Increasing numbers of immigrants from the former Soviet Union are settling in the United States each year, making it imperative for clinicians to know how to find and interpret immigrant children's immunization records. Records show that these children have usually received immunizations against tetanus, diphtheria, pertussis, poliomyelitis, measles, mumps and tuberculosis (BCG). They are occasionally vaccinated against influenza, smallpox and tularemia, but never against rubella, hepatitis B or H. influenzae meningitis. The Soviet immunization schedule differs significantly from the U.S. schedule only in BCG vaccine and polio immunization. Contrary to widespread belief in the United States, BCG vaccination does not necessarily render a child's tuberculin skin test positive, and it certainly does not confer total immunity to tuberculosis. MMR vaccination is essential for all Soviet immigrant children. A single update of all the other immunizations may be a wise approach when handling Soviet children's immunizations.

This is the first study in children from the United States that evaluates the immunogenicity of and adverse reactions to the Connaught/Biken two-component acellular pertussis vaccine compared with whole-cell pertussis vaccine when given as a primary immunization series at 2, 4, and 6 months of age. Three hundred eighty infants were studied; 285 received acellular diphtheria-tetanus toxoids-pertussis (DTP (ADTP)) and 95 received whole-cell DTP (WDTP). Following the third dose, ADTP vaccination produced higher antibody responses than WDTP to lymphocytosis-promoting factor (enzyme-linked immunosorbent assay IgG geometric mean titer (GMT) = 131 vs 9 and Chinese hamster ovary cell assay GMT = 273 vs 16) and to filamentous hemagglutinin (IgG GMT = 73 vs 10) (all P less than .0001). Agglutinin responses were higher in WDTP compared with ADTP recipients (GMT = 50 vs 37; P = .02). Local reactions were fewer for all three doses following ADTP vaccination. Fever, irritability, drowsiness, anorexia, vomiting, and unusual crying all occurred less frequently in ADTP compared with WDTP recipients for one or more of the three doses. We conclude that this two-component ADTP vaccine when given as a primary series produces greater immunogenicity and fewer adverse effects than the currently licensed WDTP vaccine.

The immunogenicity and safety of a new Haemophilus influenzae type b conjugate vaccine, PRP-T, was studied in 107 infants from the Oxford district. The vaccine was given concurrently with diphtheria, pertussis, tetanus, and polio vaccines at 2, 3, and 4 months of age. Symptoms after immunisation were recorded by a parent. Sera were obtained before the first immunisation and at 5 months of age and the antibodies were measured by both radioimmunoassay and enzyme linked immunosorbent assay (ELISA). No serious adverse reactions were observed and there was no increase in the incidence of expected minor side effects. By radioimmunoassay, the geometric mean titre of serum anticapsular antibody increased from 0.09 micrograms/ml before immunisation to 5.01 micrograms/ml after three immunisations. Ninety eight per cent of children had antibody concentrations consistent with protection (greater than or equal to 0.15 micrograms/ml). IgG antibody concentrations measured by ELISA correlated well with total antibody concentrations measured by radioimmunoassay (r = 0.864). These results provide encouragement that routine immunisation against H influenzae type b at 2, 3, and 4 months of age, could prevent most cases of disease in children in the UK.

Immune efficacy and persistency were studied by comparison of two-dose immunization of adsorbed DPT at one and two month interval and two & three dose immunization of unadsorbed DPT during 1970s and 1980s. Serological investigation showed that antibody response to diphtheria, tetanus were elicited in four groups of children after primary immunization, but, the antibody response to pertussis was poor in children immunized with unadsorbed DPT. Three kinds of antibody titres were increased significantly after booster immunization. Antibody persists more than eight years for diphtheria, about five years for tetanus and only three years for pertussis. Comparison of two-dose immunization of adsorbed DPT at two months interval and three dose immunization of unadsorbed DPT showed that antibody response to diphtheria, pertussis and tetanus were satisfied in adsorbed DPT than in unadsorbed one after primary immunization, and there is no difference between primary and booster immunization.

In 1924 Ramon described the inactivation of diphtheria toxin by formaldehyde treatment. This method allowed the introduction of mass vaccination against diphtheria and tetanus and opened the way to the inactivation of viruses by chemical treatment. In this review we describe the use of genetic manipulations for the inactivation of pertussis toxin. The toxin inactivated by this new method is an antigen superior to those obtained by chemical treatment and has been used to develop a new vaccine against whooping cough.

