RESUMO
The Advisory Committee on Vaccines of the Spanish Association of Paediatrics (CAV-AEP) annually publishes the immunisation schedule which, in our opinion, estimates optimal for children resident in Spain, considering available evidence on current vaccines. We acknowledge the effort of the Ministry of Health during the last year in order to optimize the funded unified Spanish vaccination schedule, with the recent inclusion of pneumococcal and varicella vaccination in early infancy. Regarding the funded vaccines included in the official unified immunization schedule, taking into account available data, CAV-AEP recommends 2+1 strategy (2, 4 and 12 months) with hexavalent (DTPa-IPV-Hib-HB) vaccines and 13-valent pneumococcal conjugate vaccine. Administration of Tdap and poliomyelitis booster dose at the age of 6 is recommended, as well as Tdap vaccine for adolescents and pregnant women, between 27-36 weeks gestation. The two-dose scheme should be used for MMR (12 months and 2-4 years) and varicella (15 months and 2-4 years). Coverage of human papillomavirus vaccination in girls aged 11-12 with a two dose scheme (0, 6 months) should be improved. Information for male adolescents about potential beneficial effects of this immunisation should be provided as well. Regarding recommended unfunded immunisations, CAV-AEP recommends the administration of meningococcal B vaccine, due to the current availability in Spanish communitary pharmacies, with a 3+1 scheme (3, 5, 7 and 13-15 months). CAV-AEP requests the incorporation of this vaccine in the funded unified schedule. Vaccination against rotavirus is recommended in all infants. Annual influenza immunisation and vaccination against hepatitis A are indicated in population groups considered at risk.

Meningococcal invasive disease, including the main clinical presentation forms (sepsis and meningitis), is a severe and potentially lethal infection caused by different serogroups of Neisseria meningitidis. Meningococcal serogroup B is the most prevalent in Europe. Most cases occur in children, with a mortality rate of 10% and a risk of permanent sequelae of 20-30% among survivors. The highest incidence and case fatality rates are observed in healthy children under 2-3 years old, followed by adolescents, although it can occur at any age. With the arrival in Spain of the only available vaccine against meningococcus B, the Advisory Committee on Vaccines of the Spanish Association of Paediatrics has analysed its preventive potential in detail, as well as its peculiar administrative situation in Spain. The purpose of this document is to publish the statement of the Committee as regards this vaccination and the access to it by the Spanish population, taking into account that it has been only authorized for people at risk. The vaccine is available free in the rest of Europe for those who want to acquire it, and in some countries and regions it has been introduced into the systematic immunisation schedules. The Committee considers that Bexsero® has a profile of a vaccine to be included in the official schedules of all the Spanish autonomous communities and insists on the need for it to be available in pharmacies for its administration in all children older than 2 months.

The Advisory Committee on Vaccines of the Spanish Association of Paediatrics updates the immunisation schedule every year, taking into account epidemiological data as well as evidence on the safety, effectiveness and efficiency of current vaccines, including levels of recommendation. In our opinion, this is the optimal vaccination calendar for all children resident in Spain. Regarding the vaccines included in the official unified immunization schedule, the Committee emphasizes the administration of the first dose of hepatitis B either at birth or at 2 months of life; the recommendation of the first dose of MMR and varicella vaccine at the age of 12 months, with the second dose at the age of 2-3 years; DTaP or Tdap vaccine at the age of 6 years, followed by another Tdap booster dose at 11-12 years old; Tdap strategies for pregnant women and household contacts of the newborn, and immunization against human papillomavirus in girls aged 11-12 years old with a 2 dose scheme (0, 6 months). The Committee reasserts its recommendation to include vaccination against pneumococcal disease in the routine immunisation schedule, the same as it is being conducted in Western European countries. The recently authorised meningococcal B vaccine, currently blocked in Spain, exhibits the profile of a universal vaccine. The Committe insists on the need of having the vaccine available in communitary pharmacies. It has also proposed the free availability of varicella vaccines. Their efectiveness and safety have been confirmed when they are administred from the second year of life. Vaccination against rotavirus is recommended in all infants. The Committee stresses the need to vaccinate population groups considered at risk against influenza and hepatitis A.

