Vaccine against diphtheria, tetanus, pertussis (acellular, component), hepatitis B (rDNA), polio (inactivated), and Haemophilus influenzae type b conjugate ( adsorbed )
1. What Hexyon is and what it is 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, polio, and serious diseases caused by Haemophilus influenzae type b. Hexyon is given to children from six weeks of age.
The vaccine works by getting the body to produce its protection ( antibodies ) against bacteria and viruses that cause these various infections:
- Diphtheria is an infectious disease that usually first affects the throat. In the throat, infection causes a pain and swelling that can lead to suffocation. Bacteria that cause the disease also produce a toxin (poison) that can damage the heart, kidneys and nerves.
- tetanus ( tetanus ) is usually caused by tetanus bacteria entering the body through a deep wound. The bacteria produce a toxin (poison) that causes muscle spasms which lead to difficulty breathing and the risk of suffocation.
- whooping cough (pertussis) is a highly contagious disease that affects the respiratory tract. The disease causes severe cough that can cause breathing problems. The cough often has a “peeking” sound. The cough can last for one to two months or longer. Whooping cough can also cause ear infections, respiratory tract infections ( bronchitis ) that can last for a long time, pneumonia , seizures, brain damage and even death.
- hepatitis B is caused by the hepatitis B virus . It causes the liver to swell (become inflamed). In some people, the virus can remain in the body for a long time and can eventually cause serious liver problems, including liver cancer.
- polio (poliomyelitis) is caused by viruses that affect the nerves. It can lead to paralysis or muscle weakness, usually in the legs. Paralysis of muscles that control breathing and swallowing can cause death.
- infection with Haemophilus influenzae type b (often called just Hib) are serious bacterial infections that can cause meningitis ( inflammation of the outer membranes of the brain), which can lead to brain damage, deafness, epilepsy or partial blindness. Infection can also cause inflammation and swelling in the throat, which in turn leads to difficulty breathing and swallowing; infection can affect other parts of the body such as the blood, lungs, skin, bone tissue and joints.
Important information about how the vaccine works
- Hexyon only helps to protect against these diseases if they are caused by the bacteria and viruses for which the vaccine is intended. Your child can get diseases with similar symptoms if they are caused by other bacteria or viruses .
- The vaccine does not contain any live bacteria or viruses and can not cause any of the infectious diseases that it protects against.
- This vaccine does not protect against infection caused by other types of Haemophilus influenzae , nor against meningitis caused by other microorganisms .
- Hexyon does not protect against hepatitis infection caused by other viruses such as hepatitis A, hepatitis C and hepatitis E or other liver pathogens.
- Because symptoms of hepatitis B take a long time to develop, it is possible that undetected hepatitis B infection may occur at the time of vaccination. The vaccine may not be able to prevent hepatitis B infection in such cases.
- As with all vaccines, Hexyon may not provide protection in 100% of the children who receive the vaccine.
2. What you need to know before your child receives Hexyon
Do not use Hexyon
To ensure that Hexyon is suitable for your child, it is important to talk to a doctor or nurse if any of the points listed below apply to your child. If there is anything you do not understand, talk to your doctor, pharmacist, or nurse.
Do not use Hexyon if your child:
- have had respiratory problems or swelling of the face ( anaphylactic reaction ) after administration of Hexyon
- have had an allergic reaction
- against the active substances
- against any of the other ingredients listed in section 6
- against glutaraldehyde, formaldehyde, neomycin , streptomycin or polymyxin B as these substances are used during the manufacturing process.
- after previous administration of Hexyon or other vaccines containing diphtheria , tetanus, pertussis, polio, hepatitis B or Hib
- have had a severe reaction affecting the brain ( encephalopathy ) within 7 days after a previous dose of a pertussis vaccine (acellular or whole cell pertussis)
- have an uncontrolled disease state or serious illness that affects the brain and nervous system (uncontrolled neurological disorder) or uncontrolled epilepsy .
