Artist and biologist David Goodsell has done a painting of the Covid-19 mRNA vaccine.
The vaccine structure is highly idealized, with spike mRNA in magenta, lipids in blue, and PEG-lipid in green. The background is blood serum or lymph.
Both the Pfizer/BioNTech and the Moderna Covid-19 vaccines are based on mRNA — you can brush up on how they work at Stat or the CDC.
mRNA vaccines are a new type of vaccine to protect against infectious diseases. To trigger an immune response, many vaccines put a weakened or inactivated germ into our bodies. Not mRNA vaccines. Instead, they teach our cells how to make a protein — or even just a piece of a protein — that triggers an immune response inside our bodies. That immune response, which produces antibodies, is what protects us from getting infected if the real virus enters our bodies.
