HPV Vaccine Reduces Infection Rates in Teen Girls

Since the human papillomavirus (HPV) vaccine was introduced in 2006, vaccine-type HPV prevalence has decreased by 56 percent among females 14-19 years old, according to a new study published in The Journal of Infectious Diseases.

HPV is the most common sexually transmitted virus in the United States. Although the vast majority of HPV infections do not cause serious harm, some will persist and can lead to cervical cancer. Each year in the U.S., about 19,000 cancers caused by HPV occur in women.

“Unfortunately, only one-third of girls aged 13-17 have been fully vaccinated with HPV vaccine,” says CDC Director Tom Frieden, M.D., M.P.H. “Our low vaccination rates represent 50,000 preventable tragedies, which means 50,000 girls alive today will develop cervical cancer over their lifetime. This would be prevented if we reach 80 percent vaccination rates. For every year we delay in doing so, another 4,400 girls will develop cervical cancer in their lifetimes.”

Study author Markowitz notes that the decline in vaccine type prevalence could be due to factors such as “Herd” Immunity (also called “community immunity”), which occurs when most members of a community are protected against a contagious disease because a critical portion of the population has been immunized and the opportunities for an outbreak are reduced. “Herd” Immunity has been shown to control a variety of contagious diseases, including measles, mumps, rotavirus (MMR), influenza and pneumococcal disease.

Public health experts recommend routine HPV vaccination at ages 11-12 for both boys and girls. A series of three shots is recommended over six months. HPV vaccination is also recommended for older teens and young adults who were not vaccinated when younger.

The HPV vaccine is not without its critics, and health care providers are not consistently giving strong recommendations for the vaccine, particularly for younger teens, according to the CDC.

“One of the most common criticisms from parents – that their teen is not sexually active yet – misses the point,” suggests Frieden, who says that vaccines should be administered well before people are exposed to an infection.

Frieden also points out that, with the Vaccines for Children Program and the Affordable Care Act, vaccination is easy and cost should not be a barrier because many insurers are required to cover the vaccine at no cost to either female or male patients.

The power of an effective and widespread vaccination program should not be ignored. Smallpox, for example – a serious and sometimes fatal infectious disease – has no specific treatment and is only prevented by a vaccine. Although outbreaks of the disease have occurred from time to time over thousands of years, it is now eradicated worldwide because of a successful and comprehensive vaccination campaign.

A similar initiative is underway to eradicate polio worldwide. The development of effective vaccines to prevent paralytic polio was one of the major medical breakthroughs of the 20th century. Supported by the Bill & Melinda Gates Foundation, the Global Polio Eradication Initiative (GPEI) has helped to reduce the incidence of polio by more than 99 percent.

As with smallpox, if enough people in a community are immunized, the virus will be deprived of susceptible hosts and will die out. But high levels of vaccination coverage must be maintained to stop transmission and prevent outbreaks.

Will HPV go the way of smallpox and polio thanks to “Herd” Immunity? Do you agree with the CDC that it’s time to ramp up efforts to protect the next generation with the HPV vaccine? Or do you share the critics’ concerns?

Real-Time Health Alerts Join Twitter to Expand Access to Public Health Information

Is Twitter now monitoring your allergies or sleeping patterns?

In today’s era of real-time information, Twitter has emerged as a leading go-to source for the latest in news, entertainment and more. Now, Twitter is joining Everyday Health, Inc. to create HealthBeat, the first global real-time health alert and news offering. The partnership seeks to provide relevant health information and breaking news to the Twitter community in real time, offering promoted Tweets linking to Everyday Health’s news, expert advice, videos and tools that users can put into action.

HealthBeat will scour the 2 million daily health-related tweets in the U.S. to identify impending outbreaks and other health crises.

“We’ll be looking at the key health terms flaring up every day, and when something is indexing in an abnormal way, we’ll let Twitter know and we’ll supply content about what to do,” said Everyday Health President Michael Keriakos, in an interview published in Ad Age.

For example, Keriakos noted that HealthBeat could have been used to provide vaccination information to residents affected by a whooping cough outbreak in South Central Los Angeles two years ago.

Not only will the partnership provide important information relating to public health, it will also serve as a targeting mechanism for advertisers who are being sought by HealthBeat to promote content around broad health topics like allergies, flu season and insomnia.

While HealthBeat touts itself as the “first global real-time health alert” service, there are other online services – like Google’s flu tracker — that provide similar information on a regional or national level:

  • Launched in 2010, Health & Safety Watch is a Canadian-based web portal and iPhone app that lets users customize the type of alerts they want to see. It also indicates when an advisory or warning is over, for example, when a local water quality issue has been resolved.
  • In the U.S., the Centers for Disease Control and Prevention (CDC) provides alerts about health issues travelers may face when going abroad as well as alerts about disease outbreaks at home.
  • Also in the U.S., a service called HealthMap, developed out of Boston Children’s Hospital, offers an online portal called The Disease Daily, and a mobile app called Outbreaks Near Me.

“The sooner we get a signal of an infectious disease outbreak, the sooner we can devise an appropriate response, and hopefully, the negative impacts can be mitigated,” explained Anna Tomasulo, MA, MPH, HealthMap Program Coordinator, Boston Children’s Hospital.

According to Tomasulo, HealthMap has other tools that help prevent health problems.

“Our Vaccine Finder takes a person’s zip code and provides information on where they can access vaccines nearby,” she says, noting that the project started with flu vaccines but has since been expanded to other vaccines including human papillomavirus (HPV), measles, mumps and rubella (MMR), Varicella and more. “A questionnaire helps users determine what vaccine is most appropriate and provides a list of participating pharmacies within a given radius that provides the vaccine the user needs. Such vaccines help prevent costs associated with illness and potential hospital stays.”

So are HealthBeat, HealthMap and other real-time alert programs providing an important public health service? Are these alerts helpful or will they cause undue concern?
