Vaccine controversy continues

Source: Reader's Digest (www.rd.com) Author: Julie Bain Between the relay races and table tennis triumphs last week, there was some news coverage about the HPV vaccine. A study came out last Wednesday in the New England Journal of Medicine that looked at the economic impact of vaccinating young girls and women from the types of HPV virus that can cause cervical cancer. Newsweek ran an informative Q and A with one of the study authors about who should get the vaccine and when. The New York Times did a big story, too, which I thought displayed a bit of bias in the disapproving tone of its headline: Researchers Question Wide Use of HPV Vaccines. I called Maura Gillison, MD, a researcher at Johns Hopkins in Baltimore and one of the top experts on HPV, for her perspective. She said, “For those of us in the field, this study is not really new information. It is known that the HPV vaccine doesn’t have an impact on young women who have already been infected by the HPV types targeted by the vaccine (HPV6, 11, 16, and 18).” While it was possible to measure a girl’s previous exposure to HPV in the study lab, it’s not possible in a medical clinic, she says. That’s why it’s not as cost-effective to give the vaccine to women who are already sexually active. Still, she says, “only 4% of the 16- to 26-year-old women who were enrolled in the vaccine trials had evidence of exposure to [...]

Gardasil vaccine eradicating human papillomavirus infections

Source: news.com.au Author: Kate Sikora The new cervical cancer vaccine is expected to almost eradicate human papillomavirus (HPV) infections in Australian women by 2050 if the high rate of immunization amongst girls continues. Research to be released today by the Cancer Council NSW reveals the number of new HPV cases in women will fall by more than 50 per cent in the next two years. In 40 years, the number of cases will fall by 97 per cent. A national program launched last April has seen 3.7 million girls vaccinated with Gardasil, which has the potential to prevent up to 70 per cent of cervical cancers. Before the vaccination program, there were 108,000 new infections of HPV16 - responsible for 50 per cent of cervical cancers - every year, but that number is expected to fall to 47,000 by 2010. Dr Karen Canfell, lead author of the study, warned the reduction in HPV would only occur if girls continued to be vaccinated. "We expect to see a very fast reduction in the number of new HPV infections, largely due to the high school vaccination program, which we estimate has achieved high coverage of just over 80 per cent of 12-13-year-old girls," she said. "This reduction will only occur if we maintain this high vaccination coverage among younger age groups." Gardasil has attracted controversy over its rate of adverse reactions. Nationally, there have been 1013 reports of adverse side effects from Gardasil to the Therapeutic Goods Administration. Girls have reported allergic [...]
