Consumer medicine information (CMI) leaflet

Please read this leaflet carefully before you start using Quadracel.

What is in this leaflet

This leaflet answers some common questions about QUADRACEL.

It does not contain all the available information.

It does not take the place of talking to your doctor or pharmacist.

All medicines, including vaccines, have risks and benefits. Your doctor has weighed the risks of your child having QUADRACEL against the benefits they expect it will have.

If you have any concerns about this vaccine, ask your doctor, nurse or pharmacist.

Keep this leaflet. You may need to read it again.

What QUADRACEL is used for

QUADRACEL is a vaccine used to help prevent whooping cough, tetanus, diphtheria and polio.

This vaccine is for use in children up to 6 years of age, and is used in infants from the age of 2 months who are at the greatest risk from these diseases.

Polio, whooping cough, tetanus and diphtheria cause significant sickness and sometimes death in unvaccinated infants, children, and adults.

How it works

QUADRACEL works by causing the body to produce its own protection against whooping cough, tetanus, diphtheria, and polio. It does this by making substances called antibodies in the blood, which fight the bacteria and toxins that cause these diseases. If a vaccinated person comes into contact with these bacteria and toxins, the body is usually ready to destroy them.

It usually takes several weeks after vaccination to develop protection against these diseases.

Protection requires 3 doses of this vaccine or this vaccine used alternately with other vaccines protecting against the same diseases. A booster dose may be required between 15 months of age and six years.

Most children will produce enough antibodies against these diseases. However, as with all vaccines, 100% protection cannot be guaranteed.

The vaccine will not give your child any of these diseases.

The chance of a severe reaction from QUADRACEL is very small, but the risks from not being vaccinated against these diseases may be very serious.

Before you are given QUADRACEL

When your child must not be given it

Do not give QUADRACEL to a child who has:

  • an allergy to QUADRACEL or any of the ingredients listed at the end of this leaflet.
  • had an anaphylactic or other allergic reaction to a previous dose of this vaccine or another vaccine designed to protect against whooping cough, tetanus, diphtheria, polio, or Haemophilus influenzae type b.
  • had a serious nervous system disorder within 7 days after a previous whooping cough vaccine
  • progressive nervous system disorder such as infant spasm, uncontrolled epilepsy. The vaccination may be considered only after a treatment has been established and the condition is stabilised.
  • an illness with febrile or acute infection. The vaccination shall be postponed until after the child has recovered.

Symptoms of an allergic reaction may include:

  • shortness of breath, wheezing or difficulty breathing
  • swelling of the face, lips, tongue or other parts of the body
  • skin rash, itching or hives

Do not use QUADRACEL after the expiry date printed on the pack.

Do not use QUADRACEL if the packaging is torn or shows signs of tampering.

If you are not sure whether your child should have QUADRACEL, talk to your doctor or pharmacist.

Before your child is given it

Tell your doctor if your child has reacted to previous vaccination with any of the following:

  • life-threatening allergic reaction
  • shock-like state or being unresponsive for a long period of time
  • convulsions with or without high temperature
  • high temperature (greater than 40.5°C)
  • persistent crying lasting for more than 3 hours

Tell your doctor if your child has or has had any medical conditions, especially the following:

  • lowered immunity due to diseases (such as HIV/AIDS or cancer) or medicines (such as medicines used to treat cancer including radiation therapy)
  • a higher risk of convulsion than the general population
  • a bleeding disorder or taking blood-thinning medicines

Tell your doctor if your child has allergies to:

  • any other medicines
  • any other substances, such as foods, preservatives or dyes

Having other vaccines

Tell your doctor if your child has had any vaccines in the last 4 weeks. Your doctor will advise you if QUADRACEL is to be given with another vaccine as a separate injection.

How QUADRACEL is given

For infants under the age of 12 months, QUADRACEL is given as an injection into the upper thigh muscle. In older children who have started walking, the vaccine is usually injected into the upper arm muscle.

