Tripedia Side Effects Center

Medical Editor: John P. Cunha, DO, FACOEP

Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) (DTaP) is a vaccine used to prevent diphtheria, tetanus (lockjaw), and pertussis (whooping cough). It is an immunization. Common side effects include mild fever, redness, pain, tenderness, or swelling where the shot was given, fussiness for 1-3 days after the shot, tiredness or poor appetite for 1-3 days after the shot, or vomiting for 1-3 days after the shot.

A 0.5 mL dose of Tripedia vaccine is given to infants and children 6 weeks to 7 years of age (prior to seventh birthday) as a five-dose series. The series consists of a primary immunization course of three doses administered at 2, 4, and 6 months of age, followed by two booster doses, recommended at 15 to 18 months of age, and at 4 to 6 years of age, respectively. Consult your doctor for the immunization schedule. Tripedia may interact with steroids, cancer chemotherapy or radiation, azathioprine, basiliximab, cyclosporine, etanercept, leflunomide, muromonab-CD3, mycophenolate mofetil, sirolimus, or tacrolimus. Tell your doctor all medications and supplements you use. Tripedia may be harmful to a fetus and should not be given to a pregnant woman. Consult your doctor before breastfeeding.

Our Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

Tripedia in Detail - Patient Information: Side Effects

Keep track of any and all side effects your child has after receiving this vaccine. When the child receives the next booster dose, you will need to tell the doctor if the first shot caused any side effects. Getting diphtheria, tetanus, or pertussis disease is much riskier than getting DTaP vaccine. However, like any medicine, this vaccine, can cause side effects. The risk of DTaP vaccine causing a serious side effect is extremely small.

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if the child has any of the following serious side effects:

  • loss of consciousness;
  • seizure (black-out or convulsions);
  • high fever, over 105 degrees; or
  • non-stop crying for 3 hours or more.

Other less serious side effects may be more likely to occur. Talk to your doctor if your child has:

  • mild fever;
  • redness, pain, tenderness, or swelling where the shot was given;
  • fussiness for 1-3 days after the shot;
  • tiredness or poor appetite for 1-3 days after the shot; or
  • vomiting for 1-3 days after the shot.

Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.

To help reduce fever and pain, your doctor may recommend giving the child an aspirin-free pain reliever such as acetaminophen (Tylenol, Tempra, others) or ibuprofen (Motrin, Advil). This may be given at the time of the shot and over the next 24 hours. Your doctor will tell you the correct dose to use. Controlling fever is especially important if the child has a history of seizures.

(Adverse Reactions)

SIDE EFFECTS

Over 3, 000 US and 12, 000 German infants received one or more doses of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine as part of the primary immunization series in clinical trials conducted by the sponsor and the National Institutes of Health (NIH). A subset of over 1, 000 German and US children were monitored for adverse events through a fourth successive dose of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine. A subset of 580 German children were monitored for adverse events through a fifth successive dose of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine.

Over 400 children who had received three doses of whole-cell pertussis DTP vaccine were assessed for adverse events following a booster dose of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine at 15 to 20 months of age.

In a double-blind, comparative US trial, 673 infants were randomized to receive either 3 doses of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine or AvPs whole-cell pertussis DTP vaccine (Table 2).2 Safety data are available for 672 infants, including 505 who received Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine and 167 who received whole-cell pertussis DTP vaccine. Following all three doses, rates for all reported local reactions, fever > 101°F, irritability, drowsiness, and anorexia were significantly less in Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine recipients. Reaction rates generally peaked within the first 24 hours, and decreased substantially over the next two days.2,27,28

† For certain adverse events information was not available for a small number of infants.

Adverse event data for Tables 2-9 were actively collected using patient diaries, phone call follow-up, and/or by questioning the parent(s) at clinic visits. All data were recorded on standardized case report forms.

A similar reduction in adverse events was seen in a randomized, double-blind, comparative trial conducted in the US by the NIH when Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine was compared to Lederle Laboratories whole-cell pertussis DTP vaccine (Table 3).29 Each data point presented in Table 3 is a summary of the frequency of reactions following any of the three primary immunizing doses. Local adverse reactions, which include pain, erythema, swelling, and systemic reactions such as fever, anorexia, vomiting, drowsiness and fussiness may have occurred following any of the three primary vaccinations.

