I disagree though I haven't seen data supporting this either way. Many unvaccinated people (those who are not too old or infirm to safely receive the vaccines, which is a significant part of those who remain unvaccinated) are simply going about their lives normally -- that's kind of part and parcel of an antivax mindset as far as I have seen in my life. Whereas many people who are taking the vaccines are also still more cautious about masking, social distancing, etc. So my feeling is that if anything people who aren't vaxxed are more out and about living normal lives.
