Indications & Clinical Uses

Infanrix Tetra is a combination vaccine that targets several bacterial and viral agents responsible for serious childhood diseases.

  • Diphtheria: stimulates protective antibodies that neutralize diphtheria toxin.
  • Tetanus: induces immunity against tetanus neurotoxin.
  • Pertussis: generates antibodies to prevent whooping cough.
  • Poliomyelitis: provides immunity to all three poliovirus serotypes.
  • Haemophilus influenzae type b: creates antibodies against the capsular polysaccharide, preventing invasive Hib disease.

How It Works

  • Infanrix Tetra contains diphtheria and tetanus toxoids, acellular pertussis antigens, inactivated poliovirus, and Hib polysaccharide, each adsorbed onto aluminium hydroxide. After intramuscular injection, the antigens are taken up by antigen‑presenting cells, processed, and displayed to T cells, prompting B‑cell activation and the production of specific IgG antibodies that neutralize the respective toxins and pathogens, establishing active immunity.

Side Effects

Common Side Effects

  • Pain, redness or swelling at the injection site.
  • Low‑grade fever within 24‑48 hours.
  • Irritability or fussiness in infants.
  • Reduced appetite.
  • Mild headache.
  • Transient rash.

Serious or Rare Side Effects

  • Anaphylactic reaction (severe allergy).
  • Seizures or high‑grade fever.
  • Prolonged crying episodes.
  • Hypotonic‑hyporesponsive episodes.
  • Encephalopathy (extremely rare).
  • Persistent neurological symptoms.

Precautions & Warnings

Infanrix Tetra should be administered according to national immunization schedules and under professional supervision.

  • Allergy: Do not give to individuals with a known severe allergy to any vaccine component.
  • Acute illness: Postpone vaccination if the child has a moderate or severe febrile illness.
  • History of seizures: Monitor closely in children with prior seizure disorders.
  • Immunocompromised: Evaluate risk‑benefit before vaccinating severely immunocompromised patients.
  • Previous severe reaction: Avoid repeat dosing if a serious adverse event occurred after a prior dose.
  • Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Avoid Interactions

Infanrix Tetra may interact with other vaccines or immune‑modulating agents.

Major Interactions (Avoid)

  • Concurrent administration of live attenuated vaccines may reduce efficacy of either product.
  • Immunoglobulin or blood products given shortly before or after vaccination can diminish the immune response.
  • Severe allergic reaction to a previous dose of any component.

Moderate Interactions (Monitor Closely)

  • Antipyretics (e.g., acetaminophen) may mask fever, a sign of reaction.
  • Systemic corticosteroids may blunt antibody production.
  • Concurrent use of other inactivated vaccines may increase local reactogenicity.

Frequently Asked Questions

Infanrix Tetra is a combination vaccine used to immunize infants and young children against diphtheria, tetanus, pertussis (whooping cough), poliomyelitis and Haemophilus influenzae type b disease. It is administered as part of routine childhood immunization schedules in many countries.

The vaccine contains toxoids and inactivated antigens that are adsorbed onto aluminium hydroxide. After intramuscular injection, these components stimulate the immune system to produce specific antibodies, providing active protection against the bacterial toxins and viral particles included in the formulation.

The dosage and schedule of Infanrix Tetra are determined by the prescribing health professional based on national immunization guidelines. The prescriber decides the number of doses, timing between doses, and the appropriate age for administration.

Infanrix Tetra is generally not administered to pregnant women because it is intended for infants. Breastfeeding mothers may receive the vaccine if indicated for their child, but they should discuss any concerns with their healthcare provider to ensure safety for both mother and infant.

To place an order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, cold‑chain shipping details and necessary import documentation.

Infanrix Tetra combines five antigens (DTaP, IPV and Hib) in a single injection, reducing the number of visits compared with separate vaccines. Alternative products may contain similar antigens but differ in adjuvant type, antigen concentrations, or licensing region, which can affect reactogenicity and schedule flexibility.

The vaccine must be stored refrigerated at 2‑8 °C, protected from light, and must never be frozen or shaken. It should be kept in its original packaging until use to maintain potency and stability throughout the supply chain.

Infanrix Tetra is given by a single intramuscular injection, typically into the anterolateral thigh of infants or the deltoid muscle of older children, according to the schedule recommended by health authorities.

Serious adverse events are rare but can include anaphylaxis, seizures, high‑grade fever, and neurologic complications such as encephalopathy. Any signs of severe allergic reaction or neurologic symptoms after vaccination should prompt immediate medical evaluation.

Infanrix Tetra should not be given to individuals with a documented severe allergy to any vaccine component, those who have experienced a serious reaction to a previous dose, or children with certain severe immunodeficiencies unless specifically advised by a specialist.
