They were fear-mongering last year about the possibility of flu and covid co-infection. So they were pressuring people to take the flu vaccine. In fact my family pressured me to take the flu vaccine in 2020 and I did. Because I figured that at least the flu vaccine has decades of trials, research and development behind it. Unlike the covid vaccine. So I think it's entirely possible that covid may have emerged as the dominant virus and muscled out the flu. If flu and covid co-infection was a thing, they would have ran with it. Because they were fearmongering about the possibility of it last year.
