Is herd immunity a realistic concept? Fauci calls it 'elusive' and 'mystical'

Is herd immunity a realistic concept? Fauci calls it ‘elusive’ and ‘mystical’
Posted on
Of all the moving goal posts in the COVID-19 pandemic, herd immunity may be the most difficult to pin down and it may even be the wrong metric to track.
Herd immunity is the concept that once a majority of the population has been vaccinated or has natural immunity to an infectious disease, in this case SARS-CoV-2, life will shift back to normal.
But to listen to Dr. Anthony Fauci, President Joe Biden’s chief medical adviser and the head of the National Institute of Allergy and Infectious Diseases, is to hear him downplay the focus on this “elusive” concept and instead urge Americans to pay attention to other figures like vaccination rates. ....

When will we reach herd immunity? Experts answer when California and the US could reach threshold

Roadblock no. 1 to herd immunity: COVID-19 variants
First of all, let s talk about the variants.
Viruses mutate constantly, so most mutations do nothing, said Wachter. What we re seeing now with the U.K., the Brazilian and the South African variant is interesting, because it shows that variants can change in all sorts of ways. They can make (viruses) more infectious, they can make them more serious meaning equally infectious, but if you happen to get it you re likely to get sicker and/or they can make them resistant to immunity.
Any or all of those things are concerning because they make herd immunity harder to attain. Take the U.K. variant, which is said to be about 50% more infectious than last year s predominant strain. That means you d need to vaccinate more people to really curb its spread. Variants that are resistant to immunity would provide an even bigger challenge and force a real re-tinkering of the vaccine. ....
