Which vaccine is typically administered at 2 months of age?

• A. MMR
• B. DTaP
• C. HepA
• D. Varicella

Answer: (B)

The main idea here is understanding when vaccines are started in the infant schedule. At about 2 months, the primary series of several vaccines begins to establish early protection, because infancy is a high-risk period for these diseases and the immune system can safely respond to multiple vaccines at once. DTaP is given at 2 months as part of this early start. It protects against diphtheria, tetanus, and pertussis, and is formulated for safe use in young infants. This timing—initial doses at 2, 4, and 6 months—is designed to build immunity early before children are more likely to be exposed. In contrast, MMR and Varicella are vaccines that are not started until after the first birthday, and Hepatitis A is typically started around 12 months. While HepB can be given around 1–2 months as part of the birth-to-early infancy plan, the vaccine most classically associated with the 2-month visit for initiating the infant’s primary series is DTaP.
