Daptacel® is a vaccine indicated for active immunization against diphtheria, tetanus and pertussis as a five-dose series in infants and children 6 weeks through 6 years of age (prior to seventh birthday).
2. DOSAGE AND ADMINISTRATION
. Immunization Series
Daptacel vaccine is to be administered as a 5 dose series at 2, 4 and 6 months of age (at intervals of 6-8 weeks), at 15-20 months of age and at 4-6 years of age. The first dose may be given as early as 6 weeks of age. Four doses of Daptacel vaccine constitute a primary immunization course for pertussis. The fifth dose is a booster for pertussis immunization. Three doses of Daptacel vaccine constitute a primary immunization course for diphtheria and tetanus. The fourth and fifth doses are boosters for diphtheria and tetanus immunization. [See Clinical Studies (14.1, 14.2, 14.3).]
Data are not available on the safety and immunogenicity of using mixed sequences of Daptacel vaccine and DTaP vaccines from different manufacturers for successive doses of the DTaP vaccination series. Daptacel vaccine may be used to complete the immunization series in infants who have received 1 or more doses of whole-cell pertussis DTP. However, the safety and efficacy of Daptacel vaccine in such infants have not been fully demonstrated.
If a decision is made to withhold any recommended dose of pertussis vaccine, [see Contraindications (4.2), (4.3) and Warnings and Precautions (5.2)], Diphtheria and Tetanus Toxoids Adsorbed For Pediatric Use (DT) should be administered.
Just before use, shake the vial well, until a uniform, white, cloudy suspension results. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. If these conditions exist, the product should not be administered.
When withdrawing a dose from a rubber-stoppered vial, do not remove either the rubber stopper or the metal seal holding it in place.
Each 0.5 mL dose of Daptacel vaccine is to be administered intramuscularly. In infants younger than 1 year, the anterolateral aspect of the thigh provides the largest muscle and is the preferred site of injection. In older children, the deltoid muscle is usually large enough for injection. The vaccine should not be injected into the gluteal area or areas where there may be a major nerve trunk.
Do not administer this product intravenously or subcutaneously.
Daptacel vaccine should not be combined through reconstitution or mixed with any other vaccine.
3. DOSAGE FORMS AND STRENGTHS
Daptacel vaccine is a suspension for injection in 0.5 mL single dose vials. See Description (11) for a complete listing of ingredients.
A severe allergic reaction (eg, anaphylaxis) after a previous dose of Daptacel vaccine or any other tetanus toxoid, diphtheria toxoid, or pertussis-containing vaccine, or any other component of this vaccine is a contraindication to administration of Daptacel vaccine. [See Description (11).] Because of uncertainty as to which component of the vaccine may be responsible, none of the components should be administered. Alternatively, such individuals may be referred to an allergist for evaluation if further immunizations are to be considered.
Encephalopathy (eg, coma, decreased level of consciousness, prolonged seizures) within 7 days of a previous dose of a pertussis containing vaccine that is not attributable to another identifiable cause is a contraindication to administration of any pertussis-containing vaccine (1), including Daptacel vaccine.
. Progressive Neurologic Disorder
Progressive neurologic disorder, including infantile spasms, uncontrolled epilepsy, or progressive encephalopathy is a contraindication to administration of any pertussis-containing vaccine (1) including Daptacel vaccine. Pertussis vaccine should not be administered to individuals with such conditions until a treatment regimen has been established and the condition has stabilized. (1)
5. WARNINGS AND PRECAUTIONS
. Management of Acute Allergic Reactions
Epinephrine hydrochloride solution (1:1,000) and other appropriate agents and equipment must be available for immediate use in case an anaphylactic or acute hypersensitivity reaction occurs.
. Adverse Reactions Following Prior Pertussis Vaccination
If any of the following events occur within the specified period after administration of a whole-cell pertussis vaccine or a vaccine containing an acellular pertussis component, the decision to administer Daptacel vaccine should be based on careful consideration of potential benefits and possible risks. (1) [See Dosage and Administration (2.1).]
