Which immunizations are routinely given at birth and at 2 months?

• A. Birth: Hepatitis B; 2 months: DTaP, Hib, IPV, PCV, Rotavirus
• B. Birth: Hepatitis A; 2 months: MMR, Varicella, DTaP, Hib
• C. Birth: Tetanus only; 2 months: DTaP, Hib, IPV, PCV
• D. Birth: Hepatitis B; 2 months: DTaP, Hib, IPV, PCV, Rotavirus (Hep B may be given at birth or later if not given).

Answer: (D)

The main concept is understanding the routine vaccination timeline in early infancy. A birth dose of hepatitis B is given right after birth to start protection early. Then, at about the two-month visit, a standard set of vaccines is given together to establish protection against several diseases: DTaP (diphtheria, tetanus, pertussis), Hib (Haemophilus influenzae type b), IPV (inactivated polio vaccine), PCV (pneumococcal), and Rotavirus (an oral vaccine). Hepatitis B may be given at birth or deferred to a later visit if it wasn’t given at birth, but the birth dose is the usual starting point. This is why the description that lists birth hepatitis B and the two-month combination of DTaP, Hib, IPV, PCV, and Rotavirus best matches the routine schedule. Other options cite vaccines that aren’t routinely given at birth or at the two-month mark (for example Hepatitis A, MMR, Varicella at these times, or a birth-only tetanus).
