Warnings and Precautions
General: Do not administer intravascularly or intradermally. Protective immune response may not be elicited in all vaccinees.
Injection Precautions: Administer deep intramuscularly at a different site for each injection. Epinephrine should be available for immediate use in case of anaphylactic reactions.
Hematologic: Caution in subjects with thrombocytopenia or a bleeding disorder.
Immune Response: May be diminished in immunosuppressed individuals.
Neurologic: Defer pertussis vaccination in children with progressive neurological disorders until stabilized.
Adverse Reactions
Common: Loss of appetite, irritability, abnormal crying, restlessness, pain, redness, swelling at the injection site, fever >38°C, fatigue.
Uncommon: Upper respiratory tract infection, somnolence, cough, diffuse swelling of the injected limb.

Clinical Trials and Efficacy
Immunogenicity: High immune response rates for all antigens after 3-dose and 2-dose primary vaccination schedules, with robust antibody responses observed in clinical studies.
Protective Efficacy: Demonstrated high efficacy in preventing pertussis, diphtheria, tetanus, hepatitis B, poliomyelitis, and Hib disease.
Persistence of Immune Response: Protective immunity against hepatitis B, poliovirus, and Hib persisted in children 4-8 years after vaccination.
