1. What Hexyon is and what it is used for

Hexyon (DTaP-HB-IPV-Hib) is a vaccine used to protect against infectious diseases.
Hexyon helps protect children against diphtheria (D), tetanus (T), pertussis (aP), hepatitis B (HB), poliomyelitis (IPV), and serious diseases caused by Haemophilus influenzae type b (Hib). Hexyon is administered to children starting from the age of six weeks.
The vaccine works by stimulating the body to produce antibodies against the bacteria and viruses that cause the following infections:

• Diphtheria is an infectious disease that usually initially affects the throat, causing pain and swelling that may lead to suffocation. The bacteria responsible for the disease also produce a toxin (poison) that can damage the heart, kidneys, and nerves.
• Tetanus (often described as "lockjaw") is usually caused by bacteria entering a deep wound. The bacteria produce a toxin (poison) that causes muscle contractions, leading to breathing difficulties and possible suffocation.
• Pertussis (often called whooping cough) is a highly contagious disease affecting the airways. The pertussis bacterium causes severe coughing that may lead to breathing problems. The cough is often characterized by a distinctive "whoop" and may last for one or two months, or even longer. Pertussis may also cause ear infections, bronchial infections (bronchitis) that may persist for a long time, lung infections (pneumonia), seizures, brain damage, and even death.
• Hepatitis B is caused by the hepatitis B virus, which leads to swelling of the liver (inflammation). In some individuals, the virus may remain in the body for a long period and over time may lead to serious liver problems, including liver cancer.
• Poliomyelitis (often simply called polio) is caused by viruses that affect the nerves. It may lead to paralysis or muscle weakness, most often in the legs. Paralysis of the muscles controlling breathing and swallowing may result in death.
• Infections caused by Haemophilus influenzae type b (often simply called Hib) are serious bacterial infections and may cause meningitis (inflammation of the outer covering of the brain), which can lead to brain damage, deafness, epilepsy, or partial blindness. The infection may also cause inflammation and swelling of the throat, leading to difficulty in swallowing and breathing, and may affect other parts of the body such as the blood, lungs, skin, bones, and joints.

Important information regarding protection provided

• Hexyon helps prevent only those diseases caused by the specific bacteria or viruses targeted by the vaccine. The child may still contract illnesses with similar symptoms if caused by other bacteria or viruses.
• The vaccine does not contain live bacteria or viruses and cannot cause any of the infectious diseases it protects against.
• The vaccine does not protect against infections caused by other types of Haemophilus influenzae or meningitis caused by other microorganisms.
• Hexyon does not protect against liver infections caused by other agents such as hepatitis A, C, or E.
• Since symptoms of hepatitis B take a long time to develop, unrecognized hepatitis B infections may already be present at the time of vaccination. In such cases, the vaccine may not protect against hepatitis B.
• As with any other vaccine, Hexyon may not protect 100% of children who receive it.

2. What you should know before Hexyon is administered to the child

To ensure that Hexyon is suitable for the child, it is important that you inform the doctor or
healthcare professional if any of the following apply to the child. If there is anything you do not
understand, please ask your doctor, pharmacist, or healthcare professional for clarification.
Hexyon must not be administered if the child:

• has experienced breathing difficulties or facial swelling (anaphylactic reaction) after administration of Hexyon
• has had an allergic reaction:
  • to the active substances
  • to any of the excipients listed in section 6
  • to glutaraldehyde, formaldehyde, neomycin, streptomycin, or polymyxin B, as these substances are used during the vaccine manufacturing process
  • following administration of Hexyon or any other vaccine containing diphtheria, tetanus, pertussis, poliomyelitis, hepatitis B, or Hib
• has suffered a severe reaction affecting the brain (encephalopathy) within 7 days of a previous dose of a pertussis-containing vaccine (acellular or whole-cell pertussis)
• currently has an uncontrolled or serious condition affecting the brain (uncontrolled neurological disorder) or uncontrolled epilepsy.

