> Sweden's official death toll was 2270 yesterday (2020-04-28). The three worst influenza seasons in Sweden since 1969 killed 807, 674 and 652 people[1]. So we've already passed his "at most" claim. The only way I can see that working out is if he feels that none of the influenza seasons in the past 50 years count as "severe".

Sorry, but you can't just throw around numbers without explaining exactly what they mean or where they come from. The numbers you're quoting is most likely deaths that has been diagnozed as influenza. To get the full picture you need to look at excess mortality (which is reported by EuroMOMO[1]) and possibly adjust the numbers to pick out the influenza-related excess (FluMOMO[2] is the model most countries use).

If you look at the 2016/2017 season in Sweden [3, figure 17, page 46] you will see that the excess mortality as reported by FluMOMO goes way beyond ~600 for a season. In the peak season we see that it was ~300 per week. There are of course uncertainties in these numbers (which is why you won't see any official "x number of people died of influenza" figures), but it was probably closer to thousands than hundreds in 2016/2017.
