One HPV Vaccine Dose May Be As Effective As Multiple, Study Finds

BOSTON (CBS) — It is currently recommended that boys and girls under age 15 get two doses of the human papillomavirus (HPV) vaccine but a new study published in the journal Cancer finds that just one dose may be as effective. HPV is the most common sexually transmitted infection and certain strains of the virus are associated with cervical cancer in women. Researchers at the University of Texas looked at more than 130,000 females and found that one dose of the HPV vaccine was as effective as multiple doses for preventing cervical changes that often lead to cervical cancer. The hope is that if only one dose is required, even more kids will get vaccinated.

Human papillomavirus (HPV) is the most common sexually transmitted virus. The high-risk HPV types (i.e., HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59) are considered to be the main etiological agents of genital tract cancers, such as cervical, vulvar, vaginal, penile, and anal cancers, and of a subset of head and neck cancers. Three prophylactic HPV vaccines are available that are bivalent (vs. HPV16, 18), tetravalent (vs. HPV6, 11, 16, 18), and non-avalent (vs. HPV6, 11, 16, 18, 31, 33,45, 52, 58). All of these vaccines are based on recombinant DNA technology, and they are prepared from the purified L1 protein that s...

Abstract HPV is still the most common sexually transmitted infection, leading to the onset of many disorders while causing an increase in direct and indirect health costs. High Risk (HR) HPV is the primary cause of invasive cervical cancer and contributes significantly to the development of anogenital and oropharyngeal cancers. The introduction of universal HPV vaccination has led to a significant reduction in vaccine-targeted HPV infections, cross-protective genotypes, precancerous lesions and anogenital warts. Despite the several limitations of HPV vaccination programs, including vaccine type specificity, differ...

Conclusions Vaginal-receptive penile sex in the last 12 months was associated with a 5-fold increased odds of cervical high-risk HPV infection among TM. Findings can inform future population level study of associations between sexual behaviors and hr-HPV risk, which could lead to more individualized approaches to screening.

AbstractIn the U.S. there is an epidemic of sexually transmitted diseases (STIs). One of the most prevalent STIs is the Human Papillomavirus (HPV). Certain high risk strains of HPV are believed to cause virtually all cervical cancers, over 90% of anal cancers, 70% of oropharyngeal cancers, and the majority of anal  genital warts. HPV is preventable through vaccination and is available for both men and women. Several educational interventions have been employed, yet baseline awareness and knowledge related to HPV and 9vHPV remains relatively low among young men. What is not known is the most effective method for provid...

For its first few years on the market, the human papillomavirus (HPV) vaccine was approved only for young girls. Over time, the U.S. Food and Drug Administration (FDA) has broadened its approval to include boys, as well as adults up to age 45—allowing more people to get the cancer-preventing vaccine, but also breeding confusion about who should get vaccinated and when. On Thursday, the U.S. Centers for Disease Control and Prevention (CDC) released new recommendations, based on guidance from the Advisory Committee on Immunization Practices, that should clear up some of that confusion. The CDC reaffirmed that its prior...

The number of studies, the sample size, and the prevalence on HPV infection in general population of each province of China AbstractHuman papillomavirus (HPV) infection which continues to be the most common sexually transmitted disease, has been identified as a major risk factor for cervical cancer. Therefore, it is very important to understand and grasp the distribution of HPV in Chinese population, and make the foundation for the development of cervical cancer vaccine in China. An extensive search strategy was conducted in multiple literature databases. All retrieved studies were screened by October 31, 2018. The prevale...

Human papillomavirus, or HPV, is the most common sexually transmitted infection. Most of the time, the body clears it without problems. But when it doesn’t, it can lead to cancer. HPV is the leading cause of cervical cancer, and it can also lead to cancers of the vagina, vulva, penis, anus, and mouth. Every year, there are more than 40,000 cases of cancer caused by HPV. The HPV vaccine can prevent most of them. Research shows the HPV vaccine is effective A study published in the journal Pediatrics underlined just how effective the vaccine is. Researchers studied women ages 13 to 26 between 2006 and 2017, looking...

This study confirms that hrHPV infection was associated with age, marital status, sympt oms of intercourse bleeding, history of sexually transmitted infections, and sex-related behaviors. Above all, this study provides a baseline database prior to obtaining vaccinations for dynamic tracking of the changes in hrHPV prevalence.

Conclusions High levels of high-risk HPV infection and type-specific persistence were documented, heightening the urgency of mass role out of HPV vaccination. The association between HPV persistence and HIV transmission is a novel finding, warranting further study.