QUADRACEL should not be injected directly into the veins.

How much is given and when it is given

The primary immunisation schedule is one 0.5mL dose given at 2, 4 and 6 months of age. A booster dose may be given at 15 months to 6 years of age.

If your child misses a dose

If your child misses a dose, talk to your doctor and arrange another visit as soon as possible.

After having QUADRACEL

Things you must do

Keep an updated record of your child's vaccinations.

Keep follow-up appointments with your doctor or clinic. It is important your child has follow-up doses of QUADRACEL at the appropriate times to make sure the vaccine has the best chance of providing protection against whooping cough, tetanus, diphtheria, and polio.

Side effects

Tell your doctor or pharmacist as soon as possible if your child does not feel well after having QUADRACEL. QUADRACEL may have unwanted side effects in a few people. All medicines, including vaccines, can have side effects. Sometimes they are serious, most of the time they are not. Your child may need medical treatment if you get some of the side effects.

Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor or pharmacist if you notice any of the following and they worry you:

  • local reaction around the injection site such as redness, tenderness, pain or discomfort, or swelling
  • flushing or redness of the skin
  • fussiness
  • decreased activity
  • decreased eating
  • crying or screaming
  • fever
  • vomiting
  • diarrhoea
  • sleepiness

These are the more common side effects of QUADRACEL. Mostly these are mild and short-lived.

If any of the following happen, tell your doctor immediately or go to Accident and Emergency at your nearest hospital:

  • abscess at the injection site
  • sudden signs of allergic reactions such as rash, itching or hives on the skin, swelling of the face, lips, tongue or other parts of the body, shortness of breath, wheezing or trouble breathing
  • convulsions with or without high temperature
  • the child becomes pale, limp and unresponsive
  • pale skin or bluish appearance to finger nails or lips
  • unusual muscle slackness
  • nervous system disorders that may result in headache and fever, progressing to hallucinations, confusion, paralysis of part or all the body, disturbances of behaviour, speech and eye movements, stiff neck and sensitivity to light.

These are very serious side effects. Your child may need urgent medical attention or hospitalisation.

All of these side effects are very rare.

Very rarely children may experience swelling of the whole arm after the booster (4th) dose. This reaction occurs very rarely in association with all vaccines with similar active ingredients to QUADRACEL. It is a short-lived reaction, which resolves spontaneously without any permanent damage.

Other side effects not listed above may occur in some patients. Tell your doctor or pharmacist if you notice anything that is making your child feel unwell.

Do not be alarmed by this list of possible side effects.

Your child may not experience any of them.

After using QUADRACEL

Storage

QUADRACEL is usually stored in the doctor's surgery or clinic, or at the pharmacy. However, if you need to store QUADRACEL:

  • Keep it where children cannot reach it.
  • Keep QUADRACEL in the original pack until it is time for it to be given.
  • Keep it in the refrigerator, between 2°C and 8°C. Do not freeze QUADRACEL.

Freezing destroys the vaccine.

Pertussis vaccine acellular and diphtheria and tetanus toxoids (adsorbed) combined with inactivated poliovirus types 1, 2 and 3 (Vero cell).

