An acellular pertussis-component combined diphtheria and tetanus toxoids, and pertussis (APDT) vaccine adsorbed was compared with a licensed whole-cell pertussis-component combined diphtheria and tetanus toxoids, and pertussis (DTP) vaccine adsorbed for reactogenicity and immunogenicity when given as the fifth DTP immunization to eighty-two 4- to 6-year-old children. The reaction rates with both vaccines were low; APDT vaccine recipients had significantly less pain and warmth at the injection site than did DTP vaccine recipients. Antibody responses to pertussis antigens (lymphocytosis-promoting factor, filamentous hemagglutinin, and agglutinogens) and to diphtheria and tetanus toxoids were all brisk. The APDT vaccine recipients had a more marked response in antibodies to filamentous hemagglutinin and a less marked response in agglutinins than whole-cell vaccine recipients. On the day after immunization, both APDT and DTP vaccine recipients had an increase in mean leukocyte and neutrophil counts. This APDT vaccine is immunogenic and less reactogenic than a DTP vaccine with a whole-cell pertussis component when administered as a booster to 4- to 6-year-old children.

Researchers have found that physiologic changes occur that indicate infants do perceive pain. In the study, infants were audiovideotaped while receiving the first diphtheria-pertussis-tetanus (DPT) injection to document their responses to an assumed painful stimulus. The vocalization of crying and some facial movements were identified as behaviors associated with receiving the DTP injection. These findings support the need for nurses to use a multidimensional assessment when caring for infants believed to be having pain.

To determine the effect of prophylactic acetaminophen on reactions after diphtheria and tetanus toxoids and pertussis vaccination, 282 children received either acetaminophen or placebo in a double-blind, randomized fashion before and 3, 7, 12, and 18 hours after vaccination. Fever and local and systemic reactions were monitored. Switching to known acetaminophen was permitted if the patient's temperature was 38.9 degrees C or higher or for moderate pain. Overall, the reaction score of acetaminophen recipients was significantly less than that of placebo recipients. The rates of occurrence of fever and fussiness and the degree of pain at the injection site were significantly reduced by acetaminophen administration. Children who received acetaminophen were less likely to be switched to "open" acetaminophen than placebo recipients. It is concluded that prophylactic acetaminophen as given in this study had a moderating effect on fever, pain, and fussiness after diphtheria and tetanus toxoids and pertussis immunization.

Although the conventional Bordetella pertussis vaccine, which consists of killed whole organisms, has been shown to be effective in preventing disease, it has been associated with transient local and systemic reactions and may produce encephalopathy, though rarely. A new acellular pertussis vaccine containing partially purified protein antigens, filamentous hemagglutinin, and lymphocytosis-promoting factor hemagglutinin has been developed for use in Japan. We compared the immunogenicity and reactogenicity of conventional and acellular pertussis vaccine. Forty children aged 4 to 6 years and 40 children aged 18 to 24 months, all previously immunized at appropriate times with conventional diphtheria and tetanus toxoids and pertussis vaccine, were enrolled. We randomly assigned children to receive either conventional pertussis vaccine or acellular pertussis vaccine in a double-blind fashion. The diphtheria and tetanus components in both preparations were identical. Equivalent rises in pertussis agglutinin titers and antibodies to filamentous hemagglutinin and lymphocytosis-promoting factor hemagglutinin were measured in both vaccine groups at both ages that we studied. However, reaction rates to the two vaccines in both age groups were strikingly different. Acellular pertussis vaccine was significantly less reactogenic for fever, pain, fretfulness, abnormal gait, and local reactions at the vaccine administration site. If studies in progressively younger children confirm its reduced reactogenicity and equal immunogenicity, and if large-scale trials indicate its efficacy, the acellular pertussis vaccine may be a more appropriate candidate than the current vaccine.

Because a large proportion of preschool children failed to present for free diphteria-pertussis-tetanus (DPT) immunization in a poor, rural area of the Philippines, the authors undertook an epidemiological analysis of their characteristics. The parents of 159 children were interviewed to determine the demographic, attitudinal, knowledge, and administrative correlates of immunization status. Logistic regression was used to model immunization status. Children were less likely to be immunized if they had a high score on an Adversity Index (composed of measures of the weather, the number of visits the team made, the distance, the appropriateness of the time of day, and miscellaneous problems), if they received health care from a native mother and child health specialist, if a parent was not on the town council, and if pain was an important deterrent. By contrast, many demographic and attitudinal measures that have traditionally been thought to predict health behavior were not useful discriminators. Recommendations are made for immunization program management. The general use of this method for program planning is elaborated.

