A mother brings her 19 month old son in for influenza vaccination. He received only one dose of inactivated quadrivalent vaccine last October. Which of the following is the most appropriate choice for vaccination at this time?
A) A single dose of inactivated quadrivalent vaccine
B) Two doses of inactivated quadrivalent vaccine given 4 or more weeks apart
C) Two doses of intranasal live attenuated vaccine given 4 or more weeks apart
B - children 6 to 8 months old who have not received at least 2 lifetime doses of the trivalent or quadrivalent vaccine before July should receive 2 doses at least 4 weeks apart. They should receive their first dose as soon as possible after the vaccine becomes available so that the second dose can be administered by the end of October. Because this patient is <2 years old, he should receive an inactivated vaccine.