2 Qualitative and Quantitative Composition

Each 0.5 mL dose of Quadracel contains:
Diphtheria toxoid ≥ 30 IU (15 Lf);
Tetanus toxoid ≥ 40 IU (5 Lf);
Pertussis toxoid (PT) 20 microgram;
Pertussis filamentous haemagglutinin (FHA) 20 microgram;
Pertactin (PRN) 3 microgram;
Pertussis fimbriae 2 + 3 (FIM) 5 microgram;
Poliovirus inactivated type 1, Vero (Mahoney) 29 D-antigen units;
Poliovirus inactivated type 2, Vero (MEF-1) 7 D-antigen units;
Poliovirus inactivated type 3, Vero (Saukett) 26 D-antigen units;
Absorbed on 1.5 mg aluminium phosphate (0.33 mg aluminium).
This product does not contain thiomersal.
The manufacture of this product includes exposure to bovine materials. No evidence exists that any case of variant Creutzfeldt-Jakob disease (vCJD) (considered to be the human form of bovine spongiform encephalopathy) has resulted from the administration of any vaccine product.
Diphtheria toxoid is a cell free preparation of diphtheria toxin detoxified with formaldehyde.
Tetanus toxoid is prepared by detoxification of tetanus toxin with formaldehyde.
Each of the three strains of poliovirus is individually grown in Vero cells cultivated on microcarriers. The single virus harvest is concentrated and purified, then inactivated with formaldehyde to produce the type 1, 2 or 3 monovalent. Monovalents of each type are then combined in appropriate quantities to produce a trivalent concentrate.
The 5 component pertussis antigens, pertussis toxoid (PT), pertussis filamentous haemagglutinin (FHA), pertactin (PRN) and pertussis fimbriae types 2 + 3 (FIM), contained in Quadracel are the same as those in Tripacel or Pediacel. Tripacel consists of an acellular pertussis vaccine combined with diphtheria and tetanus toxoids (DTPa), and has lesser amounts of PT and FHA, while Quadracel has pertussis formulations that are similar to Pediacel. Quadracel contains DTPa combined with inactivated poliovirus vaccine (IPV).
This product contains residual streptomycin sulfate, neomycin and polymyxin B sulfate.
For the full list of excipients, see Section 6.1 List of Excipients.

3 Pharmaceutical Form

Quadracel is a sterile, uniform, cloudy white to off-white suspension for injection.

4 Clinical Particulars

4.1 Therapeutic Indications

Quadracel is indicated for primary immunisation of children from the age of 2 months to 12 months against diphtheria, tetanus, pertussis, and poliomyelitis.
Quadracel is also indicated for the fourth dose for children from 15 months to six years of age who have been immunised previously with three doses of diphtheria, tetanus, pertussis and polio vaccines.

4.2 Dose and Method of Administration

Dose.

For primary immunisation of infants, the following routine Quadracel immunisation schedule is recommended: one 0.5 mL dose administered intramuscularly at 2, 4 and 6 months of age.
A fourth dose of Quadracel may be administered as a booster dose for children from 15 months to 6 years of age who have been immunised previously with up to three doses of diphtheria, tetanus, pertussis and polio vaccines.
The vaccine should not be administered to individuals after their seventh birthday (see Section 4.4 Special Warnings and Precautions for Use).
Infants born prematurely whose clinical condition is satisfactory should be vaccinated according to their chronological age from birth.

Administration.

Inspect for extraneous particulate matter and/or discolouration before use. If these conditions exist, the product should not be administered.
Shake the syringe well to distribute uniformly the suspension.
Administer the vaccine intramuscularly. The anterolateral thigh is the preferred site for vaccination in infants and children under 12 months of age. In older children, the deltoid muscle is usually large enough for injection. Separate syringes, separate injection sites and preferably separate limbs must be used in case of concomitant administration.
Do not administer the product intravascularly or subcutaneously.
Needles should not be recapped and should be disposed of properly.
Product is for single use in one patient only. Discard any residue.

4.3 Contraindications

Hypersensitivity.

Quadracel should not be administered to anyone with a history of severe allergic reaction to any component of the vaccine (components listed, see Section 2 Qualitative and Quantitative Composition; Section 6.1 List of Excipients) or after previous administration of the vaccine or a vaccine containing the same components or constituents.

Febrile or acute disease.

Vaccination should be postponed in cases of moderate or severe febrile and/or acute disease. Low-grade fever does not constitute a contraindication.

Neurological disorders.

