Tetanus and Diphtheria Toxoids Adsorbed Combined With Component Pertussis Vaccine-adolescents and adults aged 12 to 54 years.
Pharmacology: Immunization against tetanus, diphtheria, and pertussis has been associated with a striking decrease in the incidence of morbidity and mortality from these diseases. Simultaneous vaccination with combination vaccines containing diphtheria and tetanus toxoids and pertussis vaccine has been a cornerstone of the Canadian immunization programme.
Tetanus is an acute and often fatal disease caused by an extremely potent neurotoxin produced by C. tetani. The organism is ubiquitous and its occurrence in nature cannot be controlled. Immunization is highly effective, provides long-lasting protection, and is recommended for the whole population. Only 2 to 3 cases of tetanus are now reported annually in Canada. Tetanus toxoid is prepared by detoxification of tetanus toxin with formaldehyde.
Diphtheria is a serious communicable disease caused by toxigenic strains of C.diphtherias. The organism may be harbored in the nasopharynx, skin or other sites of asymptomatic carriers, making eradication of the disease difficult. Routine immunization against diphtheria in infancy and childhood has been widely practised in Canada since 1930, resulting in a decline in morbidity and mortality. Fewer than 5 cases are now reported annually in Canada. The case-fatality rate remains at 5 to 10%, with the highest death rates in the very young and elderly. The disease occurs most frequently in unimmunized or partially immunized individuals. Diphtheria toxoid is a cell-free preparation of diphtheria toxin detoxified with formaldehyde. The immunity conferred is antitoxic, not antibacterial, and thus protects against the potentially lethal systemic effects of diphtheria toxin but not directly against local infection.
Injection of bacterial proteins such as tetanus and diphtheria toxoids results in the production of protective antibodies. A primary series consisting of 2 or more injections is required to prime the immune system and produce a satisfactory protective antibody level. Tetanus antitoxin levels of >0.01 IU/mL are generally accepted as good evidence of immunity from tetanus. Diphtheria antitoxin levels of >0.01 IU/mL are thought to be the minimal level required for protection. Levels >0.05 lU/mL are considered optimal for protection. After completion of a primary series, circulating antibodies to tetanus and diphtheria toxoids gradually decline but are thought to persist at protective levels for up to 10 years. Tetanus and diphtheria toxoid boosters are recommended every 10 years.
Pertussis (whooping cough) is a highly communicable bacterial disease caused by B. pertussis. Severity and mortality are greatest in infancy, and even infants born to apparently immune mothers are highly susceptible to infection, particularly if maternal immunity was induced by whole-cell pertussis vaccine. The incidence of pertussis has declined by over 90% during the last 40 years, because of universal childhood immunization programs using whole-cell pertussis combination vaccines. However, due to the limited effectiveness observed with some whole-cell vaccines, and the greater likelihood of waning immunity with such vaccines, particularly in adolescents and adults, major outbreaks of pertussis continue to occur. Hospitalizations for pertussis are still common in Canada and several deaths from pertussis occur each year, particularly in unimmunized infants. Much of the resurgence of pertussis is related to the role played by susceptible adolescents and adults where pertussis is often unrecognized and is actually more common than realized. Adolescents and adults are in fact the main reservoir for pertussis infection in the general population and they act as the primary source of transmission to infants. While vaccination of this target group has been recognized as potentially useful adjunct for routine pertussis prevention and control measures, implementation has not been feasible with whole-cell pertussis vaccines. These were contraindicated in persons over the age of 7 years due to an unacceptably high rate of reactions.
Controversy regarding the safety of whole-cell pertussis vaccine during the 1970s led to several studies of the benefits and risks of this vaccination during the 1980s. The epidemiologic analyses clearly indicate that the benefits of a childhood pertussis immunization program outweigh the risks. Concerns about the safety of the whole-cell vaccines also accelerated research into potentially less reactogenic alternatives. Acellular pertussis vaccines consisting of purified fractions of the B. pertussis bacterium were used effectively to control pertussis in children 2 years of age or older in Japan since 1981. Acellular pertussis combination vaccines have subsequently been shown as being much less reactogenic than the whole-cell pertussis combinations.