A human hyperimmune globulin termed bacterial polysaccharide immune globulin (BPIG) has been prepared from plasma donors immunized with Haemophilus influenzae type b (Hib), pneumococcal, and meningococcal vaccines. At a dose of 0.5 ml/kg, BPIG increased levels of antibody to Hib by greater than 0.15 microgram/ml within 4-6 h and by 2-4 micrograms/ml at 72 h. Thereafter, antibody declined, with a mean half-life of 27 days. BPIG treatment of Apache infants did not impair their active antibody responses to concurrently administered diphtheria-tetanus-pertussis or Hib oligosaccharide-diptheria CRM197 conjugate vaccines. In high-risk Apache infants, BPIG given at 2, 6, and 10 months of age provided significant protection from invasive Hib infection during infancy. Thus, BPIG may have utility in the prevention of Hib infections in high-risk patients who cannot be immunized adequately with Hib conjugate vaccines.

A community health professor analyzed 1986-1989 data on selected primary health care (PHC) services (immunizations, prenatal care, and delivery) to examine the progress of PHC interventions in the rural Odukpani local government area (LGA) in Cross River State, Nigeria. Coverage for the diphtheria-pertussis-tetanus (DPT) and oral poliovirus (OPV) vaccines increased steadily over time (DPT-1 and DPT-2 18-32%; DPT-3 3-28%; OPV-1 18-35%; OPV-2 8-32%; and OPV-3 3-28%). On the other hand, measles and bacille Calmette-Guerin (BCG) vaccine coverage fell (42-28% and 49-31%, respectively). Tetanus toxoid coverage was 13% in 1986 and fell to 12% in 1987 and increased above original levels in 1988 (17%). Odukpani LGA vaccine coverage figures were below national coverage figures. The proportion of all 15-49 year old women using antenatal services fluctuated around 20% during this period, but the percent increase in utilization of antenatal services increased from 0-14%. Overall, the proportion of health worker (HW) attended deliveries increased (e.g., 56-69% during 1988-1989) while the proportion of traditional birth attended (TBA) deliveries decreased (e.g., 45-31% during 1988-1989). On the other hand, in 1986-1987, TBA deliveries rose (39-47%) while HW attended deliveries fell (62-53%). Traditional birth attendants did receive training to reduce maternal and child mortality. There was a real possibility of underreporting in this LGA. These results do indicate, however, that the PHC system has effected at least modest increases in specific interventions. This pilot approach can serve as a practical means to monitor implementation of PHC efforts.

The occurrence of subcutaneous nodules at the injection site is one of the complications of diphtheria-tetanus-pertussis-poliomyelitis vaccination, but the causes and mechanisms involved are still poorly understood. An experimental study in the New Zealand rabbit enabled us to determine the frequency of occurrence of these nodules, how long they persist and the histopathologic features of the cells involved. Aluminium (Al) assays by electrothermal atomic absorption spectrometry allowed us to study concentrations both in nodules and the organism (serum, normal skin). The results show an absence of Al diffusion outside nodules, a correlation between infiltrate intensity and Al concentration in nodules and modifications in the histological constituents of nodule cells. The histological picture indicates a foreign body reaction to Al. All these data underscore the role of Al in the formation of early postvaccinal nodules at the injection site.

Low immunization rates among US preschool children suggest a need for improved immunization practices. Immunization and encounter records were reviewed to ascertain immunization rates and missed opportunities for vaccine administration among 515 preschool children who were active patients at a hospital-based primary care center serving lower socioeconomic status families in Rochester, NY. The point prevalence at a mean age of 4.4 years for lack of one or more recommended immunizations was 27%; 7% were missing measles-mumps-rubella, 18% were missing Haemophilus influenzae type b, 8% were missing two or more diphtheria-tetanus-pertussis, and 4% were missing two or more oral poliovirus immunizations. A visit was counted as a missed opportunity if an immunization was due but not given. Over the period from birth through age 36 months, 422 (82%) of children missed at least one immunization opportunity. For these 422 children, there was a mean of 7.2 missed opportunities per child. Although 64% of missed opportunities occurred at an acute illness visit, 36% occurred at well-child, administrative, follow-up, or chronic illness visits. Review of 200 medical records randomly selected from all opportunities at acute illness visits found no contraindication in 63% (50% nonfebrile infectious disease, 13% minor noninfectious problems). Findings for random samples of 100 missed diphtheria-tetanus-pertussis opportunities for children aged 2 to 6 months and 100 missed measles-mumps-rubella opportunities for children 15 to 24 months were similar to findings for the sample of all acute illness visits. Emergency department visits, where immunization records were not readily available, accounted for 18% of missed opportunities.(ABSTRACT TRUNCATED AT 250 WORDS)

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.