The following events are contraindications to administration of any pertussis-containing vaccine, including Quadracel:
Encephalopathy (e.g. 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.
Progressive neurological disorder, including infantile spasms, uncontrolled epilepsy, progressive encephalopathy. Pertussis vaccine should not be administered to individuals with such conditions until a treatment regimen has been established and the condition has stabilised.

4.4 Special Warnings and Precautions for Use

Prior history of severe adverse events following 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 Quadracel should be based on careful consideration of potential benefits and possible risks. The following events require consideration of whether further doses of Quadracel should be given:
temperature of ≥ 40.5°C within 48 hours, not attributable to another identifiable cause;
collapse or shock-like state (hypotonic-hyporesponsive episode) within 48 hours;
persistent crying lasting ≥ 3 hours within 48 hours;
convulsions with or without fever within 3 days.

Hypersensitivity.

Bovine serum albumin, formaldehyde and glutaral have been used in the manufacturing process of this product and residual trace amounts may be present in the final product. Therefore, a hypersensitivity reaction may occur.
Neomycin, polymyxin B sulfate and streptomycin sulfate have been used in the manufacturing process of this product. As each dose may contain residual trace amounts of neomycin, polymyxin B sulfate and streptomycin sulfate, caution must be exercised when the vaccine is administered to individuals with hypersensitivity to these antibiotics (and other antibiotics of the same class).
The rates and severity of adverse events in recipients of tetanus toxoid are influenced by the number of prior doses and level of pre-existing antitoxins.
As with other injectable vaccines, appropriate medical treatment and supervision should always be available in case of anaphylactic reactions. Adrenaline (epinephrine) should always be readily available whenever the injection is given.

Protection.

As with any vaccine, immunisation with Quadracel may not protect 100% of susceptible individuals.

Neurological adverse events.

A review by the US Institute of Medicine (IOM) found evidence for a causal relation between tetanus toxoid and both brachial neuritis and Guillain-Barré syndrome (GBS). If GBS occurred within 6 weeks of receipt of prior vaccine containing tetanus toxoid, the decision to give Quadracel or any vaccine containing tetanus toxoid should be based on careful consideration of the potential benefits and possible risks.
For infants or children at higher risk for seizures than the general population, 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 Quadracel) and for the following 24 hours, to reduce the possibility of post-vaccination fever.
Hypotonic-hyporesponsive episodes (HHEs) rarely follow vaccination with whole-cell pertussis containing DTP vaccines and occur even less commonly after acellular pertussis-containing DTP vaccines and DT vaccines. A history of HHEs is not a contraindication to the use of acellular pertussis vaccines, but caution should be exercised in these cases.

Administration route-related precautions.

Do not administer by intravascular route.
As with all parenterals, this vaccine must be administered with caution to individuals with thrombocytopenia or bleeding disorders since bleeding may occur following an intramuscular injection.

Serious and severe adverse events-related precautions.

In persons who have a history of serious or severe reactions following a previous injection with the same vaccine or a vaccine containing similar components, the risks and benefits of vaccination must be carefully considered.
Before injection of any biological, the person responsible for administration must take all known precautions for the prevention of allergic or any other reaction. As with all parenteral vaccines, appropriate medical treatment and supervision should always be readily available in case of an anaphylactic event following administration of the vaccine.

Altered immune status.

The immunogenicity of Quadracel could be reduced by immunosuppressive treatment. In such cases, it is recommended to postpone the vaccination until the end of the immunosuppression. Nevertheless, vaccination of individuals with chronic immunodeficiency such as HIV infection is recommended even if the antibody response may be limited.

Syncope related precautions.

Syncope can occur following, or even before, any vaccination as a psychogenic response to the needle injection. Procedures should be in place to prevent falling and injury and to manage syncope.

Use in the elderly.

Quadracel should not be used in adults.

Paediatric use.

