Australia introduced a human papillomavirus (HPV) vaccination programme with the quadrivalent HPV vaccine for all women aged 12–26 years between 2007 and 2009. We analysed trends in cervical abnormalities in women in Victoria, Australia, before and after introduction of the vaccination programme. With data from the Victorian Cervical Cytology Registry between 2003 and 2009, we compared the incidence of histopathologically defined high-grade cervical abnormalities (HGAs, lesions coded as cervical intraepithelial neoplasia of grade 2 or worse or adenocarcinoma in situ; primary outcome) and low-grade cytological abnormalities (LGAs) in five age groups before (Jan 1, 2003, to March 31, 2007) and after (April 1, 2007, to Dec 31, 2009) the vaccination programme began. Binary comparisons between the two periods were done with Fisher's exact test. Poisson piecewise regression analysis was used to compare incident rate trends. After the introduction of the vaccination programme, we recorded a decrease in the incidence of HGAs by 0·38% (95% CI 0·61–0·16) in girls younger than 18 years. This decrease was progressive and significantly different to the linear trend in incidence before introduction of the vaccination (incident rate ratio 1·14, 1·00–1·30, p=0·05). No similar temporal decline was recorded for LGAs or in older age groups. This is the first report of a decrease in incidence of HGAs within 3 years after the implementation of a population-wide HPV vaccination programme. Linkage between vaccination and screening registers is needed to confirm that this ecological observation is attributable to vaccination and to monitor participation in screening among vaccinated women.

Genomics Explorers, an IBI prize–winning module, engages students with bioinformatics and molecular research. Genomic data sets offer opportunities for students to generate original findings without expensive laboratory equipment, extending the benefits of undergraduate research to the classroom ( 1 – 4 ). Yet, working with data sets online can frustrate biology students who may miss connections to fascinating biological questions. Integrating organismal and molecular biology with bioinformatics can enhance student learning. We have developed a program in genomics, adapted for a plant ( Chamaecrista fasciculata ) and an animal ( Aiptasia pallida ), designed to support student learning with a Web-based guide ( http://serc.carleton.edu/exploring_genomics/index.html ) (see the first chart).