The prevalence of hepatitis B virus (HBV) infection was studied in 346 subjects (148 employees and 198 mentally retarded) in four institutions for the mentally subnormal in Vizcaya-Spain. The prevalence of markers in the overall group was 32.6%; 13.5% in the employees and 46.9% in the mentally retarded. Early age and institutionalization time increases the risk of infection in the mentally retarded group, but not in the employees group. 220 subjects (118 employees and 102 mentally retarded) had negative HBV markers and were vaccinated with recombinant-DNA hepatitis B vaccine. The immunogenicity was 80% and the weight-height index the only factor implicit in the group of subjects no seroconverters. The reactogenicity of vaccine was 6.7%.

The Advisory Committee on Vaccines of the Spanish Association of Paediatrics (CAV-AEP) updates the immunisation schedule every year, taking into account epidemiological data as well as evidence on safety, effectiveness and efficiency of vaccines. The present schedule includes levels of recommendation. We have graded, as routine vaccinations, those that the CAV-AEP consider all children should receive; as recommended those that fit the profile for universal childhood immunisation and would ideally be given to all children, but that can be prioritised according to the resources available for their public funding; and as risk group vaccinations those that specifically target individuals in special situations. Immunisation schedules tend to be dynamic and adaptable to ongoing epidemiological changes. Based on the latest epidemiological trends, CAV-AEP recommends the administration of the first dose of MMR and varicella vaccines at age 12 months, with the second dose at age 2-3 years; the administration of DTaP or Tdap vaccine at age 4-6 years, always followed by another Tdap dose at 11-12 years; and the three meningococcal C scheme at 2 months, 12 months and 12 years of age. It reasserts its recommendation to include vaccination against pneumococcal disease in the routine immunisation schedule. The CAV-AEP believes that the coverage of vaccination against human papillomavirus in girls aged 11-12 years must be increased. Universal vaccination against varicella in the second year of life is an effective strategy, and the immediate public availability of the vaccine is requested in order to guarantee the right of healthy children to be vaccinated. Vaccination against rotavirus is recommended in all infants due to the morbidity and elevated healthcare burden of the virus. The Committee stresses the need to vaccinate population groups considered at risk against influenza and hepatitis A. The recently authorised meningococcal B vaccine has opened a chapter of hope in the prevention of this disease. In anticipation of upcoming national and international studies, the Committee recommends the vaccine for the control of disease outbreaks, and insists on the need to be available in pharmacies. Finally, it emphasises the need to bring incomplete vaccinations up to date following the catch-up immunisation schedule.

The Advisory Committee on Vaccines of the Spanish Association of Paediatrics establishes annual recommendations on influenza vaccination in childhood before the onset of influenza season. Routine influenza vaccination is particularly beneficial when the strategy is aimed at children older than 6 months of age with high-risk conditions and their home contacts. The recommendation of influenza vaccination in health workers with children is also emphasized.

The Advisory Committee on Vaccines of the Spanish Paediatric Association updates annually the immunization schedule, taking into account epidemiological data as well as evidence of the effectiveness and efficiency of vaccines. This vaccination schedule includes grades of recommendation. The committee has graded as universal vaccines those that all children should receive, as recommended, those with a profile of universal vaccines of childhood and as are desirable those that all children may receive, but that can be prioritized based on public funding resources and for risk groups, targeting those groups of people in epidemiological situations of risk. The Committee considers as a priority to achieve a common immunization schedule for Spain. The Committee reaffirms the recommendation to include pneumococcal vaccination in the routine vaccination schedule. Vaccination against varicella in the second year of life is an effective strategy and therefore a desirable goal. Given the morbidity and high burden on the health care system, vaccination against rotavirus is recommended for all infants. Due to the current problems of availability of both vaccines, associated with the recent finding of circovirus, the committee urges that rotavirus vaccination is restarted as soon as possible as it is considered a desirable health benefit for all children in our country. The Committee adheres to the recommendations of the National Health Coordination Council in reference to routine vaccination against HPV for all girls aged 11 to 14 years and stresses the need to vaccinate all patients with risk factors for these diseases against influenza and hepatitis A. Finally, it stresses the need to update incomplete immunizations using accelerated immunization schedules.