- Temperature of ≥40.5°C (105°F) within 48 hours, not attributable to another identifiable cause.
- Collapse or shock-like state (hypotonic-hyporesponsive episode (HHE)) within 48 hours.
- Persistent, inconsolable crying lasting ≥3 hours within 48 hours.
- Seizures with or without fever within 3 days.
. Guillain-Barré Syndrome and Brachial Neuritis
A review by the Institute of Medicine found evidence for a causal relation between tetanus toxoid and both brachial neuritis and Guillain-Barré syndrome. (2) If Guillain-Barré syndrome occurred within 6 weeks of receipt of prior vaccine containing tetanus toxoid, the decision to give Daptacel vaccine or any vaccine containing tetanus toxoid should be based on careful consideration of the potential benefits and possible risks. (1)
. Infants and Children with a History of Previous Seizures
For infants or children with a history of previous seizures, an appropriate antipyretic may be administered (in the dosage recommended in its prescribing information) at the time of vaccination with a vaccine containing an acellular pertussis component (including Daptacel vaccine) and for the following 24 hours, to reduce the possibility of post-vaccination fever. (1)
. Limitations of Vaccine Effectiveness
Vaccination with Daptacel vaccine may not protect all individuals.
. Altered Immunocompetence
If Daptacel vaccine is administered to immunocompromised persons, including persons receiving immunosuppressive therapy, the expected immune response may not be obtained. [See Immunosuppressive Treatments (7.2).]
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a vaccine cannot be directly compared to rates in the clinical trials of another vaccine and may not reflect the rates observed in practice. The adverse reaction information from clinical trials does, however, provide a basis for identifying the adverse events that appear to be related to vaccine use and for approximating rates of those events.
A total of 17,577 doses of Daptacel vaccine have been administered to infants and children in 8 clinical studies. In all, 4,998 children received 3 doses of Daptacel vaccine, 1,725 of these children received 4 doses of Daptacel vaccine, and 485 of these children received 5 doses of Daptacel vaccine.
In a randomized, double-blinded pertussis vaccine efficacy trial, the Sweden I Efficacy Trial, conducted in Sweden during 1992-1995, the safety of Daptacel vaccine was compared with DT and a whole-cell pertussis DTP vaccine. A standard diary card was kept for 14 days after each dose and follow-up telephone calls were made 1 and 14 days after each injection. Telephone calls were made monthly to monitor the occurrence of severe events and/or hospitalizations for the 2 months after the last injection. There were fewer of the solicited common local and systemic reactions following Daptacel vaccine than following the whole-cell pertussis DTP vaccine. As shown in Table 1, the 2,587 infants who received Daptacel vaccine at 2, 4 and 6 months of age had similar rates of reactions within 24 hours as recipients of DT and significantly lower rates than infants receiving whole-cell pertussis DTP.

In the Sweden I Efficacy Trial, one case of whole limb swelling and generalized symptoms, with resolution within 24 hours, was observed following dose 2 of Daptacel vaccine. No episodes of anaphylaxis or encephalopathy were observed. No seizures were reported within 3 days of vaccination with Daptacel vaccine. Over the entire study period, 6 seizures were reported in the Daptacel vaccine group, 9 in the DT group and 3 in the whole-cell pertussis DTP group, for overall rates of 2.3, 3.5 and 1.4 per 1,000 vaccinees, respectively. One case of infantile spasms was reported in the Daptacel vaccine group. There were no instances of invasive bacterial infection or death.
