Aiden is a 6-month-old healthy boy. What vaccination should he receive for influenza?

Aiden, being a healthy 6-month-old, falls within the recommendations for influenza vaccination. The correct answer indicates that he should receive a dose of inactivated influenza vaccine (IIV4), which is appropriate for his age.

At 6 months, infants are eligible to begin receiving the influenza vaccine. The current guidelines recommend that children younger than 9 years who are receiving the vaccine for the first time receive two doses. The first dose is administered, followed by a second dose given at least 4 weeks later to ensure sufficient immune response and protection against the influenza virus.

The option suggesting that Aiden is too young does not account for updated guidelines allowing influenza vaccination starting at 6 months. The proposition of using live attenuated influenza vaccine (LAIV) is not suitable for this age group, as LAIV is typically not recommended for children under 2 years of age. The option suggesting one dose followed by a second dose in a year could mislead caregivers, as the timing between doses should be shorter to build immunity effectively, especially when it involves initial vaccination for those under 9 years of age. Hence, option B is the correct choice for Aiden's influenza vaccination.
