South Africa at the start of a Covid-19 vaccine the world has never seen - The World Health Organisation has enlisted a team of South African researchers to produce a new mRNA Covid-19 vaccine, but with no recipe to follow, it’s not an easy task

. In 2010, children in countries such as Morocco and Algeria missed out on life-saving meningitis vaccines amid a global shortage.

They hope to produce a prototype for testing in the next year that is adapted to new variants and that, unlike current brands, does not need the ultra-cold storage that poses problems for developing countries without sophisticated refrigeration systems.Historically, vaccines have worked by using harmless versions of a germ — or proteins designed to look like a virus — to trick the body into churning out antibodies to fend off future illness.

In the case of mRNA vaccines, this code teaches cells how to produce the proteins needed to mount a defence against SARS-CoV-2. This response snowballs, growing bigger and triggering different responses by your immune system. Naked mRNA degrades quickly. If mRNA in a vaccine disappears too soon, it won’t stick around long enough in the body to make the proteins needed to spark an immune response.
