Jacobson, MDPublished Online: March 18, 2013 Abstract OBJECTIVE: To determine the reasons adolescents are not vaccinated for specific vaccines and how these reasons have changed over time. METHODS: We analyzed the 2008–2010 National Immunization Survey of Teens examining reasons parents do not have their teens immunized. Parents whose teens were not up to date (Not-UTD) for Tdap/Td and MCV4 were asked the main reason they were not vaccinated. Parents of female teens Not-UTD for human papillomavirus vaccine (HPV) were asked their intent to give HPV, and those unlikely to get HPV were asked the main reason why not. RESULTS: The most frequent reasons for not vaccinating were the same for Tdap/Td and MCV4, including “Not recommended” and “Not needed or not necessary.” For HPV, the most frequent reasons included those for the other vaccines as well as 4 others, including “Not sexually active” and “Safety concerns/Side effects.” “Safety concerns/Side effects” increased from 4.5% in 2008 to 7.7% in 2009 to 16.4% in 2010 and, in 2010, approaching the most common reason “Not Needed or Not Necessary” at 17.4% (95% CI: 15.7–19.1). Although parents report that health care professionals increasingly recommend all vaccines, including HPV, the intent to not vaccinate for HPV increased from 39.8% in 2008 to 43.9% in 2010 (OR for trend 1.08, 95% CI: 1.04–1.13). CONCLUSIONS: Despite doctors increasingly recommending adolescent vaccines, parents [...]

Vaccines plus screening could end cervical cancer

Source: www.cancernetwork.com Author: Fram Lowry Out with the old and in with the new is a commonly followed maxim in medicine given the rapid pace of developments in diagnosis and treatment. Human papillomavirus vaccines are relative newcomers to the cervical cancer armamentarium, but they cannot be relied on to do the job on their own; screening is still a must. Richard B. Roden, PhD, from Johns Hopkins University in Baltimore, and Carlos L. Santos, MD, from the Instituto Nacional de Enfermedades Neoplasicas in Lima, Peru, discussed the merits and drawbacks of HPV vaccines and standard screening during a session on female malignancies at ASCO 2009 in Orlando Long-term protection The widespread vaccination of adolescents against HPV will be critical to the eradication of cervical cancer, said Dr. Roden, an associate professor in the department of pathology. “HPV virus-like particle [VLP] vaccines are very effective in preventing genital HPV infection and neoplastic disease,” he explained. “Solid protection has been observed for more than six years after vaccination, suggesting vaccine protection is likely to be long-term, although the need for a booster is not out of the question.” To date, two HPV vaccines are FDA-approved: Gardasil from Merck, produced in yeast, and Cervarix from GlaxoSmithKline, produced in insect cells. In October 2009, Gardasil was approved by the FDA for use in boys and men (aged 9-26) for the prevention of genital warts caused by HPV-6 and HPV-11. Both vaccines target HPV-16 and HPV-18, the two most common oncogenic HPV types. Gardasil also [...]