In a US study, children received 4 doses of Daptacel vaccine at 2, 4, 6 and 15-17 months of age. A total of 1,454 children received Daptacel vaccine and were included in the safety analyses. Of these, 51.7% were female, 77.2% Caucasian, 6.3% Black, 6.5% Hispanic, 0.9% Asian and 9.1% other races. In a subsequent study, a non-random subset of 485 of these children received a fifth dose of Daptacel vaccine at 4-6 years of age. The children included in the fifth dose study were representative of all children who received four doses of Daptacel vaccine in the earlier study with regard to frequencies of solicited local and systemic adverse events following the fourth dose. At 2, 4 and 6 months of age, Daptacel vaccine was administered concomitantly with Haemophilus influenzae type b (Hib) conjugate vaccine (tetanus toxoid conjugate) (Sanofi Pasteur SA), inactivated poliovirus vaccine (IPV) (Sanofi Pasteur SA), and 7-valent pneumococcal conjugate vaccine (Wyeth Pharmaceuticals Inc.). Infants had received the first dose of hepatitis B vaccine at 0 months of age. At 2 and 6 months of age, hepatitis B vaccine (recombinant) (Merck & Co., Inc.) was also administered concomitantly with Daptacel vaccine. Based on random assignment, the fourth dose of Daptacel vaccine was administered either alone; concomitantly with Hib conjugate (tetanus toxoid conjugate) vaccine; or concomitantly with Hib conjugate (tetanus toxoid conjugate) vaccine, 7-valent pneumococcal conjugate vaccine, measles, mumps, rubella (MMR) vaccine (Merck & Co., Inc.), and varicella vaccine (Merck & Co., Inc.). The fifth dose of Daptacel vaccine was administered concomitantly with IPV and MMR vaccine.
In the US studies, the occurrence of solicited local and systemic adverse events listed in Table 3 was recorded daily by parents or guardians for Days 0-7 following vaccination. For Days 0 and 1 following the first three doses of Daptacel vaccine, signs and symptoms of HHE also were solicited. Periodic telephone calls were made to inquire about adverse events. Serious adverse events were monitored during the two studies, through 6 months following the fourth and fifth doses of Daptacel vaccine, respectively.
The incidence and severity of selected solicited local and systemic adverse events that occurred within 3 days following each dose of Daptacel vaccine are shown in Table 3. The incidence of redness, tenderness and swelling at the Daptacel injection site increased with the fourth and fifth doses, with the highest rates reported after the fifth dose.

In the US study in which children received 4 doses of Daptacel vaccine, of 1,454 subjects who received Daptacel vaccine, 5 (0.3%) subjects experienced a seizure within 60 days following any dose of Daptacel vaccine. One seizure occurred within 7 days post-vaccination: an infant who experienced an afebrile seizure with apnea on the day of the first vaccination. Three other cases of seizures occurred between 8 and 30 days post-vaccination. Of the seizures that occurred within 60 days post-vaccination, 3 were associated with fever. In this study, there were no reported cases of HHE following Daptacel vaccine. There was one death due to aspiration 222 days post-vaccination in a subject with ependymoma. Within 30 days following any dose of Daptacel vaccine, 57 (3.9%) subjects reported at least one serious adverse event. During this period, the most frequently reported serious adverse event was bronchiolitis, reported in 28 (1.9%) subjects. Other serious adverse events that occurred within 30 days following Daptacel vaccine include three cases of pneumonia, two cases of meningitis and one case each of sepsis, pertussis (post-dose 1), irritability and unresponsiveness.
In the 5th dose study of Daptacel vaccine in the US, within 30 days following the 5th consecutive dose of Daptacel vaccine, 1 (0.2%) subject reported 2 serious adverse events (bronchospasm and hypoxia).
In another study (Sweden II Efficacy Trial), 3 DTaP vaccines and a whole-cell pertussis DTP vaccine, none of which are licensed in the US, were evaluated to assess relative safety and efficacy. This study included HCPDT, a vaccine made of the same components as Daptacel vaccine but containing twice the amount of detoxified PT and four times the amount of FHA (20 μg detoxified PT and 20 μg FHA). HHE was observed following 29 (0.047%) of 61,220 doses of HCPDT; 16 (0.026%) of 61,219 doses of an acellular pertussis vaccine made by another manufacturer; and 34 (0.056%) of 60,792 doses of a whole-cell pertussis DTP vaccine. There were 4 additional cases of HHE in other studies using HCPDT vaccine for an overall rate of 33 (0.047%) in 69,525 doses.
