The answer to possibly the most asked question during the last year “How much longer do I have to wear mask in public” will depend on herd immunity.
Herd immunity occurs when enough people become immune to a disease to make its spread unlikely. As a result, the entire community is protected, even those who are not themselves immune. Herd immunity is usually achieved through vaccination, but it can also occur through natural infection.
Dr. Elizabeth Kidder, The Chautauqua Center medical provider, said once 70% to 75% of county residents are vaccinated then herd immunity should be present in the community.
