addresses N. meningitidis serogroups A, C, Y and W-135, which
account for nearly 80 percent of adolescent cases of meningococcal
meningitis or bloodstream infections.
This
vaccine has several advantages over previous versions of the
meningococcal vaccine including booster responses (memory), herd
immunity if enough adolescents are immunized and possibly
elimination of the carrier state.
The Center for Disease Control
(CDC) currently recommends immunizing all 11 to 18 year olds,
entering college freshmen planning to live in dormitories and
specific groups at increased risk of acquiring this disease.
High-risk adolescents, including those with functional asplenia and
persistent complement deficiency, who have received the vaccine in
the past should have a second MCV4 vaccine 5 years after the first.
The
MCV4 vaccine, unlike the earlier polysaccharide version of the
vaccine, requires an intramuscular injection.

Tetanus, diphtheria and acellular pertussis (Tdap)
vaccine was licensed by the United States Federal Drug
Administration (FDA) in 2005. Since 2000, the number of cases of
pertussis (whooping cough) has increased to epidemic proportions in
people 10 to 19 years old. This is due to waning immunity that
occurs 5 to 8 years after childhood immunization and also
after natural infection. Experts estimate there are nearly 1 million
cases of pertussis each year in the United States. Not only does
this disease pose a threat to the health of adolescents and older
adults, but it also puts the lives of partially immunized or
unimmunized infants at risk.
The CDC
has recommended that all adolescents 11 to 12 years old routinely
receive the Tdap vaccine.
Further, adolescents 13-18 years old who have not previously had the
vaccine should receive it as soon as possible . A 5-year interval
between other diphtheria and tetanus containing products and Tdap is
encouraged for adolescents unless the benefit of vaccination (ex.
high pertussis rates in an area) exceeds the risk of local reaction.

which prevents
cervical cancer, is the second vaccine that
prevents cancer. The hepatitis
B vaccine, which prevents liver cancer, was the first.
HPV is a virus that can affect the genital area of
the body. “Low-risk” types, including types 6 and 11, account for approximately 90 percent of genital warts, and
“high-risk” oncogenic types can cause cervical, vulvar, vaginal,
anal and penile cancer. Types 16 and 18 HPV account for
approximately 70 percent of all cervical cancer cases.
There are currently 2 HPV vaccines. The quadrivalent
vaccine protects against 4 types of the virus: HPV
types 16 and 18
that are known to cause cervical cancer in women as well
as other types of cancer in both men and women, and HPV
types 6 and 11
which cause external genital lesions in both men and women. The
bivalent vaccine protects against 2 types of the virus:
HPV 16 and 18.
The vaccines are
preventive and not therapeutic, thus they are most effective when
administered before exposure to HPV via sexual contact. However, the
vaccines are also recommended for females 11 to 26 years old who have
had sexual contact, have had positive PAP tests or who have evidence
of prior HPV infection. Both HPV vaccines are recommended for adolescent females age 11 to 12 years of age (with administration at
9 to 10 years of age if preferred) and for those age 13 to 26 years
who have not previously received vaccination. The quadrivalent
vaccine can be given to males ages 11-26 who are interested in
preventing HPV. Research regarding
efficacy among males and women older than age 26 years is ongoing.

is recommended for several populations. At the end of June 2006, a
second dose of varicella was recommended for all children,
adolescents and young adults who have previously received only one
dose and have no evidence of having had the disease. A second dose
will decrease the risk of break-through disease and associated
school absence, missed work and potential medical complications
associated with the chickenpox.
The
MMRV
vaccine (combination of measles, mumps, rubella and varicella) is
not licensed for use in those 13 years of age or older, so if both
MMR
and varicella are required above the age of 13 years, separate
vaccines (given on the same day at different anatomic sites) are
recommended.

Additional vaccines are recommended for
special populations of adolescents requiring
hepatitis A,
prenemococcal vaccines, and for
adolescents requiring “catch-up” with
inactivated polio or
hepatitis B vaccines.
