Which combination is listed for vaccines at 2 months and 4 months in the infant immunization schedule?

• A. DTP, OPV, and Hib
• B. DTaP, IPV, Hib, and MMR
• C. DTaP, IPV, and Hib
• D. DTP, IPV, Hib and Var

Answer: (A)

At the 2- and 4-month well visits, the infant primary series includes vaccines that protect against diseases most dangerous in early infancy: diphtheria, tetanus, pertussis, polio, and Hib. DTP (or DTaP) targets diphtheria, tetanus, and pertussis. The polio shot (IPV or OPV) protects against poliomyelitis. Hib protects against Haemophilus influenzae type b meningitis and pneumonia. These vaccines are standardly given at these early visits, often alongside others like PCV and Rotavirus, but not vaccines like MMR or Varicella, which are scheduled for later in infancy or childhood. So the combination that matches what’s listed for 2 and 4 months is DTP, OPV, and Hib.
