I could get very sick. It was discovered that some were carrying a genetic mutation that produces a messed-up version of the protein called the CCR5 receptor, one of the proteins that HIV uses to gain entry to a cell and make copies of itself. After ten weeks, the Pfizer booster was 35 per cent effective, and the Moderna booster 45 per cent effective.

So far the booster programme is a roaring success, with more than half the population receiving a vital third dose offering at least 70 per cent protection against symptomatic infection with Omicron. Tiny micro-needles in the patch painlessly puncture the skin, allowing fragments of a range of viral proteins to seep through into the bloodstream and spark the release of anti-coronavirus T cells.

Another complication could arise from the global nature of the project; the cohort will be massively heterogeneous. Now that they have a substantial cohort, the group will take a twofold approach to hunting for a genetic explanation for resistance. Some T-cells help B cells, which are also part of the immune system, produce more mature antibodies, while others go after cells infected with a virus. When the UCL researchers examined the blood of seemingly Covid-proof healthcare workers that had been taken before the vaccine rollout, it confirmed they had no Covid antibodies meaning it was unlikely they had ever been infected.
