Hopes for a vaccine against the emerging coronavirus (Covid-19) have increased after tests in Britain and America confirmed promising results. And revealed the research teams at both the University of Oxford and the British company "Moderna" that the people who have undergone tests showed signs of immunity to the virus.
The two teams have been developing experimental vaccines for several months to protect millions of people from contracting the Coruna virus in the future.
Oxford scientists said they are 80% confident they will produce the vaccine by next September. The people who took the Oxford vaccine had developed antibodies and white cells called "T-cells" that help human bodies to fight the virus when infected, according to the researchers.
Experts at the "Moderna" company, whose location is Massachusetts, said that the participants in its experiments have achieved great success in the production of antibodies.
The vaccine works by causing the body to think that it is infected with the Coronavirus, which causes it to generate immune materials that have the ability to destroy the virus. Although initial research focused on antibodies, scientists are now focusing on a model of immunity called T cell immunity, which is controlled by white blood cells, and which has shown promising signs.
A source from the Oxford project told ITV News: "An important point that we must bear in mind is that there are two dimensions in the immune response, which are antibodies and T cells."
"Everyone focuses on antibodies, but there is increasing evidence that T cells response is very important in defending against the Corona virus," he added.
And participated in the experiences of Oxford about eight thousand people from across Britain in addition to six thousand in Brazil, and South Africa, where it is easier to test the vaccine because there are large numbers of people infected with the Corona virus.
