Your goal is to extract structured information from the user's input that matches the form described below. When extracting information please make sure it matches the type information exactly. Do not add any attributes that do not appear in the schema shown below.

```TypeScript

 { // Information on the clinical trial characteristics from the abstract
 conditions: string // The condition or disease being treated in the clinical trial
 drug_or_intervention: string // The drug or intervention used in the clinical trial
}
```


Please output the extracted information in JSON format. Do not output anything except for the extracted information. Do not add any clarifying information. Do not add any fields that are not in the schema. If the text contains attributes that do not appear in the schema, please ignore them. All output must be in JSON format and follow the schema specified above. Wrap the JSON in <json> tags.



Input:Repeated administration of a reduced-antigen-content diphtheria-tetanus-acellular pertussis and poliomyelitis vaccine (dTpa-IPV; Boostrix™ IPV).  The rising incidence of pertussis amongst adults and adolescents in industrialized countries could be reduced by replacing tetanus and diphtheria (Td) boosters with reduced-antigen-content dT-acellular pertussis (dTpa)vaccines. Repeated administration of a dTpa-IPV (dTpa-inactivated poliomyelitis; BoostrixTM Polio, GlaxoSmithKline)booster to adolescents, 5 years after their previous dose was evaluated. Before the second dTpa-IPV booster, the percentage of subjects who were seroprotected/seropositive was: 98.2% (D); 98.5% (T); 40.6% (PT); 99.7% (FHA); 97.0% (PRN); 98.8% (anti-polio 1); 99.7% (anti-polio 2); 97.0% (anti-polio 3). One month after the second dTpa-IPV dose, all subjects were seroprotected against D, T and polio and anti-pertussis booster responses (seroconversion or ≥2-fold increase) were seen in 93.3% (PT), 93.4% (FHA) and 95.2% (PRN) of subjects.During 4-day follow-up, 4.1% subjects recorded grade 3 pain; 4.6% and 3.6% recorded redness or swelling >50 mm, respectively. No serious adverse events were recorded. The incidence of symptoms was not higher than after the previous booster. 415 subjects (mean age 11.4 years) who had received either dTpa-IPV or dTpa + IPV at age 4–8 years, all received one dose of dTpa-IPV in this open, phase IV trial. Blood samples were taken before and one-month post-vaccination. Antibody concentrations against D, T, pertussis toxoid (PT), filamentous haemagglutinin (FHA), pertactin (PRN) and polio antigens were determined. Reactogenicity and safety was assessed. A second dTpa-IPV booster was highly immunogenic and well tolerated in this population of adolescents, supporting the repeated administration of BoostrixTM Polio.