OBJECTIVE: The objective of this study was to perform a pooled analysis of the immunogenicity and reactivity results obtained in 2 trials carried out in Spain with a combined DTP-HB vaccine. PATIENTS AND METHODS: Vaccine was administered according to one of two existing vaccination schedules: 2-4-6 and 3-5-7 months of age. Blood samples for antibody determination were obtained 3-6 weeks after the third dose. Anti-diphtheria, anti-tetanus and anti- B. pertussis antibodies were measured by ELISA and anti-HB by radioimmunoassay. Local and general signs and symptoms were recorded by the parents on diary cards for a 4-day follow-up period after each vaccination. RESULTS: A total of 231 infants received three doses of DTP-HB vaccine. All of these doses were accompanied by the corresponding diary card (693 data points for the evaluation of reactogenicity). Two-hundred and nineteen subjects ere included in the analysis of immunogenicity. After the full vaccination course, all subjects had sero-protective titers against diphtheria, tetanus and hepatitis B and were sero-positive of B. pertussis. Geometric mean titers of anti-HB antibodies was 1986 mIU/ml. Pain at the injection site (64%) and unusual crying (71.5%) were the most frequently reported local and general symptoms, respectively. Fever (rectal temperature > or = 38 degrees C) was reported after 46% of the doses, but was considered as severe (> 39.5 degrees C) only in 5 cases. CONCLUSIONS: These results show that this combined DTP-HB vaccine induced a strong immune response to all vaccine components. The safety profile of this DTP-HB is similar to that of classical DTP vaccines.

The cases of tuberculosis in the Pediatric Units of the Basque Autonomous Community during the period of 1980-89 were studied. The annual incidence rate in the 0-4 year old age group was 5.8 per 100.00 in Biscay (95% confidence interval: 4.0-7.6), 5.9 (2.3-9.5) in Alava and 16.7 (12.7-20.7) in Guipúzcoa. Out of the 263 registered cases, 55 (21%) corresponded to meningitis and/or miliaria, 194 (74%) to respiratory tuberculosis and 14 (5%) to other clinical forms. Of these cases, the diagnosis in 83 (32%) was based on results from microbiological cultures, in 8 (3%) on histological examinations and in the remaining 172 (65%) on other diagnostic criteria. In 226 cases (86%) no scars were found nor were there any antecedents of BCG vaccination. In 32 patients (12%), there were scars or antecedents of BCG vaccinations and in 5 cases no information was available. The estimated protective effect of the BCG vaccination in the 0-4 year old group was 88% and in the 5-14 year old group 63%. We recommend that the efficiency of the BCG vaccination program be studied in order to assess the need of this program.

BACKGROUND: Streptococcus pneumoniae is the most commonly reported bacterial cause of bacteremia and bacteremic pneumonia and the second most frequent cause of meningitis. OBJECTIVE: To establish the incidence, characteristics and serotypes causing invasive pneumococcal disease in children aged less than 5 years in two Autonomous Communities in Spain, the Basque country and Navarre, between 31 May 1988 and 1 June 2001. PATIENTS AND METHODS: We performed a descriptive, observational and retrospective study. The study population was composed of children diagnosed with invasive pneumococcal disease in the public and private hospitals with a pediatrics departments. Invasive pneumococcal disease was defined as isolation of S. pneumoniae in blood, cerebrospinal fluid or any other sterile biological fluid. Medical records were reviewed and demographic and diagnostic variables were analyzed. Age-adjusted frequency rates were established for both regions using direct standardization. Confidence intervals were obtained by Poisson distribution. SPSS for Windows 10.0 and Epidat 2.1 were used for the analysis. Data were obtained from the 1999 municipal population census. RESULTS: One hundred seventy-one children aged 0-5 years were included. A total of 40.9 % (70 patients) were aged less than 12 months and 68.4 % were aged 0-2 years; 16.4 % had received drug therapy before diagnosis. The most common forms of presentation were occult bacteremia (45.6 %), bacteremic pneumonia (27.5 %) and meningitis (14.6 %). The most frequent complications involved the respiratory tract, with pleural effusion in 23 % of cases of pneumonia. The standardized annual incidence rate of invasive pneumococcal disease (cases per 100,000) in children aged 0-59 months was 58.82 (95 % CI: 27.99-89.65) in Navarre and 55.35 (95 % CI: 38.81-71.88) in the Basque Country. In children aged 0-23 months, the overall incidence was 93.49 cases per 100,000 children (95 % CI: 77.32-112.04) and in infants aged 0-11 months, it was 110,21 cases per 100,000 children (95 % CI: 85.91-139.24). The incidence rates for meningitis and bacteremia in children aged 0-23 months was 15.98 (95 % CI: 9.76-24.68) and 51.14 (95 % IC: 39.38-65.30) cases per 100.000 children. Fifty-nine strains were serotyped. The most frequent serotypes/groups were 1, 4, 6B, 14, 18C, 19 and 23F. A total of 52.15 % of the serotypes were penicillin-susceptible and 93 % were cefotaxime-susceptible. The serotypes/groups with the highest rates of resistance were 6B, 14,19, 23F and 35. CONCLUSION: Our incidence rates are similar to those observed in other countries such as the United States and are higher than those reported for the rest of Europe. Vaccine coverage is similar to that described in other articles.