The potential risk of apnoea and the need for respiratory monitoring for 48-72 hours should be considered when administering the primary immunisation series to very premature infants (born ≤ 28 weeks of gestation) and particularly for those with a previous history of respiratory immaturity. As the benefit of vaccination is high in this group of infants, vaccination should not be withheld or delayed.

Effects on laboratory tests.

Interference of Quadracel with laboratory tests has not been studied.

4.5 Interactions with Other Medicines and Other Forms of Interactions

When both vaccines are indicated, Quadracel may be used to reconstitute Act-HIB (Haemophilus influenzae type b polysaccharide conjugated to tetanus protein) for simultaneous administration of all 5 antigens in a single injection. Quadracel must not be mixed in the same syringe with any other vaccines.
There are currently no data regarding the concomitant administration of Quadracel with MMR or hepatitis B vaccine. The Australian Immunisation Handbook accepts that inactivated vaccines can be given during the same visit at separate sites with separate syringes.
Immunosuppressive treatments may interfere with the development of the expected immune response.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

Quadracel has not been evaluated for the effects on fertility.
Not applicable. This vaccine is not intended for administration to women of child-bearing age.
 Not applicable. This vaccine is not intended for administration to women of child-bearing age.

4.7 Effects on Ability to Drive and Use Machines

Not applicable - for paediatric use only.

4.8 Adverse Effects (Undesirable Effects)

Clinical trials experience.

Safety information described below are based upon studies with Quadracel formulated with MRC-5 cell-derived IPV.
The most frequent reactions observed with Quadracel include redness and tenderness at the injection site, irritability and slight fever. These symptoms usually occur within the first 24 hours after vaccination and may continue for 24-48 hours. The rates of adverse events observed in children who received Quadracel at 2, 4, 6 and 18 months of age during a clinical trial with the vaccine in Canada are shown in Table 1.
In a clinical trial conducted in Sweden comparing three acellular pertussis vaccines and one whole cell DTP vaccine, 20,745 infants received a "hybrid" formulation of Tripacel which contained the same amounts of pertussis antigens as in Quadracel at 2, 4 and 6 or 3, 5 and 12 months of age. Rates of adverse events were less than or comparable to the rates in the other acellular pertussis vaccine and whole cell DTP groups in this study. The rates of reports of fever > 40.5°C and seizures or suspected seizures were significantly higher following whole cell DTP than following acellular pertussis vaccines. Rates of hypotonic/hyporesponsive episodes were comparable, with 29 reports following administration of Tripacel. No deaths or cases of encephalitis/acute encephalopathy, invasive bacterial infection, infantile spasms or anaphylactic reactions were reported within 48 hours of vaccination.
There are currently no clinical data to support administration of a fifth dose with Quadracel. In a study conducted by the U.S. National Institutes of Health (NIH), thirteen different formulations of acellular pertussis vaccines combined with diphtheria and tetanus toxoids (DTPa), including Tripacel (containing less PT and FHA than Quadracel), were evaluated for safety and immunogenicity when administered at 2, 4, 6 and 18 months, and 4 - 6 years of age. In an analysis of fourth and fifth dose follow-up studies from this multicenter trial, entire limb swelling was reported in 20 children (2%) of 1,015 children who received four consecutive doses of the same DTPa. It was found that large injection site reactions occurred more frequently after the fifth dose of DTPa than after the previous fourth dose. No reports were received of entire limb swelling in 121 children who received a fifth dose of the same DTPa. In 146 recipients who received 5 doses with different DTPa vaccines, 4 (2.7%) children were reported to have such swelling. In all reports the swelling subsided spontaneously and completely, without sequelae.

Data from postmarketing experience.

The following additional adverse events have been spontaneously reported during the postmarketing use of Quadracel worldwide. Because these events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to vaccine exposure.

Immune system disorders.

Anaphylactic reaction, hypersensitivity and allergic reactions (such as rash, urticaria, dyspnoea).

Psychiatric disorders.

Screaming.

Nervous system disorders.

