Weekly incidence of influenza-like illnesses (ILIs) in France (French General Practitioner Sentinel network [<b>22</b>]) and weekly pandemic vaccinations in CoPanFlu subjects, weeks 2009–26 to 2010–08.

<p>Blue bars (left scale): national weekly incidence of ILIs; red bars (right scale): number of weekly pandemic vaccinations in CoPanFlu subjects.</p

Geometric mean titer (GMT) in relation to age and pandemic vaccination in the general population.

<p>Red curve: pandemic vaccine recipients (N = 157); green curve: subjects with no pandemic vaccine and no history of influenza-like illness (ILI) (N = 1,067); blue curve: subjects with no pandemic vaccine and history of ILI (N = 95); gray curve: all subjects (N = 1,377). Smoothed GMTs are estimated for subjects aged between 5 years below and 5 years above the indicated age. GMTs are estimated for each interval based on all subjects in the interval and post-stratified with respect to the general population structure.</p

Multivariable models for geometric mean titer ratio in CoPanFlu-France subjects at inclusion.

<p>(B): binary covariates; (Q): quantitative covariates; (L): log-transformed quantitative covariates; GMTR: geometric mean titer ratio; CI: confidence interval.</p

Mean duration of daily meetings (in minutes) of CoPanFlu subjects according to location, age of subjects (±6 months) and age of contacts (±6 months), with 3-year smoothing for both axes.
