The idea all children are vaccinated and not susceptible is ridiculous. The WHO and CDC are watching four sub variants for trends in infection and and adverse outcomes. That is not at all saying this is over.
Vaccines are nothing more than a nice idea at this point now that there are third level virus. Masks are one of the mainstays of preventing the spread. Eliminating a successful shield from infection with continued variants spinning out is somewhat irresponsible.
I would like to see statistics and scientific rational as to those stating end mask mandates.
