Those with the blood group O reportedly have the lowest likelihood of catching Covid-19, and the new top-up jab should provide relief against sub-variants of the disease.
By now, most of us have been stricken by Covid, but 15% of people in the UK have evaded the virus. According to a testing expert at the London Medical Laboratory, the great escape is down to three factors: blood group, vaccines, and lifestyle.
Having assessed the findings of recent Covid-19 blood type studies, Dr Quinton Fivelman PhD, Chief Scientific Officer at London Medical Laboratory (LML), believes that people with the blood group O are less likely to be infected than those with other blood groups, while those with blood type A are far more likely to contract the virus.
‘There have now been too many studies to ignore which reveal that people have a lower chance of catching the virus, or developing a severe illness, if they have blood group O,’ he said.
Indeed, research from the New England Journal of Medicine had previously found that those with blood type O were 35% less likely to be infected, whereas those with Type A were 45% more vulnerable. A further benefit of type O blood is the reduced risk of heart disease compared to those with type A or B blood.

According to the NHS, almost half of the population (48%) has the O blood group; so, clearly, other factors come into play in terms of our susceptibility. Dr Fivelman said: ‘By far the most important factor is the number of antibodies you carry, from inoculations and previous infections, together with your level of overall health and fitness.’
So, those who are more careful about visiting crowded places, who eat well, and are fortunate enough not to have an underlying illness have better chances of avoiding Covid-19. According to LML, having been vaccinated also helps, though these benefits have slowly worn off. That is why the new top-up jab with the Omicron variant could provide some relief for those who take it.
‘The new Omicron jab has come none-too-soon, so many people are now suffering repeated Covid infections,’ he added. ‘That’s because the new Omicron BA.4 and BA.5 sub-variants do not produce as high an immune response as the previous strains, so re-infection is more likely to occur.
‘Higher levels of antibodies are important to neutralise the virus, stopping infection and limiting people transmitting the virus to others.’
