How does the vaccine work?
The Pfizer/BioNTech vaccine was the primary coronavirus jab to indicate promising ends in the latter levels of its testing course of.
It is a brand new kind referred to as an mRNA vaccine that makes use of a tiny fragment of genetic code from the pandemic virus to show the physique learn how to battle Covid-19 and construct immunity.
