Mr. Chair, we have metrics that we use regularly in terms of how we provide advice.
The guidance advice is based on scientific evidence that is available on the effectiveness, availability and uptake of vaccines, what is evolving domestically and internationally, the epidemiological situation and the effectiveness of other public health measures at keeping people safe. These are a few of the metrics that are actually looked into in terms of making sure we have taken every reasonable precaution to protect health and safety.
