DRUG DESCRIPTION

PEDIARIX® [Diphtheria and Tetanus Toxoids and Acellular Pertussis Adsorbed, Hepatitis B (Recombinant) and Inactivated Poliovirus Vaccine Combined] is a noninfectious, sterile, multivalent vaccine for intramuscular administration manufactured by GlaxoSmithKline Biologicals. It contains diphtheria and tetanus toxoids, 3 pertussis antigens (inactivated pertussis toxin [PT] and formaldehyde-treated filamentous hemagglutinin [FHA] and pertactin [69 kiloDalton outer membrane protein]), hepatitis B surface antigen, plus poliovirus Type 1 (Mahoney), Type 2 (MEF-1), and Type 3 (Saukett). The diphtheria toxoid, tetanus toxoid, and pertussis antigens are the same as those in INFANRIX® (Diphtheria and Tetanus Toxoids and Acellular Pertussis Vaccine Adsorbed). The hepatitis B surface antigen is the same as that in ENGERIX-B® [Hepatitis B Vaccine (Recombinant)]. 

The diphtheria toxin is produced by growing Corynebacterium diphtheriae in Fenton medium containing a bovineextract. Tetanus toxin is produced by growing Clostridium tetani in a modified Latham medium derived from bovine casein. The bovine materials used in these extracts are sourced from countries which the United States Department of Agriculture (USDA) has determined neither have nor are at risk of bovine spongiform encephalopathy (BSE). Both toxins are detoxified with formaldehyde, concentrated by ultrafiltration, and purified by precipitation, dialysis, and sterile filtration. 

The 3 acellular pertussis antigens (PT, FHA, and pertactin) are isolated from Bordetella pertussis culture grown in modified Stainer-Scholte liquid medium. PT and FHA are isolated from the fermentation broth; pertactin is extracted from the cells by heat treatment and flocculation. The antigens are purified in successive chromatographic and precipitation steps. PT is detoxified using glutaraldehyde and formaldehyde. FHA and pertactin are treated with formaldehyde. 

The hepatitis B surface antigen (HBsAg) is obtained by culturing genetically engineered Saccharomyces cerevisiae cells, which carry the surface antigen gene of the hepatitis B virus, in synthetic medium. The surface antigen expressed in the S. cerevisiae cells is purified by several physiochemical steps, which include precipitation, ion exchange chromatography, and ultrafiltration. 

The inactivated poliovirus component of PEDIARIX (diphtheria, tetanus toxoids and acellular pertussis adsorbed, hepatitis b and inactivated poliovirus vaccine) is an enhanced potency component. Each of the 3 strains of poliovirus is individually grown in VERO cells, a continuous line of monkey kidney cells, cultivated on microcarriers. Calf serum and lactalbumin hydrolysate are used during VERO cell culture and/or virus culture. Calf serum is sourced from countries the USDA has determined neither have nor are at risk of BSE. After clarification, each viral suspension is purified by ultrafiltration, diafiltration, and successive chromatographic steps, and inactivated with formaldehyde. The 3 purified viral strains are then pooled to form a trivalent concentrate. 

The diphtheria, tetanus, and pertussis antigens are individually adsorbed onto aluminum hydroxide; hepatitis B component is adsorbed onto aluminum phosphate. All antigens are then diluted and combined to produce the final formulated vaccine. Each 0.5-mL dose is formulated to contain 25 Lf of diphtheria toxoid, 10 Lf of tetanus toxoid, 25 mcg of inactivated PT, 25 mcg of FHA, 8 mcg of pertactin, 10 mcg of HBsAg, 40 D-antigen Units (DU) of Type 1 poliovirus, 8 DU of Type 2 poliovirus, and 32 DU of Type 3 poliovirus. 

Diphtheria and tetanus toxoid potency is determined by measuring the amount of neutralizing antitoxin in previously immunized guinea pigs. The potency of the acellular pertussis components (inactivated PT and formaldehyde-treated FHA and pertactin) is determined by enzyme-linked immunosorbent assay (ELISA) on sera from previously immunized mice. Potency of the hepatitis B component is established by HBsAg ELISA. The potency of the inactivated poliovirus component is determined by using the D-antigen ELISA and by a poliovirus neutralizing cell culture assay on sera from previously immunized rats. 

Each 0.5-mL dose also contains 4.5 mg of NaCl and aluminum adjuvant (not more than 0.85 mg aluminum by assay). Each dose also contains   ? 100 mcg of residual formaldehyde and ? 100 mcg of polysorbate 80 (Tween 80). Neomycin sulfate and polymyxin B are used in the polio vaccine manufacturing process and may be present in the final vaccine at   ? 0.05 ng neomycin and  0.01 ng polymyxin B per dose. The procedures used to manufacture the HBsAg antigen result in a product that contains ? 5% yeast protein.  

PEDIARIX (diphtheria, tetanus toxoids and acellular pertussis adsorbed, hepatitis b and inactivated poliovirus vaccine) is formulated without preservatives. 

The vaccine must be well shaken before administration to obtain a homogeneous, turbid, white suspension. 

Diphtheria and Tetanus Toxoids Adsorbed Combined Bulk (For Further Manufacturing Use) is manufactured by Novartis Vaccines and Diagnostics GmbH & Co. KG, Marburg, Germany. The acellular pertussis antigens, the hepatitis B surface antigen, and the inactivated poliovirus antigens are manufactured by GlaxoSmithKline Biologicals, Rixensart, Belgium. Formulation, filling, testing, packaging, and release of the vaccine are performed by GlaxoSmithKline Biologicals.

What are the possible side effects of this vaccine (Pediarix)?

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...

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

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 are the possible side effects of this vaccine (Pediarix)?

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.

Get emergency medical help if your child has any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if the child has any of these serious side effects:

  • extreme drowsiness, fainting;
  • fussiness, irritability, crying for an hour or longer;
  • seizure (black-out or convulsions); or
  • high fever (can occur for up to 4 days after the vaccine).

Less serious side effects include:

  • redness, pain, tenderness, or swelling where the shot was given;
  • mild fever;
  • mild fussiness or crying;
  • joint pain, body aches;
  • loss of appetite; or
  • nausea, vomiting, diarrhea.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report vaccine side effects to the US Department of Health and Human Services at 1-800-822-7967.

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

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.

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.
