The primary immunization series for Pediarix is given at which ages?

• A. 2 months, 4 months, 6 months
• B. 2 weeks, 6 weeks, 8 weeks
• C. 3, 5, 7 months
• D. 1, 2, 3 months

Answer: (A)

The main idea here is the standard infant schedule for this combination vaccine. Pediarix is given as a three-dose primary series during early infancy, specifically at 2 months, 4 months, and 6 months of age. This timing aligns with how subsequent DTaP-containing vaccines are arranged and keeps protection established early in life. Why the other options don’t fit: doses at 2 weeks, 6 weeks, and 8 weeks occur too early for this product’s approved infant schedule. Doses at 3, 5, 7 months or at 1, 2, 3 months don’t match the established primary series timing for Pediarix, which starts at 2 months and is completed by 6 months.
