Measures to combat Covid during the first three years of the pandemic (such as face masks, social distancing and lockdown) succeeded in decreasing circulation of all respiratory viruses, including flu. 

Less flu circulation during that period has potentially also reduced the amount of general immunity to flu across the population, so there is always the worry that large outbreaks could be more likely. There will also be a cohort of young children and babies, never exposed to flu, that could also be more susceptible. 

Everyone should be as well-prepared as possible, and flu vaccination is the most important precaution.
