The subject of vaccination in children continues to be a source of contention for many.

Australian Prime Minister Malcolm Turnbull recently proposed that immunisation rates for preschool and day-care centres should be made public, and parents to be denied the opportunity to make a formal objection to vaccination.

How do vaccines work?

Vaccines are made by infecting cells grown in tissue with a pathogen – the organism that produces the disease.

This virus or bacterium is then injected into the body, prompting the creation of antibodies.

Therefore, if a vaccinated person comes into contact with the disease – like measles or mumps for example – they already have immunity on the basis that they have the antibodies in their system to fight it. 

The case for vaccination

Diseases like smallpox and polio have all but been eradicated as a direct result of vaccination: in fact the latter was officially wiped out in 1980 and according to the NHS, if it was a common disease today; it would kill an estimated 2 million people every year.

Reddit user theotherdmund created a gif that demonstrates how contagious diseases pass through different populations depending on the percentage that is vaccinated. 

The reddit user used data from a study by The John Hopkins University School of Hygiene and Public Health.

Here it is, based on how much of the population is infected when 0 - 95 per cent are vaccinated:
