Almost 100% of cervical cancers are caused by long-term (over a decade), persistent HPV
Our study found no adverse effects of HPV
vaccination on fertility and indicated that it may, in fact, protect fertility among individuals who have had other STIs," says BUSPH doctoral student Kathryn Mclnerney, the study's lead author.
Boys aren't included in the NHS HPV
vaccination programme as they can't get cervical cancer.
The benefit of the HPV
vaccine is unique to other vaccines in that it is a measure of effective cancer prevention.
8%) offered HPV
genotyping testing, which is significantly higher than 40.
Access to HPV
vaccines for adolescent girls in the Philippines is specially important since cervical cancer remains the second leading cause of death among Filipino women, next only to breast cancer.
infections are the most common sexually-transmitted infections in the United States, and HPV
genotypes 16 and 18 cause approximately 70 percent of cervical cancers worldwide.
The researchers defined high-risk HPV
incidence * (the new-infection rate) as a positive test for a specific HPV
type after two consecutive negative results for that HPV
type at previous study visits.
These benign HPV
types utilise methods to positively avoid infection of deeper tissue (unlike the high risk alpha-PV types mentioned earlier, which infect genital mucosa) as this would induce an immune response to eradicate the virus.
Female study staff used standardized questionnaires in interviews to collect demographic data, information regarding behavioral risk factors, and medical history data relevant to HPV
and related diseases.
types 16 and 18 cause about 70% of cervical cancers.
Results showed that 94% of women tested positive for at least one high-risk type of HPV
(type 16, 18, 31, 33, 35, 39, 45, 52 or 58) at some time during follow-up, and 42% specifically tested positive for HPV
