Question

Attack rate for influenza by age and treatment group
age	QIV group	Control group
3-4	3.78%	5.69%
5-8	1.70%	0.15%

Suppose that 80% of 3–4-year-old children and 70% of 5–8-year-old children in a village are vaccinated with QIV vaccine. Also assume that children who are not vaccinated have twice the incidence of influenza as the control group in Table.

What % of 3–4-year-old children in the village will get influenza? (Hint: Use the law of total probability. P(B)=P(B|A1) x P(A1) + P(B|A2) x P(A2) )