Warnings and cautions
Talk to your doctor, pharmacist, or nurse before vaccination about your child:
- have a moderate or high fever or an acute illness (eg fever, sore throat, cough, cold or flu ). Vaccination with Hexyon may need to be postponed until your child feels better.
- have had any of the following after receiving the pertussis vaccine, as the decision to give additional doses of pertussis vaccine needs to be carefully considered:
- fever at 40 ° C or above within 48 hours after vaccination due to no other identifiable cause.
- collapse or shock-like condition with hypotonic-hyporesponsive episode (loss of energy) within 48 hours after vaccination.
- persistent and inconsolable crying lasting 3 hours or more and occurring within 48 hours after vaccination.
- seizures with or without fever that occur within 3 days after vaccination.
- previously had Guillain-Barré syndrome (temporary inflammation of the nerves causing pain, paralysis and sensory disturbances) or brachial neuritis (severe pain and reduced mobility in the arm and shoulder) after receiving a vaccine containing tetanus toxoid (an inactivated form of tetanus vaccine). In this case, the decision to give additional vaccines containing tetanus toxoid should be evaluated by a physician.
- follows a treatment that suppresses the immune system (the body’s natural defenses) or has a disease that causes a weakened immune system. In these cases, the immune response to the vaccine may be reduced. Then it is normally recommended that the vaccination be postponed until the end of the treatment or the disease. Children with long-term problems with the immune system such as HIV – infection ( AIDS ) can still be Hexyon but the protection may not be as good as in children whose immune system is healthy.
- suffers from an acute or chronic disease, including chronic renal impairment or renal failure (kidneys do not function properly).
- suffers from an undiagnosed disease of the brain or uncontrolled epilepsy . Your doctor will then assess the potential benefits of vaccination.
- have a bleeding disorder that causes slight bruising or bleeding for a long time after minor wounds. Your doctor will tell you if your child can get Hexyon.
Fainting can occur after, or even before, the needle stick. Therefore, tell your doctor or nurse if your child has previously fainted in connection with needle sticks.
Other medicines or vaccines and Hexyon
Tell your doctor or nurse if your child is taking, has recently taken, or might take any other medicines or vaccines.
Hexyon can be given at the same time as other vaccines such as pneumococcal vaccines, measles-mumps-rubella vaccines, rotavirus vaccines, or meningococcal vaccines.
When Hexyon is given at the same time as other vaccines, the injections will be given in different places.
Hexyon contains phenylalanine, potassium and sodium
Hexyon contains 85 micrograms of phenylalanine per 0.5 ml dose. Phenylalanine can be harmful if you have phenylketonuria (PKU), a rare, inherited disease that leads to the accumulation of high levels of phenylalanine in your body.
Hexyon contains less than 1 mmol (39 mg) potassium and less than 1 mmol (23 mg) sodium per dose, ie essentially ‘potassium free and ‘sodium-free.
3. How to use Hexyon
Hexyon is given to your child by a doctor or nurse who is trained in the use of vaccines and who can handle less common severe allergic reactions to the injection (see section 4. Possible side effects ).
Hexyon is given as an injection into the muscle ( intramuscular route of administration, im) in the upper part of your baby’s leg or upper arm. The vaccine is never given in a blood vessel, in or under the skin.
The recommended dose is as follows:
First vaccination series (primary vaccination)
Your child will receive either two injections given in an interval of two months or three injections given in an interval of one to two months (at least four weeks apart). This vaccine should be used according to the local vaccination program.
Additional injection (booster)
After the first series of injections, your child will receive a booster dose, according to local recommendations, at least 6 months after the last dose of one in the first vaccination series. Your doctor will tell you when this dose should be given.
If you miss a dose of Hexyon
If your child misses a scheduled injection, you must discuss it with your doctor or nurse who will decide when the missed dose should be given.
It is important to follow the instructions from the doctor or nurse so that your child completes the entire vaccination series, otherwise, your child may not have complete protection against the diseases.
If you have any further questions on the use of this vaccine, ask your doctor, pharmacist, or nurse.
