1. What is Hexyon and what is it used for

Hexyon (DtaP-IPV-HB-Hib) is a vaccine used to protect against infectious diseases.

Hexyon helps protect against diphtheria, tetanus, pertussis, hepatitis B, poliomyelitis, and serious diseases caused by Haemophilus influenzaetype b. Hexyon is given to children from 6 weeks of age.

The vaccine works by making the body produce its own protection (antibodies) against the bacteria and viruses that cause these different infections:

• Diphtheria is an infectious disease that usually affects the throat first. In the throat, the infection causes pain and swelling that can lead to suffocation. The bacteria that cause this disease also produce a toxin (poison) that can damage the heart, kidneys, and nerves.
• Tetanus usually occurs when tetanus bacteria enter a deep wound. The bacteria produce a toxin (poison) that causes muscle spasms, leading to an inability to breathe and the possibility of suffocation.
• Pertussis (also called whooping cough) is a highly contagious disease that affects the respiratory tract. This causes severe coughing attacks that can lead to respiratory problems. The coughing attacks often have a characteristic "inspiratory sound". The cough can last from one to two months or more. Pertussis can also cause ear infections, chest infections (bronchitis), which can last a long time, lung infections (pneumonia), seizures, brain damage, and even death.
• Hepatitis B is caused by the hepatitis B virus. This causes the liver to become inflamed (inflammation). In some people, the virus can remain in the body for a long time and eventually cause serious liver problems, including liver cancer.
• Poliomyelitis (also called polio) is caused by viruses that affect the nerves. It can lead to paralysis or muscle weakness, most often in the legs. Paralysis of the muscles that control breathing and swallowing can be fatal.
• Haemophilus influenzaetype b infections are serious bacterial infections and can cause meningitis (inflammation of the membranes that surround the brain), which can cause brain damage, deafness, epilepsy, or partial blindness. The infection can also cause inflammation and swelling of the throat, making it difficult to swallow and breathe. The infection can affect other parts of the body, such as the blood, lungs, skin, bones, and joints.

Important information about the protection provided

• Hexyon will only help prevent these diseases if they are caused by the bacteria or viruses for which the vaccine is intended. Your child may still contract diseases with similar symptoms caused by other bacteria or viruses.
• The vaccine does not contain any live bacteria or virus and cannot cause any of the infectious diseases it protects against.
• This vaccine does not protect against infections caused by other types of Haemophilus influenzaeor against meningitis caused by other microorganisms.
• Hexyon will not protect against infectious hepatitis caused by other agents such as hepatitis A, hepatitis C, and hepatitis E.
• Because the symptoms of hepatitis B take a long time to develop, it is possible that an unidentified hepatitis B infection may be present at the time of vaccination. In such cases, the vaccine may not prevent hepatitis B infection.
• As with any other vaccine, it is possible that Hexyon may not protect 100% of vaccinated children.

2. What you need to know before your child is given Hexyon

In order to ensure that Hexyon is suitable for your child, it is important that you inform your doctor or nurse if your child has any of the following characteristics. If there is anything you do not understand, ask your doctor, pharmacist, or nurse.

Do not use Hexyon if your child:

• has had a respiratory disorder or swelling of the face (anaphylactic reaction) after administration of Hexyon.
• has had an allergic reaction

• to the active substances,
• to any of the other components listed in section 6,
• to glutaraldehyde, formaldehyde, neomycin, streptomycin, and polymyxin B, as these substances are used during the manufacturing process,
• after previous administration of Hexyon or any other vaccine that contains diphtheria, tetanus, pertussis, poliomyelitis, hepatitis B, or Hib.

• has had a severe reaction that affects the brain (encephalopathy) within 7 days of administration of a previous dose of a pertussis vaccine (acellular or whole cell).
• has an uncontrolled or severe disease that affects the brain and nervous system (uncontrolled neurological disorder) or uncontrolled epilepsy.