It is generally presumed that children who have had reactions to diphtheria-tetanus-pertussis (DTP) immunization will be more likely to have similar reactions or more severe reactions upon subsequent immunization. To evaluate this contention, we studied the rates of selected reactions occurring within 48 hours of primary DTP immunization in 1,241 infants less than one year of age. Both local and systemic reactions were significantly more frequent following subsequent DTP immunization if present following a prior immunization. The rates of local reactions following subsequent DTP immunization as a function of previous reactions were as follows (no prior reactions/prior reaction): local redness greater than or equal to 2.5 cm, 12.5%/25.5% (p less than 0.0001); local swelling greater than or equal to 2.5 cm, 16.8%/29.0% (p less than 0.0001); local pain, 37.4%/56.4%; (p less than 0.0001). The rates of systemic reactions as a function of previous reactions were as follows (no prior reactions/prior reaction): drowsiness, 24.9%/42.8% (p less than 0.0001); fretfulness, 47.5%/64.7% (p less than 0.0001); vomiting, 4.8%/11.2% (p = 0.0084); anorexia 16.0%/26.3% (p = 0.0001); fever greater than or equal to 38 degrees C, 37.6%/58.5% (p less than) 0.0001); persistent crying, 2.6%/4.5% (p = 0.3557). In addition, infants who experienced a fever greater than or equal to 38 degrees C on the first of two immunizations were more likely to have a temperature greater than or equal to 39 degrees C following the second immunization, 4.2% vs. 12.4% (p = 0.0017). These data strongly support the presumption that children who have had previous reactions following DTP immunization are more likely to have similar reactions upon subsequent immunization.

Local and less serious systemic reactions are frequent following immunization with diphtheria-tetanus-pertussis (DTP) vaccine. The effects of injection site, manufacturer, previous reactions, and dosage reduction upon subsequent reactions to DTP immunization were investigated. Local reactions, notably pain and swelling, were less common when the immunization was given in the buttocks than in the thigh. No injection site was consistently associated with lower systemic reaction rates. There was no significant difference in the rate of more serious reactions by vaccine manufacturer. Differences in rates of less serious reactions by manufacturer were observed but seemed to be related to vaccine lot differences rather than the specific vaccines. In a subset of 772 children, in whom data regarding sequential reactions were available, it was noted that all three reactions investigated--local redness, temperature greater than or equal to 39 degrees C, and persistent crying longer than one-half hour--were two to three times more frequent on a subsequent immunization when present on a prior vaccination than if not present on a prior vaccination than if not present previously. One hundred children received a half dose of DTP vaccine because of a less serious reaction associated with prior immunization. In all instances, they had significantly less serious local reactions as well as notable differences in temperature, drowsiness, and persistent crying.

We examined, in 2 phases, the influence of postevent suggestions on children's reports of their visits to a pediatrician. Phase 1 examined the effect of giving one of 3 types of feedback to 5-year-old children immediately following their Diphtheria Pertussis Tetanus (DPT) inoculation. Children were given pain-affirming feedback (the shot hurt), pain-denying feedback (the shot did not hurt), or neutral feedback (the shot is over). 1 week later, they did not differ in their reports concerning how much the shot hurt or how much they cried. In Phase 2, the same children were visited approximately 1 year after their inoculation. During 3 separate visits, they were either given additional pain-denying or neutral feedback. They were also given misleading or nonmisleading information about the actions of the pediatrician and the assistant. Children given pain-denying feedback reported that they cried less and that the shot hurt less than did children given neutral feedback. Those who were given misleading information about the actions of the assistant and the pediatrician made more false allegations about their actions than did children who were not given this information. These results challenge the view that suggestibility effects are confined to peripheral, nonaction events; in this study children's reports about salient actions involving their own bodies in stressful conditions were influenced.

The effect of local massage on adverse reactions and immunogenicity of diphtheria-tetanus-pertussis vaccine was investigated. After diphtheria-tetanus-pertussis vaccination 327 infants were either massaged or not, and adverse reactions were evaluated. Local pain and fever were more frequent in the massage group. The extra febrile episodes from massage were mild (38-39 degrees C). For evaluation of the antibody responses, 124 infants were recruited into massage or nonmassage cohorts and antibody production was measured at 2, 6, 7, 18 and 19 months of age, respectively. Subjects in the massage group developed significantly higher antibodies against filamentous hemagglutinin at 6 and 7 months of age, pertussis toxin at 6, 7, 18 and 19 months of age, pertussis agglutinogen at 18 and 19 months of age and those in the nonmassage group. Local massage after diphtheria-tetanus-pertussis vaccination was associated with better immunogenicity and more adverse reactions, including low grade fever and local pain, which were mild and not particularly disturbing.

In human newborns, small amounts of sucrose reduce crying with procedural pain by about 50%. To determine whether "sucrose analgesia" could be extended to painful procedures beyond the newborn period, 57 infants were randomly assigned to receive three 250-microliters doses of 50% sucrose solution (g/100 mL) or water before their diphtheria-tetanus-pertussis immunizations at 2 and 4 months of age. Crying during and after injection was measured separately to determine whether sucrose modified crying during the noxious stimulus, recovery from the stimulus, or both. Sucrose was effective in reducing crying only from 83 to 69%, and the reduction was limited to the postinjection period. We conclude that, although sucrose continues to have some effect beyond the newborn period, the effect is limited to recovery from the noxious stimulus, is clinically modest, and is probably smaller than in the newborn period.
