There has been one common goal for bringing the pandemic to an end since the beginning: achieving herd immunity.

When a virus infects so many people that it runs out of potential hosts to infect, the outbreak sputters out.

“It’s very complicated” to meet a clear herd-immunity target, according to Dr.

Jefferson Jones, a medical officer with the Centers for Disease Control and Prevention’s COVID-19 Epidemiology Task Force.

He said that thinking in terms of “a strict goal” is something that “we would discourage.”

It was a sobering new message, according to Oliver Brooks, a member of the CDC’s Advisory Committee on Immunization Practices.


Jones’ unexpected admission, he added, “almost makes you less motivated to get more people vaccinated.”

Brooks is concerned that the CDC’s decision to abandon a specific target for herd immunity will deflate vaccination efforts.

And if officials from the Department of Health and Human Services stop talking about the..
