Impact of HPV Vaccine On The Prevalence Of HPV In Norway

2016-10-18 02:08:21 | BioPortfolio


The overall aim of the study is to assess the effect of school-based Human Papillomavirus (HPV) vaccination by comparing type-specific HPV prevalence between vaccinated and non-vaccinated women born in 1997. Women born in 1997, residence to Norway in 2009 (the year of vaccine initiation of the 1997-cohort) are invited to participate in the study.


This cohort is amongst the first that was offered HPV vaccine in an organized vaccination programme globally. The women will be recruited through Facebook ads. The study will enable us to measure differences in the prevalence of HPV types in vagina and the mouth between vaccinated and non-vaccinated young women in Norway.

The womens vaccination status will be validated by linkage to the Norwegian Immunisation Registry (SYSVAK) and their residence status will be validated through linkage to the Norwegian Population Registry.

Medical and Biotech [MESH] Definitions

The analysis of a chemical substance by inserting a sample into a carrier stream of reagent using a sample injection valve that propels the sample downstream where mixing occurs in a coiled tube, then passes into a flow-through detector and a recorder or other data handling device.

A type of scanning probe microscopy in which a very sharp conducting needle is swept just a few angstroms above the surface of a sample. The tiny tunneling current that flows between the sample and the needle tip is measured, and from this are produced three-dimensional topographs. Due to the poor electron conductivity of most biological samples, thin metal coatings are deposited on the sample.

A solventless sample preparation method, invented in 1989, that uses a fused silica fiber which is coated with a stationary phase. It is used for sample cleanup before using other analytical methods.

The number of units (persons, animals, patients, specified circumstances, etc.) in a population to be studied. The sample size should be big enough to have a high likelihood of detecting a true difference between two groups. (From Wassertheil-Smoller, Biostatistics and Epidemiology, 1990, p95)

Differential thermal analysis in which the sample compartment of the apparatus is a differential calorimeter, allowing an exact measure of the heat of transition independent of the specific heat, thermal conductivity, and other variables of the sample.
