Why did this happen? While the UK leaving Europe adds 'complexity' to the process, robust plans are in place to mitigate Brexit. The thinking behind it is different vaccines provoke different parts of the immune system  the main substances being antibodies and T cells. Picture taken November 29, 2020. This genetic material is then naturally absorbed by cells which it forces to produce the 'spike' proteins found on the outside of the virus.
feed cells in the bodies of animals is another way to artificially boost immunity.
