If a child receives one does of MCV4 vaccine at age 10 or older and another does...
at age less than 16, will they still need a booster does at age 16?
No. As long as the first dose was given after the 10th birthday and the 2 doses are separated by a minimum of 8 weeks. However, the child’s healthcare provider should offer a booster dose before a student graduates from high school if the student plans to attend college.
