Q: There seem to be a lot more combination vaccines now. Are they just as safe?
A: Yes. The Centers for Disease Control and Prevention (CDC) urges doctors to use these new vaccines -- which undergo additional safety and immunity studies -- to reduce the total number of shots, which also means fewer tears for your baby. Combination vaccines also make it easier for kids to get all their shots on time. In addition to the MMRV (for measles, mumps, rubella, and chickenpox) there is also a shot containing DTaP, hepatitis B, and polio. --Sandra Hume
