What you need to know about the new coronavirus strains and how to protect yourself

Across the world, new coronavirus strains have started to emerge. The coronavirus and its viral variants known as COVID-19 (or SARS-CoV-2) became more infectious.

In South Africa, the coronavirus case rate doubled from the new virus strain. Hospitals filled up at twice the speed; doctors and scientists knew the virus had mutated. Geneticists and virologists sequenced the genome and identified a new virus strain. For scientists on the ground, the virus mutated overnight.

How do Messenger Ribonucleic Acid (mRNA) Vaccines Work?

The promising COVID-19 mRNA vaccine is unique compared to vaccines you may know.

While some vaccines—like the flu vaccine—use a whole virus or bacterium to help build immunity to pathogens, mRNA vaccines work differently.

Recombinant vaccine technology employs yeast or bacterial cells to make many copies of a particular viral or bacterial protein or sometimes a small amount of that protein.

mRNA vaccines bypass this step. They are chemically synthesized to simplify production and carry the information that enables cells to make the pathogen’s proteins or protein fragments themselves. The immune system then responds to these proteins and develops the tools to react to future infections with the pathogen.
