Risk of infection in group H relative to group L in the total population and in risk groups, elderly and women of childbearing age (WCA). Relative risks shown with no vaccination and vaccination at 80% of critical vaccination threshold (37% for influenza and 67% for rubella). Forest plots show ranges of relative risk for fixed integration of ξ = 0.15 and a range of a ratio of in-contact rate in social groups (χ = 0.65–0.95) and b ratio of susceptibility in social groups (η = 0.65–0.95)
