With Post wires The traditional way of making a vaccine would involve growing a pathogen in bulk before injecting a small, neutralised amount of virus or bacterium into patients, whose immune systems would react to the antigens on its surface and develop antibodies that could ward off the disease. In South Africa, it has rapidly become dominant in the countrys coastal areas. Vaccines work by preparing the bodys immune system so that if it encounters the virus, it recognises it immediately. After a person has been vaccinated, they may have sufficient neutralising antibodies circulating in their bloodstream to destroy a virus before it can cause infection.
