Are combination vaccines safe?

Some parents may have concerns about vaccinating their children with combination vaccines designed to protect against multiple diseases with a single injection.24 Combination vaccines have been studied extensively and have shown to be safe and effective in preventing disease.24 Vaccines, including those in combination, work to strengthen the immune system by causing the body to fight against the antigens they contain.24 There is much less risk of complications with vaccines than the actual infection or disease itself.24

Indication
Pentacel vaccine is indicated for active immunization against diphtheria, tetanus, pertussis, poliomyelitis, and invasive disease due to Haemophilus influenzae type b. Pentacel vaccine is approved for use as a 4-dose series in children 6 weeks through 4 years of age (prior to fifth birthday).

Safety Information
The most common local and systemic adverse reactions to Pentacel vaccine include injection site redness, swelling, and tenderness; fever, fussiness, and crying. Other adverse reactions may occur. Known systemic hypersensitivity reaction to any component of Pentacel vaccine or a life-threatening reaction after previous administration of the vaccine or a vaccine containing the same substances are contraindications to vaccination.

The decision to give Pentacel vaccine should be based on the potential benefits and risks; if Guillain-Barré syndrome has occurred within 6 weeks of receipt of a prior vaccine containing tetanus toxoid; or if adverse events have occurred in temporal relation to receipt of pertussis-containing vaccine. Encephalopathy within 7 days of administration of a previous dose of a pertussis-containing vaccine or a progressive neurologic disorder is a contraindication. Vaccination with Pentacel vaccine may not protect all individuals.

Before administering Pentacel vaccine, please see the full Prescribing Information.

Pentacel vaccine is manufactured by Sanofi Pasteur Limited and Sanofi Pasteur SA and distributed by Sanofi Pasteur Inc.
