Tell you this much for certain .... if you are vaccinated you are FAR less likely to become infected even with the Delta variant.
Logically it follows that if you are far less likely to become infected in the first place then you are also far less likely to infect anyone else.
Therefore the more people get vaccinated, the safer EVERYONE will be.
Irrefutable logic. The unvaccinated are the unraked forest that's breeding wildfires that could burn down your house (to make a trope of Trump's absurd statement). Wise up, people. The willfully unvaxxed are fucking things up for everybody. Unless there are valid reasons for their not getting vaxxed they are either stupid or in denial, or both, of course. Then there's just plain laziness. Moral bankruptcy is an even worse disease than Covid-19, but rather a different sort of thing. There's no pathogen, but it does grow in the human brain:
The Human Abstract, by William Blake
Pity would be no more,
If we did not make somebody Poor:
And Mercy no more could be,
If all were as happy as we;
And mutual fear brings peace;
Till the selfish loves increase.
Then Cruelty knits a snare,
And spreads his baits with care.
He sits down with holy fears,
And waters the ground with tears:
Then Humility takes its root
Underneath his foot.
Soon spreads the dismal shade
Of Mystery over his head;
And the Caterpillar and Fly,
Feed on the Mystery.
And it bears the fruit of Deceit,
Ruddy and sweet to eat;
And the Raven his nest has made
In its thickest shade.
The Gods of the earth and sea,
Sought thro' Nature to find this Tree
But their search was all in vain:
There grows one in the Human Brain.
