Quantifying the impact of social groups and vaccination on inequalities in infectious diseases using a mathematical model

Table 2 Percentage increase in risk of infection in group H relative to group L due to vaccination

Driver of inequality	Infection	Population group	Increase in relative risk
Difference in contact rate	Influenza	All	4–162%
	Influenza	Elderly	3–137%
	Rubella	All	2–39%
	Rubella	WCA	4–72%
Difference in susceptibility	Influenza	All	5–241%
	Influenza	Elderly	5–203%
	Rubella	All	2–49%
	Rubella	WCA	5–86%

Percentage increases in relative risk of infection for the total population (all), women of childbearing age (WCA) and elderly. Results calculated when either the relative within-group contact rate of the two social groups is varied (‘contact’ parameter) or when the relative susceptibility of group L to group H is varied (‘susceptibility’ parameter) (Table 1). Integration between the social groups is set at its base case value
