Est. weighted US population estimate, CI confidence interval
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)
