A few things that the paper did not mention explicitly, but I think was worth mentioning: - It was AstraZeneca vaccine for both dose. With 4-5 weeks between doses (as opposed to the recommended 8-12 weeks). We have known now that too early 2nd doses will not be as effective. - Healthcare workers includes non direct healthcare staffs of the hospital. The majority of the 69 cases was the IT department of the hospital, iirc. Someone was wondering if the healthcares workers might forgot to wear masks or not. Seeing that they are office workers instead of nurses and doctors, it's possible that they didn't. I don't know if they did or not.
