Reaching the elusive herd immunity in Pima County has proven difficult as vaccine administration steadily decreased beginning in April. While some people remain hesitant to get a shot or simply are refusing to do so, health officials attribute the struggle to vaccinate to a lack of access. According to Dr. Jeff Burgess, principal investigator of AZ HEROES study, they found that two doses of the mRNA vaccines, either Pfizer or Moderna, were 91% effective in preventing COVID-19. For breakthrough cases, the infection was much shorter, much less severe than if you hadn’t been vaccinated and furthermore, there was less virus there and for a shorter period of time than if you had not been vaccinated.
