The National Vaccine Information Center yesterday warned state officials to investigate the safety of a breakthrough cancer vaccine as Texas became the first state to make the vaccine mandatory for school-age girls.
Negative side effects of Gardasil, a new Merck vaccine to prevent the sexually transmitted virus that causes cervical cancer, are being reported in the District of Columbia and 20 states, including Virginia. The reactions range from loss of consciousness to seizures.
"Young girls are experiencing severe headaches, dizziness, temporary loss of vision and some girls have lost consciousness during what appear to be seizures," said Vicky Debold, health policy analyst for the National Vaccine Information Center, a nonprofit watchdog organization that was created in the early 1980s to prevent vaccine injuries.
Following federal approval of the vaccine in July 2006, a storm of legislation was introduced across the nation that would make the vaccine mandatory in schools. The District and Virginia are part of a group of at least 17 states considering such legislation. A measure had been introduced in Maryland, but it was shelved last week over concerns about the mandatory language in the bill.
Yesterday, Texas Gov. Rick Perry signed an order making Texas the first state to require the vaccine. Girls ages 11 and 12 would receive the human papillomavirus (HPV) vaccine before entering the sixth grade starting in September 2008.
The American Cancer Society estimates there were 9,710 new cases of cervical cancer in the United States in 2006. The District's cancer control center estimates a total of cervical cancer cases in the city last year, and the American Cancer Society estimates that last year Maryland and Virginia each had 210 cases of cervical center.
Merck began marketing Gardasil last year after the Food and Drug Administration approved it for females ages 9 to 26. The vaccine is the first of its kind to build immunity against two strains of HPV, which lead to 70 percent of cervical cancer cases in the United States.
The vaccine is not effective in men, who can get cancer from other strains of HPV.
Its side effects were reported to the Vaccine Adverse Event Reporting System, a federal reporting system for consumers to notify federal regulators of bad reactions to medications. The adverse events began being reported in July 2006, when an advisory panel to the Centers for Disease Control and Prevention recommended girls ages 11 and 12 receive the series of shots.
The types of side effects reported are not cause for alarm, according to the American Cancer Society.
