HPV Vaccine Reduces All Subtypes of HPV Disease

Source: Medscape.com Human papillomavirus (HPV) vaccination substantially reduced the risk for subsequent HPV disease in women who already had 1 bout of HPV-related disease, according to a study published online today in BMJ. "These are, to our knowledge, the first results in vaccinated women who have undergone treatment for HPV-related disease," write the authors, headed by Elmar Joura, MD, from the Medical University of Vienna in Austria. The data come from a subgroup of women who participated in trials of the quadrivalent HPV vaccine Gardasil (Merck & Co). Women who had HPV infection at the time of vaccination and who developed cervical, vulvar, or vaginal HPV disease had a substantially reduced risk of developing subsequent HPV-related disease after the first definitive treatment. HPV vaccination substantially reduced the risk for subsequent HPV disease — not only that caused by the 4 viral strains in the quadrivalent vaccine (HPV subtypes 6, 11, 16, and 18), but also that caused by other strains of HPV-related disease. This study "reinforces much of what we already know about the protective properties of the quadrivalent vaccine, including cross-protection against nonvaccine HPV types and vaccine benefit despite HPV exposure," writes Jane Kim, assistant professor of health decision science at Harvard School of Public Health, Boston, Massachusetts, in an accompanying editorial. Subgroup of Women The study analyzed data collected from 2 large company-sponsored placebo-controlled trials of Gardasil, known as FUTURE I and FUTURE II. Together, they involved 17,622 women 15 to 26 years of age who were randomized to receive [...]

AAP Now Recommends HPV Vaccine for Boys and Girls

Source: HemOnc Today The American Academy of Pediatrics Committee on Infectious Diseases issued an updated policy statement on human papillomavirus vaccination that recommends both boys and girls be immunized. The policy statement notes vaccination reduces the incidence of sexually transmitted infections and reduces cancer risk. “Persistent infection with high-risk HPV types is responsible for most cervical and anal cancers in females,” the statement reads. “In males, high-risk HPV types are responsible for a large proportion of cancers of the mouth and pharynx, which are increasing in recent years, and of anal and penile cancers.” There currently is one approved HPV vaccine (HPV4; Gardasil, Merck) for boys and two vaccines — HPV4 and HPV2 (Cervarix, GlaxoSmithKline) — approved for girls. The committee recommended that: Girls aged 11 to 12 years should receive three doses of HPV2 or HPV4 — administered intramuscularly at 0, 1 to 2, and 6 months — even if they already are sexually active. Boys aged 11 to 12 years should receive three doses of HPV4 using the same schedule. Females aged 13 to 26 years and males aged 13 to 21 years who were not previously immunized or who are missing a vaccination should complete the full series. Men aged 22 to 26 years who were not immunized previously or who are missing a vaccination may receive the HPV4 series, but “cost-efficacy models do not justify a stronger recommendation in this age group.” The policy statement recommended that women who receive the vaccine continue to undergo cervical [...]

HPV exposure increases men’s risk of cancer

Source: http://news.medill.northwestern.edu/ Author: Zen Vuong “We’re at the precipice of this epidemic,” said Dr. Ezra Cohen, who specializes in head and neck cancers. The culprit is sexually-transmitted human papillomavirus-16. Human papillomavirus-positive head and neck cancer cases have been rising about 3 percent every year for the last three decades, said Cohen of The University of Chicago Medicine, an institution that includes the University of Chicago Hospitals. HPV-16 infection is three times more likely in men than in women, he added. Cells of the upper respiratory system of both men and women are very similar to the surface of the cervix in women, said Dr. Kenneth Alexander, chief of infectious diseases at The University of Chicago Medicine. HPV is linked to cervical cancer as well. The Centers for Disease Control and Prevention estimates 10,800 new cases of HPV-associated cervical cancer in the United States each year. This number is nearly 35 percent larger than the 7,100 cases of HPV-associated head and neck cancers found in the United States each year. Oral sex is “probably the most important risk factor” in contracting HPV-16-related head and neck cancer, which “will become more common than cervical cancer in this decade,” he added. Some 5,600 men are diagnosed with HPV-associated head and neck cancers each year, whereas only 1,500 women suffer the same fate, according to the CDC. HPV-16, one of more than 150 strains, is a sexually transmitted condition. More than 40 HPV types can be sexually transmitted, according to the National Cancer Institute. [...]

