The people who carry the gene are less likely to experience a breakthrough infection Vaccines are the best way people can protect themselves against Covid but experts said that ones with a particular gene have a bigger antibody response following vaccination than others.
Pointing out at a gene called HLA-DQB1*06, scientists say ‘About 30 to 40% of the UK population have this type.’ The people who carry this gene are less likely to experience a "breakthrough infection" over this time period.
But there are many other factors that contribute to the risk of getting Covid, including age, other illnesses and people's occupations.
They found those who had the gene variant were less likely to experience a "breakthrough infection" over this time period, where people still got a mild Covid infection after vaccination.
