You are a special kind of dumb. Here is the actual report with RNA sequencing test that prove the teacher was the original biological vector. The lack of scientific understanding on this board is appalling. It’s little wonder the rest of the world views Americans as the lowest IQ bunch of the Western world. Read the actual report use your college level reading comprehension skills and see that this irresponsible teacher super spreaders it to the children who had ZERO natural immunity as no human on earth before exposure to a novel virus has natural immunity. Most will recover and carry naturally acquired immunity at that point but they will be infectious for at least ten days once they start to produce active virus. Science is science dumbsh1t politics has no place in it. Delta is highly contagious no legitimate scientist will argue against that.
Leaving the teacher aside, assuming that all the kids were masked, and since this is California I think they probably were, why did the masks not protect the students?
If kids had “ zero natural immunity” they’d have gotten seriously sick or worse. As it was their natural immune systems reduced this virus to a mild equivalent of a cold. That is the best outcome to defeating a novel virus.
Now they won’t catch this particular coronavirus again, or it will be mild if they do.
Some of the infected adults cited in the study were vaxxed.
But those kids will still need to be vaccinated. Right?
...as no human on earth before exposure to a novel virus has natural immunity.
Did you forget that parents' genes are replicated in their children, including t-cell immunity 'memory'? Your ASSumption that none of the parents had immunity from SARS-1, which is 79% similar to CoVID-2, and is showing immunity against the 'delta variant' to be better than the 'jabbed'?
How manny 'vaccinated' teacher / spreaders are walking around that school spewing CoVID-delta?
