Problem: Scott is a 2½-year-old with chronic lung disease caused by premature birth and his healthy 4-year-old sister, Isabelle, are in the office today (November) for well-childcare visits. Their father has congenital IgA deficiency but is otherwise healthy. Their mother is healthy. None of the family has had influenza vaccine previously except for the 66-year-old grandfather who lives with the family.
1. Is influenza vaccine recommended for any family members?
2. Given that Scott and Isabelle have never received influenza vaccine, if they were to be vaccinated, how many doses would be needed? What type of vaccine can each receive?
3. Can influenza vaccine be administered simultaneously with other vaccines?
