When quadrivalent meningococcal conjugate vaccine was first recommended for preteens and teens in 2005, the expectation was that protection would last for 10 years; however, currently available data suggest protection declines in most teens within 5 years.ll 11â12 year olds should be vaccinated with a quadrivalent (protects against serogroups A, C, W, and Y) meningococcal conjugate vaccine (MenactraÂ® or MenveoÂ®). A booster dose is recommended at age 16 years.
