 13-17才の女子の4人に1人がHPVワクチン接種を受けたと連邦CDC疾病管理・予防センターが発表した。メルク社のHPVワクチンGardasilは3回の接種で子宮頚癌の70%が予防可能とされ強く推奨され、11-12才の接種が勧められている。
 ワクチンの提案者は、毎年米国でなくなる約4,000の子宮頸癌死者を減らすことができるとして、ずっと高い予防接種レートを望んでいた。しかし多くの家族は安全性に対して用心深いという。多くの健康保険業者がカバーするが、約375ドルと高価であるし、生涯にわたり免疫を得られるかどうかわからず、追加免疫が必要かもしれない。
 ワクチンは2006年に発売され、CDCは2007年暮れに調査を行った。

1 in 4 US Teen Girls Got Cervical Cancer Shot
Cervical Cancer Vaccination Rate at 25 Percent for Teen Girls One Year after Shot's Approval

About one in four teen girls last year got the groundbreaking vaccine that prevents cervical cancer, federal health officials reported Thursday.

The figures represent the government's first full year of vaccination rate data for the Gardasil vaccine, which came on the market in mid-2006. Merck & Co.'s heavily advertised, three-shot series targets the sexually transmitted human papillomavirus.
Health officials recommend that girls get the shots when they are 11 or 12, if possible, before they become sexually active. Also, age 11 is when kids are generally due for another round of vaccinations.
The survey only covered children in the 13-17 age range.
Vaccine proponents had been hoping for much higher vaccination rates, saying the shots could dramatically reduce the nearly 4,000 cervical cancer deaths that occur each year in the United States.
But many families are cautious about the safety of new vaccines, said Patti Gravitt, a Johns Hopkins University associate professor of epidemiology.
Other things about the vaccine may give some families pause. It is expensive, retailing for about $375, although many health insurers now cover it. And there are questions about whether it confers lifetime immunity or if a booster shot will be needed.
"Some parents may be adopting the attitude with their daughters that, 'Well, you're still young. I can wait a couple more years before you're sexually active,'" said Gravitt, who was not involved in the research.
"My personal opinion is that this seems quite reasonable after the first year," Gravitt said, of the 25 percent vaccination rate.
Merck officials said they were pleased with the vaccination rate.
The Centers for Disease Control and Prevention based the study on household telephone surveys done in late 2007. The results are based on nearly 3,000 teens ages 13 to 17 for whom the researchers could verify vaccination information through medical records.
Of the girls in the survey, 25 percent had gotten at least one Gardasil shot.
The CDC, which has been promoting other shots for adolescents, also studied other teen vaccination rates.
About 32 percent of teenagers got a recommended meningitis shot last year, up from 12 percent in a 2006 survey. Also, 30 percent got another relatively new shot, one that guards against tetanus, diphtheria and whooping cough. That's up from 11 percent the year before.
As with the cervical cancer shot, health officials say children should get both those shots when they are 11 or 12.
About 75 to 90 percent of children got the better-known vaccinations that have long been required by schools, such as chickenpox, hepatitis B and measles, mumps and rubella, the study found.
"The overall trends are good news," said Dr. Lance Rodewald, director of the CDC's Division of Immunization Services, in a prepared statement.
"We are seeing more preteens and teenagers being protected against serious, sometimes deadly diseases. But we remain short of our goals. For almost all of these vaccines we want at least 90 percent of adolescents to be fully immunized."

Cancer Vaccine Used by 25% of Girls 13 to 17

By THE ASSOCIATED PRESS
Published: October 9, 2008
ATLANTA (AP) ― One in four teenage girls have received the relatively new vaccine against cervical cancer, federal health officials said Thursday.
The figures represent the government’s first substantial study of vaccination rates for the vaccine, Gardasil, which is Merck & Company’s heavily advertised three-shot series that goes after the sexually transmitted human papillomavirus, or HPV. The vaccine protects against strains of the virus that cause about 70 percent of cervical cancers.
Health officials recommend that girls get the shots when they are 11 or 12, if possible, before they become sexually active. Also, 11 is the age when children are generally due for a round of vaccinations.
The survey covered children only from 13 to 17.
Proponents of the vaccine had been hoping for much higher vaccination rates, saying the shots could significantly reduce the nearly 4,000 cervical cancer deaths that occur each year in the United States.

The Centers for Disease Control and Prevention based the study on household telephone surveys in late 2007. The survey results cover from when the vaccine came on the market, in mid-2006, to when the survey questions were answered.
The results are based on nearly 3,000 girls ages 13 to 17 for whom the researchers could verify vaccination information through medical records.
