Bexsero (MenB) is two doses given 4 weeks apart. For children receiving their first vaccines for the flu (whether inactivated or live), it is recommended they receive two doses 4 weeks apart. Lots of the early childhood vaccines have minimum spacings of 4 weeks, but are given at 2, 4, and 6 months simply because of standard pediatric followup visit schedules: DTaP, Hib, IPV, PCV13, and Rotavirus. HepB has a first dose at birth and the second at 4 weeks -- 2 months. HPV is available in a 3-dose series with 4 weeks between the first two doses.
