On June 13, 1991, President George Bush announced in a White House ceremony a local planning effort to break down barriers and provide better access to immunization in six representative localities "to solve the problem of late immunization." (children need to be immunized appropriately by their second birthday, not just in time for school.). The community "Immunization Action Plans" (IAP) are one of several Federal, State, and local responses to an outbreak of measles that produced 27,600 cases and 89 deaths in 1990. The community effort and subsequent early childhood immunization plans around the country are also part of a much broader effort initiated by Secretary Sullivan as a Healthy People Year 2000 goal to increase immunization levels to at least 90 percent for the nation's children by their second birthday. These efforts also respond to 13 recommendations for improving immunization availability made by the National Vaccine Advisory Committee in January 1991. The recommendations focused on improvements in the management of immunization delivery and in methods for measuring immunization status, increasing appropriate consumer demand, and other prevention needs. Although measles prompted the action, the immunization initiative is aimed also at eight other communicable childhood diseases--diphtheria, tetanus, pertussis or whooping cough, poliomyelitis, mumps, rubella, and Haemophilus influenza type b that causes bacterial meningitis, and hepatitis B. Details are described of the immunization action plans developed by Dallas, TX; Maricopa County (Phoenix), AZ; South Dakota; Detroit, MI; San Diego, CA; and Philadelphia, PA, to ensure that children are fully immunized not just by the time they enter school but by age 2 years. The six were chosen by the Centers for Disease Control as representative of many without adequate childhood immunization coverage.

We studied case reports of bacterial meningitis and estimated its incidence per 100,000 in three areas of Osaka Prefecture which differed in population and vaccination schedule for the years of 1987 and 1988. To estimate incidence, we used a simple mathematical method derived from surveillance data for a reported number of exanthem subitum to obtain a coverage constant. With this coverage constant, we estimated the incidence of bacterial meningitis per 100,000 population for each area. In the Toyono area, with a population of about one million, the acellular pertussis vaccine series is started in children of three to six months of age and the incidence of bacterial meningitis per 100,000 was 1.95 in 1987 and 5.35 in 1988. Conversely, in Osaka City and Sakai City, with populations of about 2.6 and 0.8 million, respectively, the vaccine is given to children over two years of age and the incidence of bacterial meningitis per 100,000 was estimated to be 6.25 and 3.23 in 1987 and 14.62 and 1.07 in 1988, respectively. Thirteen cases of bacterial meningitis had been reported by Minoh City Hospital, in the Toyono area, and the Osaka City Infectious Disease Center in 1987 and 1988. Patients were seven males and six females and aged from less than a month to four years old. In six, the causal agent was Haemophilus influenzae type B, in three, Group B streptococcus, in two, Neisseria meningitidis and in one, Listeria monocytogenes. Only one of the thirteen patients had received an acellular pertussis vaccine.(ABSTRACT TRUNCATED AT 250 WORDS)

Haemophilus influenzae type b remains the major cause of bacterial meningitis in infants and children. Serum antibodies against the capsular polysaccharide--polyribosylribitolphosphate (PRP)--are protective, but its immunogenicity is poor in children under two years of age. Clinical trials actually in progress concerning an association of PRP with Bordetella pertussis are presented. Other vaccinal preparations are possible, such outer membrane protein, but prospects offered by polysaccharide-protein conjugates appear as the most encouraging.

Cefoperazone (CPZ) was given intravenously to 23 children with the following acute bacterial infections; 10 cases of pneumonia, 4 cases of urinary tract infection, 2 cases of purulent cervical lymphadenitis, 2 cases of pertussis pneumonia, 2 cases of septicemia, 1 case of osteomyelitis, 1 case of perforative peritonitis and 1 case of bacterial meningitis. Clinical effectiveness was obtained in 20 cases out of 23 cases and bacteriological effectiveness in 14 cases out of 17 cases. With CPZ, the following side effects developed; transient diarrhea in 1 case, asymptomatic eosinophilia in 2 cases. From the above clinical results, it is apparent that CPZ is a useful antibiotic for treating pediatric patients with various kinds of bacterial infections.

