Correct. Note that there were multiple waves of the Spanish Flu. First wave was fairly mild and hit the young and elderly. Second wave hit the middle aged and wiped out a chunk of the population. The third wave was slightly worse than the first but much less deadly than the second - I couldn't find much detail about it when I last tried. Several theories on why it turned out this way, none of them relevant to the current situation though.
