However, we were struck by how low the rates achieved in this study actually were. Even in the opt-out group, the vaccination rate of 45% barely exceeded the national average for health care workers (44%),2 far too low. One of the key study findings was that of the 221 participants in the opt-out group who retained an appointment and were sent a reminder email, only 106 of them (48%) eventually were vaccinated. Thus, while an opt-out approach may be useful, it does not appear to be the answer to achieving high rates.