Somnolence, convulsion, febrile convulsion, hypotonic-hyporesponsive episode, hypotonia.

Cardiac disorders.

Cyanosis.

Vascular disorders.

Pallor.

General disorders and administration site conditions.

Injection site reactions (including inflammation, mass, abscess and sterile abscess), oedema, injection site vesicles.
Listlessness.
Large injection site reactions (> 50 mm), including limb swelling which may extend from the injection site beyond one or both joints have been reported in children following Quadracel administration. These reactions usually start within 24-72 hours after vaccination, may be associated with erythema, warmth, tenderness or pain at the injection site, and resolve spontaneously within 3-5 days. The risk appears to be dependent on the number of prior doses of d/DTPa vaccine, with a greater risk following the 4th and 5th doses.

Reporting suspected adverse effects.

Reporting suspected adverse reactions after registration of the medicinal product is important. It allows continued monitoring of the benefit-risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions at www.tga.gov.au/reporting-problems.

4.9 Overdose

There are no reports of overdosage.
For information on the management of overdose, contact the Poisons Information Centre on 13 11 26.

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Pharmacotherapeutic group: Bacterial and Viral Vaccines, Combined, ATC code: J07CA02.

Clinical trials.

Clinical trial results described below are based upon studies with Quadracel formulated with MRC-5 cell-derived IPV.

Studies of protective efficacy of Tripacel against pertussis.

A randomised controlled double blind efficacy study was conducted in Sweden (Trial 1) where 2,551 infants received the regular formulation of Tripacel (containing lower concentrations of PT and FHA than Quadracel) and 2,539 received a control vaccine containing diphtheria and tetanus toxoids at 2, 4 and 6 months of age. Tripacel was shown to have an absolute vaccine efficacy of 85% (95% CI: 81%-89%) against pertussis disease (defined as at least 21 days of paroxysmal cough with culture, serologic or epidemiologic confirmation of infection with Bordetella pertussis). The incidence of local and systemic reactions after administration of Tripacel was comparable to the diphtheria tetanus vaccine (DT) control group.
A second randomised, double blind controlled efficacy trial (Trial 2) was carried out in Sweden with 82,892 infants comparing 3 acellular pertussis and one European whole cell DTP vaccines where 20,746 infants received a "hybrid" formulation of Tripacel (DTPa) which contained the same concentration of pertussis antigens as Quadracel, at 2, 4 and 6 (n = 2,552) or 3, 5 and 12 (n = 18,194) months of age. The "hybrid" Tripacel and the European whole cell DTP vaccine had similar and high efficacy against culture confirmed pertussis irrespective of duration. The other acellular pertussis combination vaccines were less effective. Rates of adverse events were less than or comparable to the rates observed in the other acellular pertussis and European whole cell DTP groups in this study.

Immunogenicity of Quadracel.

In a clinical trial conducted in Canada, infants received either Pediacel (n = 339), Penta [Act-HIB reconstituted with a whole cell pertussis DTP-IPV vaccine] (n = 112), Poliacel [Quadracel used to reconstitute Act-HIB] (n = 335), or Quadracel and Act-HIB, given at separate sites at the same visit (n = 113) at 2, 4 and 6 months of age. Of the 899 children enrolled, 798 received a fourth dose of the same vaccine at 18-20 months of age. Serologic responses are shown in Table 2.
The following antibody levels are considered to be protective: diphtheria, diphtheria antitoxin levels ≥ 0.01 IU/mL; tetanus, tetanus antitoxin levels ≥ 0.01 IU/mL; and poliomyelitis, neutralising poliovirus antibody titre levels ≥ 1:8.
The pertussis antibody responses observed with Quadracel were comparable to those observed following administration of the two different formulations of Tripacel (component pertussis vaccine combined with diphtheria and tetanus toxoids adsorbed), given at 2, 4 and 6 months, in the two Swedish pertussis efficacy trials (Table 3).
