Are the three MenACWY vaccines interchangeable?

Menactra (MenACWY-D) is not approved for children younger than 9 months so only the Menveo two-vial formulation requiring reconstitution (MenACWY-CRM) should be used for children age 2 through 8 months. MenQuadfi (MenACWY-TT) is not approved for children younger than age 2 years. The one-vial formulation of Menveo that does not require reconstitution is approved for children and adults age 10 through 55 years. When more than one brand is age-appropriate, the vaccines are interchangeable.
