The annual National Immunization Survey-Teen report shows that 60% of teenagers aged 13–17 years received one or more doses of human papillomavirus (HPV) vaccine last year. That figure is a 4 percentage point increase from 2015. In addition, the report found that HPV vaccination is becoming more common among boys, with 56% of boys receiving the first dose in 2016—a 6 percentage point increase from the previous year. The rate for girls is about 65%, similar to the rate reported in 2015. Still, CDC notes there is room for improvement, as only 43% of teens are up-to-date on all the recommended doses of HPV vaccine. Furthermore, HPV vaccination rates were lower in rural and less urban areas compared with more urban areas. "I'm pleased with the progress, but too many teens are still not receiving the HPV vaccine—which leaves them vulnerable to cancers caused by HPV infection," said CDC Director Brenda Fitzgerald, MD. "We need to do more to increase the vaccination rate and protect American youth today from future cancers tomorrow." CDC last year updated its HPV vaccination recommendations to reflect evidence that two doses of HPV vaccine in younger adolescents provided similar levels of protection to those seen for three doses in older adolescents and young adults. Adolescents who receive the first dose of HPV vaccine before turning age 15 years should get two doses of HPV vaccine to be protected against cancers caused by HPV, while three doses are recommended for individuals who start the series at age 15–26 years.
