I do read carefully. The truth is in the middle. Vaccines don't prevent spread, as out establishment kept insisting to get everyone vaccinated. They do decrease spread.

Managed rationally, this means:

1) Vaccines aren't a reason to reduce other precautions, if you're worried about spread.

2) They are an important part of the solution. Being outdoors doesn't stop spread. High-filtration masks, used by untrained people, don't stop spread. Vaccines don't stop spread. Combine them? R0<<1, and we're all okay.
