If Menactra is given to an infant instead of pneumococcal conjugate vaccine, what do I do?
Menactra is not licensed for infants so of course this dose is invalid. It does not provide any protection from Pneumococcus, so you need to give a dose of Pneumococcal conjugate vaccine. This can be given immediately, with no need for spacing, because Menactra and pneumococcal conjugate vaccine are two separate inactivated vaccines.
