Should have noted in my original post, but I am not as worried about breakthrough infection as I am more concerned about the aspect of it mutating into something that can evade the vaccines. With so many people mingling with each other, with no restrictions,and with no indication of who is vaccinated and who is not, it seems like a recipe for disaster. When the UK and SA variant were making the rounds, we had many restrictions still in place, they caused many infections, but there was still a very proactive effort to end the pandemic. Now with Delta, it has the freedom to spread.
