4 doses are administered before age 4 years, an additional (fifth) dose
should be administered at age 4 through 6 years .
- The hepatitis A footnote has been revised to allow
vaccination of children older than 23 months for whom immunity against
hepatitis A is desired.
- Revaccination with meningococcal conjugate vaccine is
now recommended for children who remain at increased risk for
meningococcal disease after 3 years (if the first dose was administered
at age 2 through 6 years), or after 5 years (if the first dose was
administered at age 7 years or older) .
- Footnotes for human papillomavirus (HPV) vaccine have
been modified to include 1) the availability of and recommendations for
