Pediacel (DTaP-IPV-HiB)

What does the Pediacel vaccine protect against?

Pediacel is the name-brand of the vaccine that protects against diphtheria, tetanus, pertussis, poliomyelitis, and Haemophilus influenza type B (Hib) which can cause other serious diseases.

What are diphtheria, tetanus, pertussis and HiB?

Diphtheria: This is an infection of mucous membranes of the throat, nose, and skin. The infection is bacterial and can be quite serious, especially in younger infants. Diphtheria causes death in approximately 10% of all persons who contract it.

Tetanus: Tetanus, or Lockjaw, is also a bacterial infection. It is most often caused as a result of a dirt substance containing bacteria entering an open wound but this isn't always the case. The bacterium Clostridium tetani produces a toxin that affects the nervous system causing muscular stiffness, resulting in mobility issues.

Pertussis: Pertussis is also known as Whooping Cough and is caused by the bacterium Bortadella. This disease is highly contagious and greatly affects the lungs causing uncontrollable coughing fits and difficult breathing.

Haemophilus influenza type B (HiB): This bacterial infection is most commonly referred to as Hib and can cause an array of other diseases, most gravely brain infections that are potentially deadly in small children. The most common diseases Hib can cause are pneumonia, meningitis, cellulitis, otitis media (ear infection), arthritis, and other general infections throughout the body. Hib is contagious and can remain contagious even after symptoms have passed. An aggressive antibiotic treatment is used for this infection, but is not always effective.

How can these diseases spread?

Diphtheria: Diphtheria is contagious and can pass from person to person via droplets. Droplets are often a product of coughing or sneezing and contain bacterium allowing the disease to transmit.

Tetanus: This infection cannot be spread from one person to another. The Clostridium tetani bacterium must enter a wound for the tetanus infection to manifest.

Pertussis: Pertussis is highly contagious and is spread by person to person contact. There has been no definitive testing to prove that pertussis is spread by droplets, but fluids from an infected person can be transmitted by direct contact.

Haemophilus influenza type B: Hib is contagious and can remain contagious even after symptoms have passed. An aggressive antibiotic treatment is used for this infection, but is not always effective.

How safe is the Pediacel vaccine?

This vaccine is very safe. Severe side effects from Pediacel are very rare. More commonly some swelling, redness, and or mild pain can occur at the injection site. Occasionally, a child may experience a rash, fever, mild short-term loss of appetite, fussiness, or drowsiness. Acetaminophen has been shown effective in reducing these symptoms.

Your doctor can address any concerns you have relating to side effects from this vaccine. Always seek medical attention if you feel these symptoms have persisted longer than anticipated.

Call your doctor/nurse practitioner or go to the nearest hospital emergency department if your child has any of the following within three days of getting the shot:

  • high fever (over 40°C or 104 °F)
  • crying for more than three hours
  • convulsions or seizures
  • very pale colour and serious drowsiness
  • hives
  • swelling of the face or mouth
  • trouble breathing
  • other serious problems not listed

There is no risk of a pregnant woman or anyone else catching any disease from a child who has been vaccinated recently. You should always discuss the benefits and risks of any vaccine with your doctor.

How effective is the Pediacel vaccine?

When DTaP-IPV-Hib vaccine is given in the recommended number of shots, it protects over 95 per cent of children against diphtheria, virtually 100% of children against tetanus, 85% of children against pertussis, 99 per cent of children against polio and around 95% of children against serious Hib infections. It will not prevent meningitis caused by other germs."

Why is this vaccine important?

All vaccinations are important to aid in the prevention of child hood and life term diseases. Receiving Pediacel has shown to reduce hospitalizations for the associated diseases and related complications. Vaccinations have been proven to greatly reduce the severity of diseases should they be contracted in rare cases.
