended pneumococcal vaccine booster and 10% (10/101) [95% CI 5%; 17%] had evidence of having ever received a seasonal influenza vaccine. Those living in rural Victoria (p = 0.005) and younger at the age of diagnosis (p = 0.002) were more likely to have ever received an influenza vaccine Serological testing, reviewing historical protection from VPD, identified 18% (17/94) with evidence of at least one serology sample.ConclusionThis study highlights poor compliance in IBD patients for additional recommended vaccines. A multi-faceted approach is required to maximize protection from VPD in this vulnerable special risk population.

Manifestations ophtalmologiques de la rubéole congénitale

Congenital rubella is a rare and serious disease including auditory neurological, cardiac, urinary, and ocular abnormalities. The eye complaints are often congenital cataract, congenital glaucoma, microphthalmia, and oculomotor disorders. We report the case of a 6-year-old girl presenting with a unilateral congenital cataract associated with congenital rubella. She was referred for complaints of high myopia in her right eye. She had a family history of cardiac and urogenital malformations, and presented deafness at birth. The ophthalmologic examination showed a microcornea and a unilateral dense congenital cataract in the right eye. B-scan ophthalmic ultrasound revealed a posterior microphthalmos. The anterior segment examination of the left eye was normal. Funduscopy revealed a salt-and-pepper appearance. Laboratory tests revealed a positive serology, confirming the congenital rubella. Given her complaints of loss of visual acuity in the right eye, the patient was operated on with a phacoaspiration implant in the capsular bag. The postoperative course was uneventful. The prevention of congenital rubella is based on routine vaccination of children. The association of cataract, congenital heart defects, and deafness must be systematically investigated as it may be more serious in association with systemic manifestations.

Closer to the Goal: Efforts in Measles Elimination in Germany 2010

Increasing 2-dose vaccination coverage has led to an interruption of endemic measles virus circulation in Germany. However, outbreaks after virus importation still occur and contribute to international transmission chains. Between 2003 and 2009, annual measles incidence ranged between 0.2 and 2.8 per 100,000 population. Immunization gaps have been identified especially in secondary-school students and young adults, which is also reflected by a shift in age distribution of reported measles cases toward older age groups. Stronger political commitment and standardized guidelines for outbreak containment were put in place in Germany in the past years, but the last step toward measles elimination cannot be made until the number of susceptible individuals has been further reduced. In addition to routine childhood vaccination, supplementary immunization activities are needed targeting school students and young adults to close critical immunization gaps. Intensification of public awareness and sound information on vaccinations are necessary to convince skeptics and remind the forgetful.

Update on Immunizations Commonly Used in the NICU

With few exceptions, it is currently recommended that all premature infants should receive routine childhood vaccines at the same chronologic age as term infants. Thus, neonatal nurses need to stay current on the recommendations for immunizations commonly used in the NICU setting. It is important for nurses to provide information that is reliable and verifiable with scientific evidence to the parents.

New Clinical Practice Guideline for Pain Management during Routine Childhood Vaccination — What Pharmacists Need to Know

New Clinical Practice Guideline for Pain Management during Routine Childhood Vaccination — What Pharmacists Need to Know
