I doubt it very much because statistics around the world show that mortality rate in children is far lower compared to influenza.

The swine flu season in 2009/10 killed 380 children.
The bad flu year in 2017/18 killed 172 children
Covid has killed less than 30 and has a long way to go before it catches up with influenza.
