KHOU-TV (CBS) Ch. 11 Houston TX (Internet / TV) 05/18/06 A vaccine that blocks infection by the two types of viruses that cause most cases of cervical cancer is safe and effective and should be approved, a federal panel recommended Thursday. A Food and Drug Administration advisory committee voted 13-0 on five separate times to endorse the vaccine, known as Gardasil and made by Merck and Co. The vaccine could reduce by more than two-thirds the number of deaths worldwide from the second-leading cancer in women, according to the company. Giving girls as young as 9 a first-ever vaccine that blocks infection by four types of human papillomavirus could slash global deaths from cervical cancer by more than two-thirds, Merck & Co. officials said.
