What is Herd Immunity?

When you think of a herd, you probably think of cows, wildebeest or buffalo. In the animal world, there is safety in numbers – more pairs of eyes to look out for predators, for example.

As humans, we don't generally have to worry about predators, but we can gain the protection of the herd in other ways.

"Herd immunity" is the idea that, as long as enough people in a population are immune to a disease (usually through vaccination), they can indirectly protect people who aren't immune from getting infected.

Dr Adam Kucharski is an Assistant Professor of Epidemiology at the London School of Hygiene and Tropical Medicine, where he works on mathematical models of the spread and control of disease.

Microbiology Today is the Society's quarterly magazine. The content is balanced to meet the needs of the Society’s members. The magazine aims to provide informative and enjoyable broad-interest articles for all readers, including parliamentarians and policy-makers. Each issue focuses on a topic, and topics are chosen with the aim of covering all fields of microbiology.

The Microbiology Society is a membership charity for scientists interested in microbes, their effects and their practical uses. It is one of the largest microbiology societies in Europe with a worldwide membership based in universities, industry, hospitals, research institutes and schools.

Our principal goal is to develop, expand and strengthen the networks available to our members so that they can generate new knowledge about microbes and ensure that it is shared with other communities. The impacts from this will drive us towards a world in which the science of microbiology provides maximum benefit to society.

Herd immunity only works if you have a vaccine... but Coronav doesnt have a vaccine?

[IgnatiusVaz]

Well explained, but please attach the question too. We never got to know what question was being answered.

[christinecampbel]

Anyone else here in 2021 watching this waiting for all of this to be over? 😩

[stevetaylor]

The music was too loud, making it difficult for me to understand. Why do the producers do this? Don't they know?

[MissAwa]

So while there is still a long way to the COVID-19 vaccine, how does Britain do the Herd Immunity now?

[MrQuimane]

Yea but this vaccine today was rushed and not enough time to know all side effects short and long term, and also plotted,

If this video were made a few years later, there would be CDC banners posted all over it.

[MAbduser]

The background music is like we're prisoners who are to be executed, suddenly, someone from outside the prison wanted to help us escape the prison. He stood there and started to teach us how to escape, and while he's teaching us how to do it, he plays on his violin to keep us entertained :D
