How personalised cancer vaccines work

1

Biopsy

A biopsy of a patient’s tumour is sent to a lab, where its genetic material is sequenced to identify mutations not present in healthy cells

Tumour

Cancerous

mutations

3

Selection

Instruction

An algorithm identifies which mutations are driving the cancer’s growth and are likely to trigger the immune system

A molecule of messenger RNA (mRNA) is created containing instructions for making antigens that will cause an immune response

4

Injection

Once injected, the mRNA is translated into protein pieces identical to those found on tumour cells. Immune cells encounter these and destroy cancer cells carrying the same proteins