HPV Vaccine Not Linked To Autoimmune Disorders, Study

Source: MedicalNewsToday.com A two-year study of nearly 190,000 girls and women, finds that Gardasil, the human papillomavirus (HPV) vaccine made by Merck & Co, does not trigger autoimmune disorders such as lupus, rheumatoid arthritis, type 1 diabetes and multiple sclerosis. The results are published in the Journal of Internal Medicine. Study lead author Dr Chun Chao, a research scientist at the Kaiser Permanente Department of Research & Evaluation in Pasadena, California, said in a statement released on Friday, that: "This kind of safety information may help parents with vaccination decisions." ""These findings offer some assurance that among a large and generalizable female population, no safety signal for autoimmune conditions was found following HPV4 vaccination in routine clinical use," said Chao. Gardasil is a "quadrivalent" vaccine because it helps protect against 4 types of HPV. In girls and young women age 9 to 26, it targets 2 types that cause about 75% of cervical cancers, and 2 other types that cause 90% of cases of genital warts. The vaccine, which is given as three injections over six months, also helps protect boys and men age 9 to 26 against 90% of cases of genital warts. Genital warts is the most common sexually transmitted infection in the US, where it infects about 6.2 million people every year. It can also lead to cervical cancer in women. Gardasil received US Food and Drug Administration (FDA) approval in 2006. But a longstanding concern about links with autoimmune disorders has surrounded the vaccine, and many [...]

Success of HPV vaccination is now a matter of coverage

Source: The Lancet Oncology, Volume 13, Issue 1, Pages 10-12, January 2012 In a pair of articles in The Lancet Oncology, Lehtinen and colleagues and Wheeler and colleagues present 4-year end of study data from a trial of a prophylactic human papillomavirus (HPV)-16/-18 vaccine (Cervarix, GlaxoSmithKline) in young women aged 15-25 years. From a public-health perspective, these studies have several important contributions. The results assure us that among HPV-naive women in the 15—25 year age range, Cervarix has extremely high efficacy against HPV-16/-18-associated persistent infection, CIN2, and CIN3 or worse, the best ethical surrogate endpoint for prospective studies of invasive cervical cancer risk. Combined with other trials of Cervarix and Merck's quadrivalent Gardasil vaccine against HPV-16/-18/-6/-11,3 the evidence is strong for near 100% prophylactic vaccine efficacy in HPV-naive women at any age. Nonetheless, even with vaccine efficacy near 100% in HPV-naive women, the efficacy in the total vaccinated cohort decreased steeply with increasing age, showing an absence of therapeutic effect against already-acquired infections and associated lesions. We know from natural history studies that new HPV transmission (incidence, not prevalence) decreases with age in most cultures.4 Together, natural history data and results of trials for both vaccines suggest that vaccination before sexual debut, or around the time of menarche, will achieve the greatest reduction in cervical cancer rates. The 4-year trial data shows no decline in vaccine efficacy in HPV-naive women with time since vaccination.1 We know from other trials of the two vaccines that the duration of protection is several [...]

Boys need the cervical cancer jab, too

Source: www.telegraph.co.uk Author: Max Pemberton Few politicians will ever admit they are wrong, so I salute health ministers who have finally capitulated to medical opinion and last month announced a U-turn on the cervical cancer vaccine that is given to 12- and 13-year-old girls. Until now, Cervarix, which protects against two strains of the human papilloma virus (HPV) that are a factor in at least 70 per cent of diagnoses, has been the NHS vaccine of choice. However, another vaccine, Gardasil, also protects against a further two strains of HPV which cause genital warts, the most common sexually-transmitted infection, requiring costly and unpleasant treatment. As doctors have been arguing for some time, this has important public health implications. The current cost to the NHS of treating the 100,000 new cases of genital warts in England each year is £23 million. In several countries, including Australia, where Gardasil has been used in nationwide vaccination programmes, a 75 per cent decrease in the number of new cases of genital warts in the past three years has been reported. Critics of NHS policy complained that Cervarix was chosen over Gardasil not on the basis of clinical efficacy but because its manufacturers offered it at a discounted price, making it the most cost-effective. Indeed, many doctors have admitted in the medical press that they have bought Gardasil for their daughters privately, while they had to give their patients Cervarix. But ministers have seen sense as now Gardasil will be available on the NHS. But the [...]

HPV vaccine myths put health, lives at risk, say health leaders: Airing the facts

Source: TheNationsHealth.org Vaccination rates for human papillomavirus are lagging for teens, and a complicated web of confusion and misinformation may be to blame, according to public health leaders. Several strains of HPV can cause cervical cancer, and two vaccines, Gardasil and Cervarix, have been shown conclusively to defend against those strains. The Food and Drug Administration recommended in 2006 that girls receive the vaccine before they become sexually active so that they are protected at the outset. In 2009, FDA approved the use of the vaccine for boys as well. According to the Centers for Disease Control and Prevention, about 6 million people in the U.S. become infected with HPV each year and each year about 12,000 women are diagnosed with cervical cancer, leading to about 4,000 deaths. Studies have shown the vaccine to be overwhelmingly safe, CDC said. As of June 2011, about 35 million doses of Gardasil had been distributed in the United States. CDC’s adverse event tracking mechanisms reported about 18,000 adverse events, 92 percent of which were nonserious events, such as fainting, swelling at the injection site and headache. Sixty-eight deaths were reported, but there is “no unusual pattern or clustering to the deaths that would suggest that they were caused by the vaccine, and some reports indicated a cause of death unrelated to vaccination,” CDC said. And yet, fed perhaps by misinformation or squeamishness about the idea of their children becoming sexually active, some parents are opting not to vaccinate, and the vaccination rates are [...]

