  • Herd Immunity is Only Possible with a Vaccine by Bernadette Boden-Ablala, MPH, DrPH; Dan M. Cooper MD; Clayton Chau, MD, PhD; Casey Dorman, PhD
    • There has been much debate around the concept of herd immunity since the early stages of the COVID-19 pandemic. As a public health term, the idea of herd immunity is that if enough people are protected against an infection because they have been exposed and developed antibodies, transmission of the infection slows and ultimately new outbreaks are halted because much of the population is no longer susceptible. Some people suggest that COVID-19 can best be controlled by allowing the virus to run its course and achieve enough numbers of infected persons to reach herd immunity. We suggest that there is some confusion about the use of this term and that there are strong reasons for not pursuing that approach. READ MORE