A randomized controlled efficacy study was conducted in Sweden using Tripacel (Component Pertussis Vaccine Combined with Diphtheria and Tetanus Toxoids Adsorbed), which contains higher concentrations of PT and diphtheria toxoid than the adult formulation. In this study, 2551 infants received Tripacel and 2539 infants received a control vaccine containing diphtheria and tetanus toxoids at 2, 4 and 6 months of age. Tripacel demonstrated a clinical efficacy of 85.1% against pertussis disease (defined as 21 days of paroxysmal cough with culture or serologic confirmation of infection with B. pertussis).
Another formulation of Tripacel containing twice the quantity of PT and 4 times the quantity of FHA was used in the second phase of the Swedish Efficacy study involving over 20 000 children. This study confirmed that the 5-component vaccine was as effective as a UK whole cell pertussis vaccine, not only against severe pertussis (paroxysmal cough > 21 days), but against clinical pertussis illness regardless of duration of cough.
Clinical Trial Data: In a clinical trial involving 749 individuals ranging in age from 12 to 54 years who had not been immunized against tetanus, diphtheria, or pertussis within the previous 5 years, 449 received a single 0.5 mL dose of 1 of 3 clinical trial lots of Adacel. The remaining 300 received a dose of Td Adsorbed and of Component Pertussis (cP) Vaccine, given separately, 1 month apart. One hundred and fifty-one individuals received Td Adsorbed at visit 1 and cP Vaccine at visit 2 and 149 individuals received cP and Td in the reverse sequence.
Four weeks following the Adacel injection, of 446 individuals tested, 100% had tetanus antitoxin titres ≥ 0.10 lU/mL with a geometric mean titre of 15.7 lU/mL, while over 84% had diphtheria antitoxin litres ≥ 0.10 lU/mL (over 97% ≥ 0.01 IU/mL) with a geometric mean titre of 0.82 IU/mL. Pertussis antibody responses were comparable to those seen after a full 3-dose primary series with Tripacel (Component Pertussis Vaccine Combined with Diphtheria and Tetanus Toxoids Adsorbed), in infants (i.e., 2, 4, and 6 months of age), or after a fourth dose (18 months of age) of Pentacel (Haemophilus b Conjugate Vaccine [Tetanus Protein-Conjugate] reconstituted with Component Pertussis Vaccine and Diphtheria and Tetanus Toxoids Adsorbed Combined with Inactivated Poliomyelitis Vaccine)(see Table I).
Adverse events following Adacel were generally comparable to those seen with Td adsorbed (see Adverse Effects).

Indications: Prevention of tetanus, diphtheria and whooping cough in adolescents and adults aged 12 to 54 years. Human Immunodeficiency Virus (HIV)-lnfected Persons: HIV-infected individuals, both asymptomatic and symptomatic, should be immunized against diphtheria, pertussis and tetanus according to standard schedules.
Persons who have had tetanus or diphtheria should still be immunized since these clinical infections do not always confer immunity. Those who have had natural pertussis can continue to receive pertussis-containing vaccines.
Contraindications: General: Immunization with Adacel should be deferred in the presence of any acute illness, including febrile illness to avoid superimposing adverse effects from the vaccine on the underlying illness or mistakenly attributing to the vaccine a manifestation of the underlying illness. A minor afebrile illness such as mild upper respiratory infection is not usually a reason to defer immunization.
Absolute Contraindications: Allergy to any component of Adacel (see Supplied) or an anaphylactic or other allergic reaction to a previous dose of Td Adsorbed or another component pertussis combination vaccine are contraindications to vaccination.
Warnings: I.M. injections should be given with care in patients suffering from coagulation disorders because of the risk of hemorrhage.
If Adacel is used in poisons with malignancies, persons receiving immunosuppressive therapies, including irradiation, antimetabolites, alkylating agents, cytotoxic drugs, or persons who are otherwise immunocompromised (including HIV-infected individuals, transplant recipients, persons suffering from autoimmune disorders), the expected immune response may not be obtained.
Corticosteroid therapy can result in immunosuppression although the exact dose and duration of therapy required to suppress the immune system is not well defined. Persons treated with high doses of systemic steroids, e.g., ≥ 2 mg/kg/day of prednisone orally for more than 2 weeks, should be considered to have a compromised immune system. As with any vaccine, immunization with Adacel may not protect 100% of susceptible individuals.
The use of fractional doses in an attempt to reduce the severity of adverse reactions cannot be recommended because there is insufficient evidence on the safety or efficacy of such smaller doses.
