Which vaccine series generally start at age >/= 12 months for infants and children?

  1. Hep B

  2. DTaP

  3. MMR and Varicella

  4. Hib

The correct answer is: MMR and Varicella

The correct answer is C, MMR (measles, mumps, rubella) and Varicella vaccines. These vaccine series generally start at age 12 months or older for infants and children. This is because the immune system of infants and young children matures by around 12 months of age, making them better able to respond to these vaccines effectively. The MMR vaccine protects against measles, mumps, and rubella, while the Varicella vaccine protects against chickenpox. Starting these vaccines at or after 12 months ensures that children have the best immune response and protection from these diseases. Option A, Hepatitis B vaccine, is usually started at birth or soon after birth, not necessarily at age 12 months. Option B, DTaP (Diphtheria, Tetanus, acellular Pertussis) vaccine, is started in infancy, around 2 months of age. Option D, Hib (Haemophilus influenzae type b) vaccine, is usually started at 2 months of age as well.
