Hello I heard on the telly the other day that this vaccine is based on an Edward Jehnna smallpox vaccine from 1700s ,it wiped out small pox hopefully it will do the same for coronovirus jezza
That's true but it's a bit like comparing a Tesla with a steam engine! The technology that has developed these vaccines was undreamed of in the 1700s and is even far in advance of what was possible just 20 years ago.
