What is the most important information I should know about this vaccine?

The diphtheria, hepatitis B, pertussis, polio, and tetanus vaccine is given in a series of shots. The first shot is usually given when the child is 2 months old. The booster shots are then given at 4 months and 6 months of age. Your child's individual booster schedule may be different from these guidelines. Follow your doctor's instructions or the schedule recommended by the health department of the state you live in.

Be sure your child receives all recommended doses of this vaccine. If your child does not receive the full series of vaccines, he or she may not be fully protected against the disease.

Your child can still receive a vaccine if he or she has a cold or fever. In the case of a more severe illness with a fever or any type of infection, wait until the child gets better before receiving this vaccine.

Multum donot

Your child should not receive a booster vaccine if he or she had a life-threatening allergic reaction after the first shot.

Keep track of any and all side effects your child has after receiving this vaccine. When the child receives a booster dose, you will need to tell the doctor if the previous shots caused any side effects.

Becoming infected with diphtheria, hepatitis B, pertussis, polio, or tetanus is much more dangerous to your child's health than receiving the vaccine to protect against these diseases. Like any medicine, this vaccine can cause side effects, but the risk of serious side effects is extremely low.

What is diphtheria, hepatitis B, pertussis acellular, polio, and tetanus vaccine?

Diphtheria, pertussis, and tetanus are serious diseases caused by bacteria.

Diphtheria causes a thick coating in the nose, throat, and airways. It can lead to breathing problems, paralysis, heart failure, or death.

Pertussis (whooping cough) causes coughing so severe that it interferes with eating, drinking, or breathing. These spells can last for weeks and can lead to pneumonia, seizures (convulsions), brain damage, and death.

Tetanus (lockjaw) causes painful tightening of the muscles, usually all over the body. It can lead to "locking" of the jaw so the victim cannot open the mouth or swallow. Tetanus leads to death in about 1 out of 10 cases.

Hepatitis B and polio are serious diseases caused by virus.

Hepatitis B is a disease of the liver that is spread through blood or bodily fluids, sexual contact or sharing IV drug needles with an infected person, or during childbirth when the mother is infected. Hepatitis causes inflammation of the liver, vomiting, and jaundice (yellowing of the skin or eyes). Hepatitis can lead to liver cancer, cirrhosis, or death.

Polio affects the central nervous system and spinal cord. It can cause muscle weakness and paralysis. Polio is a life-threatening condition because it can paralyze the muscles that help you breathe.

Diphtheria, hepatitis B, pertussis, and polio are spread from person to person. Tetanus enters the body through a cut or wound.

The diphtheria, hepatitis B, pertussis acellular, polio, and tetanus vaccine is used to help prevent these diseases in children who are ages 6 weeks to 6 years old, before the child has reached his or her 7th birthday.

This vaccine works by exposing your child to a small dose of the bacteria or a protein from the bacteria, which causes the body to develop immunity to the disease. This vaccine will not treat an active infection that has already developed in the body.

Like any vaccine, the diphtheria, hepatitis B, pertussis acellular, polio, and tetanus vaccine may not provide protection from disease in every person.

What should I discuss with my healthcare provider before receiving this vaccine?

A hepatitis B vaccine will not protect your child against infection with hepatitis A, C, and E, or other viruses that affect the liver. It may also not protect the child from hepatitis B if he or she is already infected with the virus, even if the child does not yet show symptoms.

Multum donot

Your child should not receive this vaccine if the child is allergic to yeast, neomycin, or polymyxin B, or if the child has ever had a life-threatening allergic reaction to any vaccine containing diphtheria, hepatitis B, pertussis, polio, or tetanus.

Your child should also not receive this vaccine if he or she has:

  • severe or uncontrolled epilepsy or other seizure disorder;
  • if the child has received cancer chemotherapy or radiation treatment in the past 3 months.

Your child may not be able to receive this vaccine if he or she has ever received a similar vaccine that caused any of the following:

  • a very high fever (over 104 degrees);
  • a neurologic disorder or disease affecting the brain;
  • excessive crying for 3 hours or longer;
  • fainting or going into shock;
  • Guillain-BarrĂ© syndrome (within 6 weeks after receiving a diphtheria, tetanus, or pertussis vaccine);
  • seizure (convulsions); or
  • a severe skin reaction.

Before receiving this vaccine, tell the doctor if your child has:

  • a bleeding or blood clotting disorder such as hemophilia or easy bruising;
  • a history of seizures;
  • an allergy to latex rubber;
  • a weak immune system caused by disease or by taking certain medicines or receiving cancer treatments;
  • if the child is taking a blood thinner such as warfarin (Coumadin); or
  • if it has been less than 6 weeks since the child last received a vaccine.

Your child can still receive a vaccine if he or she has a cold or fever. In the case of a more severe illness with a fever or any type of infection, wait until the child gets better before receiving this vaccine.

How is this vaccine given?

This vaccine is given as an injection (shot) into a muscle. Your child will receive this injection in a doctor's office or other clinic setting.

The diphtheria, hepatitis B, pertussis, polio, and tetanus vaccine is given in a series of shots. The first shot is usually given when the child is 2 months old. The booster shots are then given at 4 months and 6 months of age. Your child's individual booster schedule may be different from these guidelines. Follow your doctor's instructions or the schedule recommended by the health department of the state you live in.

Your doctor may recommend treating fever and pain with an aspirin-free pain reliever such as acetaminophen (Tylenol) or ibuprofen (Motrin, Advil, and others) when the shot is given and for the next 24 hours. Follow the label directions or your doctor's instructions about how much of this medicine to give your child.
