‘Significant number’ of Brits are naturally immune to coronavirus – without ever being infected
A 'significant number' of Brits might already have immunity to coronavirus an expert has suggestedagainst the new bug.
But more importantly, those T-cells die off in older people, which could explain why the elderly are at higher risk of severe illness.Sir John, who is leading a team developing a vaccine at Oxford, told the Commons science and technology select committee that these T-cells coud be found in a "significant number of people".
The vaccine being developed by his team has been found to boost T-cell response, as well as stimulate antibodies. "I think you have to keep an open mind about whether you have a large number of people who have protective T-cells in the absence of antibodies."Sir John also warned that the UK must "prepare for the worst" this winter, instead of relying on the development of a successful coronavirus vaccine.