. Data from Post-Marketing Experience
The following adverse events have been spontaneously reported during the post-marketing use of Daptacel vaccine in the US and other countries. Because these events are reported voluntarily from a population of uncertain size, it may not be possible to reliably estimate their frequency or establish a causal relationship to vaccine exposure.
The following adverse events were included based on one or more of the following factors: severity, frequency of reporting, or strength of evidence for a causal relationship to Daptacel vaccine.
- Cardiac disorders
- Gastro-intestinal disorders
- General disorders and administration site conditions
Local reactions: injection site pain, injection site rash, injection site nodule, injection site mass, extensive swelling of injected limb (including swelling that involves adjacent joints).
- Infections and infestations
Injection site cellulitis, cellulitis, injection site abscess
- Immune system disorders
Hypersensitivity, allergic reaction, anaphylactic reaction (edema, face edema, swelling face, pruritus, rash generalized) and other types of rash (erythematous, macular, maculo-papular)
- Nervous system disorders
Convulsions: febrile convulsion, grand mal convulsion, partial seizures
HHE, hypotonia, somnolence
- Psychiatric disorders
7. DRUG INTERACTIONS
. Concomitant Administration with Other Vaccines
In clinical trials, Daptacel vaccine was administered concomitantly with one or more of the following US licensed vaccines: Hib conjugate vaccine, IPV, hepatitis B vaccine, pneumococcal conjugate vaccine, MMR vaccine, and varicella vaccine. [See Adverse Reactions (6.1) and Clinical Studies (14).] When Daptacel vaccine is given at the same time as another injectable vaccine(s), the vaccine should be administered with different syringes.
. Immunosuppressive Treatments
Immunosuppressive therapies, including irradiation, antimetabolites, alkylating agents, cytotoxic drugs and corticosteroids (used in greater than physiologic doses), may reduce the immune response to Daptacel vaccine.
8. USE IN SPECIFIC POPULATIONS
Pregnancy Category C
Animal reproduction studies have not been conducted with Daptacel vaccine. It is also not known whether Daptacel vaccine can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity.
. Pediatric Use
Daptacel vaccine is not indicated for infants below 6 weeks of age or children 7 years of age or older. Safety and effectiveness of Daptacel vaccine in these age groups have not been established.
Daptacel vaccine is a sterile isotonic suspension of pertussis antigens and diphtheria and tetanus toxoids adsorbed on aluminum phosphate, for intramuscular injection.
Each 0.5 mL dose contains 15 Lf diphtheria toxoid, 5 Lf tetanus toxoid and acellular pertussis antigens [10 µg detoxified pertussis toxin (PT), 5 µg filamentous hemagglutinin (FHA), 3 µg pertactin (PRN), and 5 µg fimbriae types 2 and 3 (FIM)].
Other ingredients per 0.5 mL dose include 1.5 mg aluminum phosphate (0.33 mg of aluminum) as the adjuvant, ≤5 µg residual formaldehyde, <50 ng residual glutaraldehyde and 3.3 mg (0.6% v/v) 2-phenoxyethanol (not as a preservative).
The acellular pertussis vaccine components are produced from Bordetella pertussis cultures grown in Stainer-Scholte medium (3) modified by the addition of casamino acids and dimethyl-beta-cyclodextrin. PT, FHA and PRN are isolated separately from the supernatant culture medium. The FIM components are extracted and co-purified from the bacterial cells. The pertussis antigens are purified by sequential filtration, salt-precipitation, ultrafiltration and chromatography. PT is detoxified with glutaraldehyde. FHA is treated with formaldehyde, and the residual aldehydes are removed by ultrafiltration. The individual antigens are adsorbed separately onto aluminum phosphate.