In a multicenter trial conducted by the NIH in the US, the frequency of adverse reactions following each dose in children who received only Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine is shown in Table 4.2,29-31 Of the 135 infants who received Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine at 2, 4, and 6 months of age, a subset of 82 received a fourth dose of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine and a subset of 18 received a fifth dose of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine. A trend towards an increased frequency of redness and swelling was noted with successive doses.

A subset of children who participated in a German vaccine efficacy study were vaccinated with a fourth consecutive dose of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine in the study I92-2923-01 (Table 5). Data on the frequency of local and systemic reactions for 72 hours following vaccination was obtained from a diary provided to the parents at the time of vaccination and returned to the investigator by mail.

The frequency of adverse events following a fifth consecutive dose of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine administered to German children 4 to 6 years of age is shown in Table 7. This fifth dose study was an open label study that enrolled 580 subjects from 24 sites. These subjects were recruited from subjects who had participated in the case-control study of the efficacy of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine in which more than 12, 000 infants received three doses of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine. In the fifth dose study, information on systemic and local reactions was collected on diary forms for 3 days following vaccination for all subjects, and for 14 days following vaccination for a subset of 241 subjects. For 490 subjects, the actual sizes of local reactions > 5 cm, as measured by the parents, was also documented on the diary forms. Local reactions, including those measured as ≥11 cm, typically had an onset within the first three days after vaccination and generally resolved within five days. Three subjects had a local reaction that lasted more than 21 days one subject had swelling for 25 days, one subject had redness for 26 days, and one subject had redness for 28 days. Twenty-eight (4.8%) of 580 subjects had redness and/or swelling that led to a medical visit. There were no reported permanent sequelae associated with any local reactions. Thirty-two of 490 subjects (6.5%) had swelling reported as ≥11 cm, including 14 subjects (2.9%) who reported swelling of the entire upper arm. Swelling of the entire upper arm was not specifically solicited. Of 32 subjects with swelling reported as ≥11 cm, 19 also reported pain, 30 had redness and 2 had fever > 38°C. All cases of swelling ≥11 cm resolved spontaneously without treatment, except for a few subjects who were treated with cool packs. The subjects in the fifth dose study are not necessarily a subset of the 1, 010 German children for whom safety data following the fourth dose of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine are available (Table 5). However, children in both the fourth and fifth dose studies were recruited from subjects who had participated in the German case-control study. Available data from these studies suggest an increased frequency and severity of local reactions following the fifth successive dose of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine compared with the fourth dose.2 Additional safety data in 96 US children who received a fifth dose of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine following four previous doses of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine or Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine combined with ActHIB vaccine (TriHIBit vaccine) also demonstrated an increase in the frequency and severity of local reactions following the fifth dose compared with the first three doses.2

When Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine was used to reconstitute ActHIB vaccine (TriHIBit vaccine) and administered to children 15 to 20 months of age who had received 3 prior doses of whole-cell pertussis DTP vaccine, the systemic adverse experience profile was comparable to that observed when the two vaccines were given separately. An increase in rates of minor local reactions was observed within the 24-hour period after immunization when compared to the Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine and ActHIB vaccine administered separately. However, local adverse event rates of the combined vaccines were comparable when taking into consideration reactions observed at the ActHIB vaccine site.2 (Refer to ActHIB vaccine package insert.)

The results of an open label, non-controlled clinical study, of 2, 457 US children targeted to evaluate less common and more severe adverse events following three doses of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine in the primary series are shown in Table 9. Data were collected by parental interview at subsequent immunization visits, chart review and telephone calls to the parents 60 days after the third dose.

