'we might achieve heard immunity with a smaller vaccinated percentage.' It is crossing back and forth between humans and animals such as cats and deer. Therefore, there can never be herd immunity because it mutates and crosses back to humans. The possibility of herd immunity is not fact based. Some would call the continued presumption of a possible herd immunity to be anti-science, as it can not work.
