Genital human papillomavirus (HPV) is the most common sexually transmitted infection (STI) in the USA. There are more than 40 HPV sub-types that can infect the genital areas of males and females. Additionally, some HPV types can also infect the mouth and throat. HPV is generally transmitted from personal contact during vaginal, anal or oral sex.
This newest version of the HPV cancer-preventing vaccine safely and effectively prevents several forms of cancer in young adults by protecting the those who receive the vaccine from nine different types of the HPV virus. In a clinical study, published in Pediatrics, 3066 girls and boys, aged 9 through 15, were given a three-dose series of the new Gardasil-9 vaccine–day 1, month 1, and month 6.
The researchers observed no serious adverse events and high immunogenicity (antibodies to all 9 HPV types).
There are just a few methods to actually prevent cancers – stop smoking, stay out of the sun, lose weight, avoid radiation, and get the HPV vaccine. Yes, one of the handful of ways to prevent cancer, debilitating and dangerous ones, is to get the HPV vaccine.
This is my 48th article about Gardasil, following by just a few hours, my 47th. After my 50th, I get a watch made from the gold hidden in the subterranean vaults of the Big Pharma overlords who generates bundles of cash from vaccines. Oh, I keep forgetting–that’s not true.
Currently in the United States, the Advisory Committee on Immunization Practices (ACIP) recommends that preteen girls and boys aged 11 or 12 are vaccinated against HPV. The immunization is also recommended for teenage girls and young women up to the age of 26 who did not receive it when they were younger, and teenage boys and young men up to the age of 21.

This is my 47th article on the HPV quadrivalent vaccine, also known as Gardasil (or Silgard in Europe), which can prevent infection by human papillomavirus, substantially reducing the risk of several types of cancers.* Forty-seven** articles about Gardasil and the HPV vaccine! You’d think I would be tiring of it by now, but I think that Gardasil (or Silgard) are critically important in easily stopping cancers.
I find it ironic that people are always looking for the next “cancer cure”, but here’s Gardasil which prevents cancer from even starting. Which people seem to ignore for their children, even if, as parents, they vaccinate their children for everything else.

In a community-based phase III trial of Cervarix (bivalent HPV vaccine) in Costa Rica, researchers reported that the Costa Rica Vaccine Trial (CVT) showed that the four-year vaccine efficacy against 12-month HPV subtypes 16 and 18 (HPV16/18) persistent infections was similarly high among women who received one, two, or the recommended three doses of the bivalent HPV16/18 vaccine. The researchers examined nearly 7,500 women, aged 18-25, in Costa Rica to determine both vaccine uptake (what percentage were vaccinated), number of doses, and HPV16/18 antibodies.
Some of the key results:
About 80% of the participants did get all three recommended doses, leaving about 20% who got one or two doses.
Researchers analyzed blood samples for HPV16/18 antibodies in randomized subsets who received one, two or three doses.
Antibodies to HPV16/18 was observed in 100% of women 48 months after vaccination with one, two or three doses. The only difference noticed that it appeared to take a slightly longer average period of time for 100% of the one-dose group.
Almost all participants in all vaccine dose groups were seropositive at approximately 1 month after receiving the first vaccine dose and remained seropositive throughout the 48 months follow-up period.
The researchers also compared “a natural infection group” against those who were vaccinated with Cervarix. For those vaccine deniers who say “natural infection is better”, the titers of HPV16/18 antibodies were 14-24X higher with two-doses of the vaccine, while the titers were 5-9X higher with one-dose vaccinations.
The authors concluded:
The high efficacy after single dose suggests that long-term protection may not require the 5- fold higher titers induced by three doses of the vaccine. Fewer doses would be less expensive and logistically easier to deliver, therefore increasing vaccine accessibility worldwide. The findings also suggest that second generation vaccines might be strongly protective even if they do not induce the high levels of antibodies induced by the licensed vaccines as used according to current recommendations.
Many of us who provide scientific information about HPV quadrivalent vaccine, also known as Gardasil (or Silgard in Europe), tend to focus on its effects on preventing cancers in women, so articles are inclined to pay attention to vaccinating teenage girls rather than boys. But, if you carefully analyze the disease, human papillomavirus, a sexually transmitted disease, its subtypes 16 and 18 not only cause approximately 70% of cervical cancers, but they cause most HPV-induced anal (95% linked to HPV), vulvar (50% linked), vaginal (65% linked), oropharyngeal (60% linked) and penile (35% linked) cancers. The viruses are generally passed through genital contact, almost always as a result of vaginal, oral and anal sex.
HPV quadrivalent vaccine, also known as Gardasil (or Silgard in Europe), is marketed by Merck, usually for vaccination of teenage girls (with an increasing number of boys). The vaccine prevents the transmission of certain types (pdf) of human papillomavirus (HPV), specifically types 6, 11, 16 and 18. HPV types 16 and 18 cause approximately 70% of cervical cancers, and caused most HPV-induced anal (95% linked to HPV), vulvar (50% linked), vaginal (65% linked), oropharyngeal (60% linked) and penile (35% linked) cancers. These cancers, mostly related to HPV, can be prevented as long as you can prevent the HPV infection from ever happening, which usually happens through genital contact, most often during vaginal and anal sex. HPV may also be passed on during oral sex and genital-to-genital contact. HPV can be passed on between straight and same-sex partners—even when the infected partner has no signs or symptoms. Approximately 79 million Americans, most in their late teens and early 20’s, are infected with HPV, and about 14 million people become infected each year in the USA.