Precautions: General: The possibility of allergic reactions in individuals sensitive to components of the vaccine should be evaluated. Epinephrine HCI solution (1:1000) and other appropriate agents should be available for immediate use in case an anaphylactic or acute hypersensitivity reaction occurs- Healthcare providers should be familiar with current recommendations for the initial management of anaphylaxis in non-hospital settings, including proper airway management.
Before administration of any vaccine, appropriate precautions should be taken to prevent adverse reactions. This includes a review of the patient's history with respect to possible hypersensitivity to the vaccine or similar vaccine, determination of previous immunization history, and the presence of any contraindications to immunization, current health status, and knowledge of the current literature concerning the use of the vaccine under consideration.
Frequent booster doses of tetanus or diphtheria toxoids in the presence of adequate or excessive serum levels of tetanus or diphtheria antitoxins have been associated with increased incidence and severity of reactions and should be avoided. If hypersensitivity to the diphtheria component is suspected, tetanus toxoid should be used for reinforcing doses. Special care should be taken to ensure that the product is not injected into a blood vessel (see Dosage).
Caution: A separate, sterile needle and syringe or a sterile disposable unit must be used for each individual patient to prevent the transmission of infectious agents.
There have been case reports of transmission of HIV and hepatitis by failure to scrupulously observe sterile technique. Needles should not be recapped and should be disposed of properly.
Before administration of Adacel, healthcare personnel should inform the patient or parent or guardian of the patient to be immunized of the benefits and risks of immunization, inquire about the recent health status of the patient and comply with any local requirements with respect to information to be provided to the patient before immunization.
Pregnancy and Lactation: The effect of Adacel on the development of the embryo and fetus has not been assessed. Vaccination in pregnancy is not recommended, unless there is a definite risk of acquiring pertussis. As the vaccine is inactivated, any risk to the embryo or the fetus is highly improbable. The benefits versus the risks of administering Adacel in pregnancy should carefully be evaluated when there is a high probable risk of exposure to a household contact or during an outbreak in the community.
The effect of administration of Adacel during lactation has not been assessed. As Adacel is inactivated, any risks to the mother or the infant are highly improbable. The benefits versus the risks of administering Adacel during lactation should carefully be evaluated by the healthcare provider, particularly when there is a high probable risk of disease transmission through exposure to a household contact, or during an outbreak in the community. The risks of disease transmission from the infected mother to the infant who may not have been fully immunized should also be evaluated.
Adverse Effects: In a clinical trial with 749 adolescents and adults given Adacel (n=449) or Td Adsorbed (n=15l), adverse events following Adacel were primarily localized to the site of injection. Pain was the most common local reaction (88.6%), while erythema and swelling were reported in 11.8% and 16.7%, respectively. These local adverse events were generally mild and transient in duration. Systemic adverse events that were reported after vaccination with Adacel were: fever (9.4%), vomiting (2.4%), headache (38.8%), diarrhea (10.0%), nausea (14.7%), chills (12.5%), generalized bodyache (20.0%), decreased energy (29.4%), and sore or swollen joints (9.1%). Of the 38.8% that reported headaches, 72.9% were mild and less than 5% were categorized as severe by the vaccinee. While decreased energy was common (29.4%), only 8.9% of vaccines considered it as significant. The adverse event rates observed with Adacel were comparable to those seen with the group that received Td Adsorbed (see Table II).

Localized reactions consisting of discomfort, pain, swelling and redness at the injection site may be associated with tetanus and diphtheria toxoids. Following booster doses, local erythema and swelling are not uncommon and Arthus-type sensitivity may occur. Severe local reactions are often associated with high levels of circulating antitoxin, usually resulting from over-immunization due to toxoid being given too frequently.
Systemic reactions, such as generalized urticaria, are uncommon. Influenza-like symptoms have been reported and usually occur within12 hours of vaccination with some diphtheria and tetanus toxoids.
Neurological complications such as peripheral neuropathies and demyelinating diseases of the CNS following tetanus toxoid or diphtheria toxoid have been documented but are rare. The US Institute of Medicine has concluded that the evidence is inadequate to accept or reject a causal relation between tetanus toxoid, DT or Td and demyelinating diseases of the CNS (acute demyelinating encephalomyelitis, transverse myelitis- optic neuritis) or peripheral mononeuropathy (other than those caused by direct intraneural injection).
