American boys aren’t getting cancer preventing HPV vaccine

The cancer preventing HPV vaccine, known as Gardasil, Silgard, or Cervarix, is one of the very few ways available to actually reduce the risk of certain cancers. The vaccine reliably blocks HPV infections, which are directly linked to several dangerous cancers such as cervical cancer.

Unfortunately, most boys in the United States aren’t receiving the cancer-preventing HPV vaccine according to a new survey of teen vaccination from the CDC.  This low HPV vaccine uptake may result from the failure of physicians to recommend the vaccine or adequately explain its benefits to parents.

New Gardasil prevents cancer – blocks HPV infection

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.

The new, more powerful, version of the HPV vaccine , recently cleared by the US Food and Drug Administration, protects teens and young adults from 9 subtypes of HPV, helping prevent more cancers. The new vaccine, called Gardasil-9, prevents even more types of cancer.

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).

CDC recommends new Gardasil cancer prevention vaccine

gardasil cancer prevention

As I wrote a few weeks ago, there are limited ways to prevent cancers. There are no magical panaceas that prevent any of the 250 or so cancers. There are no magical supplements or pills. Smoking weed is not going to help. But the new Gardasil cancer prevention is one of the ways.

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.

OK, why aren’t kids getting vaccinated with Gardasil?

Cervical-cancer-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.

Despite the overwhelming evidence that the HPV quadrivalent vaccine, also known as Gardasil (or Silgard in Europe) can prevent human papillomavirus (HPV) infection, the most common sexually transmitted infection (STI) in the USA, which is linked to cervical, anal, vulvar, vaginal, oropharyngeal and penile cancer, HPV vaccine uptake is not as high as other vaccines. A recent report from the CDC, published in Morbidity and Mortality Weekly Report, states that only 57% of girls and 35% of boys, aged 13-17 years, have received at least one of the three recommended doses of the HPV vaccine. This is far short of the goal of Healthy People 2020, the CDC’s initiative to set clear objectives and strategies to improve the health of Americans, that 80% of American teens have received all three doses of the HPV vaccine by 2020.

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.

Gardasil’s safety and effectiveness-Part 47. Long-Term Study

hpv-factsThis 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.

I tend to focus on Gardasil because there is a general understanding that the uptake of Gardasil amongst the target group (young boys and girls) is falling far short of goals. A recent report from the CDC showed that only 57% of girls and 35% of boys, aged 13-17 years, have received at least one of the three recommended doses of the HPV vaccine. Let’s look at it another way–43% of girls and 65% of boys are being put at risk to contracting some very nasty cancers. According to the CDC, roughly 79 million Americans are infected with HPV–approximately 14 million Americans contract HPV every year. Many individuals don’t even know they have the infection until the onset of cancer. Continue reading “Gardasil’s safety and effectiveness-Part 47. Long-Term Study”

Rising rates of HPV-related cancer–Gardasil time for boys and girls

hpv-cell-changes-cancerCurrently 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.

As I reported recently, the HPV vaccine uptake has not been as a high as many would like in the US.  A recent retrospective epidemiological study of HPV cancers in Alberta, Canada, published in the Canadian Medical Association Journal OPEN, seemed to indicate that HPV related cancers have increased substantially in the study years from 1975 to 2009, prior to the widespread use of the HPV vaccine in Canada. This is another indicator that increasing the rate of HPV vaccination is important. Continue reading “Rising rates of HPV-related cancer–Gardasil time for boys and girls”

One-dose HPV-vaccination still works to prevent cancer

The HPV vaccine prevents infection by human papillomavirus, a sexually transmitted disease, specifically subtypes 16 and 18, that not only cause approximately 70% of cervical cancers, but also 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. There is strong clinical evidence that the incidence of HPV infections have declined since the launch of the HPV vaccine and the subsequent steady rate of HPV vaccination.

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.

hpv-vaccine-controversy

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.

We know that the HPV vaccine is safe. Really safe in huge epidemiological studies. And we now have more evidence that it works, and it works better in protecting against HPV infections than so-called “natural immunity.” Unless you believe in lies from the antivaccinationists, HPV vaccines are one of the best ways to protect yourself from cancers.

The importance of the HPV vaccine to gay men

cover-your-buttMany 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. 

These HPV-related cancers can be prevented as long as you can prevent the HPV infection itself, either through never having genital contact with an infected person (and since about 79 million adult Americans are infected with the virus, that’s going to be difficult) or the HPV vaccine. The vaccine is a vitally important part of the war against HPV, it prevents the transmission of certain types (pdf) of human papillomavirus (HPV), specifically types 6, 11, 16 and 18. These subtypes of HPV are most often implicated in these cancers. Continue reading “The importance of the HPV vaccine to gay men”

Study shows HPV vaccine lowers HPV infection risk in teen girls

conservative-HPV-vaccineHPV 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.
