Herd immunity and COVID-19 (coronavirus): What you need to know
www.mayoclinic.org...
Vaccines
Herd immunity also can be reached when enough people have been vaccinated against a disease and have developed protective antibodies against future infection. Unlike the natural infection method, vaccines create immunity without causing illness or resulting complications. Using the concept of herd immunity, vaccines have successfully controlled contagious diseases such as smallpox, polio, diphtheria, rubella and many others.
Herd immunity makes it possible to protect the population from a disease, including those who can't be vaccinated, such as newborns or those who have compromised immune systems.

How is the rollout going?
So far, more than 47 million people have had a first vaccine dose - 87% of over-16s - and nearly 41 million - 75% of over-16s - have had both doses.
The number of first doses administered each day is now averaging about 41,000 - far below a peak of some 500,000 in mid-March.
An average of more than 160,000 second doses are now being given a day. The delivery of second doses had been accelerated in response to the emergence of the Delta variant, first identified in India.
When does vaccinate herd immunity kick in?

How can the vax provide herd immunity when it does not stop infection?
It stops or vastly reduces the risk of serious illness or death. That's herd immunity.

This professor explains why there is nothing to worry about because the body does not require advance warning from a vax.....he shows how he knows this.

It stops or vastly reduces the risk of serious illness or death. That's herd immunity. A bit like how the flu shot works, it prepares your immune system to fight it off quicker and gives you a better chance against differing strains.
About three-fourths of the 469 infections were among vaccinated people.

That's not herd immunity, and even if it was, it's still not doing that!