Warnings and precautions

Before vaccination, consult your doctor, pharmacist, or nurse if your child:

• has a moderate or high temperature or an acute illness (fever, sore throat, cough, cold, or flu). It may be necessary to delay vaccination with Hexyon until your child feels better.
• has experienced any of the following adverse events after receiving a pertussis vaccine, the decision to administer further doses of vaccine containing the pertussis component should be carefully evaluated:

• fever of 40°C or higher within 48 hours of vaccination that was not due to any other identifiable cause.
• collapse or shock-like state with hypotonic-hyporesponsive episode (weakness) within 48 hours of vaccination.
• prolonged crying, lasting 3 hours or more, within 48 hours of vaccination.
• seizures (convulsions) with or without fever, within 3 days of vaccination.

• has previously had Guillain-Barré syndrome (temporary inflammation of the nerves that causes pain, paralysis, and sensitivity disorders) or brachial neuritis (severe pain and reduced mobility in the arm and shoulder) after administration of a vaccine that contains tetanus toxoid (an inactivated form of tetanus toxoid). In this case, your doctor will evaluate the decision to administer any vaccine that contains tetanus toxoid.
• is receiving treatment that suppresses their immune system (the body's natural defenses) or has any disease that causes immunodeficiency. In these cases, the immune response to the vaccine may be reduced. Therefore, it is recommended to delay vaccination until the end of treatment or disease. However, children with long-term problems with their immune system, such as HIV infection (AIDS), may be given Hexyon, but protection may not be as good as in children with a healthy immune system.
• has a chronic or acute illness, including chronic kidney failure or kidney failure.
• has any undiagnosed or uncontrolled brain disease or uncontrolled epilepsy. Your doctor will evaluate the potential benefits of vaccination.
• has any blood disorder that causes easy bruising or prolonged bleeding after minor cuts. Your doctor will advise on the convenience or not of administering Hexyon to your child.

Use of Hexyon with other vaccines or medicines

Tell your doctor or nurse if your child is using, has recently used, or might use any other medicine or vaccine.

Hexyon can be administered at the same time as other vaccines, such as pneumococcal vaccines, measles-mumps-rubella vaccines, varicella vaccines, rotavirus vaccines, or meningococcal vaccines.

When administered at the same time as other vaccines, Hexyon will be administered in different injection sites.

Fainting can occur after, or even before, any injection with a needle. Therefore, inform your doctor or nurse if your child has fainted with a previous injection.

Hexyon contains phenylalanine, potassium, and sodium

Hexyon contains 85 micrograms of phenylalanine per 0.5 ml dose. Phenylalanine may be harmful if you have phenylketonuria (PKU), a rare genetic disorder in which phenylalanine accumulates because the body cannot eliminate it properly.

Hexyon contains less than 1 mmol of potassium (39 mg) and less than 1 mmol of sodium (23 mg) per dose, i.e., it is essentially "potassium-free" and "sodium-free".

3. How to use Hexyon

Hexyon will be administered to your child by a doctor or nurse who is properly trained in the use of vaccines and equipped to respond to any rare, severe allergic reaction that may occur after injection (see section 4 "Possible side effects").

Hexyon is administered by injection into a muscle (intramuscularly, IM) in the upper leg or arm of your child. The vaccine should never be administered into a blood vessel or under or into the skin.

The recommended dose is as follows:

Primary vaccination cycle (primary vaccination)

Your child will receive two injections administered at an interval of two months or three injections administered at an interval of one to two months (at least four weeks apart). This vaccine should be used according to the local vaccination schedule.

Additional injections (booster vaccination)

After the primary vaccination cycle, your child will receive a booster dose, according to local recommendations, at least 6 months after the last dose of the primary vaccination cycle. Your doctor will advise on when this dose should be administered.

If your child misses a dose of Hexyon

If your child misses a scheduled injection, it is important that you inform your doctor or nurse, they will decide when to administer the missed dose.

