A study published in the Journal of Infectious Diseases shows that the HPV vaccine has reduced the infection rate in teenage girls by more than half, despite low vaccine uptake. The study, published in June, is titled “Reduction in Human Papillomavirus (HPV) Prevalence Among Young Women Following HPV Vaccine Introduction in the United States, National Health and Nutrition Examination Surveys, 2003–2010.”
Study authors analyzed HPV prevalence data from the vaccine era (2007 to 2010), and the prevaccine era (2003 to 2006) and determined that among females aged 14 to 19 years, the vaccine-type HPV prevalence (HPV-6, -11, -16, or -18) decreased from 11.5% in 2003 to 2006 to 5.1% in 2007 to 2010, a decline of 56%. Among other age groups, the prevalence did not differ significantly between the two time periods (P > .05). The vaccine effectiveness of at least one dose was 82.

of Medical Journal Editors (ICMJE) recommends the following citation style, which is the now nearly universally
accepted citation style for scientific papers:

About the ICMJE and citation styles
The ICMJE is small group of editors of general medical journals who first met informally in Vancouver, British Columbia, in 1978 to establish guidelines for the format of manuscripts submitted to their journals. The group became known as the Vancouver Group. Its requirements for manuscripts, including formats for bibliographic references developed by the U.S. National Library of Medicine (NLM), were first published in 1979. The Vancouver Group expanded and evolved into the International Committee of Medical Journal Editors (ICMJE), which meets annually. The ICMJE created the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals to help authors and editors create and distribute accurate, clear, easily accessible reports of biomedical studies.
An alternate version of ICMJE style is to additionally list the month an issue number, but since most journals use continuous pagination, the shorter form provides sufficient information to locate the reference. The NLM now lists all authors.
BCMJ standard citation style is a slight modification of the ICMJE/NLM style, as follows:
- Only the first three authors are listed, followed by "et al."
- There is no period after the journal name.
- Page numbers are not abbreviated.