Warnings and precautions
Before vaccination, inform the doctor, pharmacist, or healthcare professional if the child:

• has a moderate or high fever or an acute illness (e.g., fever, sore throat, cough, cold, or flu). Vaccination with Hexyon may need to be postponed until the child has recovered.
• has experienced any of the following events after receiving a pertussis-containing vaccine. In such cases, the decision to administer further doses of pertussis-containing vaccine should be carefully considered:
  • fever of 40°C or higher within 48 hours of vaccination not due to another identifiable cause;
  • collapse or shock-like state with episodes of hypotonia and hyporesponsiveness (decreased muscle tone) within 48 hours of vaccination;
• persistent, inconsolable crying lasting 3 hours or more within 48 hours of vaccination;
• seizures with or without fever within 3 days of vaccination.
  • previously had Guillain-Barré syndrome (temporary inflammation of nerves causing pain, paralysis, and altered sensation) or brachial neuritis (severe pain and reduced mobility of the arm and shoulder) after receiving a vaccine containing tetanus toxoid (an inactivated form of tetanus toxin). In this case, the decision to administer any other vaccine containing tetanus toxoid should be evaluated by the doctor.
  • is receiving treatment that lowers the body’s natural immune defenses or has a disease that weakens the immune system. In such cases, the immune response to the vaccine may be reduced. Vaccination is generally recommended to be delayed until after completion of treatment or recovery from illness. However, children with long-term immune system problems, such as HIV infection (AIDS), may still receive Hexyon, although the protection may not be as effective as in children with a healthy immune system.
  • has any chronic or acute illness such as chronic renal failure (inability of the kidneys to function properly).
  • has any undiagnosed brain disorder or uncontrolled epilepsy. The doctor will assess the potential benefit of vaccination.
  • has any blood disorder causing easy bruising or prolonged bleeding after minor cuts. The doctor will advise whether the child can receive Hexyon.

Fainting may occur after or even before any injection with a needle. Therefore, inform the
doctor or nurse if the child has previously fainted after an injection.
Other medicines, vaccines, and Hexyon
Inform the doctor or healthcare professional if the child is taking, has recently taken, or
might take any other medicines or vaccines.
Hexyon may be administered simultaneously with other vaccines such as pneumococcal vaccines,
measles-mumps-rubella vaccines, varicella vaccines, rotavirus vaccines, or meningococcal vaccines.
If administered at the same time as other vaccines, Hexyon will be given at separate injection sites.
Hexyon contains phenylalanine, potassium, and sodium
Hexyon contains 85 micrograms of phenylalanine in each 0.5-mL dose. Phenylalanine may be harmful to individuals with 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., essentially "potassium-free" and "sodium-free".

3. How Hexyon is administered

Hexyon will be administered to the child by a doctor or a healthcare professional trained in the use of vaccines and equipped to manage any uncommon severe allergic reactions (see section 4 Possible side effects).
Hexyon is given by injection into a muscle (intramuscular route, IM) in the upper leg or arm of the child. The vaccine will never be injected into a blood vessel, the skin, or under the skin.
The recommended dose is as follows:
Primary vaccination course
The child will receive either two injections given two months apart, or three injections given one or two months apart (at least four weeks apart). This vaccine should be used in accordance with the local vaccination schedule.
Subsequent injections (booster)
After the primary course of injections, the child will receive a booster dose, in accordance with local recommendations, at least 6 months after the last dose of the primary course. The doctor will inform you when this dose should be administered.
If the child has missed a dose of Hexyon
If the child has missed a scheduled injection, it is important to inform the doctor or healthcare professional, who will decide when to administer it.
It is important to follow the instructions of the doctor or healthcare professional so that the child completes the entire vaccination course. Otherwise, the child may not be fully protected against the diseases that Hexyon prevents.
If you have further questions about the use of this vaccine, consult your doctor, pharmacist, or healthcare professional.

4. Possible side effects

Like all medicines, this vaccine may cause side effects, although not everybody gets them.
Severe allergic reactions (anaphylactic reaction)
If any of the following symptoms occur after leaving the place (e.g. hospital, clinic) where the child was vaccinated, seek medical help IMMEDIATELY:

• difficulty breathing
• blue tongue or lips
• rash
• swelling of the face or throat
• sudden and severe feeling of illness with low blood pressure causing dizziness and loss of consciousness, accompanied by breathing difficulties and rapid heartbeat.

