Scientists announced on Wednesday that they are now hoping for a successful Covid-19 vaccine after voluntaries showed signs of immunity in separate trials.
The UK and US trials have shown positive results with scientists now hoping the vaccine could end the virus that has killed hundreds of thousands of people worldwide.
Oxford University’s UK team of scientists focused on T-cells that develop as a result of a long-lasting immune response and confirmed on Wednesday that they are “80%” confident that they will have a great working vaccine by September.
Oxford University, which performed the study in collaboration with the pharmaceutical giant AstraZeneca, will mass-produce the medication when it is ready 100 per cent.
The vaccine produced an immune response in 45 healthy volunteers during the early-stage study, according to the scientists who revealed their findings in the New England Journal of Medicine (NEJM).
The scientists also confirmed that volunteers who obtained two doses of the vaccine had high levels of antibodies that surpassed those seen in Covid-19-recovered patients.
Both vaccines operate by tricking the body into thinking that the virus has been contaminated to cause an immune response that can then combat the virus.
Both vaccines work by tricking the body into believing that the virus has been infected to cause an immune response which can then attack the virus.
Scientists say that they have started to focus on T-cells also known as “memory” cells, which are made in response to an infection and remain long afterwards, unlike antibodies.
In an interview with ITV News on Wednesday, One of the Scientists working on the vaccine said;
“An important point to keep in mind is that there are two dimensions to the immune response: antibodies and T-cells.
“Everybody is focused on antibodies but there is a growing body of evidence suggesting that the T-cells response is important in the defence against coronavirus.”