Corynebacterium diphtheriae is grown in modified Mueller's growth medium. (4) After purification by ammonium sulfate fractionation, diphtheria toxin is detoxified with formaldehyde and diafiltered. Clostridium tetani is grown in modified Mueller-Miller casamino acid medium without beef heart infusion. (5) Tetanus toxin is detoxified with formaldehyde and purified by ammonium sulfate fractionation and diafiltration. Diphtheria and tetanus toxoids are individually adsorbed onto aluminum phosphate.
The adsorbed diphtheria, tetanus and acellular pertussis components are combined with aluminum phosphate (as adjuvant), 2-phenoxyethanol (not as a preservative) and water for injection.
Both diphtheria and tetanus toxoids induce at least 2 units of antitoxin per mL in the guinea pig potency test. The potency of the acellular pertussis vaccine components is determined by the antibody response of immunized mice to detoxified PT, FHA, PRN and FIM as measured by enzyme-linked immunosorbent assay (ELISA).
12. CLINICAL PHARMACOLOGY
. Mechanism of Action
Diphtheria is an acute toxin-mediated disease caused by toxigenic strains of C diphtheriae. Protection against disease is due to the development of neutralizing antibodies to diphtheria toxin. A serum diphtheria antitoxin level of 0.01 IU/mL is the lowest level giving some degree of protection. Antitoxin levels of at least 0.1 IU/mL are generally regarded as protective. (6) Levels of 1.0 IU/mL have been associated with long-term protection. (7)
Tetanus is an acute disease caused by an extremely potent neurotoxin produced by C tetani. Protection against disease is due to the development of neutralizing antibodies to tetanus toxin. A serum tetanus antitoxin level of at least 0.01 IU/mL, measured by neutralization assay is considered the minimum protective level. (6) (8) A tetanus antitoxin level ≥0.1 IU/mL as measured by the ELISA used in clinical studies of Daptacel vaccine is considered protective.
Pertussis (whooping cough) is a respiratory disease caused by B pertussis. This Gram-negative coccobacillus produces a variety of biologically active components, though their role in either the pathogenesis of, or immunity to, pertussis has not been clearly defined.
13. NON-CLINICAL TOXICOLOGY
. Carcinogenesis, Mutagenesis, Impairment of Fertility
Daptacel vaccine has not been evaluated for carcinogenic or mutagenic potential or impairment of fertility.
14. CLINICAL STUDIES
In a US study in which children received 4 doses of Daptacel vaccine at 2, 4, 6 and 15-17 months of age, after the third dose, 100% (N = 1,099) achieved diphtheria antitoxin levels of ≥0.01 IU/mL and 98.5% achieved diphtheria antitoxin levels of ≥0.10 IU/mL. Among a random subset of children who received the fourth dose of Daptacel vaccine at 15-16 months of age, 96.5% (N = 659) achieved diphtheria antitoxin levels of ≥1.0 IU/mL after the fourth dose.
In a US study in which children received 4 doses of Daptacel vaccine at 2, 4, 6 and 15-17 months of age, after the third dose, 100% (N = 1,037) achieved tetanus antitoxin levels of ≥0.10 IU/mL. Among a random subset of children who received the fourth dose of Daptacel vaccine at 15-16 months of age, 98.8% (N = 681) achieved tetanus antitoxin levels of ≥1.0 IU/mL after the fourth dose.
A randomized, double-blinded, placebo-controlled efficacy and safety study was conducted in Sweden during 1992-1995 (Sweden I Efficacy Trial) under the sponsorship of the National Institute of Allergy and Infectious Diseases. A total of 9,829 infants received 1 of 4 vaccines: Daptacel vaccine (N = 2,587); another investigational acellular pertussis vaccine (N = 2,566); whole-cell pertussis DTP vaccine (N = 2,102); or DT vaccine as placebo (Swedish National Bacteriological Laboratory, N = 2,574). Infants were immunized at 2, 4 and 6 months of age. The mean length of follow-up was 2 years after the third dose of vaccine. The protective efficacy of Daptacel vaccine against pertussis after 3 doses using the World Health Organization (WHO) case definition (≥21 consecutive days of paroxysmal cough with culture or serologic confirmation or epidemiologic link to a confirmed case) was 84.9% (95% confidence interval [CI] 80.1 to 88.6). The protective efficacy of Daptacel vaccine against mild pertussis (≥1 day of cough with laboratory confirmation) was 77.9% (95% CI 72.6 to 82.2). Protection against pertussis by Daptacel vaccine was sustained for the 2-year follow-up period.
