Wow, quite a teacher. She gave most of her students natural immunity to COVID-19, the strongest immunity you can now get. /not sarc
The strongest immunity is from natural infection. We used to know this, but now the world is full of people like you, who somehow believe a vaccine is a magic elixir.
The best a vaccine can do is help the immune system learn. Do you believe the immune system learns nothing from the virus itself?
With our new wiz bang “vaccine” the immune system only learns of the spike protein. And people like you thought it would be enough. It of course is not, as it does not stop infection nor transmission.
Add to that, the fact that your beloved elixir applied very narrow pressure to a notorious mutator. And you thought the virus would not find its way around this narrow pressure…..so very foolish.