When signs or symptoms of anaphylactic reaction occur, they usually appear immediately after the injection, while the child is still in the hospital or clinic.
Severe allergic reactions are rare (may affect up to 1 in 1,000 children) following administration of this vaccine.
Other side effects
If the child experiences any of the following side effects, inform your doctor, healthcare professional, or pharmacist.

• Very common side effects (may affect more than 1 in 10 children) are:
  • loss of appetite
  • crying
  • sleepiness
• 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 children) are:
• prolonged or unusual crying

• hardening at the injection site
  • Uncommon side effects (may affect up to 1 in 100 children) are:
• allergic reactions
• high fever (temperature of 39.6°C or higher)
• nodule at the injection site
  • Rare side effects (may affect up to 1 in 1,000 children) are:
• rash
• extensive local reactions at the injection site (more than 5 cm), including extensive swelling of the limb from the injection site extending beyond one or both joints. These reactions occur within 24–72 hours after vaccination, may be associated with redness, warmth, increased sensitivity or pain at the injection site, and usually resolve within 3–5 days without treatment.
• seizures with or without fever.
  • Very rare side effects (may affect up to 1 in 10,000 children) are:
• episodes resembling shock or pallor, muscle weakness and reduced responsiveness for a period of time (hypotonic-hyporesponsive episodes, HHE).

Potential side effects
Other side effects not listed above have been reported occasionally following the use of other vaccines containing diphtheria, pertussis, poliomyelitis, hepatitis B or Hib, but not directly with Hexyon:

• Temporary inflammation of nerves causing pain, paralysis and sensory disturbances (Guillain-Barré syndrome), severe pain and reduced mobility of the arm and shoulder (brachial neuritis), have been reported following administration of tetanus-containing vaccines.
• Inflammation of certain nerves causing sensory disturbances or limb weakness (polyradiculoneuritis), facial paralysis, visual disturbances, diminished or loss of vision (optic neuritis), inflammatory diseases of the brain and spinal cord (demyelination of the central nervous system, multiple sclerosis) have been reported following administration of vaccines containing hepatitis B antigen.
• Swelling or inflammation of the brain (encephalopathy/encephalitis).
• In very premature infants (born at 28 weeks of gestation or earlier), episodes of breathing interruption longer than normal may occur, lasting for 2–3 days after vaccination.
• Swelling of one or both feet and lower limbs. This reaction may occur together with bluish skin discoloration (cyanosis), redness, small areas of bleeding under the skin (transient purpura) and severe crying following vaccination with Haemophilus influenzae type b-containing vaccines. If these reactions occur, they usually follow the first injections and appear within the first hours after vaccination. All symptoms should resolve completely within 24 hours without requiring treatment.

1. What Hexyon is and what it is used for

Hexyon (DTaP-HB-IPV-Hib) is a vaccine used to protect against infectious diseases.
Hexyon helps protect children against diphtheria (D), tetanus (T), pertussis (aP), hepatitis B (HB),
poliomyelitis (IPV), and serious diseases caused by Haemophilus influenzae type b (Hib). Hexyon is
administered to children starting from six weeks of age.
The vaccine works by stimulating the body to produce antibodies against the bacteria and viruses that
cause the following infections:

