The experts behind the BioNTech coronavirus jab have developed another vaccine which they claim cures multiple sclerosis (MS) in mice. The new MS vaccine works in a similar way to the coronavirus vaccine, manufactured in conjunction with US pharmaceutical giant Pfizer. A piece of genetic material known as mRNA is inserted into a person's arm and forces the body's own cells to produce a protein that confers immunity. In the case of the coronavirus vaccine, this protein mimics the virus's protruding spike, kickstarting the immune system to start making antibodies. If a person later contracts the coronavirus, the immune system rapidly creates antibodies again and fights the infection before it can take hold or spread.
