Ok, got a Christmas zoom with the family anti-vaxxer this week and I quite liked this passage from New scientist. However, can someone really dumb this stuff down? To primary level? And what else does the vaccine contain? Mercury is her usual go to.
"The active ingredient is messenger RNA that carries instructions for making the virus’s spike protein, which it uses to gain entry to cells. The mRNA is synthetic, not extracted from actual viruses. It is delivered in a tiny sphere of inert fatty material called a lipid nanoparticle.
The RNA-bearing nanoparticles are suspended in saline solution and injected into muscle tissue in the upper arm. The mRNA is then taken up by specialist immune cells, which follow its instructions to make the spike protein, just as they would do if they had become infected with the actual virus.
The spike protein is recognised as foreign by the immune system, which mounts an attack against it. Antibodies, B cells and T cells are activated, according to Uğur Şahin, the chief executive of the small German company BioNTech that co-developed the vaccine with US drug giant Pfizer. An immune memory is also laid down, he says, which means the immune system has learned how to defeat the pathogen and is primed to mount a swift response if it encounters the coronavirus again."