Haemophilus influenzae type b (Hib) is a major cause of serious bacterial infection in early childhood. In many developed countries it is the commonest cause of bacterial meningitis in children under 5 years of age. Serum antibodies to the polyribosylribitol phosphate (PRP) capsule, the main virulence factor of Hib, are protective, but the early vaccines containing purified PRP were poorly immunogenic in young children. However, 'second generation' protein conjugate vaccines have been shown to be immunogenic, effective and safe in young children. No serious adverse reactions to Hib vaccine have been reported to date. Clinically, the vaccine is indicated in the first few months of life and can be given at the same time as a primary course of diphtheria, pertussis and tetanus (DPT) immunisation. The vaccine should be given by deep subcutaneous or intramuscular injection. The only specific contraindication is a history of severe local reaction or a general reaction to previous Hib vaccination. Routine immunisation of infants under 6 months of age against Hib has become part of the regular primary schedule in many countries. In Finland this has resulted in a dramatic decline in Hib meningitis.

Vaccines comprising combinations of diphtheria, tetanus and pertussis (DTP) components with Haemophilus influenzae b polysaccharide--protein conjugates (DTP-Hib) are now available. Combinations of DTP-Hib with additional components such as inactivated poliomyelitis vaccine, hepatitis B vaccine, meningococcal and pneumococcal polysaccharide-protein conjugates are under development. Other combinations, such as Hib vaccine with meningococcal A, B and C components and possibly pneumococcal conjugates, or non-capsulated Haemophilus components combined with pneumococcal conjugates, developed against bacterial meningitis and otitis media respectively, are of potential interest. Combination vaccines against enteric infections and including potentially cholera, typhoid, ETEC, Shigella, rotavirus and possibly Campylobacter and Helicobacter components, may become available in the longer term. The control of these combinations is likely to be based on pharmacopoeial requirements for the individual components. However, the evaluation of combinations may not be straightforward and the interaction of the components with each other may influence reactogenicity, immunogenicity and stability and will complicate laboratory control tests. Indications of this have already arisen with some DTP-Hib combinations but are likely to increase as additional components are added. For example, the use of diphtheria and tetanus proteins as carriers for multiple polysaccharide conjugates may lead to excessive antitoxin production and epitope suppression of anti-polysaccharide responses. Other problems may result from competition for binding sites on adjuvant molecules. The requirements for new vaccine combinations need to be considered carefully and should not be made solely on assumptions based on the properties of individual components.

Smoking is associated with an increased risk of respiratory tract infection in adults. In children, exposure to cigarette smoke is a risk factor for respiratory tract infection and bacterial meningitis: Active smoking and passive exposure to cigarette smoke is also associated with carriage of some potentially pathogenic species of bacteria in both adults and children. The aims of the study were to determine the effect of active smoking on: (1) bacterial binding to epithelial cells; (2) expression of host cell antigens that act as receptors for some species; and (3) the effects of passive exposure to water-soluble components of cigarette smoke on bacterial binding. Flow cytometry was used to assess binding to buccal epithelial cells of the following species labelled with fluorescein isothiocyanate: Neisseria meningitidis, Neisseria lactamica, Streptococcus pneumoniae, Bordetella pertussis, Haemophilus influenzae, Moraxella catarrhalis, Staphylococcus aureus. Flow cytometry was also used to assess expression of host cell antigens which have been identified as bacterial receptors. For each species, binding to cells of smokers was significantly higher than to cells of non-smokers; however, expression of host cell antigens was similar on epithelial cells of both groups. Non-dilute cigarette smoke extract reduced binding of bacteria to epithelial cells, but dilutions between 1 in 10 and 1 in 320 enhanced binding. We conclude that smokers might be more densely colonised by a variety of potentially pathogenic bacteria. The enhanced bacterial binding to epithelial cells of smokers is not related to enhanced expression of host cell antigens that can act as receptors for some species, but possibly to components in the smoke that alter charge or other properties of the epithelial cell surface. Passive coating of mucosal surfaces with components of cigarette smoke might enhance binding of potentially pathogenic bacteria.