It is important to follow the doctor's or nurse's instructions to ensure your child completes the vaccination cycle. Otherwise, your child may not be fully protected against the diseases.

If you have any further questions on the use of this medicine, ask your doctor, pharmacist, or nurse.

4. Possible side effects

Like all medicines, this vaccine can cause side effects, although not everybody gets them.

Severe allergic reactions (anaphylactic reaction)

If any of the following symptoms occur after leaving the place where your child received the injection, you should consult a doctor IMMEDIATELY:

• difficulty breathing
• bluish discoloration of the tongue or lips
• rash
• swelling of the face or throat
• sudden and severe discomfort with a drop in blood pressure that causes dizziness and loss of consciousness, rapid heart rate associated with respiratory disorders

When these signs and symptoms (signs or symptoms of an anaphylactic reaction) occur, they usually develop rapidly after injection and while the child is still in the clinic or doctor's office.

The possibility of severe allergic reactions occurring after receiving this vaccine is rare (may affect up to 1 in 1,000 people).

Other side effects

If your child experiences any of the following side effects, consult your doctor, nurse, or pharmacist.

• Very common side effects (may affect more than 1 in 10 people) are:

• loss of appetite (anorexia)
• crying
• sleepiness (somnolence)
• vomiting
• fever (temperature of 38°C or higher)
• irritability
• pain, redness, or swelling at the injection site

• Common side effects (may affect up to 1 in 10 people) are:

• abnormal crying (prolonged crying)
• diarrhea
• hardening at the injection site (induration)

• Uncommon side effects (may affect up to 1 in 100 people) are:

• allergic reaction
• high fever (temperature of 39.6°C or higher)
• lump (nodule) at the injection site

• Rare side effects (may affect up to 1 in 1,000 people) are:

• rash
• extensive reactions at the injection site (larger than 5 cm), including extensive swelling of a limb that extends from the injection site beyond one or both joints. These reactions start within 24-72 hours after vaccination, may be associated with redness, heat, pain, or swelling at the injection site, and resolve within 3-5 days without treatment.
• seizures (convulsions) with or without fever.

• Very rare side effects (may affect up to 1 in 10,000 people) are:

• episodes in which your child enters a shock-like state or becomes pale, weak, and unresponsive for a period (hypotonic-hyporesponsive episodes, HHE).

Possible side effects

Other side effects have been reported occasionally with other vaccines that contain diphtheria, tetanus, pertussis, poliomyelitis, hepatitis B, or Hib, and not directly with Hexyon:

• Guillain-Barré syndrome (temporary inflammation of the nerves that causes pain, paralysis, and sensitivity disorders), severe pain, and reduced mobility in the arm and shoulder (brachial neuritis) have been reported after administration of a vaccine that contains tetanus toxoid.
• Polyradiculoneuritis (inflammation of the nerves that causes sensory disorders or weakness in the arms and/or legs), facial paralysis, visual disorders, blindness, or sudden loss of vision (optic neuritis), inflammatory disease of the brain and spinal cord (demyelination of the central nervous system, multiple sclerosis) have been reported after administration of vaccines that contain the hepatitis B antigen.
• Brain inflammation or infection (encephalopathy/encephalitis).
• In children born very prematurely (at 28 weeks of gestation or earlier), longer intervals between breaths than normal may occur for 2-3 days after vaccination.
• Swelling or inflammation of the brain. This can cause a range of symptoms, including headache, confusion, and seizures.
• Swelling of one or both feet and lower limbs. This may occur with a bluish discoloration of the skin (cyanosis), redness, small areas of bleeding under the skin (transient purpura), and severe crying, after administration of vaccines that contain Haemophilus influenzaetype b. If this reaction occurs, it will mainly happen after the first injections and will be seen in the first hours after vaccination. All symptoms will resolve completely within 24 hours without treatment.
