During the Covid crisis I upgraded my knowledge about how vaccination and herd immunity works. Essentially vaccination makes the individual's immune system respond more quickly to infection. But if the virus or bacterium exposure is very high it could 'beat' the immune system in an individual.
Of course the more people in the population not vaccinated, the easier it is for the disease to spread in the population, increasing the exposure of the pathogen we all experience. Eventually if enough people fail to be vaccinated we reach a tipping point, and a pandemic may emerge.
Worryingly increasing numbers of kids are not getting routine vaccination. The problem is worst in London. This needs a serious up-step on education.
In addition, it concerns me that conscientious vaccinated folk run the risk of serious disease because ignorant and/or deluded parents are not getting their kids vaccinated. Perhaps we need laws to ensure that kids cannot attend state school if they are not vaccinated. Unfortunately the thickies will probably embrace home schooling. Much of this has been propagated by fake news websites and the arse who triggered the MMR/autism disaster.

Child vaccinations: Low uptake prompts tipping-point warning
There are concerns over the spread of diseases such as whooping cough in England, as vaccine rates fall.
