COVID-19 has left the world less prepared for an influenza pandemic

Nature Prior to 2020, most pandemic preparedness efforts centered on influenza. Some countries, such as Aotearoa (New Zealand)¹, were able to successfully adapt national pandemic influenza plans to the response to COVID-19, and global influenza surveillance systems were harnessed for SARS-CoV-2 (ref. ²). It is now critical that nations and the international community implement lessons learned from COVID-19 back into influenza preparedness³. This task is particularly urgent given both the emergence of a number of influenza spillover threats and exhausted and depleted public health systems globally.
