The most common reasons for intending to accept vaccination were "wish to be protected" and "following Health Authority's advice" (fig 3) . The most common reason for refusal was "worry about side effects," and other reasons included "query on the efficacy of the vaccine," "not yet the right time to be vaccinated," and "simply did not want the vaccine" (fig 4) . More than half of the respondents thought that nurses should be the first priority group to receive the vaccines, followed by doctors and allied health professions, and then similar ratings for non-clinical and administrative staff. About half of the respondents (52.2% in the first survey and 56.0% in the second) wanted their family members to receive the vaccines as well. All the above responses remained constant in the different WHO alert phase levels.
