With all of the talk of herd immunity, I don't think we'll ever get there, based on local vaccination numbers. Although I live in a rural county, I believe we are a microcosm of vast rural areas of the US as a whole. As of yesterday, 31% of our population age 18+ have been fully vaccinated. Our local shot clinic operated by the County health department can vaccinate ~400 individuals a day. This is in addition to three other pharmacies providing vaccinations. The good news is that 79% of those 65 and older have been vaccinated.
However, starting this week, the reservation numbers have dropped dramatically, to the point of shutting down the clinic this Thursday due to lack of reservations (not completely, just for that day.) At this rate, I'm estimating that only a little over 50% of the 18+ age group will be vaccinated by July 1st. Without some emphasis being placed on reducing vaccine hesitancy, this may become the Vietnam of pandemic battles.