Use and Acceptance of HPV Vaccine Still a Work in Progress

Source: National Cancer Institute A bellwether moment in the history of cancer prevention came in 2006 when the Food and Drug Administration (FDA) approved the first vaccine to prevent cervical cancer. The vaccine, Gardasil, protects against the two primary cancer-causing, or oncogenic, types of the human papillomavirus (HPV)—HPV-16 and HPV-18. These types are responsible for more than 70 percent of cervical cancer cases worldwide. In 2009, the FDA approved a second HPV vaccine, Cervarix, which also targets HPV-16 and HPV-18. Gardasil and Cervarix, vaccines that protect against the two primary cancer-causing types of the human papillomavirus (HPV), entail a three-shot regimen, with each dose delivered several months apart. But what has transpired since these two vaccines received regulatory blessing in the United States has reaffirmed something that cancer and public health researchers have appreciated for some time: The translation of basic research to the clinic doesn’t end with FDA approval of a new drug or treatment. In many respects, FDA approval is just a beginning. In March 2007, the CDC’s Advisory Committee on Immunization Practices (ACIP) gave its strongest recommendation for HPV vaccination for females ages 9 to 26, which is the FDA-approved indication for Gardasil. Cervarix is approved for females ages 10 to 25. Both vaccines entail a three-shot regimen, with the doses delivered several months apart. According to the most recent data, only 44 percent of adolescent girls 13 to 17 years of age have received at least one dose of the vaccine. Completion rates for the three-shot [...]

HPV Vaccine Recommended for Boys aged 11 to 12 Years

Source: HemOncToday.com The CDC's Advisory Committee on Immunization Practices today approved routine recommendation in favor of administering the quadrivalent HPV vaccine for boys aged 11 to 12 years. Committee members decided that the vaccine (Gardasil, Merck) was safe, efficacious and cost-effective enough to warrant routine usage in this population. The recommendation issued in 2009 was permissive, meaning providers could give the vaccine to boys, but it was not routinely administered. This change would put the HPV vaccine into the regular vaccination schedule. The three-vaccination series can start as early as age 9 years. "The committee recommended that routine vaccination of males aged 11 or 12 years with three doses of quadrivalent vaccine be given to prevent HPV infection and HPV-related disease," Anne Schuchat, MD, director of the CDC's National Center for Immunization and Respiratory Diseases, said in a phone call with reporters. "Boys and young men 13 to 21 years of age who have not already received the vaccine should be vaccinated." Anne Schuchat, MD Insurance companies typically cover HPV vaccine in boys, but that is not necessarily the case for a permissive recommendation, according to Schuchat, who said a routine recommendation for a vaccine usually translates into coverage without co-pays. The committee voted 8-5 with one abstention in favor of recommending vaccination for young men up to age 21 years with permissive recommendation for men aged 22 to 26 years. The committee considered recommending vaccination up to age 26 years, which would have harmonized recommendations for men and women, [...]

CDC Committee Recommends Boys Receive HPV Vaccine

Source: CNN.com A federal government advisory committee voted Tuesday to recommend that boys and young men, from ages 11 to 21, be vaccinated against the human papilloma virus, commonly referred to as HPV. The Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices says the vaccine series can be started as early as age 9. Twelve members of the committee voted in favor of a recommendation that 11- and 12-year-old boys be vaccinated; one member abstained. A separate vote involving males age 13 to 21 was split. Eight voted for it; five voted against, and one abstained. The same recommendation said males age 22 through 26 may be vaccinated. HPV is the No. 1 sexually transmitted disease in the United States. At least 50% of sexually active people will get it at some point in their lives. Study: Males should get HPV vaccine too The HPV votes took place as part of the advisory committee's meeting in Atlanta, Georgia. The HPV vaccine is already recommended for females between the ages of 9 and 26 to reduce the risk of cervical cancer. The CDC recommends girls get the vaccine at age 11 or 12. The FDA approved the first HPV vaccine, Gardasil, back in 2006. The second vaccine, Cervarix, was approved in 2009. The vaccine is given in three doses. Gardasil also protects against most genital warts and has been shown to protect against anal, vaginal and vulvar cancers, all of which are associated with HPV, according to the [...]
