“As Covid-19 vaccine rollout continues to break records in Kentucky, there is a concern that interest could peak and the vaccinations could plateau before we reach herd immunity,” which is needed to protect people who can’t or won’t get vaccinated, reports Chad Hedrick of Lexington’s WKYT-TV.
“Dr. Ryan Stanton says the latest survey shows around 50 to 55 percent of Kentuckians will get the vaccine when they can,” Hedrick reports. “To reach herd immunity, the magic number is 75 to 80 percent. Stanton says we won’t know for sure how short or close we are to those levels until mid-year.”
Stanton, an emergency-room physician, and other doctors worry that the lack of herd immunity would lead to “flare-ups of cases year-round and chances for the virus to mutate easier,” perhaps into more contagious strains, Hedrick reports.
