This genetic material is then naturally absorbed by cells which it forces to produce the 'spike' proteins found on the outside of the virus. The Pfizer and BioNTech vaccine is one called an mRNA vaccine. 'So the idea of trying to mix and match is so that you can maximise the strength of that immune response to protect people against viral infection.' Oxford and AstraZeneca's, however, is a more traditional type of jab that carries the genetic material in a harmless chimpanzee virus, called an adenovirus, instead of the fat droplet. The thinking behind it is different vaccines provoke different parts of the immune system  the main substances being antibodies and T cells.
