CDC today recommended that 11- to 12-year-olds receive two doses of
HPV vaccine at least six months apart rather than the previously
recommended three doses to protect against cancers caused by human
papillomavirus (HPV) infections. Teens and young adults who start the
series later, at ages 15 through 26 years, will continue to need three
doses of HPV vaccine to protect against cancer-causing HPV infection.
“Safe, effective, and long-lasting protection against HPV cancers
with two visits instead of three means more Americans will be protected
from cancer,” said CDC Director Tom Frieden, M.D., M.P.H. “This
recommendation will make it simpler for parents to get their children
protected in time.”
The Advisory Committee on Immunization Practices (ACIP) voted today
to recommend a 2-dose HPV vaccine schedule for young adolescents. ACIP
is a panel of experts that advises the CDC on vaccine recommendations in
the United States. CDC Director Frieden approved the committee’s
recommendations shortly after the vote. ACIP recommendations approved
by the CDC Director become agency guidelines on the date published in
the Morbidity and Mortality Weekly Report (MMWR).
CDC and ACIP made this recommendation after a thorough review of
studies over several meetings. CDC and ACIP reviewed data from clinical
trials showing two doses of HPV vaccine in younger adolescents (aged
9-14 years) produced an immune response similar or higher than the
response in young adults (aged 16-26 years) who received three doses.
Generally, preteens receive HPV vaccine at the same time as whooping
cough and meningitis vaccines. Two doses of HPV vaccine given at least
six months apart at ages 11 and 12 years will provide safe, effective,
and long-lasting protection against HPV cancers. Adolescents ages 13-14
are also able to receive HPV vaccination on the new 2-dose schedule.
CDC will provide guidance to parents, healthcare professionals, and
insurers on the change in recommendation. On October 7, 2016, the U.S.
Food and Drug Administration (FDA) approved adding a 2-dose schedule for
9-valent HPV vaccine (Gardasil® 9) for adolescents ages 9 through 14
years. CDC encourages clinicians to begin implementing the 2-dose
schedule in their practice to protect their preteen patients from HPV
cancers.
ACIP, CDC, FDA and partners monitor vaccines in use in the U.S.
year-round. These updated recommendations are an example of using the
latest available evidence to provide the best possible protection
against serious diseases.