In order to assess the antibody response to the pertussis antigens of Daptacel vaccine in the US population, 2 lots of Daptacel vaccine, including the lot used in the Sweden I Efficacy Trial, were administered to US infants in the US Bridging Study. In this study, antibody responses following 3 doses of Daptacel vaccine given to US children at 2, 4 and 6 months of age were compared to those from a subset of the infants enrolled in the Sweden I Efficacy Trial. Assays were performed in parallel on the available sera from the US and Swedish infants. Antibody responses to all the antigens were similar except for those to the PRN component. For both lots of Daptacel vaccine, the geometric mean concentration (GMC) and percent response to PRN in US infants (Lot 006, N = 107; Lot 009, N = 108) were significantly lower after 3 doses of vaccine than in Swedish infants (N = 83). In separate US and Canadian studies in which children received Daptacel vaccine at 2, 4 and 6 months of age, with a fourth dose at either 17-20 months (Canadian study) or 15-16 months (random subset from US study) of age, antibody responses to each pertussis antigen following the fourth dose (Canadian study N = 275; US study N = 237-347) were at least as high as those seen in the Swedish infants after 3 doses. While a serologic correlate of protection for pertussis has not been established, the antibody response to all antigens in North American infants after 4 doses of Daptacel vaccine at 2, 4, 6 and 15-20 months of age was comparable to that achieved in Swedish infants in whom efficacy was demonstrated after 3 doses of Daptacel vaccine at 2, 4 and 6 months of age.
. Concomitantly Administered Vaccines
In the US Bridging study, Daptacel vaccine was given concomitantly with Hib conjugate vaccine (Sanofi Pasteur SA) according to local practices. Anti-PRP immune response was evaluated in 261 infants who received 3 doses of Hib conjugate vaccine. One month after the third dose, 96.9% achieved anti-PRP antibody levels of at least 0.15 µg/mL and 82.7% achieved antibody levels of at least 1.0 µg/mL.
In the US study in which infants received Daptacel vaccine concomitantly with Hib conjugate (tetanus toxoid conjugate) vaccine, IPV, 7-valent pneumococcal conjugate vaccine, and hepatitis B vaccine [see Adverse Reactions (6.1)], at 7 months of age, 100.0% of subjects (N = 1,050-1,097) had protective neutralizing antibody levels (≥1:8 1/dil) for poliovirus types 1, 2 and 3; and 92.4% (N = 998) achieved anti-hepatitis B surface antigen levels ≥10.0 mIU/mL. Although there is no established serologic correlate of protection for any of the pneumococcal serotypes, at 7 months of age 91.3%-98.9% (N = 1,027-1,029) achieved anti-pneumococcal polysaccharide levels ≥0.5 µg/mL for serotypes 4, 9V, 14, 18C, 19F and 23F and 80.7% (N = 1,027) achieved an anti-pneumococcal polysaccharide level ≥0.5 µg/mL for serotype 6B. The mumps seroresponse rate was lower when Daptacel vaccine was administered concomitantly (86.6%; N = 307) vs. non-concomitantly (90.1%; N = 312) with the first dose of MMR vaccine [upper limit of 90% confidence interval for difference in rates (non-concomitant minus concomitant) >5%]. There was no evidence for interference in the immune response to the measles, rubella, and varicella antigens or to the fourth dose of the 7-valent pneumococcal conjugate vaccine with concomitant administration of Daptacel vaccine.
