Combination vaccines have been used since the mid-1940s. They have been used for many years without evidence of adverse effects and just as effectively as giving them separately.

There are a few exceptions. The most notable is the MMRV: measles, mumps, rubella, and varicella all in one. Febrile seizures can occur more frequently with a combination MMRV than when MMR and V are given as separate injections.