• Diphtheria is an infectious disease that usually begins by affecting the throat, causing pain and swelling that may lead to suffocation. The bacteria responsible for the disease also produce a toxin (poison) that can damage the heart, kidneys, and nerves.
• Tetanus (often described as "lockjaw") is usually caused by bacteria entering a deep wound. The bacteria produce a toxin (poison) that causes muscle contractions, leading to breathing difficulties and possible suffocation.
• Pertussis (often called whooping cough) is a highly contagious disease affecting the airways. The pertussis bacterium causes severe coughing that may lead to breathing problems. The cough is often characterized by a typical "whoop" sound and can last for one or two months, or even longer. Pertussis may also cause ear infections, bronchial infections (bronchitis) that can persist for a long time, lung infections (pneumonia), seizures, brain damage, and even death.
• Hepatitis B is caused by the hepatitis B virus, which causes the liver to swell (inflammation). In some people, the virus may remain in the body for a long time and may eventually lead to serious liver problems, including liver cancer.
• Poliomyelitis (often simply called polio) is caused by viruses that affect the nervous system. It may lead to paralysis or muscle weakness, most often in the legs. Paralysis of the muscles controlling breathing and swallowing can result in death.
• Infections caused by Haemophilus influenzae type b (often simply called Hib) are serious bacterial infections and may cause meningitis (inflammation of the outer covering of the brain), which can lead to brain damage, deafness, epilepsy, or partial blindness. The infection may also cause inflammation and swelling of the throat, leading to difficulty in

swallowing and breathing, and the infection can affect other parts of the body such as the blood,
lungs, skin, bones, and joints.
Important information regarding protection provided

• Hexyon helps prevent only those diseases caused by the specific bacteria or viruses targeted by the vaccine. The child may still contract diseases with similar symptoms if caused by other bacteria or viruses.
• The vaccine does not contain live bacteria or viruses and cannot cause any of the infectious diseases it protects against.
• The vaccine does not protect against infections caused by other types of Haemophilus influenzae or meningitis due to other microorganisms.
• Hexyon does not protect against liver infections caused by other agents such as hepatitis A, C, and E.
• Since symptoms of hepatitis B take a long time to develop, unrecognized hepatitis B infections may already be present at the time of vaccination. In such cases, the vaccine may not protect against hepatitis B.
• As with any vaccine, Hexyon may not protect 100% of children who receive it.

2. What you should know before Hexyon is administered to the child

To ensure that Hexyon is suitable for the child, it is important that you inform the doctor or
healthcare professional if any of the following apply. If there is anything you do not
understand, please ask the doctor, pharmacist, or healthcare professional for clarification.
Hexyon must not be administered if the child:

• has experienced breathing difficulties or facial swelling (anaphylactic reaction) after receiving Hexyon
• has had an allergic reaction
  • to the active substances
  • to any of the excipients listed in section 6
  • to glutaraldehyde, formaldehyde, neomycin, streptomycin, or polymyxin B, as these substances are used during the vaccine production process
  • following administration of Hexyon or any other vaccine containing diphtheria, tetanus, pertussis, poliomyelitis, hepatitis B, or Hib
• has suffered a severe reaction affecting the brain (encephalopathy) within 7 days of a previous dose of a pertussis-containing vaccine (acellular or whole-cell pertussis)
• has an uncontrolled or serious neurological disorder affecting the brain or uncontrolled epilepsy.

Warnings and precautions
Before vaccination, inform the doctor, pharmacist, or healthcare professional if the child:

• has a moderate or high fever or an acute illness (e.g., fever, sore throat, cough, cold, or flu). In such cases, administration of Hexyon may need to be postponed until the child has recovered.
• has experienced any of the following events after receiving a pertussis-containing vaccine. In such cases, the decision to administer further doses of pertussis-containing vaccine should be carefully considered:
  • fever of 40°C or higher within 48 hours after vaccination, not due to another identifiable cause;
  • collapse or shock-like state with episodes of hypotonia-hyporesponsiveness (decreased muscle tone) within 48 hours after vaccination;
  • persistent, inconsolable crying lasting 3 hours or more within 48 hours after vaccination;
  • seizures with or without fever within 3 days after vaccination.
  • previously experienced Guillain-Barré syndrome (temporary inflammation of the nerves causing pain, paralysis, and altered sensation) or brachial neuritis (severe pain and reduced mobility of the arm and shoulder) after receiving a vaccine containing tetanus toxoid (an inactivated form of tetanus toxin). In such cases, the decision to administer any further vaccine containing tetanus toxoid should be evaluated by the doctor.
  • is currently receiving treatment that suppresses the body's natural immune defenses or has a disease that weakens the immune system. In these cases, the immune response to the vaccine may be reduced. Vaccination is generally recommended to be delayed until the end of treatment or recovery from illness. However, children with long-term immune system disorders, such as HIV infection (AIDS), may still receive Hexyon, although the protection provided may not be as effective as in children with a healthy immune system.
  • has any chronic or acute illness such as chronic renal failure (kidneys unable to function properly).
  • has any undiagnosed neurological disorder or uncontrolled epilepsy. The doctor will assess the potential benefit of vaccination.
  • has any blood disorder causing easy bruising or prolonged bleeding after minor cuts. The doctor will advise whether the child can receive Hexyon.

