Age-specific temporal trends in vaccine acceptability by vaccine roll-out: NIDS-CRAM and CVACS surveys^§: (a) Intention to get vaccinated and (b) trusting vaccine’s safety and efficacy. ^§aOR, adjusted (for age, sex, ethnicity, education, and employment status) odds ratios for the outcomes (i.e., vaccine acceptability); , expected degrees of freedoms from the semiparametric regression models; PAR (%), percent vaccine acceptability (i.e., intention to get vaccinated) associated with the vaccine roll-out periods. For example, compared to the “postvaccine” period, those who participated in “prevaccine” period were 3.6 times more likely to indicate that they would get vaccinated when the vaccine developed; in a combined study population 24% of the mask users were exclusively associated with prevaccine period; this proportion increased to 45% during the vaccine roll-out period.
