Which immunization is NOT recommended for 11 to 12-year-olds?

The measles, mumps, and rubella (MMR) vaccine is typically administered to children in a different set of age categories, usually given in two doses—first between 12 and 15 months of age and again between 4 and 6 years of age. By the time children reach 11 to 12 years old, they are generally due for booster shots of other vaccines that are more pertinent to adolescent health needs. While MMR is certainly crucial in early childhood vaccination schedules, it is not required at the time when children are transitioning into their teenage years.

In contrast, the meningococcal conjugate vaccine (MCV4), tetanus, diphtheria, and pertussis (TDAP) booster, and the human papillomavirus (HPV) vaccine are all recommended at this age to help protect against diseases that affect adolescents and young adults. Therefore, the MMR vaccine does not fit the recommended immunization schedule for 11 to 12-year-olds in the same way these other vaccines do.
