Currently, 67% of adult Americans have gotten either the first shot of the Moderna or Pfizer vaccine, or the one-shot Johnson & Johnson vaccine. … But drilling down from national rates, the picture varies widely at the regional level, and from state to state. For example, Massachusetts and most states in the Northeast reached or exceeded 70% (for adults 18 and older) in June. Tennessee and most southern states have vaccination rates between 50% and 60%, and administration rates are slowing down.
