A company in Cardiff has developed a test for coronavirus T cells – which can potentially provide longer-term immunity to the virus than antibodies.
The body develops T cells when fighting an infection and they can create more antibodies if a person is exposed again.
This means the immune system could remember how to fight Covid-19 even after original antibodies have faded.
Indoor Biotechnologies is “hopeful” the test will help in vaccine development.
It has received almost £50,000 in funding from Innovate UK, a research scheme supported by the UK Government.
The company’s trials found some people who had coronavirus but tested negative for antibodies went on to test positive for T cells – meaning more people may have some immunity than previously thought – and for longer.
