Influenza vaccine effectiveness
Vaccine effectiveness is an estimate of the likelihood that a vaccine prevents influenza infection when used in everyday practice. To establish how well influenza vaccines work each season, influenza vaccine effectiveness is measured in observational studies.

It is crucial to estimate the proportion of the total population of persons living with HIV, including those that are not yet diagnosed, in order to understand the burden of HIV and the need for antiretroviral treatment and other HIV-related care.

It is expected that up to ~15% of a European population in a temperate climate is infected with influenza in any winter season with higher percentages in children and lower in older people.
