Doctor explains why Novak Djokovic is wrong to claim he's protected by antibodies
It’s just over a year since the UK’s coronavirus vaccine programme began, saving well over 100,000 lives, as well as preventing countless others from ending up in hospital and suffering long-term damage from Covid
Dr James claimed that ‘the science is not strong enough’ and that he didn’t need a vaccine because he had antibodies, showing he had acquired some ‘natural’ immunity through infection. A study published in December, by researchers from Imperial College London, concluded that the protection against Omicron, if you have had a prior Covid infection ‘may be as low as 19 per cent’. A course of vaccines — the double dose plus the booster — on the other hand, offers something like 75 per cent protection.
The first time your immune system encounters a virus it isn’t quite sure how to react and it takes time to start building an effective response. While that is happening, the virus is busy replicating, spreading and doing damage. Multiple exposures seems to be particularly effective at educating your T-cells, immune cells responsible for seeking out and killing dangerous viruses, and which are vital for conferring long-term immunity. T-cells also seem to be much better than antibodies at detecting and destroying new variants of Covid.
