> How come they never did this with the flu btw? To mandate that everyone gets the vaccine?
a good comparison. Several reasons:
1) Flu natural R0 is 1.3, COVID 2+ for the Wuhan original, and 4+ for Delta.
2) Flu a- and pre-symptomatic transmission is not significant (see meta-study below). Thus, if you and your kids just stay home or SD or masked when sick, you won’t transmit
3) Most population has flu antibodies and, thus, only very young and very old/weak are vulnerable
4) Flu vaccines are less effective than COVID
If you multiple these factors together, the difference is huge