The following neurologic illnesses have been reported as temporally associated with some vaccines containing tetanus toxoid: neurological complications including cochlear lesion, brachial plexus neuropathies, paralysis of the radial nerve, paralysis of the recurrent nerve, accommodation paresis, and EEG disturbances with encephalopathy (with or without permanent intellectual and/or motor function impairment). In the differential diagnosis of polyradiculoneuropathies following administration of a vaccine containing tetanus toxoid, tetanus toxoid should be considered as a possible etiology. The Institute of Medicine concluded that the evidence favors acceptance of a causal relation between tetanus toxoid and brachial neuritis.
On the basis of a case report and evidence that a vaccine-induced immunologic response can cause Guillain-Barre Syndrome (GBS), the Institute of Medicine concluded that tetanus toxoid-containing vaccines can trigger GBS in adults. No increased risk for GBS has been observed with the use of DPT in children.
Persistent nodules at the site of injection have occurred following the use of an adsorbed product, but this complication is unusual, and may be related to s.c. administration. Sterile abscess at the site of injection has been reported following use of some adsorbed vaccines (6 to 10 per million doses).
Rare cases of allergic or anaphylactic reaction (i.e., hives, swelling of the mouth, difficulty breathing, hypotension, or shock) have been reported after receiving some preparations containing diphtheria, tetanus and/or pertussis antigens. Death following vaccine-caused anaphylaxis has been reported.
As with any vaccine, there is the possibility that broad use of the vaccine could reveal rare adverse reactions not observed in clinical trials.
Physicians, nurses, and pharmacists should report any adverse occurrences temporally related to the administration of the product in accordance with local requirements and report to the Medical Director at Aventis Pasteur Limited, 1755 Steeles Avenue West, Toronto, Ontario, Canada, M2R 3T4.
Dosage: For persons who have previously been immunized against tetanus, diphtheria, and pertussis a dose of 0.5 mL should be administered as a reinforcing dose.
There are currently no data upon which to base a recommendation for the optimal interval for administering subsequent booster doses with Adacel.
Tetanus Prophylaxis in Wound Management: Table III summarizes the recommended use of immunizing agents in wound management. It is important to ascertain the number of doses of tetanus toxoid previously given and the interval since the last dose. If not clearly documented, a history of immunization should be regarded as "uncertain". When a tetanus booster dose is required, a combined preparation formulated for adults including tetanus and diphtheria toxoid is preferred. Appropriate cleansing and debridement of the wound is imperative. Booster doses given more frequently than recommended below may lead to adverse local and systemic reactions.
When travel to a developing country is planned more than 5 years after the last tetanus booster, it may be prudent to offer an early booster, since in some developing countries healthcare facilities may not be able to guarantee the safe administration of a booster dose if required.

(a) Adult type tetanus and diphtheria toxoid combination vaccine. If the patient is < 7 years old, an appropriate tetanus combination vaccine such as Tripacel or Pentacel is given.
(b)Primary immunization is at least 3 doses at age appropriate intervals.
(c)Tetanus immune globulin.
(d)Yes, unless there is documentation of a booster within the last 10 years.
(e)Yes, unless there is documentation of a booster within the last 5 years.
(f)No, unless individuals are known to have a significant immune deficiency state (e.g., HIV, agammaglobulinemia) since immune response to tetanus toxoid may be suboptimal.
Note: Tetanus toxoid, or a combined vaccine containing tetanus toxoid, and tetanus immune globulin should be administered in separate syringes at different sites.
Parenteral biological products should be inspected visually for extraneous particulate matter and/or discoloration before administration. If these conditions exist, the product should not be administered.
Shake the vial well to distribute uniformly the suspension before withdrawing each dose. When administering a dose from a rubber-stoppered vial, do not remove either the rubber stopper or the metal seal holding it in place. Aseptic technique must be used for withdrawal of each dose (See Precautions).
Before injection, the skin over the site to be injected should be cleansed with a suitable germicide. Administer the vaccine i.m. The preferred site is into the deltoid muscle.
After insertion of the needle, aspirate to ensure that the needle has not entered a blood vessel.
Do not inject i.v.
Each person who is immunized should be given a permanent personal immunization record. In addition, it is essential that the physician or nurse record the immunization history in the permanent medical record of each patient. This permanent office record should contain the name of the vaccine, date given, dose, manufacturer and lot number.
