HPV vaccinations lagging despite strong safety and effectiveness

hpvThe CDC recently reported that only about half of US teenager girls have received the safe and effective quadrivalent HPV vaccine (HPV4), a disappointing level of vaccine uptake. Moreover, this rate hasn’t changed over the past three years, despite significant efforts to increase the awareness and effectiveness of the vaccine amongst teenagers. Even worse news in this report is that only about one-third of teenage girls have been fully immunized with all three doses.

HPV quadrivalent vaccine, also known as Gardasil (or Silgard in Europe), is marketed by Merck & Co., 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.

Human papillomavirus (HPV) is a virus from the papillomavirus family that is capable of infecting humans. Like all papillomaviruses, HPVs establish productive infections only in keratinocytes of the skin or mucous membranes, making it easily transmitted sexually or through other intimate contact. While the majority of the known types of HPV cause no symptoms in most people, some types can cause warts (verrucae)HPV types 16 and 18 cause approximately 70% of cervical cancers, and cause most HPV-induced analvulvarvaginal, and penile cancers. The HPV quadrivalent vaccine, also known as Gardasil (or Silgard in Europe), is marketed by Merck. The vaccine prevents the transmission of certain types of HPV, specifically types 6, 11, 16 and 18

Updates: LeRoy mystery neurological illnesses

This article is an update of one I wrote several months ago. I had presumed the story had ended. It hadn’t.

Background

In spring 2012, I had written a few articles about a mystery neurological ailment that had struck about 20 teenagers at a high school and surrounding area in LeRoy, NY, a small town about 30 minutes from the city of Rochester. They suffered tics that mimicked Tourette syndrome, but was never diagnosed as such. Most of them have recovered, although two new cases have appeared.

Medical and scientific findings

First, Erin Brockovich, yes THAT Erin Brockovich, decided to get involved. In an announcement in August, they stated that they found nothing:

There is no link specifically that I can draw to environmental exposure because there are so many environmental exposures that occurred at the high school.  Continue reading “Updates: LeRoy mystery neurological illnesses”

Religion vs Gardasil

gardasil.colorAlthough I rarely state it on these pages, I am an atheist. As a scientist, I’ve examined the evidence for a god (any god), and found it lacking. I think religion, especially in the USA, can be dangerous. Religious fundamentalism is behind the attack on teaching of real science, such as evolution and global warming. Although some may argue that trying to block the teaching of evolution, in favor of creationism, is innocuous (though absolutely unconstitutional), most would argue that since evolution is the basis of all biology (and therefore, medicine), it is harmful. 

It’s when fundamentalist religion gets involved in medicine, whether it’s therapeutic abortions, vaccines, or stem-cell research, that it’s clear that religion becomes dangerous to human lives. I just want to focus on one tiny corner of the medical world, where religious beliefs block good medicine–HPV vaccinations.

For those of you may be unfamiliar with the HPV vaccine, it prevents infection by the human papillomavirus (HPV), a sexually transmitted disease. The vaccine, known as Gardasil or Cervarix in the USA, specifically blocks HPV types 6, 11, 16 and 18; HPV types 16 and 18 cause approximately 70% of cervical cancers, and cause most HPV-induced analvulvarvaginal, and penile cancers. Cervical cancer, which afflicts 12,000 additional women and causes over 4,000 deaths annually in the USA, is considered the “preventable gynecologic cancer” because of the HPV vaccines.

Survey identifies reasons for not vaccinating teens

vacs-save-lives-003Vaccines are one of the most important and crucial aspects for the long-term health of babies and young children. Except for a tiny, and irresponsible, minority of individuals who are opposed to vaccinations, greater than 95% of children are fully vaccinated for most vaccine preventable diseases by kindergarten. Unfortunately, a recently published article in Pediatrics provided evidence that teens are not keeping up with vaccinations that are critical to avoid infections from serious, and deadly, diseases. The study examines how vaccination rates have changed over the three year study period, and some of the reasons why they are not getting vaccinated.

I get an email about Gardasil

hpv posterI get lots of email about my articles that are published here. Sometimes, it’s about grammar or spelling (and the grammar KGB can be uncivil at times). Sometimes, it’s compliments or questions about what I’ve written. Rarely, they’re rude and usually include quite immature comments about the location of my head. However, I recently received an email that is more or less polite, but is filled with so many errors and logical fallacies, that I thought it should be critiqued publicly.

Here are my point-by-point comments about the email:

I stumbled across your blog and could not believe what I was reading about the safety of Gardasil.  As a mother of a Gardasil injured daughter, your profuse endorsement made me skeptical.  I want to begin by saying I am not anti-vaccine;  I am anti-Gardasil.  Continue reading “I get an email about Gardasil”

HPV–early vaccination maximizes effectiveness

 

HPV protesters in Texas.

Human papillomavirus (HPV) is a virus from the papillomavirus family that is capable of infecting humans. Like all papillomaviruses, HPVs establish productive infections only in keratinocytes of the skin or mucous membranes, making it easily transmitted sexually or through other intimate contact. While the majority of the known types of HPV cause no symptoms in most people, some types can cause warts (verrucae). HPV types 16 and 18 cause approximately 70% of cervical cancers, and cause most HPV-induced anal, vulvar, vaginal, and penile cancers. The HPV quadrivalent vaccine, also known as Gardasil (or Silgard in Europe), is marketed by Merck. The vaccine prevents the transmission of certain types of HPV, specifically types 6, 11, 16 and 18

Although the safety of HPV vaccine has been thoroughly vetted for safety in studies with large cohorts, the long time period (up to decades) from infection to a diagnosis of an HPV-related cancer has left questions about how to maximize effectiveness of the vaccine which required further research.  Continue reading “HPV–early vaccination maximizes effectiveness”

Why do Americans hate Gardasil?

In next week’s issue of Forbes, Matthew Herper, the magazine’s medical editor, penned the article, The Gardasil Problem: How The U.S. Lost Faith In A Promising Vaccine, an insightful analysis of why Gardasil, the vaccine for human papillomavirus (HPV), has not become as important to vaccination strategies as measles or whooping cough.  All vaccines keep you alive, even if the disease does not appear to be scary.  There’s a belief, especially amongst the anti-vaccination crowd, that measles is just a few spots, and there are few risks to being infected.  The risk of severe complications is small, but significant.

On the other hand, the HPV vaccine does one thing and does it well–it prevents an HPV infection.  Human papillomavirus, a sexually transmitted disease, causes 70% of cervical cancers, 80% of anal cancers, 60% of vaginal cancers, and 40% of vulvar cancers.  It also prevents the majority of HPV caused oral cancers.  In other words, these diseases are in a different league of danger.  And they can be prevented.

CDC makes recommendations on the use of HPV vaccine in males

The CDC’s Advisory Committee on Immunization Practices (ACIP) recommends routine vaccination of males aged 11 or 12 years with HPV4 administered as a 3-dose series (recommendation category: A, evidence type: 2§). The vaccination series can be started beginning at age 9 years. Vaccination with HPV4 is recommended for males aged 13 through 21 years who have not been vaccinated previously or who have not completed the 3-dose series. Males aged 22 through 26 years may be vaccinated. Continue reading “CDC makes recommendations on the use of HPV vaccine in males”