Effective immunization policies have markedly decreased the incidence of many lethal infectious diseases of childhood, including diphtheria, pertussis, and poliomyelitis, among others. In industrialized countries, relatively recent success in combating meningitis and sepsis has come with the implementation of universal immunization of infants against Haemophilus influenzae type b (Hib) and Streptococcus pneumoniae. These universal immunization programs have reduced disease incidence and related deaths by more than 90%. Thus 2 out of the 3 major bacterial causes of invasive disease in children have now been controlled, leaving Neisseria meningitidis as the obvious next target. Currently, mortality attributable to invasive meningococcal disease remains at a level consistent with that of several other major vaccine-preventable infections prior to the implementation of immunization strategies. Unlike Hib and pneumococcus, US immunization policy against invasive meningococcal disease currently focuses on adolescents, a strategy that has been notably less than successful given that the highest incidence of invasive meningococcal disease occurs early in the first year of life. Development of safe and effective vaccines that broadly protect infants against disease caused by N. meningitidis is the next logical step in the effort to prevent bacterial meningitis and sepsis. Their universal use in infancy would follow a well-established and notably successful path.

Vaccine-preventable diseases (VPDs) are costly at both the individual and societal levels. The most common VPDs recorded in travellers are enteric (typhoid or paratyphoid B) fever, acute viral hepatitis, influenza, varicella, measles, pertussis and bacterial meningitis. Travellers suffering from VPDs are frequently hospitalized, illustrating the point that VPDs are serious and expensive. Many travellers are not properly immunized before travel. In addition to individual consequences, VPDs can have public-health consequences if they are introduced or re-introduced by infected travellers returning to areas with susceptible populations. The international spread of poliomyelitis, Neisseria meningitidis serogroup W135 meningococcal infections, measles and influenza provides strong evidence of the role of international travel in the globalization of VPDs. The surveillance of the emergence, re-emergence or spread of VPDs is essential to adapt pre-travel advice and the responses to the VPD.

Hemophilus influenzae type b (Hib) is a leading cause of bacterial meningitis among infants and young children and the second leading cause of bacterial pneumonia deaths among children under 5 y. The overall case-fatality rate for Hib meningitis is 20-29%, and nearly 30% of surviving children suffer from major disabilities, while all invasive Hib disease (including meningitis) has a case fatality rate of 16% in India. Using the estimates from the Hib study, ~215,000 new cases of Hib pneumonia occur yearly in Indian children under the age of 5 y and result in over 61,000 deaths. This level of mortality is because of poor access to health services and poor health-seeking behavior by population, lack of laboratory infrastructure, and difficulty to diagnosis Hib disease among affected children. Disease burden is difficult to calculate. Even for those affected children who do reach healthcare facilities, the lack of quality health services and increasing prevalence of antibiotic-resistance makes treatment difficult for these children. Even in countries that have poor immunization coverage, indirect benefits of the Hib vaccine have been reported due to the herd effect. The Hib vaccine thus should be effective in India where Universal Immunization Programme (UIP) coverage is poor. Following the World Health Organization (WHO) recommendation that Hib-containing Pentavalent DTP vaccine (a combination vaccine that protects against five killer diseases: diphtheria, pertussis, tetanus, hepatitis B [hepB] and Hib) should be administered to every child in the world, the Government of India asked the National Technical Advisory Group on Immunization (NTAGI) to study the need for HepB and Hib vaccines in the Indian population. The India Ministry of Health and Family Welfare introduced Pentavalent DTP vaccines in the UIP with the aim of reducing the burden of Hib-related morbidity and mortality.
