Why Vaccinate? The history and science of vaccination

Sunday 25th Oct 2015, 08.30am

This podcast is part of the Vaccines: From Concept to Clinic series.

Vaccines are arguably the most successful medical interventions in human history saving millions of lives annually and contributed significantly to the elimination of one of the world’s most deadly diseases, smallpox. In this episode we cover the origins of vaccination and the science behind how vaccines work. We also discuss how common misgivings about vaccination can lead to dangerous outbreaks of infectious disease.

Were you wondering...

If some diseases have been eradicated by using vaccines, why can't we just do this for all diseases?

Sean says:

"We would love to eradicate world disease but in reality this is easier said than done. Firstly successful strategies used for one disease don’t always work for another. The fight against disease is also an arms race, pathogens evolve to avoid strategies as we develop new ones. Money is the final major issue. There are only so many scientists working in the field and they are often competing for funding. There is also disparity in funding availability, with the diseases that are major killers getting the bulk and niche diseases which kill less people receiving a lot less, despite possibly being easier to target."
