"Being vaccinated isn't a perfect defense, but it reduces the risk to you of getting the disease, it drastically reduces the risk to you of dying from the disease or suffering long term life altering consequences from it, and it lowers the risk of you spreading it to others."

The general guidance hasn't changed. The risk to each other has gone up as Delta spreads, because it's more dangerous. There will probably be other dangerous variants given the huge breeding ground for the virus among the unvaccinated and immune compromised.

Get vaccinated, lower your risk, lower the risk to everyone around you and to the general population of the earth. (And it's incredibly harmless).
