The new schedule states it is permissible for doctors to recommend the earlier HPV4 vaccine for boys ages 9 and older, offering protection from four strains of the virus and reducing the likelihood of male genital warts. The recommendations also say children considered at-risk for meningococcal disease, especially those with immune-system disorders and other conditions, should get a booster shot of meningococcal conjugate vaccine, known as MCV4, three years after their initial MCV4 dose at ages 2 through 6.

The update also says that after four scheduled doses of inactivated poliovirus vaccine, the fifth dose of the same vaccine should be given on or after age 4 and at least six months after the previous dose.

Kimberlin says vaccine considerations always should consider health-care provider assessment, patient preference and the potential for adverse events. Providers who need more details should refer to the comprehensive recommendations issued by the Centers for Disease Control Advisory Committee on Immunization Practices, available by clicking here. Clinically significant adverse events that follow immunization should be reported to the Vaccine Adverse Event Reporting System at www.vaers.hhs or 800-822-7967.
