Menactra® should not be administered on the same day as Prevenar 13®. Studies have shown that co-administration may result in a decreased immune response to some of the pneumococcal serotypes. If both vaccines are required, Prevenar 13® should be administered first followed by Menactra® at least 4 weeks later. If these vaccines are inadvertently administered on the same day, Prevenar 13® should be repeated a minimum of 8 weeks later. Menveo® and Nimenrix® may be co-administered with Prevenar 13®.
