^†

Severe reaction was defined as reactions that required medical attention and could not be treated at home

Rate is significantly different between survey years with p < 0.01

Estimates of this decision group differ significantly from “non-hesitant acceptors” and “hesitant acceptors” (p ≤ 0.001)

Estimates of this decision group differ significantly from “delayers” (p < 0.01)

Estimates of this decision group differs significantly from “delayers” (p < 0.05)

Estimates of this decision group differ significantly from “non-hesitant acceptors” (p ≤ 0.001)

Estimates of this decision group differ significantly from “hesitant acceptors” (p < 0.01)

Estimates of this decision group differ significantly from “delayers” (p < 0.001)