OBJECTIVE: To determine the incidence, as well as the implicated serotypes and patterns of antibiotic resistance of Streptococcus pneumoniae meningitis in Spanish children. MATERIAL AND METHOD: We performed a prospective, multicenter study in five Autonomous Communities (Catalonia, Galicia, Madrid, Navarre and the Basque Country) for 1 year (1 February 2000 31 January 2001). All children aged 0-14 years with pneumococcal meningitis from all the hospitals in the Autonomous Communities studied were included. Diagnosis was based on clinical findings and isolation of S. pneumoniae in the cerebrospinal fluid/blood using routine methods or polymerase chain reaction. Serotyping was performed using the guellung reaction and/or immunoblotting and susceptibility to antibiotics was evaluated by the technique of agar dilution. The pediatric population aged 0-14 years in the Autonomous Communities studied comprises 2,290,304 children. RESULTS: Fifty-two cases were identified. One patient was aged less than 2 months old, 25 (48 %) were aged 2-12 months, and 12 patients (23 %) were aged 12-24 months. The annual incidence per 100,000 children aged between 1 and 2 years was 17.75 cases (95 % CI: 11.59 26.01) and 8.39 cases (95 % CI: 4.67 15.79) respectively, and that for children in the first 2 and 5 years of life was 13.13 (95 % CI: 9.29 18.02) and 6.29 (95 % CI: 4.57 8.,45) cases respectively. Nearly half the strains isolated (47.6 %) showed reduced sensitivity to penicillin. The most frequent serotype was 19F (12 cases [28.6 %]). Eighty percent of the isolated serotypes were included in the formula of the heptavalent conjugate vaccine. CONCLUSIONS: The incidence of pneumococcal meningitis in children from five Spanish Autonomous Communities is high, nearly twice that found in a prior retrospective studied performed in the same population 1-3 years previously. Almost all the isolated serotypes were included in the heptavalent conjugate vaccine. Half the strains showed reduced sensitivity to penicillin.

The immunogenicity of oral diphtheria, pertussis, tetanus, (DPT) and polio vaccines was examined. Six hundred seventy-seven children (Group I) were given hepatitis B vaccine at 0, 2, and 6 months of age and the oral DPT-polio vaccines were administered at 2, 4 and 6 months of age. A control group of 731 children (Group II) received only oral DPT-polio vaccines. In both groups the vaccine efficacy against poliomyelitis was 96% for serotype I and 100% for serotype II. For serotype III, the vaccine efficacy was 98% and 97% for groups I and II, respectively. In both groups 97% of the children had antibodies against B. pertussis and all children were positive for tetanus and diphtheria. No immune interference between the oral DPT and polio vaccines and the hepatitis B vaccine when they were given simultaneously could be demonstrated as the immune response to the DPT and polio vaccines were identical in both groups. It can be concluded that the simultaneous administration of the hepatitis B vaccine with the DPT and polio vaccines did not interfere with the immune response to the other antigens.

Pneumococcal disease is a major cause of morbidity, hospitalization and mortality. Two age groups show a greater incidence and severity of the disease: children under the age of 5 years (mainly during the first 2 years of life) and adults aged more than 65 years. The heptavalent pneumococcal conjugate vaccine, which was commercialized in Spain in June 2001, is efficacious in children aged less than 2 years and, unlike the non-conjugate 23-valent vaccine, it induces immunological memory. In Spain the heptavalent vaccine covers 80 % of serotypes causing pneumococcal invasive disease and acute otitis media in children aged 2-59 months. The heptavalent vaccine has been shown to be immunogenic, efficacious and safe. It has proven efficacy in the prevention of invasive disease caused by the seven vaccine serotypes. In addition, it significantly decreases pneumonia and also prevent acute otitis media. The vaccine is preferably indicated in children aged less than 2 years; children aged 2-5 years may also benefit from the vaccine but those in risk groups should be prioritized. Greater knowledge of the epidemiology of pneumococcal disease and the efficiency of this vaccine in Spain will determine whether it should be included in the immunization schedule.