Fainting may occur after or even before any injection with a needle. Therefore, inform the
doctor or nurse if the child has previously fainted after an injection.
Other medicines, vaccines, and Hexyon
Inform the doctor or healthcare professional if the child is taking, has recently taken, or
might take any other medicines or vaccines.
Hexyon may be administered simultaneously with other vaccines such as pneumococcal vaccines,
measles-mumps-rubella vaccines, varicella vaccines, rotavirus vaccines, or meningococcal vaccines.
If administered at the same time as other vaccines, Hexyon will be given at separate injection sites.
Hexyon contains phenylalanine, potassium, and sodium
Hexyon contains 85 micrograms of phenylalanine in each 0.5-mL dose. Phenylalanine may
be harmful for individuals with 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., essentially "potassium-free" and "sodium-free".

3. How Hexyon is given

Hexyon will be administered to the child by a doctor or a healthcare professional who is properly trained in the use of vaccines and equipped to manage any uncommon severe allergic reactions (see section 4 Possible side effects).
Hexyon is given by injection into a muscle (intramuscular route, IM) in the upper leg or arm of the child. The vaccine will never be injected into a blood vessel, the skin, or under the skin.
The recommended dose is as follows:
Primary vaccination cycle (primary vaccination)
The child will receive two injections given two months apart or three injections given one or two months apart (at least four weeks apart). This vaccine should be used in accordance with the local vaccination schedule.
Subsequent injections (booster)
After the primary vaccination cycle, the child will receive a booster dose, in accordance with local recommendations, at least 6 months after the last dose of the primary cycle. Your doctor will inform you when this dose should be given.
If the child has missed a dose of Hexyon
If the child has missed a scheduled injection, it is important to inform the doctor or healthcare professional, who will decide when it should be administered.
It is important to follow the doctor's or healthcare professional's instructions so that the child completes the entire vaccination course. Otherwise, the child may not be fully protected against the diseases prevented by Hexyon.
If you have further questions about the use of this vaccine, consult your doctor, pharmacist, or healthcare professional.

Potential side effects
Other side effects not listed above have been reported occasionally with the use of other vaccines containing diphtheria, pertussis, poliomyelitis, hepatitis B or Hib, but not directly with Hexyon:

• Temporary inflammation of nerves causing pain, paralysis and sensory disturbances (Guillain-Barré syndrome), severe pain and reduced mobility of the arm and shoulder (brachial neuritis), have been reported following administration of vaccines containing tetanus.
• Inflammation of certain nerves causing sensory disturbances or limb weakness (polyradiculoneuritis), facial paralysis, visual disturbances, diminished or loss of vision (optic neuritis), inflammatory disease of the brain and spinal cord (central nervous system demyelination, multiple sclerosis) have been reported following administration of vaccines containing hepatitis B antigen.
• Swelling or inflammation of the brain (encephalopathy/encephalitis).
• In very premature infants (born at 28 weeks of gestation or earlier), episodes of breathing interruption longer than normal may occur, manifesting for 2–3 days after vaccination.
• Swelling of one or both feet and lower limbs. This reaction may occur together with bluish skin discoloration (cyanosis), redness, small areas of bleeding under the skin (transient purpura), and severe crying following vaccination with vaccines containing Haemophilus influenzae type b. If these reactions occur, they usually appear after the first injections and are observed within the first few hours after vaccination. All symptoms should completely resolve within 24 hours without requiring treatment.
