The CDC now recommends that all children be immunized annually for seasonal influenza. As a consequence, attention has focused recently on the magnitude of the vaccine response in young children. Recent studies have shown inadequacy of the vaccine response in children who have never received influenza vaccine (vaccine-naive). Which of the following is the approach adopted by the CDC to address this problem?

 
A. Influenza vaccine-naive children should receive two doses of vaccine for their first seasonal immunization.
B. Influenza vaccine-naive children should receive a double or triple-strength vaccine.
C. In addition to flu vaccine, give all vaccine-naive children a prophylactic antiviral medication for 6 weeks.
D. No modification of the vaccine protocol is necessary to address this minor problem.
