This issue concludes our series on influenza. The final two articles in the series emphasize the importance of immunization in preventing infection, the complications of infection, and the risk of transmitting infection to others. In particular, this issue focuses on health-care workers [9] and children at high risk of experiencing complications from influenza [10]. Immunization uptake by these two groups has historically been very low, despite overwhelming evidence of its benefits. Through these articles, we hope to improve awareness and encourage greater participation in the BC influenza immunization program overall.

I would like to once more express my appreciation to all the authors who have kindly dedicated their time and expertise to this series.
