Vaccines are complex to make

Technology is enabling new methods of exploring vaccine candidates for trial, but there are already a few tried and tested ways to make them.

In all of them, scientists try to stimulate the body’s immune system to combat invasive pathogens. That’s commonly done by creating something so similar to the pathogen that the body begins to create antibodies to fight off the real thing.

The most common way of doing this is to make what’s called attenuated vaccines – those that are made of weaker strains of the actual pathogen. Reared on animal cells outside of human bodies (some flu vaccines are cultured on chicken eggs), they are then extracted and injected in a single tiny dose.

Vaccines for measles and tuberculosis are created in this way.