In the German case control efficacy study that enrolled 16, 780 infants, 12, 514 of whom received 41, 615 doses of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine, hospitalization rates and death rates were similar between Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine and DT vaccine recipients. Adverse events were monitored by spontaneous reporting by parents and a medical history obtained at each subsequent vaccination. Adverse events (rates per 1, 000 doses) occurring within 7 days following vaccination with Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine included: unusual cry (0.96), persistent cry > 3 hours (0.12), febrile seizure (0.05), afebrile seizure (0.02) and hypotonic/hyporesponsive episodes (0.05).2

In the Swedish efficacy trial where 1, 419 recipients received the pertussis components in Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine, three deaths due to invasive bacterial infections occurred. Further investigation revealed no evidence for a causal relation between vaccination and altered resistance to invasive disease caused by encapsulated bacteria.33 While the hypothesis that the two variables are related cannot be ruled out in the Swedish trial, deaths due to invasive bacterial infections have been monitored in other trials. In contrast to the Swedish trial, in the German case-control study and US open-label safety study, 14, 971 infants received Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine and no deaths due to invasive bacterial infections were reported.

In the German case-control study and US open-label safety study in which 14, 971 infants received Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine, 13 deaths in Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine recipients were reported. Causes of deaths included seven SIDS, and one of each of the following: enteritis, Leigh Syndrome, adrenogenital syndrome, cardiac arrest, motor vehicle accident, and accidental drowning. All of these events occurred more than two weeks past immunization.2 The rate of SIDS observed in the German case-control study was 0.4/1, 000 vaccinated infants. The rate of SIDS observed in the US open-label safety study was 0.8/1, 000 vaccinated infants and the reported rate of SIDS in the US from 1985-1991 was 1.5/1, 000 live births.34 By chance alone, some cases of SIDS can be expected to follow receipt of whole-cell pertussis DTP35 or DTaP vaccines.

Additional Adverse Reactions:

· As with other aluminum-containing vaccines, a nodule may be palpable at the injection sites for several weeks. Sterile abscess formation at the site of injection has been reported.3,36

· Rarely, an anaphylactic reaction (ie, hives, swelling of the mouth, difficulty breathing, hypotension, or shock) has been reported after receiving preparations containing diphtheria, tetanus, and/or pertussis antigens.3

· Arthus-type hypersensitivity reactions, characterized by severe local reactions (generally starting 2-8 hours after an injection), may follow receipt of tetanus toxoid.

· A few cases of peripheral mononeuropathy and of cranial mononeuropathy have been reported following tetanus toxoid administration, although available evidence is inadequate to accept or reject a causal relation.37

· A review by the Institute of Medicine (IOM) found evidence for a causal relationship between tetanus toxoid and both brachial neuritis and Guillain-Barré syndrome.37

· A few cases of demyelinating diseases of the CNS have been reported following some tetanus toxoid-containing vaccines or tetanus and diphtheria toxoid-containing vaccines, although the IOM concluded that the evidence was inadequate to accept or reject a causal relationship.37

Adverse events reported during post-approval use of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine include idiopathic thrombocytopenic purpura, SIDS, anaphylactic reaction, cellulitis, autism, convulsion/grand mal convulsion, encephalopathy, hypotonia, neuropathy, somnolence and apnea. Events were included in this list because of the seriousness or frequency of reporting. Because these events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequencies or to establish a causal relationship to components of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine.2

Reporting of Adverse Events

The National Vaccine Injury Compensation Program, established by the National Childhood Vaccine Injury Act of 1986, requires physicians and other health-care providers who administer vaccines to maintain permanent vaccination records of the manufacturer and lot number of the vaccine administered in the vaccine recipients permanent medical record along with the date of administration of the vaccine and the name, address and title of the person administering the vaccine. The Act (or statute) further requires the health-care professional to report to the Secretary of the US Department of Health and Human Services the occurrence following immunization of any events set forth in the statute or the Vaccine Injury Table, including anaphylaxis or anaphylactic shock within 7 days; encephalopathy or encephalitis within 7 days, brachial neuritis within 28 days; or an acute complication or sequelae (including death) of an illness, disability, injury, or condition referred to above, or any events that would contraindicate further doses of vaccine, according to this Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) vaccine package insert.38,39

Reporting by parents or guardians of all adverse events after vaccine administration should be encouraged.
